Hello,
going through http://www.ovirt.org/wiki/CLI to see some syntax hints.
I don't see a way to get parameter of an object.
For example if I want to see the size of a vmpool, how can I do it
you have two options for this:
1. show vmpool vmpool_name
2. list vmpools --show-all
the vmpool object have size property, if you want to access single property
in returned object, it will be possible after our cli will support pipe redirection.
And is it possible to store values as variables and use then them
for
further commands?
this one of the features i have in my list.
I can run something like this but it seems quite unoptimezed...
output redirection to see how many vms are up in a pool:
[oVirt shell (connected)]# list vms --kwargs
"vmpool-id=eba78b0e-6512-11e1-80c4-5254008e81ee;status-state=up" >
/tmp/testfile
[oVirt shell (connected)]# shell grep id /tmp/testfile | wc -l
2
shell command to see the size of the pool itself, so can I add more
vms to it if the previous :
[oVirt shell (connected)]# show vmpool --name mypool
id : eba78b0e-6512-11e1-80c4-5254008e81ee
name : mypool
cluster-id : 99408929-82cf-4dc7-a532-9d998063fa95
size : 2
I would like only the size value and use it then...
i also have pipe support in my list, when it will be available,
you will be able to redirect shell output directly to grep.
Thanks in advance,
Gianluca
