I was in the process of moving a VM from a XCP 1.1 to XCP 1.6 host. I shut down the VM and exported it and then imported it to the new host. Everything went fine until I try to boot the VM. Any help or advise is much appreciated.
Here’s problem 1:
There’s the error when I try to boot the VM on the new XCP 1.6 host. Has anyone seen this?
[root@xen65 ~]# xe vm-start vm=srch-plgr00

Here’s problem 2:
I tried to boot the VM in the original XCP 1.1 host, and it still won’t start. I have seen many posts state boot issues after a kernel update relating to pygrub. However, I didn’t do any kernel update, and this looks like an invalid argument in “ramdisk.”
[root@xen04 ~]# xe vm-start vm=srch-plgr00
Error code: Traceback (most recent call last):

I compared grub.conf to a known good bootable VM on the same host, and it looks the same. I don’t see anything wrong ramdisk(initrd) parameter.

I tried without success to change the PV-bootable-args to see if that works.

Here’s the params for my VM on the original XCP 1.1 host.
