All,
I was recently testing the workings of virtio to provision SAN block devices
to a domain, which worked great! However, i could not find a way to find the
UID of a virto_blk device. The scenario I had created was the following. a
LUN provisioned to my KVM (kvm-83) hypervisor over two paths, both paths
mapped to my domain using virtio_blk. When configuring multipath-tools in
the domain I could not find a way to find the UID of the LUN in order to
create the multipath config. On a SCSI device, I would use the
/lib/udev/scsi_id tools to discover this ID. I am using libvir/qemu 0.5.1 in
Ubuntu Jaunty Alpha-3 as hypervisor and virtual machine.
Does the virtio_blk driver provide a UID to its devices, and is there a way
to get this ID in userspace?
kind regards,
