Hi,
the change-log for kvm-59 listed wide-screen-support. I found resolution
like 1680x1050, but the resolution 1280x800 for my 12-sub-notebook is
missing. It would be nice, if you add this resolution.
Sure thing, will be in kvm-60.

This adds a mechanism for exposing the virtual apic tpr to the guest, and a

Since gfn_to_page() is a sleeping function, and we want to make the core mmu

I plug an usb device with usb enabled it is getting terrible slow. I
