Hi!
Thanks for the report.
Could you post here the return of the command: xl info threads_per_core
on your host where you encountered the issue please?
Thanks
from xen-orchestra.
After force restart all works fine. So far I've installed latest XCP-NG updates on two hosts with same result - unable to perform smart reboot, access console of the VMs or stop VMs.
Here is the result after force restart.
from xen-orchestra.
When you say all works fine, does this mean that smart reboot as well?
If you still have an host you have not force rebooted yet can you try the same command on this host?
from xen-orchestra.
Yes, after force restart smart reboot works again. What I've also noticed that after installing those XCP-NG updates (beside issues mentioned above), RAM showed full use (0% free) and Hyperthreading as disabled.
I still have two hosts to upgrade but can't do that before 8PM (CET)
from xen-orchestra.
Okay so when you do, please before force rebooting run:
xl info threads_per_core
and
xe host-call-plugin host-uuid=<uuid of your host> plugin=hyperthreading.py fun=get_hyperthreading
and post the results here.
Latest changes bump the Xen version of XCP-ng and I suspect there's something there that perturbate xl info
or something, that is fixed after a reboot.
I'll look into it meanwhile.
Thx!

Perfect! Thank you for the info.
As I suspected something is wrong at Xen level after the upgrade.
Fortunately a force reboot solves everything.
I'll talk to this with the team.

This issue should not impact Smart Reboot, can you show me a log related to this problem?
