[ovirt-users] Upgrade hyperconverged self-hosted ovirt from 4.3 to 4.4

Hi, has anyone attempted an upgrade from 4.3 to 4.4 in a hyperconverged self-hosted setup? The posted guidelines seem a bit contradictive and not complete. Has anyone tried it and could share his experiences? I am currently having problems when deploying the hosted engine and restoring. The host becomes unresponsive and has hung tasks. Kind regards, Ralf
