RE: [Xen-devel] [PATCH 0 of 5] Add credit2 scheduler (EXPERIMENTAL)

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

Thanks.  Unfortunately, after updating both hypervisor
and tools to cs21173 (from staging), xend seems to start fine, but
attempting to launch a domain yields:  

Xend has probably crashed!  Invalid or missing HTTP status code.

An immediate "xm list" shows that xend has not crashed
(or perhaps silently and successfully restarted), but
re-attempting to launch a domain yields the same message.

(George, no need to point out that this is probably
unrelated to the credit2 scheduler... but that would
imply that xen-unstable-not-staging is also broken.)

Keir, if staging passes your regression tests successfully
without the problem I am seeing, please let me know.
(And I'll try rolling back to 4.0 for now.)
