Before:
$ uname -m
s390x
$ cat passthrough-cpu.xml
<cpu check="none" mode="host-passthrough" />
$ virsh hypervisor-cpu-compare passthrough-cpu.xml
error: Failed to compare hypervisor CPU with passthrough-cpu.xml
error: internal error: unable to execute QEMU command 'query-cpu-model-comp
arison': Invalid parameter type for 'modelb.name', expected: string
After:
$ virsh hypervisor-cpu-compare passthrough-cpu.xml
CPU described in passthrough-cpu.xml is identical to the CPU provided by hy
pervisor on the host
