Attaching non-PCI block devices to VM

[Noor Christensen]

Hi,

I am curious if it is possible to attach "arbitrary" block devices to a
VM, similar to how additional disks drives can be specified for HVMs.

For example, let's say I have a backup disk image on dom0 that I would
like to read from another VM without having to copy the entire file. Is
this possible?

Yes, have a look at 'qvm-block -a' and 'qvm-block -A' in dom0.

Also remember you don't have to use dom0 or sys-usb as a source; you can
specify any VM that contains the volume.
