No pcifront in F10?
by Jim Lutz
I have a virtual machine landscape consisting of a CentOS 5.3 Dom0 with
Xen 3.1.2, some PV CentOS DomU's with PCI passthrough (same versions),
and I'm trying to implement a F10 DomU with PCI passthrough. I set
everything up for the passthrough, and the F10 guest can't see any of
the devices with lspci. If I boot a CentOS PV machine with the same PCI
passthrough configuration, the devices show up with lspci. I've seen
some posts in various places about this issue, but no solutions. How do
I implement this?

Dom0 to rawhide?
by W. Michael Petullo
I have been using Michael Young's Xen Dom0 kernels. With kernel 2.6.34
in Rawhide, what is keeping Xen 4.0 and a DomU kernel from being pushed
to Rawhide? My understanding was that kernel 2.6.33 would provide the
pvops features required to make a Dom0 kernel palatable to Fedora. Did
this feature not make this release?
http://fedoraproject.org/wiki/Features/XenPvopsDom0 has not been updated
in a while, but I suspect that a Xen Dom0 kernel will not be in Fedora 13.

Move from Fedora 8 dom0s to F12/F13 dom0s with Xen 4.0.x questions
by fcxen user
I would like to try to move some dom0s from Fedora 8 to Fedora 12/13/Xen 4.0,
but I had a few questions. Some of these are probably repeats so I apologize
in advance.
* I use "virsh define" to create the VM configurations using virsh xml, and I
assume that virsh/libvirtd won't work on a recent 2.6.32/33/3x kernel and Xen
4.0.0
Is there a way to extract the xm style configuration values from the running
VMs? Or a file somewhere so I can pull out/copy the VM configs for use on the
new machine or is there another way to do that? It has been since about Fedora
Core 5 that I used the xm style configs so I don't have that in my head like
many on this list do.
* I am using plain disk files for the storage for each VM, I understand that
Xen 4.0 has the ability to use these now with the correct kernel. Is that the
case? Would I be able to use my current (F10-F12) VMs as is?
* Although Pasi, Michael, Dale and others have been very generous with their
information, testing and development, I am not completely clear on all the
steps required to get a working F12/F13/ Xen 4.0.X dom0 with 2.6.32/33/3x
kernel starting from a base F12/F13 system install. If someone can point out
where to find different parts I would be grateful and would be willing to
consolidate them into a single blob if that doesn't already exist. I looked at
some of the wiki some on the xen wiki but I get a bit of choice overload from
those pages - you can use this kernel or that kernel or...
* If this were to work, would I see a performance increase or (hopefully not)
decrease for vanilla F10-F12 domUs (apache, etc) on the same hardware going
from Xen 3.1.4 on F8 to Xen 4.0.x on F12/F13 on Intel 5400/5500 based servers?
Thanks for any help.
One of the other reasons I want to upgrade is because I can no longer add VMs
with virt-install command line. I constantly get:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
virDomainLookupByID() failed GET operation failed: xend_get: error from xen
daemon:
Even after upgrading to libvirtd 0.4.6-1.fc8 and even immediately after
rebooting the dom0 - which seemed to be a workaround for others that I read
about having this problem. I realize this is not the libvirtd list but a
couple of the replies to this problem that I have seen are along the lines of
"it is not a libvirt problem". And If it is not too painful to get the F12/F13
dom0s working with my old VMs, I hope to just forget all about this :)

Per Keir's feed it's not supposed to be functional on F13.
If i am wrong about that , please advise.

Yeah, I think it misses the boat. Maybe 3.4.4 if there is some developer
interest in cherry-picking the patches, and sufficient testing effort.

Fedora 13 rc as Xen PV guest test report
by Pasi Kärkkäinen
Hello,
I just tried installing Fedora 13 release candidate as Xen PV guests/domUs:
- F13 rc 32bit PAE Xen PV guest (kernel 2.6.33.3-85.fc13.i686.PAE)
- F13 rc 64bit Xen PV guest (kernel 2.6.33.3-85.fc13.x86_64)
Xen dom0 for these tests was RHEL 5.5 x86_64.
I installed F13 guests using virt-manager and http fedora mirror.
Both installed OK, no problems found. Absolute mouse pointer worked OK
on the graphical console.
RHEL 5.5 has pygrub support for ext4, so having F13 guest
/boot on ext4 (the default for F13) is not a problem anymore.
I also tested save/restore functionality:
- F13 64bit guest with 1 and 4 vcpus: save/restore OK.
- F13 32bit PAE guest with 1 and 4 vcpus: save/restore OK.
