I still doing research on finding a Web host for a VPS. One issue that worries me is that all of them seem to offer only what I would consider a small amount of RAM. I would be running seven Web sites. Of course, they are all non-commercial, and my traffic is not that great. (I want a VPS only because I want root access and want to do things myself, i.e., learn and play.)
Is 512 MB, for example, really enough to run my own installation of CentOS, Apache, the Virtuozzo panel, cPanel, and seven Web sites?
That strikes me as incredible since my two home computers, running Fedora 12, have 2 GB and 4GB of RAM!
Conversely we’ve got customers using 16GB+ of RAM for a single site - you just can’t make a blanket statement without knowing what the sites are running, how they are designed/built and how much traffic they get
I believe you always can ask your current web hosting provider to give you full information. I believe thaey are the ones who recomended you to shift to VPS?
Cpanel and other stuff will use up to 128MB of RAM.
I think that your provider do provide you guaranteed and burstable
Get 512 MB of guaranteed RAM and that would be enough.

I suppose that is not a problem to find some information about usage of CentOS, Apache, the Virtuozzo panel, cPanel.
All what you need is find out how much RAM is needed for your 7 sites.
Kindly ask you current web hosting provider about that.
Good luck
I’d say that it’s probably possible but I’m SURE that you won’t be able to run all the daemons at the same time and, if you spawn multiple cPanels for different clients, I’m just as sure that you’ll overwhelm your VPS and be shut down by your host until your load decreases (that’s happened to me with 768Mb with burst to 1024).
Shop around and compare host offerings but be sure to ask about the cost of additional RAM (if they offer it).
