[Pkg-libvirt-maintainers] Bug#954291: libvirt-daemon-system-sysv: upgrading kills VMs

[Thorsten Glaser]

Package: libvirt-daemon-system-sysv
Version: 6.0.0-3
Severity: critical
Justification: causes serious data loss

Just a regular dist-upgrade doing this:


Unpacking libvirt-daemon-system-sysv (6.0.0-3) over (6.0.0-1) ...
[…]
Setting up libvirt-daemon-system-sysv (6.0.0-3) ...
Restarting libvirt logging daemon: /usr/sbin/virtlogd.
Restarting libvirt management daemon: /usr/sbin/libvirtd.

Running guests on default URI: MirBSD
Shutting down guests on default URI...
Starting shutdown on guest: MirBSD
Waiting for guest MirBSD to shut down, 300 seconds left
[…]


It’s inacceptable for a regular package upgrade to shut down
any running VMs without warning. The VMs may be necessary, or
might need to be shut down manually (qemu’s guest agent still
doesn’t work without native virtio in the guest even though a
serial (IIRC) control channel is specified), and killing such
a VM will introduce guest filesystem corruption.

At least issue a debconf thing like glibc does when you want
to upgrade from 2.29 to 2.30, which offers me some time to
shut down the VM manually or abort the upgrade.


To add insult to injury, it didn’t even shut it down cleanly:

tglase at tglase:~ $ virsh -c qemu:///system list
 Id   Name     State
----------------------------
 3    MirBSD   in shutdown


“virsh destroy 3” to the “rescue”…
