Hi Chris, I tested this issue on Windows 7, 10 and Ubuntu 15.10 hosts, NAT and bridge networking using virtio-net adapter. I think guest configuration is also important. Do you have any CIFS/NFS/etc shares mounted in the guest? Sounds like 'Unable to mount/umount root fs' and networking could be the key.
