[PVE-User] Restoring Win2k8 R2 64bit to PVE 2.0 (-cpu host!)

[Hart, Brian R.]

Ok,

I figured out what the issue was from experimenting further.  In 1.9, I
specified args: -cpu host in the config file manually for these VMs as
they are doing some processor intensive tasks.  I had previously tried
disabling this in the GUI in 2.0 but because I had specified it by hand in
the conf file it was still in the conf file after restoring the system.

Basically, any Windows VM I try to use -cpu host with (even if I remove it
from the conf and add it through the web interface) the VM crashes with a
BSOD on startup.  If I change the cpu to qemu64, the default, it boots up
and works fine.

Anybody seen this before?

Thanks!
