You can use virt-manager either from the Dom0 server (if it has all the<br>
GUI stuff and virt-manger installed) ... OR ... by connecting to the<br>
Dom0 using virt-manager from a Linux workstation. See my xen4centos<br>
libvirt article here:<br>

<a href="http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt">http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt</a><br>
<br>
You can also use Xen XM tools with the default install ... OR ... if you<br>
do not plan on using libvirt at all, you can setup and use Xen XL tools<br>
(if using libvirt, you have to use xend and Xen XM):<br>
<br>
XM Tools:<br>

XL Tools:<br>

Heaven help me, but I agree with you :)<br>
<br>
Libvirt and virt-manager is much easier to use than the command line<br>
tools ... although it also limits what you can accomplish as it only<br>
does a fraction of the possible configurations.<br>

IIRC I have used libvirt with the libxl driver (no xend running) and<br>
it seemed to work fine (although I was just learning and not really<br>
using it in production). Is there a reason you say you have to use<br>
xend rather than libxl with libvirt?<br>

Yes, there are (or at least were in xen-4.2.2, kernel-3.4.x, and<br>
libvirt-0.10.2.4 when we did extensive testing) some issues creating VMs<br>
using xenlight (XL) with the xen4centos libvirt.<br>
<br>
We have done many updates since then (much newer libvirt (0.10.2.8) and<br>
also 4.2.3 xen and even a newer kernel (3.10.x)) ... so it XL might work<br>
better now than it did initially.<br>
<br>
I would be glad to hear reports from others who have tested XL with the<br>
latest packages.<br>
<br>
You can not swap xen types on a dom0 ... SO ... do not break you<br>
production machines trying to go from XM to XL and vice-versa :)<br>

I'm looking forward to the page on libvirt bridging mentioned there.<br>
