I have been trying all day to reuse a Windows 2012 virtual hard drive from my Centos 6.4 KVM Host and I keep getting a crash on start.
Finally, I remember that a few weeks ago I opened a bug with redhat
https://bugzilla.redhat.com/show_bug.cgi?id=821741 . This is the same bug and it means that Proxmox 3.0 is trying by default to create a 32 Bit Virtual machine, and KVM crashes instantly with Windows 8 in 32 bits. So the question is, how do I force Proxmox to start always a 64 bit virtual machine environment, and never a 32 bit one. In a 64 bit environment I can install any 32 bit OS. An additional piece of information, the virtual hard disk is *.qcow2 and it resides in an NFS mount.

few week (3.1). As workaround, you can add the following in your vm config file:

args: -cpu kvm64,+sep
 
I did add the line, and it still crashes.
Any ideas?
I can give you direct access to the box.
The fact that this works fine in Red Hat 6.4 shows that the issue is in Proxmox. I mean, a 64 bit virtual machine should not be affected by this bug.
Or maybe I am misunderstanding the issue.
Thanks in advance.
