Problems installing Xen
by Chip Motley
Hello,
I set up my first dual boot with Fedora 6 and WinXp. The partitions were
setup as shown below. My problem occurred after the installation of Xen.
When I went to /boot/grub and looked at grub.conf there was no reference to
Xen. I ran "Xend start" and received the following message:
ERROR: Could not obtain handle on privileged command interface (2 = No such
file or directory)
ERROR: Could not obtain handle on privileged command interface (2 = No such
file or directory) Traceback (most recent call last):

xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (2, 'No such file or directory')
I looked in the Yum.log and found the following:

How do I install Xen correctly? PS I am new to Linux

destroydevice
by Jordi Prats
Hi,
It seems there's a problem on 2.6.19-1.2895.fc6xen xen kernel and the xm
tool: creating a new VM it aborts showing this error:
[root@inf16 ~]# xm create /etc/xen/rata.cfg
Using config file "/etc/xen/rata.cfg".
Error: destroyDevice() takes exactly 3 arguments (2 given)
[root@inf16 ~]#
Anyone knows what is causing this? On the xen-users list there's some
other messages related to this isue (one mine). Mats Petersson say that
this may be causes by a backport.
There's something broken on the package? There's any easy workarround?
Thank you,

DomU boot on Fedora 6 fails with 'VFS: Cannot open root device'
by Anne Facq
Hello
I have got a problem booting a DomU on Linux Fedora Core 6 (kernel
2.6.19-1.2895.fc6xen)
I did the following operations :
1) dd if=/dev/zero of=/home/xen/vm1 bs=1k seek=6144k count=1
2) mkfs.ext3 /home/xen/vm1
3) mount -o loop /home/xen/vm1 /mnt
4) cp -ax /{root,dev,var,etc,usr,bin,sbin,lib,boot} /mnt
5) mkdir -m 755 /mnt/{proc,sys,home,tmp,mnt}
6) DomU fstab :
/dev/sdb1 / ext3 defaults 1 1
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
7) cat > /etc/xen/vm1
kernel = "/boot/vmlinuz-2.6.19-1.2895.fc6xen"
memory = 512
name = 'vm1'
vif = [ '' ]
disk = [ 'file:/home/xen/vm1,sdb1,w' ]
root = '/dev/sdb1 ro'
extra = 'ro selinux=0 3'
8) When I launch :
xm create -c vm1
I get the following error message :
----
VFS: Cannot open root device "sdb1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
----
I tried several devices but I got the same message
Any advice ?
Thanks in advance.

Re: VNC and FreeNX disrupted is lost under XEN Dom0 kernel (mouse and keyboard are frozen) - resolved
by Jan Andrejkovic
Hello,
I resolved the problem by installing 3rd party graphic driver. My
motherboard is Via J7F2WE2G and in the xorg.conf I had defafult Vesa driver.
This driver caused below problem under FC6XEN kernel (also under
2.6.19-1.2911.fc6xen). I also noticed that under FC6XEN my xorg log had this
error at the end:
Fatal server error:
Caught signal 11. Server aborting
As I explained the server was working but because of this error it was not
working properly.
The problem was resolved by installing Via OpenChrome drivers from
http://washington.kelkoo.net/epia/ and also I updated Xorg.conf using 'X
-configure'

Jan

XEN Problem with root device
by Claus Reheis
Hi all!
At first I have to admit that I am very inexperienced in using XEN!
What I try to do is get OpenSuse 10.2 working on my FC6 Station.
To do that I did the following steps:
1)Installed the XEN Kernel: 2.6.19-1.2911.fc6xen
2)Installed OpenSuse 10.2 on my girlfriends Laptop
3)made a complete image of the installation and put it in my home:
/home/user/opensuse102xen.img
4)created an suse.xen.cfg:
kernel = "/boot/vmlinuz-2.6.19-1.2895.fc6xen"
memory = 512
name = "opensuse102"
vif = ['']
#nics = 1
#dhcp = "dhcp"
disk = disk = ['file:/home/rehcla/opensuse102xen.img,xvda,w']
root = "/dev/xvda ro"
5)did edit the /etc/fstab in the Image:
/dev/xvda / ext3 acl,user_xattr
1 1
#/dev/hda1 /windows/C ntfs
ro,users,gid=users,umask=0002,nls=utf8 0 0
#/dev/hda2 swap swap defaults
0 0
proc /proc proc defaults
0 0
sysfs /sys sysfs noauto
0 0
debugfs /sys/kernel/debug debugfs noauto
0 0
usbfs /proc/bus/usb usbfs noauto
0 0
devpts /dev/pts devpts mode=0620,gid=5
0 0
When I try to start Xen with:
"xm create opensuse102 -c suse.xen.cfg"
I get this:
Using config file "./suse.xen.cfg".

Console is unavailable
by Ciaran Byrne
Hi,
I hope you don't mind me contacting you like this, but I got your emails
from an inconclusive discussion about the following subject. I am
experimenting with virtualization in RHEL 5 Beta 2, and everything
appears to go well until I try to connect to the console of the new
virtual machine. The error includes the message "connection refused".
There is no qemu-dm process running and /var/log/xen/qemu-dm.3598.log
contains the following line:
xc_get_pfn_list returned error 22
I have attached xend.log for today in case it helps.
Incidentally, I seem to have found that there is no way to recover the
new virtual machine after I have installed Fedora unless I save it just
before the final reboot. I then do virsh restore xen-machine1.saved. I
am hoping this is the right thing to do.
Many thanks,
Ciaran Byrne

Problem renaming Logical Volumes
by Daniel Tuijnman
Hi all,
Sorry if this is not really a Xen problem, but it is something which you
wouldn't want to do if you were not playing with virtual machines...
I had one small VM set up to use as a base for other (paravirtualized) VM's.
(both dom0 and the domU's in question are Fedora Core 6 installs).
I gave it a LV, say /dev/VG_domU/base, as its (only) disk /dev/xvda, and
partitioned it during install as follows:
/dev/xvda1 /boot filesystem
/dev/xvda2 PV for VG VG_base, with LV's
swap for swap
root as / filesystem
which is the way I usually partition my Linux installs (except that I
usually create LV's for /usr, /var, /tmp, /home etc.)
Then in dom0, I created another LV /dev/VG_domU/derived, did a dd from
/dev/VG_domU/base to /dev/VG_domU/derived, et voila, I have another VM.
But this other VM has on its disk a VG with the same name, so I wanted to
rename the VG: you never know if you want to access both VG's at the same
time.
So I used kpartx to make it visible:
# kpartx -a /dev/VG_domU/derived
# vgscan
# vgrename /dev/VG_base /VG_derived
Then, of course, the name of the VG are mentioned a number of times:
- in /boot/grub/grub.conf the name of the root partition
- in /etc/fstab
- and in /init on /boot/initrd...img
But after that, the cloned VM with the renamed VG wouldn't boot - kernel
panic.
Does someone has an idea what I'm missing here?
Greetings,
Daniel

Preparing a Dom0 Kernel
by David Pilger
Hi,
What is the procedure to build one of the kernels from these
repositories (http://hg.et.redhat.com/kernel/) to function as domain0?
I built kernel 2.6.19.2 and tried to boot it with Xen. The function
elf_xen_note_check prints the following error:
"ERROR: Not a Xen-ELF image: No ELF notes or '__xen_guest' section found.
Thanks in advance for your help,
David.
