The QEMU open source machine emulator has been updated to version 1.0. Notable features include:
- QEMU now supports live migration of running guests.
- KVM users are now able to run standard performance profiling tools within KVM guests.
- QEMU and libvirt now support image streaming. Image streaming lets an administrator start new virtual machines quickly based on existing images; virtual machines are then provisioned completely in the background as they run.
- QEMU and KVM support a new advanced SCSI-based storage stack, virtio-scsi. Support for this new storage stack will be added to libvirt in a later release.
