What's awkward about it?  When I've passed "serial=pty" in the
HVM
config file and run "xl console", everything seems to work pretty well
for me.

And playing with the grub settings. And making sure that the installer
correctly handles serial access, which tends to confuse the heck out
of anaconda, and has only gotten worse with the pointlessly and
insistently graphical installers in CentOS 7.

I'm not blaming the CentOS team, this came from Fedora upstream to RHEL.

Ah, right -- my primary hat is as Xen developer, so I thought you were
complaining about something on the xen side, not on the installer
side. :-)
