[libvirt-users] Revert to internal snapshot - XML error: Non-empty feature list specified without CPU model
Versions:
$ rpm -q libvirt-daemon-kvm qemu-system-x86
libvirt-daemon-kvm-1.2.9-3.fc21.x86_64
qemu-system-x86-2.1.2-4.fc21.x86_64
When I attempt to revert to an internal snapshot:
$ virsh snapshot-list node1
Name Creation Time State
------------------------------------------------------------
snap1 2014-06-03 14:07:28 -0400 running
$ virsh snapshot-revert node1 snap1
error: XML error: Non-empty feature list specified without CPU model
Contextual guest XML:
$ virsh dumpxml node1 | grep features -A3
<features>
<acpi/>
<apic/>
<pae/>
</features>
<cpu mode='host-passthrough'>
</cpu>
<clock offset='utc'>
I see it's thrown from here, src/conf/cpu_conf.c, from function:
virCPUDefParseXML:371
[. . .]
367 if (n > 0) {
368 if (!def->model && def->mode != VIR_CPU_MODE_HOST_MODEL) {
369 virReportError(VIR_ERR_XML_ERROR, "%s",
370 _("Non-empty feature list specified without
"
371 "CPU model"));
372 goto error;
373 }
[. . .]
I can manually revert this snapshot via `qemu-img`, but wondering if
this error from libvirt expected in this case?
