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.
