Description Martin Pitt 2023-01-23 06:10:20 UTC
Description of problem: In recent Fedora (and also Arch Linux [1]) there is a regression with trying to insert/change a virtual CD-ROM medium.


Version-Release number of selected component (if applicable):

virt-install-4.1.0-1.fc37.noarch
libvirt-daemon-9.0.0-1.fc38.x86_64
qemu-system-x86-core-7.2.0-4.fc38.x86_64
kernel-core-6.2.0-0.rc4.20230118gitc1649ec55708.33.fc38.x86_64

How reproducible: Always


Steps to Reproduce:

systemctl start virtqemud virtnetworkd
virsh net-start default || true  # may already be running
touch /var/lib/libvirt/bogus.iso
virt-install --memory 50 --pxe --virt-type qemu --graphics none --os-variant alpinelinux3.8 --disk device=cdrom,bus=scsi --wait 0 --name test1
virt-xml test1 --edit target.dev=sda --disk source.file=/var/lib/libvirt/bogus.iso,type=file --update

Actual results: Last command fails with

ERROR    Error attempting device update: internal error: unable to execute QEMU command 'blockdev-remove-medium': Tray of device 'scsi0-0-0' is not open


Expected results: command succeeds, and turns the previous

    <disk type='file' device='cdrom'>
      <driver name='qemu'/>
      <target dev='sda' bus='scsi'/>
      <readonly/>
      <alias name='scsi0-0-0'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

into

    <disk type='file' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <source file='/var/lib/libvirt/bogus.iso' index='2'/>
      <backingStore/>
      <target dev='sda' bus='scsi'/>
      <readonly/>
      <alias name='scsi0-0-0'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

Additional info: This could very well be a regression in QEMU. If so, please reassign. Thanks!

libvirt bug. See https://bugzilla.redhat.com/show_bug.cgi?id=2166411#c1

Comment 2 Ben Cotton 2023-02-07 15:06:13 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle.
Changing version to 38.

Comment 3 Martin Pitt 2023-04-30 07:50:47 UTC
Note that while this is fixed in RHEL/CentOS Stream 9, and does not happen in Fedora 37, this still affects Fedora 38 [1]. can you please apply the fix there as well?
