Xen devel - Jul 2008 - [PATCH] qemu-xen: Fix extendable images

Hi Ian,

I''m not completely sure about this one. The question is what you really
wanted to achieve with that BLOCK_DRIVER_FLAG_EXTENDABLE thing. I
suspect that you just put it into the wrong struct accidentally
(bdrv_host_device instead of bdrv_raw), but I might be wrong. Changing
it allows me to use qcow2 images through tap:ioemu again - in fact, I
think it fixes extendable images in general, i.e. also for HVM.

Please check if the attached patch makes sense and apply if appropriate.

Kevin
