As oracle puts more time and money into it’s virtual servers, it’s going to become more common. I’ve been dabbling with OVS at a client that is going to be using it in their live environment. We were having some problems with multipathing, but seemingly because nobody filled out the multipath.conf file with an vendor settings – so everything was vanilla out of the box and would not work.
Once this was rectified, a bit of an audit was performed. I was doing some research and found references to an RPM (vmpinfo-2.2-3.noarch.rpm), which is available on https://support.oracle.com. This is an awesome script which does a post installation battery of tests and checks and creates a pretty cool (nerdy cool) HTML based report.
install is trivial: rpm -i vmpinfo-2.2-3.noarch.rpm
Then just run it, vmpinfo.
There are a couple of example outputs on https://sites.google.com/site/cncninja/file-cabinet, as well as the installation rpm.
This could be used for any generic host checking I think - but is specific for OVS and looks for specific OVS problems.
