Yes, this is a bug. > - When I tried to access it via ssh, it did not accept the root password that > virt-builder had displayed before exiting.

[...] I was able to reproduce this myself: $ virt-builder ubuntu-16.04 --firstboot-command "dpkg-reconfigure openssh-server" --root-password password:123456 $ qemu-system-x86_64 -nodefconfig -display none -machine accel=kvm:tcg -m 2048 -boot c -drive file=ubuntu-16.04.img,format=raw,if=ide -netdev user,id=usernet,hostfwd=tcp:127.0.0.1:9000-:22 -device rtl8139,netdev=usernet -serial stdio Observe that it boots without any console output. In another window, try: $ ssh -v root@localhost -p 9000 SSH will hang during connection. If you repeat the same tests as above, but using fedora-24, it works fine. By looking at the Ubuntu disk image directly, I was able to see that: - it boots - it runs the firstboot command, successfully - the ssh server does not see any connections - it is unclear if the root password is being set correctly or not, because we never actually test that So this Ubuntu template is all-round buggy, and possibly or possibly not there is another bug with setting passwords (only affecting Ubuntu). Noted, and I'll try to have a look at this soon. Also we don't regression test any of this (for any guest), which is another bug.
