xen "broke" my system
by Carlos Felipe Santacruz
This is what happened: normally ran 'yum install xen' and that gave
no problems, but then i rebooted to get to the xen kernel, it resulted
on black screen (could change consoles with Alt + F2 etc.) so i
rebooted and tried the regular 3.1.2 kernel with same results.
uninstalled xen with 'yum history undo' so it would also remove all
dependencies then rebooted. nothing.
anyone knows what could have caused this?
im running f16 x86_64 on an asus g74sx-bbk7(core i7-2630qm, geforce gtx560m, 8GB DDR3 ram)

Installing Fedora 16 in Xen PV DomU under Debian Squeeze
by David Howland
Hi, I recently installed Fedora 16 in a Xen PV DomU and since I didn't
find a lot of information online, I wanted to share my procedure in case
it helps anyone else. My Dom0 is Debian Squeeze, which uses a kernel at
version 2.6.32.
Because I deal with varying operating systems and because I prefer
fine-grained control over configuration, I don't use virt-* tools or GUI
front ends. I wanted to install the OS the regular way.
The basic install path was to use the live DVD to install in an HVM,
then switch to a PV with pygrub. I want to use pygrub so that I don't
have to copy kernels and init images around everytime the OS updates itself.
pygrub caused me some trouble because the version in my system can't
handle GPT partitions, grub2, or ext4 - all of which are used by default
in Fedora 16.
What follows isn't perfect, but should be useful for people who want to
install Fedora 16 in an environment similar to mine. Note that I'm
using x86_64 with VT-x, and that matters. Use your brain, and be
careful to recognize newlines that email may introduce.
