[Xen-devel] Hot plug scripts not working c/s 19355 (was: Re: [PATCH] xen: mask XSAVE in cpuid since we don't allow guests to use it)

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

A heads-up that I just got a "(tap)...Hotplug scripts not working"
completely unrelated to pvops.

I updated hypervisor and tools (but notably NOT dom0 kernel) to
xen-unstable c/s 19355.  Launching a domain now fails with the
above error.  Rolling tools (only) back to 19187 makes the
problem go away.

Is there maybe a new dependency between tools and dom0 kernel?
