Where to install fake_ilo

[wantit]

Hi,

Can you tell more where we need to install this script, in other node or VM. I try to to add this to node but come out with error that i need to auth.

Hello, the script needs to be installed on the host.

What error exactly are you getting? Which user are you running this as? If not root - is the user member of the "libvirt" group on the host?

thank for response. i try running ilo.py directly. when I am try to test my power management. I get this error

libvir: XML-RPC error : authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found)

Looks like you have authenitcation set up, try checking this:
http://wiki.libvirt.org/page/Tips#The_connection_fails_using_md5_digest_auth

What distro are you using?
Did you try to run the script as root/sudo?

[wantit]

I am using centos and already run as root. Now I am disable libvirt authenitcation. But now i cannot get list of vm from other host.

Basicly this is what i am doing.
node1 : vm001 with fake_ilo
node2 : vm002

I try to set power manager at node2 and at fake_ilo only list vm001

Oh, I get it. I never tested that, my script will probably require changes to support remote libvirt nodes. The quickest solution right now would be to set fake_ilo on both nodes separately. After all it's just a test tool so not intended for such a "wide" use.

Or you can modify the script and share results if you want!

Thanks. I try to follow this video http://www.youtube.com/watch?v=uHCnXGUMaS0 but in russian.

can you tell me a little how to use fake_ilo

anyway thanks again

First of all, the whole point I wrote the script was to record that video: I needed something that would emulate a fencing device to show off the HA functions of oVirt.

In my case there was a single Debian sid box running libvirt without authentication. As I understand, this setup works for you as well, so you installed the script successfully.

If you describe your use case we may try to find a better solution or modify the script a bit. Please share with me what you're planning to use this for.
