Â
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.
Â
Hereâs problem 1:
Thereâs the error when I try to boot the VM
on the new XCP 1.6 host. ÂHas anyone seen this?
Â
[root@xen65 ~]# xe vm-start vm=srch-plgr00

Hereâs problem 2:
I tried to boot the VM in the original XCP
1.1 host, and it still wonât start. I have seen many posts
state boot issues after a kernel update relating to pygrub.Â
However, I didnât do any kernel update, and this looks like an
invalid argument in âramdisk.â ÂÂÂ

I compared grub.conf to a known good
bootable VM on the same host, and it looks the same. I donât
see anything wrong ramdisk(initrd) parameter.
