Hotplug of virtio(block/net) devices not detected inside ppc64el guest

Following the patchworks link this seems to be being disputed as the right approach:

"I'm not sure about that one ..." from BenH.

Can we get Ben to comment on where we are going first.

Latest comments from submitters: "Meanwhile the patch http://patchwork.ozlabs.org/patch/327089/ is not ready yet for inclusion, and the kernel team is still working on the fix."

Unless told otherwise, I'm going to assume the 1.2.20 update of powerpc-ibm-utils resolved this.

Adam,

All needed userland components have been patched, as described in Bug 1282426.

The kernel patch is now in Ben's next branch:
