network problem after upgrade...
by John Sanabria
hi,
i had two machines (shutdown and init) dedicated as domain0 with fc6 and
xen installed. Both machines has guest domains deployed. Last days, i
decided to update the shutdown machine with kernel and xen packages, using
update software tool (aka. pup). As consequence my old guest domains in
shutdown machine has network problems, cannot communicate outside, then i
decide to deploy a new guest domain, after to updating process, and it
does not have any problems. The problem appear with old guest domains. :-(
But, the old guest domains in init machine (with no updates) work properly.
any suggestion? thanks a lot.

XEN-3.0.3 on RHEL-5, fully virtualized guest of RH72 won't start after install finishes.
by Ben Russo
I have many boxes running rh-7.2
(these are stripped down, minimal installs, for appliances on a private
network that isn't routable) I want to run VIRTUAL images of the
same setup for testing purposes.
I read the Fedora 6 XEN getting started guide and skimmed through the
FAQ. I browsed through this mailing list to see if I could find my
problem here as well. No luck.
I have a Dell-2950 with Quad Core XEON processors, PAE, VMX, and it is
enabled in BIOS. 8GB RAM, 2GB assigned to Dom0
Booted into RHEL-5 Xen kernel, installed all the latest patches as of
6/11/2007, and rebooted.
Then Started Virtual Machine Manager GUI
Selected "New..." from File menu and followed the wizard.
then installed FULLY VIRTUALIZED
RH-72 from original Red Hat 7.2 CD's
this went fine with the
Virtual Machine Manager GUI "New Machine" wizard.
The only non-usual thing I did for an RH72 install was
to give it the kernel boot option mem=500M
After the install completed, the DomU guest said it was now going to
reboot and I should remove any CD's.
Then the DomU disappeared.
It took me forever to figure out that I couldn't use the virt-manager
GUI to restore a DomU configuration file. There really should be
a more intuitive way for this to work. I am not a dummy, and it took
me forever to figure out how to start the DomU again.
Now that I figured out that I have to go to a command line prompt and
type "xm create -c /etc/xen/rh72-test",
I find out that the new guest gets a kernel panic on bootup
after the bootup menu
Unfortunately the messages scroll by really fast, and I can't catch
them all, but at the end, the last page visible in the VNC console
says:

Any ideas?

multiple CD ISO image files with qemu-kvm and virt-manager on F7
by Chris Young
I can't seem to get access to the qemu monitor console to change the
location of the cdrom and point it to the next iso image file using
virt-manager. Ctrl-Alt-2 sends me to the serial0 console and Ctrl-Alt-3
sends me to the parallel0 console, both of which don't respond to
keyboard events as far as I can tell.
Is there any other way of connecting to the qemu monitor console?

can't create domU after failed install
by Ranbir
Hello Everyone,
I'm trying to use virt-install for the first time to create a
paravirtualized CentOS 5 domU on a Fedora Core 6 dom0. Here's the
command I used:
virt-install -n pbx -r 256 --vcpus=1 -m 00:16:3E:66:94:5D --vnc krs -p
-l http://blizzard/mirror/centos/5/os/i386
I'm then prompted to enter the disk I want to use, at which point I
enter "/dev/vg00/asterisk" (a LV I previously created). At this point,
the install appears to start, but eventually fails, giving this reason:
Starting install...
ERROR: Domain named pbx already exists!
There was a "pbx" config file in /etc/xen, but even after deleting it, I
get the same error when I try to recreate the domU.
I assume I can clear this from "memory", but how? Rebooting dom0
doesn't help, so I'm assuming virt-install is pulling that info from
somewhere.
Regards,
Ranbir

fedora core 7 and Xen

I've disabled selinux, tried building my image in /var/lib/xen/images/
and several other places. I've removed and reinstalled xen virt-maanger
kernel-xen, I've tried an upgrade from 6-7, changed settings in my
config for cpus, mem, ethernet bridging.
I'm running Xen on a dell 2900 with 4 Xeons (x86_64) with the vt flags,
8 gb ram and a 1000 gigs of disk space.

Formatting pauses during install
by Tarun Reddy
I'm using Centos 5 dom0 on an x86_64 machine with 12GB of RAM.
Tried to use virt-manager to install a Centos 4 domU (also tried with
Centos 5 domU) but the tool limits the disk to 16000 MB. So switch to
using virt-install and specified an 80GB disk. Everything proceed
well until "Formatting / file system" which stops at 11% (~8GB of the
74GB / partition).
Are there hard limits here that I'm missing?
Thank you,
Tarun

F7 guest on a F7 host
by Greg Huber
I'm trying to install a F7 guest on a fresh F7 host.
I get all the way through virt-install and then open the guest.
I see a blip of text and then the screen goes blank and nothing
further happens, no disk or CDROM activity, and certainly no
install screen. After I 'shutdown' and 'run' I get....
HVMAssist BIOS, 1 cpu, $Revision: 1.38 $ $Date: 2005/05/07 15:55:26 $
ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (16400 MBytes)
ata0 slave: Unknown device
Booting from Hard Disk
Boot from Hard Disk failed: not a bootable disk
FATAL: No Bootable device.
Which I assume means that nothing got loaded to the guest.
The same happens in text mode also.
If, however, I use a Fedora Core 6 install disk or a Windows XP install
disk,
I can complete the install.
I used the F7 install disk to build the host system and the media has been
checked. I also tried NFS mounting the image from another machine.
Thank You.

Making Xen Guest Console Bigger
by Robert L Cochran
I'm brand new to using Xen. I've just successfully installed Fedora 7 as
a guest system named F7guest with 618 Mb of memory and approximately 35
Gb of disk space. How do I make the console bigger so that I can
actually work on applications? The default console is way too small --
the whole desktop window is about 6X6 inches. I need the actual desktop
and application windows to fill my 19" monitor and be resizeable for
them to be any good to me.
Thanks

Xen kernel missing drivers?
by Steve Brueckner
I have a Dell Optiplex 745, which is new enough that it uses the Intel 965
chipset and SATA optical drives. Due to this newness, no Fedora versions
prior to 7 will even install on it. I believe this is because of drivers
missing in Anaconda.
Anyway, Fedora 7 will install, but when I install the Xen rpms
(xen-3.1.0-0.rc7.1.rc7 and kernel-xen.2.6.20-2925.9.fc7) and try to reboot
using the xen kernel, the machine freezes. It freezes shortly after a
series of timeouts and errors that look like this:
ata1.00: qc timeout (cmd 0xef)
ata1.00: failed to set xfermode (err_mask=0x4)
ata1.00: limiting speed to PIO0
failed to recover some devices, retrying in 5 secs
ata1.00: disabled
(repeat above series a few times)
ata2.00... (similar set of errors)
...
No volume groups found
VG_host not found
Why might the standard Fedora7 kernel work OK, but the Fedora7 xen kernel
not work? Is it perhaps because of missing drivers in the xen kernel?
How can I fix this problem? Do I need to give up on the xen rpms, and try
to compile xen from source, but using the Fedora7 kernel instead of a
vanilla Linux kernel?
Thanks for any thoughts.
