If I am running only one server, is there a reason to use a virtual server application? The reason I'm asking is I wondered if I need this for ubuntu 10.10 web server.
Virtual servers have some advantages, for example you can simply move them to a new server (you don't have to set up the virtual machine from scratch as you'd have to do with a physical server), and it's easier to do backups - you can simply back up the whole virtual machine. Not if you don't use virtualization; only on OpenVZ hosts.
When I tried to run this i came up with errors. It hung up on "vzctl set $VPSID --capability ${CAP}: on --save" because I had to install vzctl... was that file suppose to have been installed during the tutorial, prior to this section? I couldn't tell what all was being installed to tell the truth. Once I installed it and tried to re-run everything... it said it failed. I think this was the PM I sent, and don't have a copy in my sent file.... Now I don't remember the exact fail notice language... it's in the PM.
I guess you dont run a openvz system as the vzctl command was missing, so you dont need to execute these commands. Running them on a non virtual server host will cause the errors you posted above. So just dont execute these commands, as they are not nescessary for your server.
This was a fresh install, so I wasn't thinking the installation was for an existing system... I'm pretty new at all this <my narrow view> Thanx for the feedback... it's always appreciated.
