I'm in no way a performance expert, so I can't comment on most of the points you raise; hopefully someone with more experience in the area will be able to help you. That said...

I don't see why this would be a problem: installing VirtIO drivers in a guest is not unlike installing drivers that are tailored to the specific GPU in your laptop rather than relying on the generic VGA drivers shipped with the OS. Different hardware, different drivers. Moreover, recent Windows versions ship Enlightened I/O drivers which AFAIK do for guests running on Hyper-V pretty much what VirtIO drivers do for those running on QEMU/KVM. -- Andrea Bolognani / Red Hat / Virtualization _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
