182 fails if qemu has no support for hotplugging of a virtio-blk device.
Using an NBD server instead works just as well for the test, even on
qemus without hotplugging support.

Hmm, just seeing this after I already sent a pull request doing the same through NBD. Git should handle things correctly, whether or not you rebase to drop patches from your block branch that get in through my NBD pull request. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
