[Pkg-libvirt-maintainers] Bug#991564: libvirt-daemon: USB cdrom removable=on: drive property not set

[chriz]

Package: libvirt-daemon
Version: 7.0.0-3
Severity: normal
X-Debbugs-Cc: debian_bug at valaskjalf.eu

Dear Maintainer,

when trying to add a USB CDROM drive which is empty, the VM doesn't
start anymore.
This is regardless if the removable check is set or not.

Error starting domain: internal error: qemu unexpectedly closed the
monitor: 2021-07-27T16:55:41.147567Z qemu-system-aarch64: -device
usb-storage,bus=usb.0,port=1,id=usb-disk1,removable=on: drive property
not set

When adding an iso to the drive, the VM can normally be started.


I get this error from virt-manager, but when opening the configuration
with virsh, I can see the flag is properly added to the config:
        <disk type='file' device='cdrom'>
                <driver name='qemu' type='raw'/>
                <target dev='sdb' bus='usb' removable='on'/>
                <readonly/>
                <address type='usb' bus='0' port='1'/>
        </disk>
When unchecking the removable check, the config correctly shows
removable='off' accordingly.

I can't tell, when the bug appeared, because I have not been using a USB
cdrom so far.

virt-manager is from testing (version 1:3.2.0-3)
