It seems that virt-xml-validate doesn't validate what *has* to be valid XML, that generated by virsh dumpxml against a running domain: [root@etc752365a ~]# virsh list  Id Name                 State ----------------------------------  2 rhel55               running  3 rhel53               running [root@etc752365a ~]# virsh dumpxml rhel55 > foo.xml [root@etc752365a ~]# virt-xml-validate foo.xml foo.xml:8: element type: Relax-NG validity error : Invalid attribute arch for element type foo.xml:9: element boot: Relax-NG validity error : Element os failed to validate content foo.xml:8: element type: Relax-NG validity error : Error validating value foo.xml:8: element type: Relax-NG validity error : Element type failed to validate content foo.xml:1: element domain: Relax-NG validity error : Invalid sequence in interleave foo.xml:1: element domain: Relax-NG validity error : Element domain failed to validate content foo.xml fails to validate Is there something that I'm doing wrong here? This is the libvirt that comes with RHEL5.5

Maybe the >problem has already be fixed in a newer version. After opening a support case, they had me replace 'rhel5.4.0' in the type element with 'pc' and it seemed to work well. I've attached the XML at any rate.
