Hello Eric, thank you for your answer; I had hoped to stop your from spending any further time ony this by my 2nd mail from October 26, because I found my thinko myself after reading some more code. Actually I was reading a patched version, where the patch broke it. > > This behaviour is actually documented in > > <http://libvirt.org/html/libvirt-libvirt.html#virDomainUndefineFlags> > > (now that I know what I have to look at), but I was still surprised that > > virDomainUndefineFlags(0) returned success on my inactive domain with > > snapshots. > > That shouldn't happen - virDomainUndefineFlags(0) on an inactive domain > should fail if the domain has snapshots. Is this something you actually > hit, and can you give me steps to reproduce? The patch tried to work around the case of migrating VMs with snapshots, which is (as far as I know) still not possible, because there is no way to migrate the unknown size of snapshot xml data. Our current workaround is to put /var/lib/libvirt/qemu/snapshot/ on a NFS and to patch libvirt not to delete the snapshot XML data von migrate --undefinesource. So thanks again for spending your time; your mail was still much appreciated.
