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.

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?

Architecture:
XCP-ng 8.3 on a RAID 10 Dell server.
VirtualBox on a Windows 11 PC
Debian13.1 Trixie on the VirtualBox with XO source installed (per Tom L videos).
XO opens in browser and works well.

PROBLEM:
Drag and drop ISO's from Windows to Virtualbox Deb13 fails.
After install of VBoxGuestAdditions to enable file sharing, Windows to VBox file share works BUT VBox Deb13 XO is no longer available as a website.

How to get Debian 13 on VirtualBox to drag and drop files without breaking XO??

Need to import multiple ISO's and also some VMware machines.
