I'm running off of VirtualBox Oracle hypervisor. I have made several attempts to get at least one of these working. I think I finally have the Mint running, but just in case I run into any more problems, I'm looking for specifications for component allotments and other necessary settings; memory, storage, video memory, any checked or unchecked boxes I may need to implement. I am looking for the same sort of thing with the Ubuntu installation on VB Oracle, which I have yet to reinstall.
You posted here in the ISPConfig 3 forum. Do you want to install an ISPConfig 3 server? If not, I'll move your post into the general Linux section.
