Description of problem: When floppy/cdrom image is missing, snapshot-revert will report error even if with startupPolicy='requisite' Also the error message is ambiguous "Unknown error 512" and need to be improved Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.232.el6.x86_64 kernel-2.6.32-225.el6.x86_64 libvirt-0.9.10-3.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.Start a guest with qcow2 type disk image and a floppy disk like <disk type='file' device='floppy'> <driver name='qemu' type='raw' cache='none'/> <source file='/var/lib/libvirt/images/floppy.img' startupPolicy='requisite'/> <target dev='fda' bus='fdc'/> </disk> 2.Create snapshot of running guest # virsh snapshot-create guest 3.Destroy the guest and remove image /var/lib/libvirt/images/floppy.img 4.Revert to running snapshot # virsh snapshot-revert [snapshot name] Actual results: report error: error: cannot access file '/var/lib/libvirt/images/floppy.img': Unknown error 512 Expected results: should revert successfully Additional info:
