[solved] Libvirt 2.2.0 - Windows 7 guest not starting with hypervclock

I'm trying to use new and shiny HyperV features of libvirt/qemu and the very first one stops Windows from booting. If set to "no", Windows boots just fine, if to "yes" - "Starting Windows" is displayed for a second, then guest screen goes black indefinitely.

virt-xml win7 --edit --clock hypervclock_present=yes

I tried setting <vendor_id state='on' value='HyperV123'/> and <kvm> <hidden state='on'/> </kvm>, but that didn't help any.
Any ideas?

Re: [solved] Libvirt 2.2.0 - Windows 7 guest not starting with hypervclock

Folks at qemu-devel mailing list pointed out that there's a bug in Windows 7 that does not allow UEFI (OVMF) + Windows 7 + HyperV features combination.
