When playing with NUMA support recently, I noticed a host would always
hang
when trying to create a cpupool for the second NUMA node in the
system.
I was using the following commands:
# xl cpupool-create name=\"Pool-1\" sched=\"credit2\
# xl cpupool-cpu-remove Pool-0 node:1
# xl cpupool-cpu-add Pool-1 node:1
After the last command, the system would hang - requiring a hard reset
of the
machine to fix.
I tried a different variation with the same result:
# xl cpupool-create name=\"Pool-1\" sched=\"credit2\
# xl cpupool-cpu-remove Pool-0 node:1
# xl cpupool-cpu-add Pool-1 12
It turns out that the RAM was installed sub-optimally in this machine.
A
partial output from 'xl info -n' shows:
numa_info :
node: memsize memfree distances
0: 67584 62608 10,21
1: 0 0 21,10
A machine where we could get this working every time shows:
node: memsize memfree distances
0: 34816 30483 10,21
1: 32768 32125 21,10
As we can deduce RAM misconfigurations in this scenario, I believe we
should
check to ensure that RAM configuration / layout is sane *before*
attempting to
split the system and print a warning.
This would prevent a hard system freeze in this scenario.
RAM placement should not matter here. As the name already suggests
cpupools do assignment of cpus. RAM allocated will be preferred taken
from a local node, but this shouldn't be mandatory for success.
Would it be possible to use a debug hypervisor (e.g. 4.12-unstable) for
generating a verbose log (hypervisor boot parameter "loglvl=all") and
sending the complete hypervisor log?
I don't have a package for 4.11 or 4.12 built at all - but I did this on
4.10.2-pre (built from staging-4.10).
Managed to get the same crash log when adding CPUs to Pool-1 as follows:
