I have also installed the GPLPV drivers. But they didn't help with

Well the W2K3 seems to work without problems. Although those virtual 
machines only use one CPU so can't know for sure.

Memory use really isn't problem. But the issue still remains that I 
would need some way to get Windows 2008 to relax the timing requirements 
for the CPU's. So that it wouldn't do the BSOD's on the missed clock 
interrupts. And don't want to go back to 2003 as these machines will 
most probably be running next 5-years with this os.
