FC6 Xen - no luck here
I first installed Fedora Core 6 in a Parallels Virtual Machine. That was fine, but I quickly realized that I wanted to investigate this more deeply, and especially wanted to look at the Xen integration.
So, I created CD's and did the install on "Trusty Old Spare". That's been various machines over the years; whatever it is, it's the box I'm not currently using for anything else. Right now, it's a Dell OptiPlex SX270 P4 2.26GHz , which certainly ought to be current enough to play with Xen on FC6.
Yeah.. well, yes, but.. things didn't go so well. The very first thing to understand is that the Xen enabled kernel doesn't boot by default. You need to either edit your /etc/grub.conf or do Ctrl-X when you first see the flash screen and select the fc6xen kernel.
The second thing is that the virtualization software is not installed at all by default.
As you know, Fedora Core is shipped with X.Org v. 7.1, and therefore with AIGLX. And Compiz works fine.
However, there is not only Compiz, there is Beryl as well, and it is interesting because it comes along with such nice stuff as a Effects Manager and a Manager for the current system setup.
