I liked Anthony's suggestion of an lvm2 block format driver. No polling.
Doesn't that require giving QEMU privileges to perform LVM operations which
implies QEMU having CAP_SYS_ADMIN ?
If QEMU is able to resize an LVM partition, it needs to carry privileges.
I'm not sure how this can be done safely in a lesser privileged
environment. Presumably, you're over committing storage and there's not
much you can do if the guests exhaust their storage all at once.
