It runs Windows XP Pro SP2. I've never used XP as host OS for VMware server, but I have several FreeBSD guests on VMware server 1.0.3 (RHEL 4.x host) and ESX 3.x. FreeBSD 6.x runs fine as guest OS with one problem: SMP does not work with FreeBSD i386 guests. It does work well with am64 though.

For now I would suggest to start with 6.x and upgrade to 7.x when the time is right. :) > - Are there any gotcha's that i need to address to get an emulated > (32bit or 64bit, FBSD 6 or 7, etc) off the ground at all? No gotchas, it works except for the i386/SMP problem. Just a few tips: - use le(4) for the network interface instead of lnc(4) if you decide to use i386 (amd64 will get em(4), which works good) - set kern.hz="100" in your /boot/loader.conf - install VMware tools that are shipped with VMware server - after installing VMware tools move /boot/kernel/vmmemctl.ko to /boot/modules/ to avoid reinstalling the module after each kernel build - if you want to use both of your CPU-cores with 6.x, use amd64 - disk I/O will be slower in VMware server guests, but that's the case for every guest OS > - Would VMware server 1.0.2 cause many emulation problems running 32bit > or 64bit on single or dual core? No, just the annoying i386/SMP bug. Uwe
