Re: [Xen-users] Limited number of phy disks?

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

As far as I know, the current Qemu implementation in Xen for HVM support does not support SCSI.  As James pointed out, though, if you use the GPL PV drivers, you can assign as many devices as you want to the HVM domU.  The catch to that is that if you ever have to boot with /nogplpv (to disable the GPL PV drivers), you'll lose everything except disk devices hda-hdd.

Hi.

Afaik Qemu supports SCSI disk/adapter emulation nowadays too.. 
SCSI disk support is not yet implemented in Xen (version of Qemu)?
