Subject [jira] [Commented] (CLOUDSTACK-9083) Add disk serial to vm/libvirt xml in case of KVM
Date Mon, 30 Nov 2015 09:41:11 GMT


ASF subversion and git services commented on CLOUDSTACK-9083:

Commit 12c395b56052af36901ab3ed1a366ed8985740eb in cloudstack's branch refs/heads/4.6 from
[;h=12c395b ]

CLOUDSTACK-9083: Add disk serial to kvm virt xml

Adds disk serial ids based on volume uuids to the virt xml. This may be useful
for appliances/software that needs some serial ids on the VM disks. This does not
impact existing/running VMs, the vm virt xmls will be updates for running VMs
the next time they are stopped/started.

For testing, disk serial (of debian based systemvm) in the virt xml matched that
in /sys/devices/pci0000:00:0000:00:07.0/virtio4/block/vda/serial.

We currently don't support scsi-blcok devices for which serial is not supported,
for this we've added a DeviceType (LUN) which may be used in future and a check
to not add the serial to the xml if disk type is LUN.

The fix would be to add a disk serial (from volume uuid) in the generated libvirt xml for
all disks except for lun/scsi block type disks (which we don't support yet, so we can add
in a deviceType for now and leave some comment).
