Virtual Server 2003 R2 SP1 and Windows 2003 SP2 (x64)
Watch out boys and girls looks like there’s a fault somewhere in SP2 that breaks something in VS system. We run a Windows 2003 Standard x64 server as a host with a number of different guest. One of the guest did have a COM port forwarded into and and we never had a problem. That is until we put Windows 2003 SP2 on everything. Then the vssrvc.exe would sit at 100% CPU even when the guest where doing jack !
Hours of fiddling found out that it was a COM port being forwarded into a guest. You could turn it off and back on again and watch the machine spazz out. And de-installing SP2 from the host did nothing to fix the problem. So we no longer send COM ports to the guests. Not sure if it’s just effecting x64.
Yes the Virtual Server 2003 R2 SP1 beta team have been told and no they haven’t acknowledged the fault yet (263691).
