Hi guys!

I want to upgrade my oVirt nodes from oVirt Node - 3.6 - 0.999.201607061021.el7.centos to ovirt-node-ng-installer-ovirt-4.0-2016062412. I want to use the ovirt-engine GUI for it. I already installed oVirrt-engine version 4.0 and the ovirt-node-ng-image squashfs image version 4.0.0. I don't wanna do virtual CD/DVD upgrade because is across datacenter and I'm doing right now and is to slow. On the other hand I haven't been able to use ovirt-node-upgrade tool cause I can't find any example of the parameter --iso=, so I've no idea how to use it. Not even one example in google. BTW, Thank you very much to Douglas Schilling Landgraf for the previous answer. Thanks to him I could workaround my issues..
