I cannot talk about GPFS as a basis for KVM clients (we use SAN/LVM for our
VM disks) but up to 2.6.8 SLES11 SP1 on both x86 and ppc works fine as a
hypervisor w/in xCAT...
I don't see why GPFS wouldn't work, however the closest we've come is using
CNFS over GPFS FS for statelite VM's, which works but has it's own little
gotchas...

I don't know if you intend to use SLES11 SP1(2?) with xCAT, but I will say
it's been a while since it was explicitly tested. RHEL6 series is
currently the best tested hypervisor. If SLES keeps libvirt and
perl-Sys-Virt current (maybe requiring SP2), *shouldn't* be an issue, but I
haven't done it for sure lately.
I have been intending to move from the socat/nc burdened qemu+ssh uris to
the more apathetic qemu+tls uris as the primary mechanism, and have laid
the groundwork to do so in 2.7, just haven't taken advantage. This is of
little practical concern to most users as xCAT currently hides away the
mess, but it does slow down 'unreachable' returns somewhat.
GPFS AFAIK should be fine. We've been a bit NAS and local storage heavy in
our virtualization testing, and we probably should construct a SAN topology
with GPFS for completeness.

It should work just fine. It is on my list of things to test.
