[Xen-users] Creating a para virtualized guest using 'xm'

["Kumar, Venkat" <Venkat.Kumar@xxxxxxx>]

I am trying to create a para-virtualized guest VM (Fedora core Linux) using xm tool.

 

I am following the “Professional Xen Virtualization” book by Wrox to do this.

 

Here is what I am doing.

 

1. Downloaded the root file system and swap file system from http://jailtime.org/lib/exe/fetch.php?cache=cache&media=download%3Afedora%3Afedora.fc8.20071216.img.tar.bz2
2. Using dom0 kernel and initrd images for domU as well.
3. The configuration file that I use is

kernel = "/boot/vmlinuz-2.6.21.7-3.fc8xen"

ramdisk = "/boot/initrd-2.6.21.7-3.fc8xen.img"

memory = 428

name = "fedora.fc8"

vif = [ '' ]

dhcp = ""

disk = ['tap:aio:/var/lib/xen/images/fedora.fc8.img,xvda1,w', 'tap:aio:/var/lib/xen/images/fedora.swap,xvda2,w']

root = "/dev/xvda1 ro"

4. When run xm create on the above configuration file, xend crashes and the error message is “Xend has probably crashed!  Invalid or missing HTTP status code”.
5. dmesg outputs the following after clearing the messages and executing xm create.

“python[10576] general protection rip:3ead6097d3 rsp:44600a10 error:0”

 

What could be wrong?

 

With virt-install tool we specify the type of guest we can create with –p or –v option. But incase of xm how it distinguishes b/w PV and HVM guests.

 

Thx,

Venkat
