Re: [PATCH 34/35] qemu: Allow <transient> disks with images shared accross VMs

Implement this behaviour by skipping the disks on traditional commandline and hotplug them before resuming CPUs. That allows to use the support for hotplugging of transient disks which inherently allows sharing of the backing image as we open it read-only. This commit implements the validation code to allow it only with buses supporting hotplug and the hotplug code while starting up the VM. When we have such disk we need to issue a system-reset so that firmware tables are regenerated to allow booting from such device.
