This is just a general problem with virsh edit: it doesn't validate the XML, and it doesn't offer to re-edit invalid changes. Thus whenever you make a mistake in the XML it gets dropped. For more info and a proposed fix see this thread: https://www.redhat.com/archives/libvir-list/2011-August/thread.html#00660 To workaround this, do it the old way: virsh dumpxml HMC > hmc.xml edit hmc.xml virsh define hmc.xml iterate edit/virsh define steps until you get it right Which version of libvirt? According to the documentation <sysinfo> was added in 0.8.7. The fragment below looks reasonable, but there could be an XML error in the context of the whole XML document. > <sysinfo type='smbios'> > <bios> > <entry name='vendor'>xxx xxx</entry> > <entry name='version'>xxx</entry> > </bios> > <system> > <entry name='product'>xxx</entry> > <entry name='version'>xxx</entry> > <entry name='manufacturer'>xxx xxx</entry> > </system> > </sysinfo> > <os> > <type arch='x86_64' machine='pc-0.12'>hvm</type> > <boot dev='cdrom'/> > <smbios mode='sysinfo'/> > </os> Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.
