Thanks - this did the trick! For my and others education, what is this

can't start my xen guest
by Darren Birkett
I successfully installed a fc5 test3 guest, using the anaconda install
method via the xenguest-install.py script. Now when I try and start the
guest, I get
[root@xentest1 ~]# xm create -c guest1
Using config file "/etc/xen/guest1".
Error: [Errno 17] File exists
even though this guest has never been started.
[root@xentest1 ~]# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 192 1 r----- 873.0
[root@xentest1 ~]# xm destroy guest1
Error: Domain 'guest1' not found when running 'xm destroy'.
Any ideas?

where is xenU kernel?
by Darren Birkett
Apologies if this is a very basic question, but I'm just trying xen out. I
have used the install script from xensource to download and install xen-3
for FC4. I have booted into dom0 using the kernel
vmlinuz-2.6.12.6-xen3_7.1_fc4, and that's all fine. When I go to create a
guest, and edit the config file, I don't appear to have a xenU kernel to
point to in the config file. From what I understood, there should be a
separate unpriviledged kernel to use for the guests, so where is it? If I
try and do a "yum install kernel-xenU" it installs a xenU kernel for xen-2
(or so xen-debug.log tells me if I try and use it in the config file for
creating a new domain).
I may just be getting myself confused, so any help appreciated.
Cheers

kernel-xen-guest-2.6.15-1.1955_FC5 seems to eat filesystems
by Steven Pritchard
I updated my Xen test box to rawhide a few days ago, and I was happy
to find that it not only booted the hypervisor kernel (which hadn't
been working on this old dual PIII), but the guest kernels started up
too.
Now it looks like the filesystems on all three guests I was running
are trashed. The first one I checked was so bad that e2fsck
segfaulted when I tried to repair it.
The host itself checks out fine, so it doesn't seem to be a problem
with kernel-xen-hypervisor.
Is this a known issue, or something I should bugzilla?
Oh, and these three guests were happily running for months on FC4...
Luckily they were disposable though. :-)

OK, will try on 32-bit too.

Out of interest, what happens if you boot without SMP, either by
disabling HT in the bios or giving the hypervisor the "nosmp" boot
option? There may be a bad HT scheduling performance problem here; it
would be useful to eliminate that possibility.
My own boxes are either pure UP or genuine not-just-HT SMP, which may be
why I don't see this.

Xen on x86_64 and "Could not allocate 8 bytes percpu data" kernel messages
by Aleksander Adamowski
I've just booted an Opteron HP Proliant server into
2.6.15-1.1955_FC5hypervisor fo x86_64.
The machine has booted and network communications are working, but there
were a couple of suspicious messages on the console during bootup:
"Could not allocate 8 bytes percpu data"
Here's a longer excerpt from the logs:

Are those messages dangerous?

Errors installing more than 1 guest OS on XEN Fedora core 5 test2

If your install has exited, you can restart your guest by running
'xm create -c qwe3412'. Otherwise, you can reconnect to the console
by running 'xm console qwe3412'
