Yes, 
 virsh dumpxml NAME > NAME.xml; vi NAME.xml; virsh define NAME.xml
but there is no vfb line.

= fc6 domU =
On F7 dom0 if I do a fc6 domU install without a kickstart it begins in my terminal window, throws up a graphical console window if I've done xhost + dom0_server etc. This serial console window just has a dozen lines ending with a memory count. Then back in my terminal the typical anaconda installer shows up and all is fine.

= f7 domU =
If I do a f7 domU install without a kickstart it does something similar. 

virt-install --name=f7-inter --ram=1024 \
 --file=/var/lib/xen/images/f7-inter.xen \
 --file-size=10 --nographics \
 --location=http://ks/fedora/linux/releases/7/Fedora/x86_64/os \
 --extra-args='dhcp nofb' \
 --bridge=br101 --mac=AA:00:46:8D:7F:C8 --debug

It throws up the graphical serial console app but this window contains many more lines and the terminal never fires up anaconda. I tried adding nofb, selinux=0, and noacpi to the extra args. That didn't help.

Again, with kickstart it works eventually, but I don't see anything happening.
