Hello,
so final working solution for 8-NUMA node configuration is:
With this configuration, virtualized Debian 9 even slightly outperforms the
same Debian
9 on the bare metal.
As of io

Hello,
so the current domain configuration:
hopefully, I got it right.
Good news is, that spec benchmark looks promising. The first test bwaves
finished in 1003 seconds compared to 1700 seconds in the previous wrong case.
So far so good.
Bad news is, that iozone is still the same.

Hello,
I did some performance measurements with SpecCPU 2017 in variant fp rate
(i.e., utilize all cpu cores). It looks like this:
8-NUMA Hypervizor specfp2017 - 124
1-NUMA Hypervizor specfp2017 - 103
2-NUMA Hypervizor specfp2017 - 120
8-NUMA Virtual (on 8N Hypervizor) specfp2017 - 92
1-NUMA V
Hello again,
when the iozone writes slow. This is how slabtop looks like:

Hello,
ok, I found that cpu pinning was wrong, so I corrected it to be 1:1. The issue
with iozone remains the same.
The spec is running, however, it runs slower than 1-NUMA case.
The corrected XML looks like follows:
In this case, the first part took more than 1700 seconds. 1-NUMA config
