[Libguestfs] Virtio devices as removable?

Hello, Not sure if this is the correct list so apologies if this question is misplaced. I tried migrating using virt-v2v a pair of Windows 2012R2 servers to oVirt using Fedora22 as a p2v server and was happy to see that it worked perfectly. I notice however that the windows icon for "safe removal" now appears on the bottom right, and when I click it, apparently I can "safely remove" my VirtIO NIC, a VirtIO serial device, and my VirtIO disk!?!?!?! I tried it on the NIC as a test and unsurprisingly, I lost all network communication to the host. I didn't try it on the VirtIO disk because I didn't want to risk crashing my OS, however this doesn't seem normal. The disk on which the system is running can't be removable?! How can I fix this? Thanks, M.
