Any commonly available upstream Xen releases.
Fedora itself
(ie. https://fedoraproject.org/wiki/Features/XenPvopsDom0).
Also Xen in RHEL 5, although that's more of a thing for Red Hat to
worry about.

Yes.

Product: Fedora. Component: depends on what is failing but common
ones would be "kernel", "anaconda", "grubby", "grub2", "xen", and
"libvirt".
There is also a Fedora Xen mailing list where you can get more
detailed help:

libvirt support for xm/xend *should* work, and there's also the libvirt libxl driver
written by Jim Fehlig from Novell/SUSE.

When you install libvirt it'll automatically create/start a bridge called "virbr0",
which is an host-internal bridge with "dnsmasq" running and configured to provide dhcp server
with private ip range, dns relay and NAT on that bridge.
So that's good enough for trying some VMs or running VM netboot installs.

Luckily Xen Hackathon (@Munich) event is just happening,
so hopefully we can get some more testing from people in that event.

I just added some Xen related mailinglists to the CC list,
so we can get more feedback.

150 second timeout
by Jerry James
I have a Fedora 15 x86_64 system, 8 GB of RAM, 4 CPUs, 1 terabyte
disk. I run several virtual machines on it, used to check
cross-system compatibility of some software I develop for my employer.
I run "yum upgrade" on the host every work day, so it is up to date
as of today (August 31).
I have a RHEL 6.1 guest that I am using very heavily right now. I run
it with virt-manager. The guest's disk is a logical volume with no
(host) filesystem. The guest's memory is drawn from a 1 GB hugetlbfs.
The host has a Nehalem CPU, which is exposed (to the extent possible)
to the guest. The display uses spice + qxl drivers in the guest.
Recently, the guest has gotten stuck from time to time. I'll be
typing away and suddenly the guest's display will freeze. When this
happens, I can still use the mouse to perform functions on the host,
but pressing keys has no effect. Exactly 150 seconds later, the guest
will unfreeze (sort of; see below) and I can change keyboard focus to
other host applications again. At that point, the guest window will
*partially* repaint, but will still not change in response to mouse or
keyboard actions. I have to close that window and then click in
virt-manager to open a new window. At that point, I can see that all
of the key presses I made while it was frozen were received and acted
on by the guest, so it is only the display that froze.
I have other Linux guests. None of them display this behavior. Is
this some kind of incompatibility between the RHEL 6.1 qxl drivers and
Fedora 15 spice? Does a 150 second timeout ring a bell with anyone?
Is there some way to get the keyboard focus away from the guest when
this happens so I can at least do something useful on the host?
Thanks,

CD-ROM Puzzle
by Ken Smith
Hi Folks,
Been using KVM on Fedora 13/14 for a while now.
I have set up a FC14 machine with 2 linux and one windows guest. I'm
finding that I can't get the CD to work reliably and there seems to be
some kind of conflict/competition between the VM's and the host for the
CD. I have deleted the CD device from the Windows VM and that has helped.
If I mount a CD on one of the linux VM's, when I unmount it I find I
can't eject it without powering down the host hardware. If I run the
FC14 host without libvirt running all seems normal.
I'm sure there are some simple steps I'm missing because having to power
off the whole box to eject a CD is a bit of a time waster.....never mind
having to shut down the other VM's that are there.
Thanks
Ken
