I have NZBget and Plex installed in Apps and 2 VM's Windows 10 and Debian10. I set 8GB for RAM for each VM. When starting the VMs I see the above message Available Memory: 0/10 bytes. I can start the VMs after ticking a box acknowledging a problem with lack of memory. Both Windows10 and Debian10 VMs boot to UEFI interactive shell. I haven't gotten the Windows10 VM to boot but I have gotten the Debian10 VM to boot but I am stuck in a login loop. Only booting into UEFI shell and login loop are for another day. I wondered if the login loop was caused by lack of memory but there are other possibilities.
I have read many posts about setting a tunable for arc and I am still not getting it.
I understand going to ui/system/advanced then "Add Sysctl"
This was an example I found from last year for a FreeNAS system. I don't know the correct command nor do I understand what value to put for Value.
