Can you post also qrexec log (now in /var/log/messages) from netvm and some other VM?

Looks like the first /etc/init.d/ntpdate restart did not synced the time. Tested manually and it also sets correct exit code (!= 0 if failed). But the other thing is interesting:
qvm-sync-clock calls in netvm (in order):
- nm-online -x (to wait for the network)
- /etc/init.d/ntpdate restart (to sync time)
Here I see that NetworkManager is started by pm-scripts AFTER calling nm-online -x (which exists immediately when no NetworkManager is running). So the order of pm-scripts need to be fixed.

BTW have you some messages about time sync in /var/log/pm-suspend.log (dom0)?

It seems like the qvm-sync-clock (most likely run by a cron job) has desynced my time. After resume the time was correct, but a few moments later it got set incorrectly to roughly the time when the machine was suspended a few hours back.
It seems like the ntpdate in the netvm must have failed (e.g. due to networking problem), but the qvm-sync-clock script must have missed that, and used the incorrect time from the netvm anyway.
Here's a snippet of my messages log from Dom0:
Note how the time was correct, and then suddenly changed to 01:16:23. Later it was reverted back to the correct value after I manually run qvm-sync-clock...
Interestingly I made an experiment: 1) I disabled networking, and 2) run ntpdate restart in the netvm, and 3) checked the $?, thinking it might be 0, and so explaining this problem. But it was correctly set to 1, so this doesn't explain how qvm-sync-clock might got a wrong time from netvm...
