Subject: libvirt-daemon-driver-lxc: container reboot done from inside or outside container shuts container down

Date: Sun, 01 Aug 2021 16:37:13 +0200

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'!
	
	pestaroli# 

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 --handshake 34 --veth vnet77
	100000    468681  0.7  0.2  99948 10008 ?        Ss   15:26   0:00  \_ /sbin/init
	100000    468713  0.3  0.3  31932 13016 ?        Ss   15:26   0:00      \_ /lib/systemd/systemd-journald
	100105    468770  0.1  0.1   7952  4332 ?        Ss   15:26   0:00      \_ /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation --syslog-only
	
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.

A Debian 10.10 container running on a Debian 10.10 hosts responds
to the reboot command by shutting down services and then hangs
(I waited about 10 minutes) without turning off with the last messages:

	[  OK  ] Reached target Reboot.
	logout

If you need more info or have packages you'd like me to test, then
just let me know. 

Thanks for your support,

Alexis
