[Xen-users] DomU Kernel Panic with 2.6.31.6 pv_ops

["Chen Peng" <chenpenghit@xxxxxxxxx>]

Hi, all

I have successfully built and started up Dom0(CentOS 5.4) with 2.6.31.6 pv_ops.
When I wanted to start up a DomU, it come up against kernel panic.

The DomU(CentOS 5.4) configure file is as following:
kernel = "/boot/vmlinuz-2.6.31.6"
memory = 256
name = "vm1"
disk = [ 'file:/tmp/images/vm1.img,xvda,w' ]
root = "/dev/xvda ro console=hvc0"
extra = "3"

The error messages are as following:
