This needs to be declared unsigned long long. If you configure with
--enable-compile-warnings=error then the compiler will catch these sorts
of errors.

should work with this.

The reason I created this is because I also wanted to find the length of
the segment so I could add it to the parsing offset to check what was
next in the string. That level of checking may be unnecessary
(overkill), and in any case could be more easily achieved using
something like sscanf for some token portion of the string. As I said, I
am *certain* there is a prettier way to do this!

People can fetch those (based on RHEL-5.1 rpms base) from
http://veillard.com/NUMA/
the kernel-xen and xen(-devel) should be sufficient . Server is on my ADSL
line please do not DoS it or I will be even slower than usual :-)

Somehow I missed this part of the note last time. Thanks for the catches.

My results are a bit inconclusive. I have a machine here which
supposedly supports NUMA (2 socket, 2 core AMD with hypertransport and
two separate banks of RAM).
BIOS is _not_ configured to interleave memory. Other BIOS settings lead
me to suppose that NUMA is enabled (or at least not disabled).
Booting with Daniel's Xen & kernel does not give any messages about NUMA
enabled or disabled. (See attached messages).
# numactl --show
physcpubind: 0 1 2 3
No NUMA support available on this system.
$ grep -i numa /boot/config-2.6.18-numa.52.el5xen
[ no configuration lines shown ]
Nevertheless, with Beth's patch I see:
# src/virsh freecell 0

My results are a bit inconclusive. I have a machine here which
supposedly supports NUMA (2 socket, 2 core AMD with hypertransport and
two separate banks of RAM).
BIOS is _not_ configured to interleave memory. Other BIOS settings
lead me to suppose that NUMA is enabled (or at least not disabled).
Booting with Daniel's Xen & kernel does not give any messages about
NUMA enabled or disabled. (See attached messages).
# numactl --show
physcpubind: 0 1 2 3
No NUMA support available on this system.
Are you setting "numa=on dom0_mem=512m" on the kernel line in grub?
I'm
not sure if the dom0_mem=512m should be required but we were having
problems when trying to boot numa without it.
It appears from the results you show that numa is not on.
$ grep -i numa /boot/config-2.6.18-numa.52.el5xen
[ no configuration lines shown ]
Nevertheless, with Beth's patch I see:
# src/virsh freecell 0
0: 133292032 kB
# src/virsh freecell 1
libvir: Xen error : invalid argument in
xenHypervisorNodeGetCellsFreeMemory: invalid argument
# src/virsh freecell
Total: 133292032 kB
# src/virsh freecell -2
-2: 0 kB
(Negative numbers should be returning an error).
Yes, a check for negative numbers would make sense.

This is how the information would be interpreted for a non-numa box. All
cpus on one node. You can compare the results with those in xm info. So
if you didn't have numa=on set in grub, this makes sense. Otherwise,
something is wrong.
Rich.

Are you setting "numa=on dom0_mem=512m" on the kernel line in grub? I'm
not sure if the dom0_mem=512m should be required but we were having
problems when trying to boot numa without it.
Aha, the results are quite a bit better now :-)

numactl --show still doesn't work (missing support in dom0 kernel or is
this just completely incompatible with Xen?)
'virsh freecell 0' and 'virsh freecell 1' show numbers which are
plausible (I have no idea if they're actually correct though).
Can I pin a domain or vCPU to memory to see if that works?

Aha, the results are quite a bit better now :-)
virsh shows the correct topology:
<topology>
<cells num='2'>
<cell id='0'>
<cpus num='2'>
<cpu id='0'/>
<cpu id='1'/>
</cpus>
</cell>
<cell id='1'>
<cpus num='2'>
<cpu id='2'/>
<cpu id='3'/>
</cpus>
</cell>
</cells>
</topology>

From /etc/xen/xmexample1:
# List of which CPUS this domain is allowed to use, default Xen picks
#cpus = "" # leave to Xen to pick
#cpus = "0" # all vcpus run on CPU0
#cpus = "0-3,5,^1" # run on cpus 0,2,3,5
If you start a domU with a config set up this way, you can specify that
it run only on node 0 or 1, and then watch the freecell before and after
starting and confirm that the memory was taken from the right node.

virsh shows the correct topology:
<topology>
<cells num='2'>
<cell id='0'>
<cpus num='2'>
<cpu id='0'/>
<cpu id='1'/>
</cpus>
</cell>
<cell id='1'>
<cpus num='2'>
<cpu id='2'/>
<cpu id='3'/>
</cpus>
</cell>
</cells>
</topology>
numactl --show still doesn't work (missing support in dom0 kernel or is
this just completely incompatible with Xen?)
Currently Xen doesn't export any per-domain topology (say a virtual SRAT
table), nor the entire system topology; the goal of the current Xen NUMA
code is to ensure that domains have local resources within a numa-node.
'virsh freecell 0' and 'virsh freecell 1' show numbers which are
plausible (I have no idea if they're actually correct though).

Do we really need such verbose XML. At the very least the 'num' attribute
is redundant, since you can trivially do count(/topology/cells/cell) or
count(/topology/cells/cell[@id=0]/cpus/cpu) XPath exprs in both cases.
The addition of extra tags every time we have a list is not the style we
have normally used in libvirt. eg, we don't use
<disks>
<disk>
..
</disk>
<disk>
..
</disk>
</disk>
to surround the list of disks in a domain.
I'd prefer to see it looking more like this:
<topology>
<cell id='0'>
<cpu id='0'/>
<cpu id='1'/>
<cpu id='2'/>
<cpu id='3'/>
</cell>
</topology>

Dan.

That would simplify the code since the counts wouldn't need to be known
up front. This was the format suggested by Daniel V and I used it,
assuming he knows more about libvirt's desired/required xml structure.

I explained why I preferred a more structured approach and the <cells>
construction when I made the proposal
https://www.redhat.com/archives/libvir-list/2007-September/msg00015.html
basically you may hit hierachical topologies which are not flat.
If you want to remove the nums= that mean that from an user perspective if
you use a streaming interface (like SAX) you can't know a priori the size
of the arrays you need to allocate to fill the information. I prefer something
a bit more verbose and a bit more complex to generate but more flexible
in its use. For me <cells> can't go away for structural needs and the count
is for the number of children at that level not at all levels.
We could get rid of <cpus> but
<cpus num='4'>
<cpu id='0'/>
<cpu id='1'/>
<cpu id='3'/>
</cpus>
could allow things like description in hotplug CPUs situations where the
structure/topology does not change but the content does.
Since that part is rather experimental, I prefer to have more structure
than what may looks like sticly necessary right now but have provisions
for the future.
