My shop virtualizes a few hundred SuSE 11.1 servers through IBM's zVM hypervisor. (If you've never heard of zVM, it runs on a mainframe and virtualizes Linux in the s390x architecture. It's a different beast than most of you are used to. The guys who wrote zVM left IBM to form VMWare Inc.)
Currently, we manage our servers manually. We clone new virtual servers from a golden master in zVM, bring the server online, then configure as needed. We rollout maintenance with SMT, but coming from RedHat Satellite Server, SMT features don't compare up to RedHat. (ie run remote commands) If there is a problem with out server, we SSH into the box and fix. If we need to run remote commands on several servers, we either do it manually or use something like PuTTYCS.
My question is what do you recommend as a good provisioning / management tool for my servers and environment?
Some requirements or wishes:
- Open Source and Free
- Does not rely on interfacing with a hypervisor like ESXi
- Unless of course, it interfaces with the zVM hypervisor (I am unaware of any that exist)
- Some sort of Client-Server / Web Interface
That can accomplish sysadmin things like:
- Running multiple commands to multiple servers
- Server Monitoring
- Server Statistics
- Other common sysadmin tasks, etc
I know it's a long shot. But I wanted use my "poll the audience lifeline" and what your input is. I've searched around, but most of my efforts have lead to dead ends or incompatibilities.
