| Posted by DHD-Chris, 06-14-2009, 12:24 PM | | I was looking into controlling a few of the features of OpenVZ through a web based interface, I know PHP currently but that's about it. Would anybody be able to give me a few pointers?
Thanks in advance

Example:
Lets say we wanted to stop a container.
Just simply define a variable for container will call it "Container"
Than write the command to run
vzctl stop container.
This is just a very rough example and i'm sure their is many other ways to do something similar to this.

I am taking a guess I would need to use something like perl too, any kind of hints would be great!

Supposedly alpha, I have not used it (I don't have much experience with PHP anyhow). But libvirt itself is quite robust

| Posted by luki, 06-28-2009, 03:47 PM | | You can use any programming language you like to execute vz management commands, however, the concern is security. Typically your web server will not run with root privileges required to manage VPSs. You can work around that with sudo or a privileged daemon/unprivileged client, but be sure you really understand what you are doing or you will be rooted.

| Posted by DHD-Chris, 06-29-2009, 04:58 AM | | I was wondering how do most of these big panels like HyperVM communicate, I know that they use some PHP coding but how do they get PHP to run particular parts of the programs and do things like interacting with services.

| Posted by mwatkins, 06-29-2009, 01:02 PM | | A two-part solution... a smaller "core" that has to run with escalated privileges is accessible to the front end (and likely some scripts) via some sort of remote procedure call mechanism which could be anything from XMLRPC or Soap (ugh) to json requests to corba (ugh) and so on. The client doesn't run with escalated privs. Secure communication between client and core is obviously a must.

| Posted by DHD-Chris, 06-30-2009, 05:37 PM | | Thanks mrwatkins that kinda pushed me a little further. Does anyone know how I would call a script to run using these kind of methods. Which method would you say companies like HyperVM and Plesk use?
