The kernel of your choice. We don't do kernels and hypervisors as matched
pairs these days. A recent pv_ops kernel ought to work with either 4.0 or
4.1.

XenServer trunk is currently running on xen-4.1-testing tip (minus the 3
changesets today) (plus a patch queue).
I am not aware of any outstanding hypervisor issues.

I am seeing problems building 4.1.3-rc1 on Fedora 17, though it might be
changes in Fedora 17 rather than xen changes that have triggered it. When
trying to compile objects such as scheduler.c in tools/blktap2/drivers I
get the error
/usr/include/features.h:329:3: error: #warning _FORTIFY_SOURCE requested but disabled [-Werror=cpp]
On checking that file I see that this is because -Wp,-D_FORTIFY_SOURCE=2
is requested with -O0 . Fedora 17 decides to warn about this and it
becomes an error as -Werror is specified.
This conflict occurs because of the line
CFLAGS += -Werror -g -O0
in tools/blktap2/drivers/Makefile
I can of course work around the problem in my build, but I was wondering
if optimization level 0 is still necessary for this code. I think the
only other place -O0 is used now is tools/security/Makefile which I
assume will also trigger the problem.

Thanks. The same appears to be true in xen-unstable also. Is the solution to
simply remove -O0 from the command line? We can test that out in
xen-unstable if so, and backport if it causes no problems.

I got it to build with the attached patch -
http://koji.fedoraproject.org/koji/taskinfo?taskID=4063767 .
It seems the -O0 option was masking some other compile issues so I had to
add -Wno-error=unused-result -Wno-error=array-bounds as well though I
imagine the right solution would be to fix the code so it doesn't give
warnings (if they haven't already been fixed in xen-unstable).

If it is failing -Warray-bounds then the source code probably needs fixing.
Do you have a log of the failures caused by -Warray-bounds ?

Keir,
the changes to unmodified_drivers//linux-2.6/ should be backported to
the 4.1 branch:
changeset: 25069:46bf3ab42baf
changeset: 25067:05768bd498f2
optional:
changeset: 24045:4ed766d70396
changeset: 25068:e4460795ee66
Also the asm/system.h patch I sent out today is a candidate.
