Hi Roger and thanks for your time and efforts.
I thought XENBUS_PATH was some sort of a reference to the xenstore
path of the VM being executed and that the libxl would export that to
the hotplug scripts. I thought that simply allowing the libxl to execute
hotplug script for blk devices would be enough.
Can I be of any help? Feel free to pass me work I you're busy.
OTOH, I wasn't aware it could involve the Dom0 kernel. I'm confused
about that, could you please explain me why it does involve the dom0
kernel?
Thank you,
Gus
PS: a bit offtopic, but I've been reviewing the commits to FreeBSD
HEAD and I don't see this:
https://people.freebsd.org/~royger/mem.patch
IIRC that patch solved the problem of domU PV guests with some
hardware. Could you commit that upstream?
