I am running CentOS 5.5 with Xen.
I wanted to make a Xen Debian 5.0.6 OS template so that I can create any number of Guests by just untarring the whole archieve in the new Guest's LVM (I am using LVMs)
So I created a XEN HVM Debian minimal install and shut it down.
After doing that I mounted the LVM using kpartx to map the partition on the LVM.
I mounted it on /mnt/debian
Then I copied the /lib/modules to /mnt/debian/lib/modules for copying the XEN PV modules.
I modified the /mnt/debian/etc/fstab to use /dev/sda1 at '/' and to use /dev/sda2 as SWAP
After that I tarred the whole system :
root > cd /mnt/debian
root > tar --zcvp --numeric-owner -f /root/debain-5.tar.gz *
Then I made the two LVM one for SWAP and the other as the file system.
/dev/vg/debian - This will be mounted as sda1
/dev/vg/debian_swap - This will be mounted as sda2
I mounted /dev/vg/debian and untarred the above archieve in it.
Then I created the following Config :
# START---
kernel = "/boot/myXENvmlinuz"
ramdisk = "/boot/myXENinitrd.img"
name = "debian"
memory = "256"
hostname = "debi.com"
cpu_weight = "256"
vcpus = "2"
vif = ["ip=, vifname=vifdebain.0, mac=myMAC"]
disk = ["phy:/dev/vg/debain,sda1,w" , "phy:/dev/vg/debain_swap,sda2,w"]
root = "/dev/sda1 ro"
serial = "pty"
Then  boot the machine :
root> xm create /etc/xen/debian -c
The machine boots but hangs after starting the CRON.
This is the same thing that happens with Fedora 13 (I created the template the same way)
Virt-Manager shows that the CPU usage jumps to exactly 49.5 - 50 % of the system CPU.
Please let me know what am I doing wrong ???
How should I get this template working ?
