Re: [Xen-users] Xen Support for Sheepdog?

Hm - I was kind'a hoping for something more definitive.

Anyone have any experience using Sheepdog with Xen?

Since sheepdog is supported by qemu it should come for free via the
qdisk PV disk backend.

I'm not quite sure how one would go about actually causing the toolstack
to make this happen though. I suspect it would "just" be a case of
passing some suitable syntax as the target in your disk syntax.

I have a recollection of something doing something similar with ceph in
or around the 4.4 release cycle, which did require a few fixes to the
toolstack side (i.e. not to try and stat() the target path), so
depending on the version you are using you may want to watch out for
that sort of thing.
