glad to hear.
two comments on dreyou nice post:
1. on host side, worth running 'yum update' in general, not only vdsm
(for kernel, libvirt and others).
2. the recommended way to upgrade a node is to first move it to
maintenance in the engine (which should live migrate the VMs to
other hosts). doing without this may work, but YMMV.
