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/ r...@vmserver.my.com:/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?
