Re: HOST_NOT_ENOUGH_FREE_MEMORY
I have four VM's with enough memory for three (one VM is typically off) we will call that SQL_old .
Total memory for the four exceeds the available memory.
Three VMs run fine. when SQL_old is off.Can I stop one of the three and start SQL_old ?
In other words can I have as many VMs on the machine as I want and only run the ones that fall equal to or below the available memory limit?

@ideal you should, yes.
beware of dom0 memory (the host), it consumes memory too

When all three are on its's like this. I'll turn one off and see if that free's up RAM so I can start the other (after hours). Its a SQL legacy box were trying to get info off of.

@ideal perhaps you could use advantage of dynamic memory
https://docs.xcp-ng.org/vms/#dynamic-memory
to oversubscribe memory and have all 4 VMs up at once... or reduce the allocated memory of your VMs, you seem to have a pretty big VM in terms of memory in comparison to the 2 others on your screenshot
