[xcat-user] KVM/RHEV Setup

[Mark Potter]

I have been tasked with doing some internal training on xCAT. Since I have a nice, stable RHEV setup I have everyone setup with their own private lab environment and so far my testing has gone well. The only bit I can't figure out is power control. I've been through the docs and have seen where xCAT can handle power when it knows about RHEV and is deploying the virtual machines but that's not what I need. This is supposed to simulate a physical environment. Is there a way to have xCAT control power from a virtual head node on virtual nodes that weren't created by xCAT?

Mark,

I do not think xCAT can do that. In order for xCAT to control power, it
needs an object definition to operate on.

While true it will have an object definition as it will be deploying the nodes just not the VMs. RHEV does have an API that allows for VM control. If OpenIMPI’s lanserv doesn’t work out I’ll be looking in to adding the functionality to control RHEV/KVM instances via the API and trying to integrate that in to xCAT.

Check out LanServ/IPMI Sim. I've never tried it but it looks promising:
https://github.com/wrouesnel/openipmi/tree/master/lanserv

lanserv is a program that provides a LAN connection for a BMC that
does not otherwise have a LAN connection. It takes a standard Linux
IPMI device and implements the IPMI LAN protocol.

ipmi_sim is a full IPMI simulator and does not require a real BMC. It
can be used to simulate an entire IPMI system, including satellite
MCs. You can use it over a LAN connection, or it provides a serial
interface so it can be used with QEMU or other VMs. The serial
interface implements the serial protocols available on many ATCA
blades, and it also emulates a protocol so it may be used for
emulation of a standard IPMI interface (KCS, SMIC, BT, SSIF) including
the handling of reset, power, and interrupts.

That's the direction I'm heading at present.
