For host-passthrough CPU we don't honor the CPU features specified in the XML, but we allow outputting them via the UPDATE_CPU flag for dumpxml, this gives user a rough idea of what features the CPU might have. After restoring a managedsave'd domain, the features might end up in the live status XML (in /var/run) without the model. This XML cannot be parsed by the daemon after restart and the domain might disappear. This fix skips formatting the features for HOST_PASSTHROUGH when UPDATE_CPU is not specified, so the newly restored domains and newly created snapshots won't be affected. Note: this doesn't fix existing snapshots or already restored running domains. https://bugzilla.redhat.com/show_bug.cgi?id=1030793 https://bugzilla.redhat.com/show_bug.cgi?id=1151885 --- src/conf/cpu_conf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/conf/cpu_conf.c b/src/conf/cpu_conf.c index 2650208..67203c6 100644 --- a/src/conf/cpu_conf.c +++ b/src/conf/cpu_conf.c @@ -658,7 +658,7 @@ virCPUDefFormatBuf(virBufferPtr buf, virBufferAddLit(buf, "/>\n"); } - for (i = 0; i < def->nfeatures; i++) { + for (i = 0; formatModel && i < def->nfeatures; i++) { virCPUFeatureDefPtr feature = def->features + i; if (!feature->name) { -- 2.0.4 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
