Re: KVM libvirt issue on Debian Wheezy specifically Windows 7 64bit

just adding some more info.

I have been using Proxmox 3.x for quite some time on the same hardware but for some learning purpose i installed libvirt and virt-manager.

Proxmox also based on same KVM engine and Debian destro and my windows 7 64 bit is working great even i have installed Server 2012 in proxmox with no issue on same hardware with VT ON.

therefore it seems to me the limitation or problem is not the hardware. it is something in the software.

moreover i have installed Windows XP 32 bit. on the said debian Guest with KVM+libvirt which is working fine on any version combination of libvirt and KVM. only thing which is not working is higher version of windows such as windows 7 and server 2008. i never tried vista though.

Any information or help will be highly appreciated.

Thanks,

Yousuf
