Kernel components
     __________________________________________________________________

vmblock

   This is a Linux kernel filesystem module. Internally, we've built it as
   far back as 2.4.2, and we believe it to be generally compatible with
   all 2.4 and 2.6 kernels. Ideally, it should be loaded before any of the
   Tools userlevel components are allowed to start, though vmblock itself
   has no dependencies. When loaded, vmblock will establish itself in
   /proc/fs/vmblock and create two nodes therein, dev and mountPoint.
   Before mounting a vmblock filesystem, ensure that /tmp/VMwareDnD exists
   as a directory with permissions 1777, otherwise host to guest drag n'
   drop operations won't work.
   To mount, issue:
mount -t vmblock none /proc/fs/vmblock/mountPoint

   Once mounted, vmware-user can begin to make use of vmblock to assist
   with DnD operations. Note that while vmware-user is running, it'll keep
   an open file descriptor on /proc/fs/vmblock/dev, and thus all
   vmware-user instances must be killed to unmount and unload vmblock.

vmhgfs

   This is also a Linux kernel filesystem module. Like vmblock, we've
   built it as far back as 2.4.2 and believe it to be compatible with all
   2.4 and 2.6 kernels. None of the Tools components depend on vmhgfs, nor
   does it have any dependencies of its own, so it can be loaded at any
   time in the boot process.
   When mounting, one must use an NFS-like "<host>:<export>" syntax. The
   <host> field must be ".host", while the <export> field can be "/", a
   path to a specific Shared Folder, or a path to a subdirectory within
   that Shared Folder. To mount, you must first build vmware-hgfsmounter
   and install it setuid as /sbin/mount.vmhgfs, otherwise the mount
   program won't properly call out to it. Note that mounting may fail if
   Shared Folders are disabled in the host; don't be alarmed. The vmhgfs
   filesystem supports a plethora of mount options, run vmware-hgfsmounter
   -h to see them. We typically exclude vmhgfs from the locate database as
   crawling the Shared Folders is time consuming. To do this, add "vmhgfs"
   to PRUNEFS within updatedb's configuration file, typically found in
   /etc/updatedb.conf.
   We also typically mount vmhgfs via:
mount -t vmhgfs .host:/ /mnt/hgfs

   Or by adding this line to /etc/fstab:
.host:/   /mnt/hgfs   vmhgfs  defaults  0 0

   The net effect is that all Shared Folders appear and disappear at
   /mnt/hgfs as they're added or removed.

vmmemctl

   This is a Linux kernel module. It isn't backed by a virtual hardware
   device, so it must be loaded manually. It has no dependencies, nor do
   any Tools components depend on it, so it can be loaded at any time
   during the boot process. Once loaded, no further action is needed.
   We've successfully built vmmemctl as far back as 2.2.16, and we believe
   it to be generally compatible with all newer kernels as well.

vmxnet

   This is a Linux kernel device driver module that drives VMware's fast
   networking device. As it is backed by real (virtual) hardware, it
   should be automatically loaded by hotplug or udev as needed. For best
   performance, it is recommended to enable TSO on all interfaces driven
   by vmxnet using ethtool.
   The shell code to do this might look like this:
if which ethtool >/dev/null 2>&1; then
   for ethif in `ifconfig -a | grep ^eth | cut -d' ' -f1`; do
      ethtool -K $ethif tso on >/dev/null 2>&1
   done
fi

   The VMware backend may present the fast networking device as an AMD
   vlance device instead of the actual vmxnet device. If your kernel boots
   using initrd, and the pcnet32 device driver is in it (pcnet32 drives
   AMD vlance devices), you should also add vmxnet to the initrd.
   Otherwise, it is possible that vmxnet will not be loaded. To have
   vmxnet "morph" the vlance device into the fast networking device, make
   the following modifications.
     * If using modutils, some modifications to modules.conf are needed.
       For each network interface in the VM, add the following line,
       substituting <interface-name> with the name of the interface:

alias <interface-name> vmnics

   If there was at least one such interface, also add:
probeall vmnics vmxnet pcnet32
     * If using module-init-tools, add the following to modprobe.conf, to
       modprobe.conf.local, or as a new file within modprobe.d (whichever
       is appropriate for your distribution):

install pcnet32 /sbin/modprobe -q --ignore-install vmxnet; /sbin/modprobe -q --i
gnore-install pcnet32 $CMDLINE_OPTS; /bin/true;
     * If using hotplug, you'll also need to modify
       /etc/hotplug/pci.handmap so that hotplug will load vmxnet if it
       detects a fast networking device. Add the following line to the end
       of the file:

vmxnet\t\t0x000015ad 0x00000720 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0

vmxnet3

   This is a Linux kernel device driver module that drives VMware's second
   fast networking device. As it is backed by real (virtual) hardware, it
   should be automatically loaded by hotplug or udev as needed. Unlike the
   older 'vmxnet' hardware, the 'vmxnet3' hardware does not morph and as
   such the above modprobe-related logic isn't necessary. The module is
   expected to build for kernels 2.6 and newer.

vmsync

   This is a Linux kernel module. It isn't backed by a virtual hardware
   device, so it must be loaded manually. It is depended on by
   vmware-guestd, so ideally it should be loaded prior to starting
   vmware-guestd (though vmware-guestd can function without it). This
   module is used for freezing and thawing the filesystem, and is only
   relevant for kernel versions 2.6.6 and newer (it was in 2.6.6 that the
   underlying freeze/thaw functionality that vmsync uses was added to
   Linux). It won't build against older kenels.

vmci

   This is a Linux kernel device driver module that drives VMware's
   inter-VM communication device. The device itself is backed by a
   PCI-based virtual hardware implementation, so hotplug or udev should
   load it at guest boot time in any VMs using hardware version 7. The
   module is expected to build for all kernel versions 2.4 and later.

vsock

   This is a Linux kernel device driver module that provides datagram and
   stream socket interfaces to the underlying VMCI device. The module
   implements a Linux socket family and one of the files in the module,
   vmci_sockets.h, provides the various constants and functions necessary
   to create and, in the case of streams, connect sockets. The modulei s
   expected to build for all kernel versions 2.4 and later.
   The vsock module needs some attention from package maintainers if it is
   to be installed properly:
     * When the module is loaded, /dev/vsock will be created with
       restricted permissions. Access to /dev/vsock is required to use
       VMCI sockets, so it's recommended that permissions be relaxed via a
       udev policy file. For reference, the VMware Tools init script
       changes the permissions of /dev/vsock to 666.
     * Normally, issuing a socket(2) system call will automatically load
       the kernel module providing that socket family, but as the vsock
       module is out-of-tree, there is no in-tree socket family
       reservation for VMCI sockets. Before sockets are created, userspace
       applications must call VMCISock_GetAFValue (defined in
       vmci_sockets.h) which will instruct the vsock module to dynamically
       acquire a socket family reservation from the kernel. This function
       is implemented via ioctl(2) into the vsock module, so the vsock
       module must be manually loaded by the user (perhaps using
       /etc/modules).
     * The vmci_sockets.h header should be installed in a system-wide
       location. We recommend /usr/include/vmci.
     * The vsock module depends on symbols from the vmci module, and so
       the vmci module must be loaded first.

User level components
     __________________________________________________________________

vmware-guestd

   This is a userlevel daemon process. It should build successfully on
   Linux (against glibc-2.1 and later), on FreeBSD (FreeBSD 3.2 and
   later), and on Solaris (Solaris 9 and later). It expects to be run as
   root, and has no dependency on X, so it can run in the console.
   On Linux, VIX user impersonation is only possible by creating
   /etc/pam.d/vmware-guestd with the following contents (adding "64" as a
   suffix of "lib" if appropriate):
#%PAM-1.0
auth       sufficient       /lib[64]/security/pam_unix2.so shadow nullok
auth       required         /lib[64]/security/pam_unix_auth.so shadow nullok
account    sufficient       /lib[64]/security/pam_unix2.so
account    required         /lib[64]/security/pam_unix_acct.so

   For vmware-guestd to run the default soft power operation scripts, they
   must be installed to /etc/vmware-tools with the executable bit
   activated.
   By default, vmware-guestd will broadcast the internal VMware Tools
   backdoor version (the numerical value of TOOLS_VERSION_CURRENT defined
   in vm_tools_version.h) to various VMware UIs and the VI SDK. This value
   is used for upgrading decisions, but VMware's current product set
   cannot upgrade open-vm-tools based packages. As such, it's important to
   prevent such upgrades, by creating a configuration file for
   vmware-guestd (named /etc/vmware-tools/tools.conf) with the following
   contents:
disable-tools-version = TRUE

   This will cause vmware-guestd to broadcast the highest possible
   backdoor version, which will in turn "trick" all clients into thinking
   that the Tools are up-to-date and do not require an upgrade.

vmware-user

   vmware-user is a relatively small Gtk application that should run for
   the duration of an interactive X11 session. It has no dependencies on
   X11 service daemons (e.g., messaging buses), and so it may be launched
   at any time during or after session startup.
   Without a running vmware-user process, interactive X11 sessions will
   lack GUI features such as drag-and-drop (DnD), file and text
   copy/paste, dynamic display resizing, and Unity.
   It should build successfully on Linux (glibc-2.1 and later, using
   gtk-1.2), on FreeBSD (FreeBSD 5.3 and later, using gtk-1.2), and on
   Solaris (Solaris 10 and later, using gtk-2.0). At the time of writing,
   vmware-user does not support multiple concurrent users (that is, no
   fast-user switching). As a gtk app, it depends on the presence of
   certain common gtk shared objects (glib and gtk-1.2, among others) at
   runtime.
   On Linux, vmware-user depends on a mounted vmblock filesystem as
   described above for proper host to guest DnD operations.
   Drag-and-drop operations depend on a setuid wrapper,
   vmware-user-suid-wrapper, described below.
   X11 Autostart (Linux, FreeBSD)
   A recent change for Linux to the Open VM Tools adjusted the nature of
   the relationship between the VMware Tools service (vmware-guestd) and
   the VMware user process (vmware-user). The two programs have been
   completely decoupled, and as such vmware-guestd no longer attempts to
   automatically start and stop vmware-user processes on users' behalf.
   (This behavior is consistent with that of FreeBSD and Solaris.)
   It's up to the Open VM Tools package maintainers to determine how to
   best hook vmware-user into their users' X11 sessions. The following
   information may help.
   Modern display managers implementing the [109]XDG autostart spec
   support launching applications at session startup via placing a
   `vmware-user.desktop' file in a well-known location (e.g.,
   /etc/X11/autostart or /usr/local/share/autostart). (An example file is
   reprinted below.)
[Desktop Entry]
Encoding=UTF-8
Exec=vmware-user
Name=VMware User Agent
X-KDE-autostart-phase=1
NoDisplay=true

   Other display managers, such as gdm (older versions) or xdm, may
   instead require tweaking your distribution's Xsession (if applicable)
   script.
   X11 Autostart (Solaris)
   Add a symbolic link to vmware-user within /usr/dt/config/Xsession.d.

vmware-user-suid-wrapper

   Operations on the vmblock filesystem are considered privileged, and as
   such may only be issued on a file descriptor acquired by root. This is
   accomplished by vmware-user-suid-wrapper, a small setuid wrapper whose
   only purpose, on Linux, is to acquire a filesystem file descriptor,
   drop superuser privileges, and then execute vmware-user. On FreeBSD and
   Solaris, it does all of the above, but is also tasked with managing the
   vmblock module. (Specifically it will reload the module and reload the
   filesystem in order to keep vmblock and vmware-user in sync.)
   The path to vmware-user used by this wrapper is defined at compile
   time. By default, it's $(bindir)/vmware-user, but may be overridden by
   defining the make variable VMWARE_USER_PATH.

vmware-toolbox

   This is a per-user process that, like vmware-user, must be run in an
   X11 session, and isn't needed otherwise. Also like vmware-user, it does
   not support multiple concurrent users, and depends on certain gtk
   shared objects at runtime. It should build successfully on Linux
   (glibc-2.1 and later, using gtk-1.2), on FreeBSD (FreeBSD 5.0 and
   later, using gtk-1.2), and on Solaris (Solaris 10 and later, using
   gtk-2.0).

vmware-toolbox-cmd

   This is a simple console application that has very few system
   dependencies (though it does depend on guestlib, described below). It
   is highly portable and should build just about everywhere. It can be
   run as any user.

vmware-checkvm

   This is a simple console application. It should build successfully on
   Linux (glibc-2.1 and later), on FreeBSD (FreeBSD 3.2 and later), and on
   Solaris (Solaris 9 and later). It can be run as any user.

vmware-xferlogs

   This is a simple console application. It should build successfully on
   Linux (glibc-2.1 and later), on FreeBSD (FreeBSD 3.2 and later), and on
   Solaris (Solaris 9 and later). It can be run as any user.

vmware-hgfsmounter

   This is a console-based mount helper application. It is only necessary
   on Linux, as vmhgfs must be mounted by passing a binary blob to the
   driver. It should build successfully using glibc-2.1 or later. As
   described earlier in the vmhgfs section, vmware-hgfsmounter must be
   installed with setuid root permissions as /sbin/mount.vmhgfs.

vmware-hgfsclient

   This is a simple console application. It should build successfully on
   Linux (glibc-2.1 and later), on FreeBSD (FreeBSD 3.2 and later), and on
   Solaris (Solaris 9 and later). It can be run as any user.

guestlib

   This is a shared object intended for use in other applications. It
   should build successfully on Linux (glibc-2.2 and later), on FreeBSD
   (FreeBSD 3.2 and later), and on Solaris (Solaris 9 and later).

Other
     __________________________________________________________________

sound

   If you know that your distribution will run on pre-Workstation 5 VMs
   (such as Workstation 4.5, or ESX Server 2.5), you must modify
   /etc/modules.conf by replacing any instance of
alias char-major-14 <garbage>

   with
alias char-major-14 es1371

   and any instance of
alias sound <garbage>

   with
alias sound es1371

   Distributions using module-init-tools in lieu of modutils are probably
   new enough so as not to need these modifications.

gpm

   If gpm is installed, its configuration must be modified so that it will
   function properly with the virtual mouse. If your version of gpm
   supports the "imps2" protocol (which you can find out by running "gpm
   -t help"), you must replace MOUSETYPE and XMOUSETYPE within
   /etc/sysconfig/mouse with
MOUSETYPE=imps2
XMOUSETYPE=IMPS/2

Xorg setup

   Configuring X to run well under VMware is rather tricky, as there are
   quite a few pieces that can be matched up somewhat arbitrarily (the
   Xorg/XFree86 version, the virtual hardware version, and the svga guest
   driver version). For the sake of clarity, the instructions for
   configuring XFree86 older than 4.0.0 are omitted. The
   /etc/X11/xorg.conf or /etc/X11/XF86Config-4 file must be modified in a
   number of ways. Here they are, described section by section.
     * Mouse section:
          + Replace the Driver field's value with "vmmouse"
          + Add Option "Buttons" "5" if it doesn't already exist.
          + Add Option "ZAxisMapping" "4" "5" if it doesn't already exist.
          + Add Option "Emulate3Buttons" "true" if it doesn't already
            exist.
          + On Solaris, replace the Device field's value with
            "/dev/kdmouse".
          + On FreeBSD, replace the Device field's value with
            "/dev/sysmouse" if /etc/rc.conf has "moused_enable" set to
            "yes", or with "/dev/psm0" otherwise.
          + On Linux and Solaris, replace the Protocol field's value with
            "IMPS/2" if gpm was modified above, or with "ps/2" otherwise.
          + On FreeBSD, replace the Protocol field's value with "SysMouse"
            if /etc/rc.conf has "moused_enable" set to "yes", or with
            "ps/2" otherwise.
          + There is currently no standard way to detect the presence of
            the VMware mouse device. Ubuntu is implementing a custom one
            for Gutsy Gibbon using a 'vmware-detect' tool, and it is
            recommended that this mechanism be adopted by other
            distributions going forward.
     * Device section:
          + Replace the Driver field's value with "vmware".
          + Note that the existing X autodetect infrastructure should
            automatically detect the VMware video device. If so, the above
            modification isn't necessary.
     * Screen section:
          + There should be Display subsections for depths 4, 8, 15, 16,
            and 24.
          + Each subsection should set ViewPort to 0 0.
          + Each subsection should set Modes to a list of reasonable
            resolutions. With the most modern VMware video driver (10.15.0
            at the time of writing), the Modes list is only used by the X
            login manager anyway, and so isn't terribly important.
     * Monitor section:
          + VendorName should be "VMware, Inc".
          + HorizSync should be 1-10000.
          + VertRefresh should be 1-10000.

   It is possible that the X server will complain that no mouse device was
   configured. This may occur in Xorg 7.2, Xserver 1.3, and in some
   backported Xorg 7.1 releases (such as those shipped by Red Hat). A
   workaround is to add a dummy InputDevice. To do this, add the following
   to the configuration file:
Section "InputDevice"
        Identifier  "XWorkAround"
        Driver      "void"
EndSection

   Then tie the new InputDevice to the server's configuration by adding
InputDevice "XWorkAround"

   to the ServerLayout section.
