I have 32bit FC7 installed and I replaced the hypervisor (xen.gz) with its 64bit version by extracting the RPM in order to allow me to see my 28GB of ram. Everything works fine and I can install both 32bit and 64bit FC7's paravirtualized. However, when I try to install (32bit) FC5/6 or Centos4/5 paravirtualized, it will not work. The VNC windows doesn't pop up and I notice the guest shuts down. They work fine if installed as fully virtualized guests as they should. Anything I need to do to make paravirtualized work with these Distro's? Thanks to everyone whos been helping this Xen beginner along. On a side note, when I tried installing FreeBSD 6.2 fully virtualized, it also didn't work. When I tried installing Debian, the install booted fine and I was setting up the install when virtmanager complained about something saying the install didn't work (even though it was running fine) and closed/deleted the VM.
