And now test the old vs the fixed wait script - example here is from
noble but it looks the same in all host releases. As mentioned the noble
vs plucky here is not host but guest release that we compare as that is
where the behavior changed.
1. check if guests are up and respond
paelzer@Keschdeichel 12:10:08 1 ~ uvt-kvm ssh n uptime
11:10:23 up 0 min, 1 user, load average: 0.92, 0.22, 0.07
paelzer@Keschdeichel 12:10:25 ~ uvt-kvm ssh p uptime
11:10:28 up 0 min, 2 users, load average: 0.85, 0.26, 0.09
2. check for the reported issue directly
paelzer@Keschdeichel 12:11:00 130 ~ uvt-kvm ssh n runlevel
N 5
paelzer@Keschdeichel 12:11:07 ~ uvt-kvm ssh p runlevel
unknown
=> we see that it never gets into a proper state
3. check how that translated into the hang in the wait script before the
fix
paelzer@Keschdeichel 12:11:10 1 ~ md5sum
/usr/share/uvtool/libvirt/remote-wait.sh
3bf4076b196e49e6cae83968d5b67cca /usr/share/uvtool/libvirt/remote-wait.sh
paelzer@Keschdeichel 12:11:50 ~ time uvt-kvm wait n
real 0m1,023s
user 0m0,571s
sys 0m0,120s
works for e.g. noble
Fails for plucky (I aborted it)
paelzer@Keschdeichel 12:11:54 ~ time uvt-kvm wait p

4. upgrade this machine as well to the new wait script
paelzer@Keschdeichel 12:12:40 ~ sudo apt install uvtool-libvirt -t

5. verify the new script works on old and new guests
Still working on noble guest
paelzer@Keschdeichel 12:13:19 ~ time uvt-kvm wait n
real 0m0,913s
user 0m0,537s
sys 0m0,117s
paelzer@Keschdeichel 12:13:54 ~ time uvt-kvm wait p
running
real 0m0,807s
user 0m0,513s
sys 0m0,090s
Works - setting verified for all releases that share the wait code.
