[Users] clone vm from snapshot problem in 3.2

[Alexandru Vladulescu]

Hi all,


I am facing the same problem regarding the VM clone & viewing the 
details from snapshot as Gianluca has described in this current thread.

The single problem I am facing now, is that your thread is from 3 months 
old, I am using el6 stable repository on a CentOS 6.3 installation and 
my rpm list below looks like:

ovirt-engine-sdk-3.2.0.10-1.el6.noarch
ovirt-engine-webadmin-portal-3.2.1-1.beta1.el6.noarch
ovirt-engine-setup-3.2.1-1.beta1.el6.noarch
ovirt-engine-userportal-3.2.1-1.beta1.el6.noarch
ovirt-engine-dbscripts-3.2.1-1.beta1.el6.noarch
ovirt-engine-3.2.1-1.beta1.el6.noarch
ovirt-engine-cli-3.2.0.11-1.el6.noarch
ovirt-engine-tools-3.2.1-1.beta1.el6.noarch
ovirt-engine-genericapi-3.2.1-1.beta1.el6.noarch
ovirt-engine-backend-3.2.1-1.beta1.el6.noarch
ovirt-engine-restapi-3.2.1-1.beta1.el6.noarch

As I can see, there were some revision set updates on the ovirt engine 
core rpms, that I suppose, it should include this as well: 
http://gerrit.ovirt.org/#/c/11254/

Can someone provide me some piece of advice on how to fix things ?



Thanks you.
