[Xen-users] Fully-Virtualized XEN domU not Booting over iSCSI

["Phillip Nkubito" <phil@xxxxxxxxxxxxxxxx>]

Hello,

I am currently trying to move my VMs from running on local host storage to
a shared storage (trying out iSCSI) but I am
facing a bit of a booting dilemma.

The domUs are a mix of paravirtualized and fully-virtualized VMs. They all
boot and run like clockwork when on local
storage.

The paravirtualized domUs appear not to have a problem when I relocate and
boot them from the shared storage
though the fully-virtualized ones give me an error on bootup.

************************************************************
Boot from Hard Disk failed: could not read the hard disk
FATAL: No bootable device
************************************************************

The iSCSI is offering the domUs as file images (.img) to the initiator i.e
.Type=fileio.

My host's processor (as you may have deduced) supports Intel-VTx. Does my
shared storage need to have this capability to be able to
boot my fully-virtualized domU?

Any pointers/suggestions would be appreciated.

Phillip
