Hmm yes that can be easily problem if Xen qemu uses some different
disk ioctls which are not supported by dm driver.
I think that ideal would be change disk_ioctl routine to work with
more that one IOCTL and listen for all other different disk size
ioctls calls. disk_ioctl can use dictionary to create every possible
structure for caller.
Please make a PR for this issue because otherwise it can be lost.
Because I'm little bit busy these
days with ZFS.
