Re: [Libvir] [RFC][PATCH 1/2] Tested NUMA patches for available memory and topology



Richard W.M. Jones wrote:

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.

# src/virsh capabilities
[...]
  <topology>
    <cells num='1'>
      <cell id='0'>
        <cpus num='4'>
           <cpu id='0'/>
           <cpu id='1'/>
           <cpu id='2'/>
           <cpu id='3'/>
        </cpus>
      </cell>
    </cells>
  </topology>
[...]

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.
