[one-users] failed to attached disk in KVM

[Jaime Melis]

Hello,

I'm digging this thread up because I just found out the reason why this
could be happening. Apparently RHEL/CentOS doesn't have support for scsi
drivers in its kvm version. I suggest you use this device prefix: "vd"
(virtio) and try again.

cheers,
Jaime
