Hmm, that node is actually strange - I fixed this problem [1] and as long
as you have your 4.4 Node on latest packages (i.e., qemu-server in version
4.0-111 or newer) you should not run into this at all.

I'll update this section, thanks for noticing!

kernel upgrades and specific SW/HW setups - sadly.
