I believe this is the case. The time on the domain continues to increase.
However, with extra = "4 xencons=tty", I now get the last line to be
"Setting system clock" after I get "Couldnt get a file descriptor
referring to the console", 6 times.
So - it seems to be running, but I can't get a console to fix the
networking. So this approach seems not to work for me.

Is this done in menu.lst/grub command line?

Why isn't this generating lots of "I can't make a domU" posts? Is this
not an error everyone experiences?
