[Pkg-libvirt-maintainers] Bug#911369: libvirt0: Virtual machines no longer see storage / network devices

[Elena ``of Valhalla'']

Package: libvirt0
Version: 4.7.0-1+b1
Severity: important

Dear Maintainer,

after a kernel update (4.18.10-1 -> 4.18.10-2) the machines I created
with virt-manager and QEMU/KVM are no longer able to boot because they
can't find /dev/vda1.

I played around with other storage buses (e.g. SCSI), to no avail.

I then tried to create a new machine from scratch with the stretch
netinstall and discovered it wasn't able to find any ethernet device.

Rebooting the host with the previous kernel resulted in the virtual
machines correctly working.

Please, let me know if I have to try something else to help you
reproduce the bug
