Package: qemu
Version: 1:5.2+dfsg-10

hi,

recently i migrated a windows virtual machine from debian buster to
debian bullseye. Libvirt configuration was exactly the same but the
booted windows system lost its network connectivity and also deactivated
a second attached virtual disk because of policy reasons.

The problem would have also appeared if i simply updated the host system
from buster to bullseye.  Chances are high that this also results in an
unbootable virtual machine.

Investigation has shown that the following commit in qemu causing the
issue is most likely:
 
 Commit af1b80ae56c9 ("i386/acpi: fix inconsistent QEMU/OVMF device paths")

i havent checked in detail but it seems likely debian ships a qemu
version with this change.
