Package: libvirt-daemon-driver-lxc
Version: 7.0.0-3
Severity: normal
Dear Maintainer,
A Debian 11 RC2 container running on a Debian 11 RC2 hosts responds
to the reboot command by shutting down services and then powering
off, *not* by rebooting, which is what I would expect.
This applies regardless of whether I:
* run 'reboot' inside the container
* run 'virsh reboot' on the host
* run 'kill -SIGINT 1' inside the container
This is consistently reproducible.
Here's output from trying it with 'virsh reboot', as it's the
most copy-and-paste-able:
pestaroli# export LIBVIRT_DEFAULT_URI=lxc:///
pestaroli# virsh list --all
Id Name State
--------------------------
- mafalde shut off
pestaroli# virsh start mafalde
Domain 'mafalde' started
pestaroli# virsh list --all
Id Name State
-----------------------------
467946 mafalde running
pestaroli# virsh reboot mafalde
Domain 'mafalde' is being rebooted
pestaroli# virsh list --all
Id Name State
--------------------------
- mafalde shut off <-------------- should be 'running'!

I am submitting this bug report against the libvirt-daemon-driver-lxc
package because /usr/lib/libvirt/libvirt_lxc is the parent of the
container's init process:
root 468678 0.0 0.4 355008 17096 ? Sl 15:26 0:00
/usr/lib/libvirt/libvirt_lxc --name mafalde --console 30 --security=apparmor

but it might well be that the bug is in another package (I think
you are more qualified to judge that than I am), so please reassign
if you think appropriate. In case it is relevant, here are the
lxc/libvirt/systemd packages installed on the host:

For comparison:
A Debian 11 RC2 container running on a Debian 10.10 host responds
to the reboot command by shutting down services and then hangs
(I waited about 10 minutes) without turning off with the last message:
[ OK ] Reached target Reboot.

If you need more info or have packages you'd like me to test, then
just let me know.
Thanks for your support,
Alexis
PS standard '-- System Information' section of this reportbug-based
report deleted as it pertains to the host I am submitting the
report from, not the host on which the bug was seen.
