[ovirt-users] VMs unknown state and ovirt node Non Responsive

Hi. I have a simillar problem like in this link: https://access.redhat.com/discussions/1326793 https://bugzilla.redhat.com/show_bug.cgi?id=1165269 Similar, becouse I worked it out with the VM uknown status, but I still have problem with host (node). It is all in one installaltion, therefore i dont have to remove host and add again (it is only one host portal and node on the same host), because there are still connected to the VMs. It is ovirt 3.4.4 release in latest updates on Centos 6.6 (Centos 6.5 Final). Can I do smoethings or can I upgrade to ovirt 3.5 release (safely without losing anything) if this helps. If anyone would like to help me remotely (for charity), I would be grateful :) -- G.Sz.
