直到VMware ESX(i) 4.0 U2，官方的VMware-tools都未提供对FreeBSD 8.0 amd64的支持，因此改为安装Open Virtual Machine Tools。

[root@yaoge123 ~/vmware-tools-distrib]# uname -a
FreeBSD yaoge123 8.0-RELEASE-p3 FreeBSD 8.0-RELEASE-p3 #0: Tue May 25 20:54:11 UTC 2010     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64
[root@www ~/vmware-tools-distrib]# ./vmware-install.pl
Creating a new VMware Tools installer database using the tar4 format.

Installing VMware Tools.

……
Before running VMware Tools for the first time, you need to configure it by
invoking the following command: “/usr/local/bin/vmware-config-tools.pl”. Do you
want this program to invoke the command for you now? [yes]

Initializing…

Stopping VMware Tools services in the virtual machine:
Guest operating system daemon:                                      done
Unable to copy the source file
/usr/local/lib/vmware-tools/modules/binary/FreeBSD8.0-amd64/vmxnet.ko to the
destination file /boot/modules/vmxnet.ko.

Execution aborted.

[root@www ~/vmware-tools-distrib]# cd /usr/local/lib/vmware-tools/modules/binary/
[root@www /usr/local/lib/vmware-tools/modules/binary]# ls
FreeBSD6.0-amd64        FreeBSD6.3-amd64        FreeBSD7.0-amd64        FreeBSD7.3-amd64
FreeBSD6.0-i386         FreeBSD6.3-i386         FreeBSD7.0-i386         FreeBSD7.3-i386

首先确认是否安装了内核源代码，如果您的系统中没有 /usr/src/sys 这样一个目录， 则说明没有安装内核源代码。安装它最简单的方法是通过以 root 身份运行 sysinstall， 选择 Configure – Distributions – src，选中其中的 base 、sbin和sys。如果提示Warning:  Can’t find the `8.0-RELEASE-p3′ distribution on this……，在Configure – Distributions – Options中修改Release Name为8.0-RELEASE，安装完成后用freebsd-update fetch install更新源代码。

然后再安装Open Virtual Machine Tools
cd /usr/ports/emulators/open-vm-tools-nox11
make install clean

至少支持了使用VMware Tools关机（这是HA所必不可少的）和vmxnet2网卡。

　　FreeBSD安装了VMware Tools以后，可以通过VI关闭客户机，但是系统停留在“The operating system has halted.Please press any key to reboot.”不能够自动关闭电源。解决方法为
ee /usr/local/etc/rc.d/vmware-tools.sh
　　查找vmware_start_guestd()可见
vmware_start_guestd() {
cd "$vmdb_answer_SBINDIR" && "$vmdb_answer_SBINDIR"/vmware-guestd \
--background "$GUESTD_PID_FILE"
}
　　在vmware-guestd命令下增加参数–halt-command “/sbin/shutdown -p now”，修改为
vmware_start_guestd() {
cd "$vmdb_answer_SBINDIR" && "$vmdb_answer_SBINDIR"/vmware-guestd \
--background "$GUESTD_PID_FILE" --halt-command "/sbin/shutdown -p now"
}
　　保存退出。执行 /usr/local/etc/rc.d/vmware-tools.sh restart，重启vmware tools即可。
