Hello, at this moment (about two days ago) I have updated only engine (external, not self hosted) from 4.2.7.5 to 4.2.8.2 As soon as I'm starting for the first time a VM with an ovn based nic I get what below in ovirt-provider-ovn.log In admin gui, if I try for example to start via "run once" I get: " Error while executing action Run VM once: Failed to communicate with the external provider, see log for additional details. " Any clue? Thanks, Gianluca 2019-01-29 17:23:20,554 root Starting server 2019-01-29 17:23:20,554 root Version: 1.2.18-1 2019-01-29 17:23:20,555 root Build date: 20190114151850 2019-01-29 17:23:20,555 root
