Hugepages

Hello,

I am running ESXi 6.7 and I have enabled hugapages support as per Huge Pages

but this still doesn't do anything

cat /proc/meminfo | grep -i huge

AnonHugePages:    329728 kB

ShmemHugePages:        0 kB

HugePages_Total:       4

HugePages_Free:        4

HugePages_Rsvd:        0

HugePages_Surp:        0

Hugepagesize:       2048 kB

This should be to 1G

The other parameters seem to go well:

cat /proc/sys/vm/nr_hugepages

4

Can someone help ? as my container doesn't start because of this ....

Hi nfaf1 and welcome to the community!

Can you download your VMX file for the VM and upload to this thread? Remove anything that might be sensitive before doing so Smiley Happy

Kind regards.

Is this a nested ESXi VM ?
Try to set a more appropriate guestOS value like "vmkernel" or "vmkernel6"

Do you need support with a VMFS recovery problem ? - send a message via skype "sanbarrow"
I do not support Workstation 16 at this time ...

Hi Continuum

It is NOT an Nested ESXi VM ... Although the first name misleads to think it could be

This is a VM that runs Kubernetes (and docker) and DPDK and we are making use of Hugepages.

The results are the same with both VM Configurations (both VM configurations posted)

Please let me know

Thanks

I tried to do what you suggested anyway - As I don't have any clue anymore on what to try - But it didn't work

Exact same problem

Please let me know if you or someone can help ?

Thanks

Hi,

as i am facing the same issue, it seems it is related to the hardware/cpu family you are using. so the esXi VM of yours is on top of the hardware but the cpu does not support 1gb huge pages, so it cannot allocate them. if however, the cpu supports huge pages, then check whether you change the eVC from your vCenter on the host to a cpu family that supports hugepages, i am using Sandy Bridge and i know it does not support it.

Regards,

Stamatis
