xen-utils-4.1, pygrub, xvda1, "Boot loader didn't return any data!"
Hello,
xen-utils-4.1's pygrub is unable to boot VMs from a partitionless
blockdev that has grub installed in first sector. I'm not sure it
deserves a bug report, although it is kind of a regression from 4.0.
Long story short: zeroing first sector of domU's boot blockdev fixes it.
Maybe some of this report would be useful in the wiki, if someone else
has the same (odd) setup.

Xen PV domU reported as Xen-HVM
Hello,
I am running two dom0s, one on CentOS 5 with Xen 4.1.2 (from Gitco) and the
other one on CentOS 6 with Xen 4.2.4 (from Xen4CentOS). I host one LVM
based domU on both from the same template (CentOS 6 PV) with the same Xen
config (see below). However, the domU on Xen 4.1 reports itself as Xen PV
while the domU on Xen4CentOS reports itself as Xen HVM.

Cannot open root device xvda1 or unknown-block(0,0)
Hi
I''m putting together a Dom0 and three DomU (all Gentoo) with kernel 3.5.7 and
Xen 4.1.1. Each Dom has it''s own md (md0 for Dom0, md1 for Dom1 etc). Dom0
works fine so far, however, I''m stuck trying to create DomUs. It appears the

Arch linux PV guest won't boot

Slow IO on DomUs under Xen 4.1 kernel 3.2.0.4
Hello,
I hope this is the mailing list to discuss this issue, but if not sorry
for spamming!
I just discovered a really slow IO performance on DomUs running debian

takes a lot of time.
Here are the hardware parameters:

XEN DomU isn''t starting...
Hi guys!
I installed XEN 4.0 on Debian Squeeze but I cannot get the first DomU
(not an image) started.
Attached you will find /etc/xen/xen1.conf and the result of "xm create
-c /etc/xen/xen1.conf" in xen1.log.
Can you help me? What did I wrong? Is it about the fstab in xen1 (see
also attached)?
Many thanks in advance!

New DomU on older Dom0
Hi,
I have a Xen server running OpenSuSE 10.2, with Xen version 3.0.3_11774.
It''s happily hosting two DomU''s running the same OS / kernel.
Now I tried to create a new DomU running a newer OS - OpenSuSE 11.1. It
comes with Xen version 3.3.1_18494_03.
Unfortunately for me, it doesn''t work - this is what I get:

I can''t solve my problem. I want a 32 bits Lenny domU into a 64 bits

I plan to use pygrub for that (xen 3.2.1).
So, I tried to debootstrap a 32 bits domU into a 64 bits dom0.
