It is quite some time I am receiving queries on ovirt-shell/ cli usage. Even-though I didn’t store those questions with me, I thought I will point something on this topic. Soon I will come up with more notes on this topic. Upto that, this is a place holder draft. But, dont get disappointed, you have below urls which has enough details on it.
