I don't think this issue has anything to do with PVHVM.

The "-c" option here asks to connect to the domains serial console,
which you haven't configured, so it fails.

Either omit the "-c" and use SDL or VNC to get to the VGA console or add
    serial = 'pty'
to your guest configuration, which should make "-c" work as expected.
Unless the CentOS installer launches on the serial console you are
probably better off going the VGA route.

These are harmless (if annoying...)

Anyone can edit the wiki, simply sign up for the wiki by clicking on the
link in the banner at wiki.xen.org and then fill in
 (which is needed because of an ongoing spam attack).

I would encourage you where possible to try and improve existing
documentation rather than adding another walk through.
