[Xen-users] Kernel panic when trying to create a DomU

[Yangyang <yangyangbm@xxxxxxxxx>]

Hi,all
I'm trying to create a DomU with 'xm create VM1.cfg' but encountered
some problems. It told me there is a kernel panic when trying to boot
the DomU kernel. Does anyone know how to fix it? Thanks for your help.

Part of the error message is:

 Unpacking initramfs...

killable processes...

Below is the VM1.cfg I used to create DomU:
