Mmm... weird that you needed VirtPreview to get libvirt+xend to work. It
used, should, and actually does work for me on a "plain" F18 (i.e., no
VirtPreview).

Don't know why, but without the VirtPreview repo I get the following error:

"libvirtError: POST operation failed: xend_post: error from xen daemon: (xend.err 'Device 768 (vbd) could not be connected. Hotplug scripts not working.')"

What problem? Can you be more specific? Again, with xend, I don't have
problem of an kind, not even with virt-viewer.

If I run

$ virt-viewer rubis-web

where "rubis-web" is the name of my domU

I get a dialog box with this error message

"Unable to connect to libvirt with URI [none] "

and on the console terminal I get this message

** (virt-viewer:4506): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-giWEeisA4Z: Connection refused

(but I don't know if they are related, because the above message is only a warning, while the former is an error.)

Instead, if I use a VNC viewer (actually, tigervnc) it works without problems:

$ vncviewer 127.0.0.1:5900

If I look in the XML of my domU:

$ virsh dumpxml rubis-web

I can see the entry for VNC:

...
<graphics type='vnc' port='5900' autoport='yes' keymap='en-us'/>
...

Mmm... I might be wrong, but I'm not sure that's ever going to happen.
My understanding is that VirtPreview hosts the packages that are in
rawhide, although built for F18 (in this case). This means that most of
what you see there will end up in F19, and very few of it will involve
F18. However, if you find and rise a bug, unless the backport to the
libvirt version that ships with F18 is impossible, it shouldn't be a big
deal to have it fixed there too...

I see

Thanks for sharing your experience.

Dario

Thank you for the feedback!
