There are a few subdirectories under /etc/libvirt and /var/lib/libvirt that can be shared (in fact, http://libvirt.org/locking.html documents that /var/lib/libvirt/sanlock must be shared to be useful), but these are the exception, not the rule. Correct - libvirt will not follow symlinks when saving internal configuration, but rewrites the file from scratch without preserving the symlink. And I don't think this is a bug, since we already explicitly document that files under /etc/libvirt are internal to libvirt, and must not be shared. Rather, it is probably an intentional side-effect of a recent libvirt change to atomically update internal .xml files (libvirt used to write over internal files in a non-atomic manner, which could corrupt domains if a power outage occurred at the wrong moment). If you want to store your configuration in shared storage, then the only supported method of doing that is to store the XML independently of /etc/libvirt. For example, you can 'virsh dumpxml $dom > /mount/$dom.xml' to save off the configuration to shared storage, and 'virsh define /mount/$dom.xml' to reload the shared configuration if you don't trust what might be in place locally. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
