    I am interested in using cpanel on a VM server. I have a new Centos 5.5 server running Xen 3.

    Are there any issues I should look for?
    Is this a supported configuration?
    The installation went well. I created a PVM running a bare install of Centos 5.5. I have allocated 1 cpu, 2G ram and 100G LMV for drive space. The server seems to running great.

    I plan to host for a couple of non-profits as well as my own business/company sites with static IPs for each site.

    I look forward to the reply.

    Robert,

    All of our VPSes are Xen powered and a good number of them run cPanel flawlessly. CentOS is the best choice as an OS for cPanel as well!

    I was reading that Nat can be an issue. Is that still an issue. My original test build put the host server in the DMZ and used a static nat to the public address. I didn't have a problem with the license.

    What about placing a NetScaler or other load balancer in front of the Virtual host? Is that workable scenario?

    Thanks

    Regarding your first question about Xen ---- works great!

    Xen is far more stable with Cpanel than other virtualized environments

    I don't really recommend running a hosting server outside a data center
    environment and even more strongly don't recommend NAT translation
    be used with Cpanel which doesn't officially recognize any of that.

    While NAT "can" from a technical standpoint be setup with Cpanel, it is
    something that really falls under "expert required" in itself and even then
    is still somewhat of a management nightmare keeping everything synced
    and most all of that deals with a lot of manual editing and re-editing.

    I would agree with you completely about hosting servers outside data centers for the average person. Fortunately, I build data centers networks for a living, on the day job, its the server side that I am weak on.

    I've built out a data center, small scale, at my manufacturing site. We typically place all servers in a DMZ behind load balancers and firewalls, this would include our VM and cloud hosting environments. I can do the same at the data center I have built for my use. I just hate to hang a server out solely behind a packet filter.

    I built out a publicly addressed DMZ last night behind a firewall. That will resolve the issue with NATing. I will still be able to inspect packets and build ACLs for security.

    Thanks

    Hardware firewall is fine ....

    It's the NAT addressing that is the issue ;)
