Hi,
When doing device assignment with qemu and kvm upstream, I met "error: requires KVM support".  
Please also refer to the bug in qemu bugzilla. 
https://bugs.launchpad.net/qemu/+bug/882358

qemu.git commit:8843cf40c0f482949e6ae9d0119e45d6b96fe890

I met the following error when doing device assignment with qemu in kvm host.
./x86_64-softmmu/qemu-system-x86_64 -smp 2 -m 1024 -device pci-assign,host=0e:00.0 -hda /root/rhel6u1.img
qemu-system-x86_64: -device pci-assign,host=0e:00.0: pci-assign: error: requires KVM support
qemu-system-x86_64: -device pci-assign,host=0e:00.0: Device 'pci-assign' could not be initialized

./x86_64-softmmu/qemu-system-x86_64 -device ? 2>&1 | grep -i pci-assign
name "pci-assign", bus PCI, desc "pass through host pci devices to the guest"

When configuring the qemu, it prints "KVM support yes". My qemu configuration log and compiling log are attached.

But commit edbb7c0d doesn't have this issue.

Best Regards,
     Yongjie Ren  (Jay)
