I tried this way, but seems it
doesnot work.
[root@Dell1 test-pv]# xm cr -c 1-pv.cfg
Using config file
"./1-pv.cfg".
Error: (2, 'Invalid kernel', "elf_xen_note_check: ERROR: Not a
Xen-ELF image: No ELF notes or '__xen_guest' section found.\n")
The configure file of 1-pv.cfg:
[root@Dell1 test-pv]# cat
1-pv.cfg
#----------------------------------------------------------------------------
#
Kernel image file.
kernel = "/boot/vmlinuz-2.6.29"
# Optional
ramdisk.
ramdisk = "/boot/initrd-2.6.29.img"
memory =
512
# A name for your domain. All domains must have different
names.
name = "test-pv"
vcpus = 2
vif = [
'ip=192.168.2.101, mac=00:16:3e:00:10:11, bridge=xenbr0' ]
disk = [
'file:/root/test-pv/vm1disk,sda1,w' ]
# Set root device.
root =
"/dev/sda1 ro"
extra = "4"

domU kernel?
Hi Zyshao,
You can download the
latest kernel from http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.tar.bz2
within your domU, compile it as usual, copy vmlinuz (and initramdisk) to your
dom0 (if you dont use PyGRUB) and start it!
Good luck!

hi pals,
I need to run some HPC applications on the PV Guest (configured with
multiple VCPUs and the application invokes also multiple processes to
communicate with each other during the lifetime), and found that in some
overcommitted cases, the application's performance degrades drastically. I got
a Xen installation with both Dom0 and DomU running "vmlinuz-2.6.18.8-xen"
kernel, i.e., the default configuration.
I am wondering if I can Upgrade the kernel of the PV Guest, i.e., domU,
to run other alternative kernel, such as latest stable linux kernel, 2.6.28.8?
By this way, it may be possible to avoid the performance sacrifice resulted by
spin-lock problem.
Thanks in advance for any suggestions!
