This is a subtest in kvm. It will verify newly added pci block device now. For Windows support,it needs to use_telnet since 'wmic' which is used to check disk info could only be executed in telnet session not ssh. Just ran it on guest Fedora-11.32 and Windows2008.32, both passed:

- Can you add virtio-net and virtio-blk to Windows 2008 as well?
- Where are you formating the disk on Windows?
- You need to check in virtio-net - that the adapter can send/receive
traffic after hot-plugging; in virtio-blk - that you can read from /
write to the disk.
Thanks,
Y.
