No mystery. Libvirt Xen driver was broken already on Ubuntu 8.04 (
Hardy Heron) Server
and never fixed afterwards.
Boris.
P.S. View Ubuntu's Launchpad
I checked the ubuntu launchpad but it only lists 6 bugs for 'libvirt
xen' search:
https://bugs.launchpad.net/ubuntu/+bugs?field.searchtext=libvirt+xen&orderby=-importance&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=
I didn't see any mention of this specific connection error. Is there
another bug somewhere about this problem?

Ok, found a couple things. xend-http-server was not enabled in
/etc/xen/xend-config.sxp.
So then I try to restart xend and found that no matter what I try to
do with xend it just hangs the terminal; start, status, reload all
hang. So this I don't understand.
# ps -ef | grep -i xen
root 23 2 0 16:38 ? 00:00:00 [xenwatch]
root 24 2 0 16:38 ? 00:00:00 [xenbus]
root 1901 1 0 16:38 ? 00:00:00 xenstored --pid-file
/var/run/xenstore.pid
root 1905 1 0 16:38 ? 00:00:00 /usr/bin/python2.6
/usr/sbin/xend start
root 1908 1 0 16:38 ? 00:00:00 xenconsoled
root 1910 1905 0 16:38 ? 00:00:01 /usr/bin/python2.6
/usr/sbin/xend start
It looks like it's running though but you cannot control it with the
init.d script.
What I did find is that after enabling the xend-http-server and then
rebooting the host that I could connect to the xen hypervisor:
root@grp-01-23-02:~# virsh -c xen:/// list
Connecting to uri: xen:///
Id Name State
----------------------------------
0 Domain-0 running
root@grp-01-23-02:~# virsh list
Connecting to uri: qemu:///system
Id Name State
----------------------------------
qemu/kvm is still the default hypervisor.
So now one last thing I need: how to set xen as the default hypervisor
for libvirt.
-Gerry
VIRSH_DEFAULT_CONNECT_URI="xen:///" seems to do the trick. Virsh is
able to create and shutdown the Xen domain and report stats so
everything looks good.
