Re: [xcat-user] KVM/RHEV Setup

[Er Tao Zhao]

Hi, Mark

 

If I understand correctly, what you mean are:

 

For the KVM/RHEV(head node) hypervisor or host, it will be an VM, right?

You are define the host node as below, then you can use rpower <on/off...> to operate it. 

 

# lsdef <headnode> -z
# <xCAT data object stanza file>

<headnode>:
    objtype=node
    cons=kvm
    groups=all
    mgt=kvm
    netboot=xnba
    vmhost=<hypervisor host ip for head node>     ===> This is the hypervisor ip for the head node, you must configure the passwordless access from xCAT Management Node to this IP address.

 

Thx!

 

Best Regards,

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.

Mark,

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

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? ------------------------------------------------------------------------------
