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

["Phillip Nkubito" <phil@xxxxxxxxxxxxxxxx>]

Hi,

Just some more details:

 - Host is currently running Xen 3.1.2 (shipped with Centos 5.6)
 - The HVM were installed using isos (playing around with turnkey
appliances).

Any assistance/pointers will be highly appreciated.
