QUESTION: What, if anything, can I do so that I can use xl (in place of
xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
BACKGROUND: I am testing a fully updated (as of March 27) installation of
Ubuntu 13.04 that includes the following packages:
libvirt - version 1.0.2-0ubuntu9
xen-hypervisor-4.2-amd64 - version 4.2.1-0ubuntu1
Upon setting TOOLSTACK=xm in /etc/default/xen (as well as making a few
needed tweaks to /etc/xen/xend-config.sxp), libvirt and virt-manager worked
great. Yippee!
I guess that I should be happy that the xm toolstack still works with Xen
4.2.1 and quit while I'm ahead, but...
According to libvirt's documentation:
"libxl: Starting with Xen 4.2, the legacy XenD/xm toolstack is deprecated
in favor of libxl, also commonly called libxenlight. libvirt supports this
new Xen toolstack via the libxl driver. If XenD is enabled, the legacy xen
driver consisting of the above mentioned channels will be used. If XenD is
disabled, the libxl driver will be used."
See http://libvirt.org/drvxen.html.
In view of the above, I attempted to use xl in place xm by setting
TOOLSTACK=xl in /etc/default/xen. And after doing so (both with and
without, the above mentioned tweaks to /etc/xen/xend-config.sxp), I
recieved the following error when attempting to start virt-manager:
Unable to connect to libvirt.

New subject: [libvirt-users] [virt-tools-list] How to use xl (in place of xm) with libvirt 1.0.2 and Xen 4.2.1 in Ubuntu 13.04?
Hi Jim,
Thanks much for suggestions. And please accept my apologies for not
replying sooner. Your reply got buried in lots of other list-serve
messages.
You asked: "Ensure xend is *not* running and then restart libvirtd. The
libvirt libxl driver will only load when xend is not running."
I'm a bit new at this, but I was under the impression that setting setting
toolstack=xl in /etc/default/xen would prevent xend from starting. That
is, I thought that xend wouldn't start when xl was running. Am I totally
wrong about that?
In any case, xl is running and if I try to send an xm command, I get the
following: "A different toolstack (xl) has been selected!" Is there
something else that I should try to insure that xend isn't running?
(As a reminder, if I set toolstack=xm in /etc/default/xen, virt-manager
works great. But I'm hoping to use the xl toolstack.)
You asked: "Did the libxl driver even load? There should be some evidence
of that in libvirtd.log."
My libvirtd.log doesn't seem provide any evidence of that the libxl driver
is loaded. (See log copied below.) But libvirtd.log does mention an
"internal error failed to connect with xend." So honestly, I'm not quite
sure whether libxl loaded. What's the best way to confirm?
You asked: "Has your libvirt package been built with the libxl driver
enabled?"
I'm using the libvirt package that is available from the Ubuntu 13.04 (and
now 13.10) repository. How would I go about checking whether that package
was built with the libxl driver enabled?
Thanks so much for any additional help you can provide!
Best regards,
GizmoChicken

Not sure. I use fedora and openSUSE. I haven't used Ubuntu's virt

Jim,
Thanks so much for your help. Much appreciated!
I filed a bug report with Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1180281
Hopefully other Ubuntu users who are experiencing the same issue will add
comments/feedback to the bug report.
Best regards,
