Hi guys

I am trying to start this newly created KVM VE, and I get this error

Starting Qemu VM 101
qemu: 'file=/var/lib/vz/images/101/vm-101-disk-1.raw,if=scsi,index=0,boot=on' unsupported bus type 'scsi'

any ideas why it is not working or why iscsi won't work? I thought it was SCSI emulation, as this node host is SATA.

Thanks

The kvm version on kernel 2.6.18 has no scsi emulation support - please use ide or virtio instead.
 
I'd like to understand better the reasons for this choice, we prefer to "ide" or "virtio" for instability of SCSI or another?

I'm trying to build a new freeNAS server (freeBSD) with MANY storage devices (more than 4 drives) but apparantly freeBSD does not recognise Virtio drives :(
IDE just wont cut it. I think I might have to downgrade the Host.

some users reported good results with openfiler (using virtio disks), just search the forum.

but are you sure you want to virtualize storage in such a way?
