FTR previously libvirt was accepting this action and XML it generated was: <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native' iothread='2'/> <source dev='/dev/dm-58' index='4'/> <backingStore/> <target dev='vdc' bus='virtio'/> <serial>05fcc448-4775-4692-9c22-f931d3356ca1</serial> <alias name='virtio-disk2'/> <address type='pci' domain='0x0000' bus='0x08' slot='0x00' function='0x0'/> </disk> This has been introduced by a following commit (reverting fixes the problem): commit 3df66f27a606c5c0f27958edf7bfaaf7dcc71264 Author: Peter Krempa <pkrempa> Date: Fri Apr 30 16:19:15 2021 +0200 qemu: Move iothread and s390 address validation for disk devices into the validator The "machine-loadparm-multiple-disks-nets-s390" case now requires the QEMU_CAPS_CCW feature to pass validation. Signed-off-by: Peter Krempa <pkrempa> Reviewed-by: Ján Tomko <jtomko> Reviewed-by: Pavel Hrdina <phrdina> Fixed upstream: commit c29bb0fbb623af7994925bccad04060c5e27b64b Author: Peter Krempa <pkrempa> Date: Thu Jun 10 16:43:36 2021 +0200 qemu: validate: Don't check bus type in qemuValidateDomainDeviceDefDiskIOThreads IOThreads are supported with all 3 currently supported buses which can have virtio devices (PCI, CCW, MMIO) , so there's no need for this check. Additionally this check was buggy in the current location as on e.g. hotplug cases the address may not yet be assigned for the disk and thus a bogus error would be printed.
