Looks like I was downloading the wrong ISO.

VDSM enabled versions already exist here: http://resources.ovirt.org/releas=

Subject: [Users] edit-node problems

I'm trying to use edit-node to add the ovirt-node-plugin-vdsm plugin to the=
 ovirt-node-iso-3.0.2-1.0.0.el6.iso that I downloaded from here: http://res=
ources.ovirt.org/releases/node-base/stable/iso/ovirt-node-iso-3.0.2-1.0.0.e=
l6.iso

Whenever I run any edit-node commands against this iso I get the error belo=
w:

# ./ovirt-node/tools/edit-node -dv --print-rpm-manifest /app/iso/ovirt-node=
-iso-3.0.2-1.0.0.el6.iso

If I try the same with ovirt-node-iso-3.0.1-1.0.2.el6.iso (downloaded from =
the same location) all works as expected.

I've tried this on CentOS 6.2 and 6.4, same results on both.

Can anyone tell me where I am going wrong? Alternatively is there a newer n=
ode ISO that already has the ovirt-node-plugin-vdsm plugin installed?

Thanks,

Simon
