Read-only iscsi disk? Or hot-plug?

Hello, I have an iSCSI disk with a backup. I want to use that backup on another machine to test putting back data. What I use now is this: ---- <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='directsync' io='native'/> <source dev='/dev/disk/by-id/scsi-36e843b6afdddf65dc4e9d4dc2dab66de'/> <target dev='vdh' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0c' function='0x0'/> </disk> ---- Is it possible to do this read-only? What I also could do is to hot-unplug the disk at the production machine, and then hot-plug it at the test-machine. But the machines are Windows, and I don't know Windows well.
