When "Microsoft Windows 7/2008" profile is selected on OS tab during VM creation, then qemu will be invoked with options -cpu kvm64,hv_spinlocks=0xffff,hv_relaxed,+lahf_lm,+x2apic,+sep -global kvm-pit.lost_tick_policy=discard, so when VM is started Windows dies with bsod code 0x5d (Unsupported processor). But when CPU is set to `host' it works as it should. May be this problem should be listed in wiki.
 
works here.

what is your host kernel ?

#uname -a

?

(and what is the windows version in your vm ?)
 
what is your host kernel ?
2.6.32-29-pve
(and what is the windows version in your vm ?)
2008R2 Standart Actually, on proxmox it dies even with CPU set to `host', i can't notice actual bsod code cause VM reboots immediately. I was experimenting on my Debian Wheezy desktop with QEMU 2.0 taken from backports to find solution. CPU on proxmox: cpu family : 6 model : 58 model name : Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz stepping : 9
 
I have several Windows Systems as VM in PVE, all are working very well with CPU set to `host'.

Do you turn off completely the VM after each change for that the changes take effect?
And tried to use cpu "qemu64"?

I'm sorry, but it was not a Proxmox issue, it was issue with OS inside VM. Clean Win2k8r2 runs as it should.

Do you known exactly what was the problem ?
proxmox use hyperv optimizations, so maybe windows was not updated ?
 
There was a OS loader installed inside to "activate" system. It was causing problems.
