CPU interupt issuse

Hello Eve-ng community, I was wondering if any of you have had any issues with the following CPU error messages inside of your EVE CLI

root@eve-ng:~#
[125966.9698171 Uhhuh. NMI received for unknoun reason 30 on CPU 2.

Some of the research i did online says that these messages are related to CPU interrupt not being translated correctly

This thread has a similar issue to what i am experiencing.
https://unix.stackexchange.com/question ... g-mode-ena

The thread says that i need to make sure i haev `eoi` enabled inside of libvirt

```
For libvirt, make sure eoi is enabled:

<domain>

<features>
<apic eoi='on'/>


On the command line for KVM that translates to

-cpu …,+kvm_pv_eoi

This seems to work for us with -M q35, host cpu passthrough and default config otherwise (RTC interrupts queued, PIT interrupts dropped, HPET unavailable).
```

I am unsure how to get to the KVM cli.

Anyone who has encountered this issue and found a solution i would love to hear from you. Thanks!
