Nice! However unless somebody else comes along and has the same expectations that I had (i.e. libvirt recognizing Xen guests with little or no configuration), I wouldn't put any effort into this. >> After correcting the domain XML, and restarting libvirtd once more, >> things start progressing: >> >> # virsh -c xen:/// list --all >> Id Name State >> ---------------------------------------------------- >> - host1 shut off >> >> … however “shut off” is incorrect. > > Stupid question but did you start the domain via virsh beforehand?

Not stupid because that's part of the point I've subtly been trying to make - I'm sticking with domU's started by /etc/init.d/xendomains and /usr/sbin/xl, the "Xen way". For four years during squeeze and wheezy, I had dropped in munin-libvirt-plugins and libvirt-bin (0.8.3 and 0.9.12) for the sole purpose of monitoring the domU's memory/cpu/io. This worked without any configuration other than specifying "uri xen:///" in the munin-node plugin configuration. During the "heartbleed" panic, after hastily reacting to the output of checkrestart, I accidently discovered that "service libvirt-guests restart" actually handles restarts of these "unmanaged" domU's. Fantastic! Consequently I've been telling sysadmin colleagues that libvirt is great because it integrates non-intrusively and can handle heterogeneous VM environments. Sorry - I was too quick to react after upgrading to jessie and opening this bug. FWICT libvirt+Xen/xl no longer supports this "unmanaged" use-case like the way libvirt+Xen/xend was able to in previous releases. In the meantime I've dropped in a non-Debian-packaged Xen munin plugin¹ and have stopped relying on libvirt. Perhaps one day I'll experiment with a managed libvirt+Xen setup on a non-Production system and report some real bugs ;-) ¹ http://munin-monitoring.org/browser/munin-contrib/plugins/virtualization/xen-multi -- Gerald Turner <gtur...@unzane.com> Encrypted mail preferred!
