Re: [libvirt] [PATCH 1/1] Add a simple pool type for multipath devices

This pool type contains volumes for the multipath devices that are

that aspect of system administration must still be done at host build time.

Hum, the way I read this is that f you give no specific option to
configure, check turns into a with_storage_mpath" = "yes" and then if
device-mapper-devel is not available configure fails, while I would
expect check to not fail in that case and switch with_storage_mpath to
no , I afraid this can be confusing, or I'm the one confused :-)
