sVirt Initial Prototype Release

James Morris requested[1] comments on an initial prototype of sVirt[2] v0.10. sVirt was first mentioned in FWN #138[3].

"The purpose of this release is to establish a proof of concept of applying security labels to VMs, and for discussion of the underlying technical approach.

With this release, it is possible to define a security label for a kvm/qemu domain in its XML configuration ('virsh edit'), launch the domain and have it transition to the specified security label ('virsh start'), then query the security label of the running domain ('virsh dominfo')."

Hot-add SCSI/VirtIO Disks for KVM Guests

Guido Günther supplied[1] a patch to add hot plugging and unplugging[2] of SCSI/VirtIO disks for KVM guests.

Domain Events Support Completed

After three[1] rounds, Ben Guthro's domain events patches have been committed. This major API addition led[2] Daniel Veillard to speculate that the next release version number may jump to 0.5.0. Domain events are only emitted from KVM guests. The other hypervisor drivers will require more work to properly emit domain events.

The python bindings are forthcoming. [3]
