Greetings, Luc,

Two things:

1) Your dom0 F7 machine can't be runing Selinux in Enforcing mode.
There's a denial related to udevd trying to load a kernel module that's
a problem. You can confirm this by looking for avc messages in
/var/log/messages if you don't have auditd loaded, or
/var/log/audit/audit.log if you do. I reported this problem to the
Selinux people so they're aware of it. Edit /etc/selinux/conf and set
SELINUX to permissive.

2) Your guest may very well be running, despite the nographics setting.
If you have a head on your dom0 machine, try turning on the --vnc option
and see what happens. If your dom0 is headless, redirect any X output to
some other machine that has a head (set DISPLAY, xhost, etc). Run your
virt-install, and see if the graphical console of your guest pops up. It
did for me, even though I didn't expect it to. Turns out that when
booting, the F7 guest console output starts on on the serial line, and
finishes up with the graphical console. I posted what to do about this
to Fedora-xen a week or so ago, so check the archives.

Good luck,

Mike
