Hello, By following the instruction at https://www.ovirt.org/documentation/upgrade-guide/appe-Manually_Updating_Hos..., I tried to upgrade host from 4.2.8(CentOS 7.6) to 4.3.7. After the reboot, the host still running 4.2.8 vdsm. # rpm -qa | grep vdsm vdsm-common-4.20.46-1.el7.noarch vdsm-yajsonrpc-4.20.46-1.el7.noarch vdsm-hook-vhostmd-4.20.46-1.el7.noarch vdsm-4.20.46-1.el7.x86_64 vdsm-client-4.20.46-1.el7.noarch vdsm-python-4.20.46-1.el7.noarch vdsm-hook-fcoe-4.20.46-1.el7.noarch vdsm-network-4.20.46-1.el7.x86_64 vdsm-jsonrpc-4.20.46-1.el7.noarch vdsm-hook-vmfex-dev-4.20.46-1.el7.noarch vdsm-http-4.20.46-1.el7.noarch vdsm-api-4.20.46-1.el7.noarch vdsm-hook-ethtool-options-4.20.46-1.el7.noarch vdsm-hook-openstacknet-4.20.46-1.el7.noarch [root@ovs260 ~]# Looks like the upgrade did not take place as expected. Any clue? Thanks in advance, Jingjie
