I''m investigating what would be required for a DomU''s block device to be resized (well... grown at least) without having to reboot the DomU. Does the commercial product support this?

I don''t think it would be a lot of code to support this.. the upstream Linux kernel already supports SCSI disk online resizing. Also RHEL 5.3 kernel supports online SCSI disk resizing.
