Hello,
I am using the official Haos qcow2 VM-Image. I have assigned two virtual CPUs to the VM.
In the HA Webinterface, the CPU Load averages 10%.
On the Host, the CPU load averages 40%.
The Host CPU is an i5-6500.
Best regards,
Hendrik

The virtualization layer is probably not included in the GuestOSes measurement.
A GuestOS thinks it runs on hardware and CPU cycles needed to emulate that hardware is not available to it.
Hello,
yes, I understand that there is an Overhead. But it should not be a factor of 3-4…
Also, when I just run a debian VM the overhead is minimal.
Greetings,
Hendrik
just noticed you do not even compare the same figures, because the programs are probably run in different spaces.
In my case, when running top
in both Guest HA OS and Host, HA runs around 2%, but Host shows qemu-system-x86
running around 30%. I have spent a fair bit of time tuning parameters trying to get this down (Host cpu pass-through, etc) , but no luck.
