Hi,
My host only shows one NUMA node. It means that I cannot setup a high performence VM?
Thanks

Hi,
Enable virtual NUMA nodes and setting NUMA pinning topology for a high
performance VM are both suggested configuration changes which are proposed
to the user. Both are not a mandatory configuration.
Therefore, you can still set a high performance VM even if your host
doesn't support NUMA (i.e. only one NUMA node exists). Just ignore those
recommendations appear on the High Performance VM popup after saving the
VM's configuration.
Regards.

I see, Thanks
For the huge pages, do I need to configure the kernel or just use the value of 1048576,
which is the recommended one?
Thanks

Hi,
First you'll need to configure the host's kernel parameters to use huge
pages (2M or 1G on x86).
Then in case you want to use huge pages for your high performance VM, set
it via Custom Properties to tell oVirt which size of hugepages to use for
that VM. Our recommendation is to use the same size as set for the host.
Please check [1] for more details on how to configure your VM.
One of our colleagues wrote a blog post that is a bit old but may help:
