Home Assistant on haos_ova.dvi 6.6

Hi all,
I have been running Home Assistant for a few years on Raspberry pi and after several small issues I decided to move to Virtual Machine on an old Mac Mini running virtual Machine. I followed the instructions on several sources and finally have it running but I have struck one major issue and am struggling to find out what is causing it.

After running for a while I loose connection with the Home Assistant and I see the attached image as the screen on my apple server

I have looked through the logs but see nothing that would tell me what is going on, any help would be appreciated

Looks like your host machine may be set to shut-down to save power after periods of inactivity. Disable that.

Hi Tom,
I set all the energy features to never turn off and left it run overnight, didn’t make any difference
