Re: [Users] Is there a way to force remove a host?
This conversation is fine but if I want to force remove no matter what I should be able to from the GUI. The nodes are no longer available I want to get rid of them ovirt does not let me. I can delete from database but why not from the GUI? I am sure others may run into this problem as well.

[Users] How to change number of cpu cores in Ovirt 3.1 with the python sdk.
I am using Ovirt 3.1 with the ovirt-engine-sdk. I have written a python script using this sdk but I can't seem to get the parameters right to change the cpu cores when creating the vm.
