which branch is recommanded to use for pvops dom0?

[Zhang, Yang Z]

Hi jeremy
Now we use xen/stable-2.6.32.x for testing. But I found the xen/stable-2.6.33.x is ready? Should we move to it?

best regards

There is no xen/stable-2.6.33; there might have been at one point, but
it was never more than a placeholder.

What kind of work are you doing?

Mainline Linux contains a lot of dom0 support now, but not quite enough
to usefully run a domain.  We're in the middle of preparing a 2.6.38-rc
based branch which will be more complete.

xen/stable-2.6.32.x is still the most feature-complete branch, but it is
more or less in a maintenance state, and will probably only get bugfix
updates.

I am focus on the validation with hvm guest.

Ok, I see. If there have any new recommended candidate, please let me know. Thanks.

Speaking of which I now have a reliable repro for "d0:v0 unhandled page
fault (ec=0000)" early-boot crash.

Go in to a file in the kernel and add the following:

unsigned char foo_bar_baz_furfuu_quux[1<<20];

Turns out that it is related to kernel image size after all. The crash
happens regardless of which section the big variable gets linked in to
(ie. text or data).
