Thanks for the notice. It doesn't look like the fix went in. See below:

# yum repolist | grep xen
centos-virt-xen-testing  CentOS-6 - xen - testing                            102
# rpm -qf /etc/xen/scripts/hotplugpath.sh
xen-runtime-4.6.1-9.el6.x86_64
# rpm -V xen-runtime

Confirmed installation of 4.6.1-9 from virt-xen-testing. Confirmed
files "as packaged".

# grep LOCK /etc/xen/scripts/hotplugpath.sh
XEN_LOCK_DIR="/var/lock"

The XEN_LOCK_DIR still points to the wrong directory.
Am I missing something?

Yes, you are missing someting. :-)  XEN_LOCK_DIR is used for a number
of different things; but *only* "I am alive" init script files should
live in /var/lock/subsys.  (Presumably that's why it's a separate
directory to begin with.)  So the "proper" fix is to have the
xendomains script check for the existence of $XEN_LOCK_DIR/subsys and
use it if available.  See my original patch submission for more
details [1].

So, I've tested the packages and they work for me, let me know if you
have any problems. :-)

Oh, good! Thanks for the explanation.

Updated to 4.6.1-9 testing, and things are looking good: in
particular, I confirm domUs were saved+restored on dom0 restart.

Thanks again,
