With current git HEAD and the sheepdog driver in qemu-kvm 0.14.1:
# qemu-img create sheepdog:foo 100
Formatting 'sheepdog:foo', fmt=raw size=100
# collie vdi setattr foo wibble wobble
# collie vdi getattr foo wibble; echo
wobble
All good so far. However, after I take a snapshot,
# qemu-img snapshot -c '' sheepdog:foo
# collie vdi list foo
name id size used shared creation time vdi id
------------------------------------------------------------------
s foo 1 0.0 MB 0.0 MB 0.0 MB 2011-07-28 11:05 d9d577
foo 2 0.0 MB 0.0 MB 0.0 MB 2011-07-28 11:07 d9d578
# collie vdi getattr foo wibble
no such attribute, wibble
# collie vdi getattr -s 1 foo wibble
no such attribute, wibble
# collie vdi getattr -s 2 foo wibble
no such attribute, wibble
So it seems to have vanished, neither being attached to the snapshot nor the
head of the vdi.
Cheers,
Chris.
