yes, but they returns all the properties of an object. I would prefer
to have an option that gives only the value of the property/properties
I'm interested in
something like
show vmpool vmpool_name --props=prop1[,prop2,...,propN]

eg
show vmpool vmpool_name --props=size

Ok, fine to have them.
So in ovirt-shell command, when you type "help" and you get

"
In addition to the basic command form, the following functionality is
  available:
...
    * The output of any command can be piped to a shell command with
      the '|' character.
"
Actually it is not implemented yet, correct?
Because I tried some options but it seems none of them worked...

BTW: getting results seems quite slow in my opinion. Does it depend on
ovirt-shell itself or something I can tune in PotgreSQL RDBMS
parameters perhaps?
