    conf: fix parsing of NUMA settings in VM status XML
    Commit 5bba61f changed the XPath strings to be absolute when parsing
    the VM NUMA configuration. Unfortunately the <domain> element is not a
    top level element when parsing the domain status XML thus the absolute
    XPath string doesn't match.
    Use the relative string so that the <numa> settings are not lost.

Can not reproduce this issue with libvirt-1.2.8-16.el7_1.2 and libvirt-1.2.8-16.el7, so set regression keyword

Comment 3 Jiri Denemark 2015-04-01 06:33:15 UTC
Fixed upstream by v1.2.13-272-gd75e23b
