Here's how far I've progressed this evening: $ dd if=/dev/zero of=/recover2.my.net.raw count=20M $ losetup /dev/loop0 recover2.my.net.raw $ cfdisk /dev/loop0 create a 9G bootable linux partition and a 1G swap $ kpartx -a -v /dev/loop0 $ mkfs.ext4 /dev/mapper/loop0p1 -m 0.01 -L "RecoverTest" $ mkdir tmp $ mount /dev/mapper/loop0p1 tmp >From the backup server: $ rsync -av tree/ root@xxxxxxxxxxxxxxx:/srv/pool/tmp/ $ umount tmp $ kpartx -d /dev/loop0 $ losetup -d /dev/loop0 $ virsh attach-disk recovery.my.net --source /srv/pool/recover2.my.net.raw --target sdb But no joy from the running VM itself. It does not show sdb, only its own vda1. rescan-scsi-bus.sh fails to bring make /dev/sdb appear. Is the hotplugging failing perhaps? Suggestions?
