Snapshot only supported the qcow2 image format which was poorly implemented qemu 0.10.2. Snapshot support may be restored in the future when the newer upstream qemu is used by Xen. - bnc#776995 - attaching scsi control luns with pvscsi - xend/pvscsi: fix passing of SCSI control LUNs xen-bug776995-pvscsi-no-devname.patch - xend/pvscsi: fix usage of persistant device names for SCSI devices xen-bug776995-pvscsi-persistent-names.patch - xend/pvscsi: update sysfs parser for Linux 3.0 xen-bug776995-pvscsi-sysfs-parser.patch - Update to Xen 4.2.0 RC3+ c/s 25779 - Update to Xen 4.2.0 RC2+ c/s 25765 OBS-URL: https://build.opensuse.org/package/show/Virtualization/xen?expand=0&rev=199
