Comment 11 for bug 1630909

Running with debug enabled shows that it actually runs fine until it tries to create a temp directory:

Something around systemd-coredump does not sound good.

autopkgtest-virt-qemu: DBG: execute-timeout: /tmp/autopkgtest-qemu.us495jpz/runcmd true
autopkgtest-virt-qemu: DBG: can connect to autopkgtest sh in VM
autopkgtest-virt-qemu: DBG: determine_normal_user: got user "systemd-coredump"
autopkgtest-virt-qemu: DBG: auxverb = ['/tmp/autopkgtest-qemu.us495jpz/runcmd'], downtmp = None
autopkgtest-virt-qemu: DBG: execute-timeout: /tmp/autopkgtest-qemu.us495jpz/runcmd mktemp --directory --tmpdir autopkgtest.XXXXXX

In this state I can't login anymore at all

I found a few processes like these:
$ /usr/bin/python3 /tmp/autopkgtest-qemu.us495jpz/runcmd mktemp --directory --tmpdir autopkgtest.XXXXXX
Which seem to be the host counterpart to the hanging guest processes I think.

This makes this even less working :-/
