Disk prefix in libvirt template
Hi there.
I've noticed that the "disk_prefix" variable has been removed from the "nova/virt/libvirt.xml.template" file in commit 2c1b9ac ( https://github.com/openstack/nova/commit/2c1b9ac98673c0ef1ae931c6b9d84e4b0741eed9 (https://github.com/openstack/nova/com...) ) and now it is hardcoded on the "nova/virt/libvirt/connection.py".
In our case we are using Xen as the hypervisor, and this is making some of our cloud servers fail since they're are looking for "/dev/xvdX" instead of the coded "/dev/sdX" (this is happening for example with the SUSEStudio appliances) .
Shouldn't this value be configurable in the template again?
