RE: [Fedora-xen] yum update removes modules for running dom0 kernel!
by You, Yongkang
Em~ I have read your bug.
I am curious that if yum update has installed 2.6.16-1.2080_FC5, why the error still report: Could not load /lib/modules/2.6.15-1.2054_FC5xen0/modules.dep: No such file or directory
Did you reboot the machine with new installed kernel? Is there /lib/modules/2.6.16-1.2080_FC5xen0 there?
Best Regards,
Yongkang (Kangkang) 永康

Can't boot xen0 with ACPI enabled
by Gregor Pirnaver
Computer booting to xen0 hangs if I don't disable ACPI (computer has two Xeon
processors). Even "acpi=ht" doesn't work.
The last lines displayed are many messages like:
...
PCI: BRIDGE ...
IO window: disabled
MEM window: disabled
PREFETCH window: disabled
...
and before that two lines with something like:
PCI: Cannot allocate resource region 4 of device ...
With ACPI disabled it boots normally:
/boot/grub/menu.lst:
...
title Fedora Core (2.6.16-1.2080_FC5xen0)
root (hd0,0)
kernel /xen.gz-2.6.16-1.2080_FC5 acpi=off
module /vmlinuz-2.6.16-1.2080_FC5xen0 ro root=/dev/VolGroup00/LogVol00
module /initrd-2.6.16-1.2080_FC5xen0.img
...
Is there anything I can do to get hyper-threading working?

RE: [Fedora-xen] configuration for windows image with VT machine
by You, Yongkang
Hi Matthias,
I think the bootloader is installed at /dev/sda, which can select to boot the Windows XP partition right?
You can modify /etc/xen/xmexample.hvm to change to following configuration and create the VMX with it.
disk = [ 'phy:/dev/sda,ioemu:hda,w' ]
sdl=1
vnc=0
vncviewer=0
Creating Windows VMX has no difference with other unmodified Linux.
Best Regards,
Yongkang (Kangkang) 永康

Subject: [Fedora-xen] configuration for windows image with VT machine
Hi,
i have a brand new system with VT technology (HP XW4300).
i am running FC5 with XEN kernel 2.6.16-1.2080_FC5xen0 on it.
on the harddisk (/dev/sda) there are two partitions. sda1 has a native windows XP system installed while sda2 is /boot and sda3 is / for the FC5 system.
now i want to run the windows system under xen control using the installed windows system on the first partition.
what would i need to configure to make this work ?
how does the config file needs to look like ?
is there a documentation available on how to make windows run unmodified under xen ?
any hints welcome !
Thanks.
!

guest domain boot hangs at "Freeing unused kernel memory:"
by Murat Işık
hello,
I am using fc4 image from http://jailtime.org/download:fedora:fc4 on fc5
with xen. however when I run "xm create fedora.fc4.xen.cfg -c", the boot
sequence hangs at "Freeing unused kernel memory:". my cfg is:
kernel = "/boot/vmlinuz-2.6.16-1.2080_FC5xenU"
memory = 128
name = "fedora.fc4"
vif = ['']
dhcp = "dhcp"
disk = ['file:/xen/fedora/fedora.fc4.img,sda1,w',
'file:/xen/fedora/fedora.swap,sda2,w']
root = "/dev/sda1 ro"
I found this about the problem:
http://wiki.xensource.com/xenwiki/XenFaq#head-ea8b39d71e49cc16d287257de4c...
however I checked for the devs and they are there:
mount -o loop fedora.fc4.img /mnt/
ls -alh /mnt/dev/
total 8.0K
drwxr-xr-x 2 root root 4.0K Sep 22 2005 .
drwxr-xr-x 21 root root 4.0K Feb 10 08:07 ..
crw------- 1 root root 5, 1 Sep 22 2005 console
prw------- 1 root root 0 Apr 27 2005 initctl
crw-rw-rw- 1 root root 1, 3 Sep 22 2005 null
crw-rw-rw- 1 root root 5, 0 Sep 22 2005 tty
crw-rw-rw- 1 root root 1, 5 Sep 22 2005 zero
Also the lines
[2006-04-05 00:29:27 xend] DEBUG (blkif:24) exception looking up device
number for sda2: [Errno 2] No such file or directory: '/dev/sda2'
and
[2006-04-05 00:29:27 xend] DEBUG (blkif:24) exception looking up device
number for sda1: [Errno 2] No such file or directory: '/dev/sda1'
are interesting since all files are in place.
Any ideas?
have a nice day.

no eth0 device
by Eric Smith
Hi,
With clean FC5 install followed by yum upgrade, and after installing xen,
kernel-xen0, and kernel-xenU:
I boot into kernel-xen0 ok, xend starts, things like xm list work, but my
eth0 device is not found at boot time. Booting into the non-xen kernel and
it works as expected. eth0 is Broadcom 4400 10/100BaseT Ethernet.
Perhaps I'm missing the main xen documentation, but I didn't see anything
about this in the quickstart guide.
Thank you for your help,
Eric

FC5 Xen Guest install failed
by Guillaume Menguy
Hi,
Strictly following the FedoraXenQuickstartFC5 wiki
(http://www.fedoraproject.org/wiki/FedoraXenQuickstartFC5), I get blocked at
the following step :
/usr/sbin/xenguest-install.py -n fc5template -f /xenimg/fc5template -s 6 -r
512 -l http://xen1
The installation starts and a few seconds after the network configuration, I
get :
loader received SIGSEGV!. Backtrace:
[0x8049865]
[0xad2420]
[0x8063ca0]
[0x805e5e1]
[0x804ad21]

install exited abnormally

/proc done

/sys done

you may safely reboot your system
If your install has exited, you can restart your guest by running
'xm create -c fc5template'. Otherwise, you can reconnect to the console
by running 'xm console fc5template'
xend.log says :
...

I tried on another server with a new install : same problem. Server has 2 Gb
RAM and enouth disk space.
Thanks for any help.

Problems with network interfaces
by Walter Souto
Hi everybody,
I'm new to that list and I did read the archives to see if somebody
have something like my problem but I can't find anything.
I did a clean install of FC5 and Xen using yum. Then I did create one
guest using pyguest-install. Everything runs ok. The guest works, but
I have experimented some kind of problem with the network of the
guest. I can't ping the domain0 and the domain0 can't ping the guest.
But how I did keep trying more two or three times and the guest start
to responding. Tried again and no response, tried again and have
response... So I'm lost here.
I did make another guest by copying the image of the first guest,
change the mac addr on the config file (in the /etc/xen) and changing
hostname, IP addr and mac addr to the same that used in the config
file for the new guest. I did create the two guests and they work ok,
but the same problem still occurs. One time I have the two guests
responding, then, one of the two are working and the other not...
The machine is an old PIII600EB with 768Mb RAM. Each guest was created
with 256Mb and the domain0 itself has 235Mb. Maybe that machine is not
sufice to run Xen with two guests.
I'll apreciate any help.
TIA,

Walter.

Problems with Xen + FC5 + Thinkpad
by Brad Smith
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello all,
I recently upgraded from FC4 to FC5 on my Thinkpad T30 laptop and am looking forward to playing with
Xen. However, I've hit a few stumbling blocks along the way. Following the instructions at
http://www.fedoraproject.org/wiki/FedoraXenQuickstartFC5
I installed the Xen0 kernel and booted my system with it. However it hangs, seemingly forever, at
the "Starting xend" stage. The OS seems ok as keypresses are still printed to the screen, but
because the daemon never completes its startup process the boot sequence never finishes. Upon
rebooting I noticed an error that gets printed while the kernel is loading, which says that it could
not bind IRQ2 to guest because it is in use by cascade. This happens consistently, so I wonder if
it's a hardware problem?
I booted the system into single user mode and chkconfig'd xend off, booted normally and attempted to
start the daemon post-boot. It printed a message about starting the Bridged Firewall, which I had
not seen during bootup, but still seemed to hang indefinitely.
Oh, and SELinux is loaded but not enforcing. Should that be sufficient?
Does anyone have suggestions for how I might further troubleshoot this?
Thanks,
- --Brad
