[ovirt-devel] [vdsm] what happens to ovirmgmt during new host deployment?

Hi, I sent mails to ovirt-user maillist for help. But it seems there is no useful info in vdsm.log and supervdsm.log. I want to debug the code and so ask for help here. I am using ovirt 3.6.4.1 and vdsm 4.17.24. When deploy a new host, bridge ovirtmgmt has been created with port eth0. But it fails with: Host dell12 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' I can make ovirtmgmt work by selecting the tab 'Hosts' -> node name(dell12) -> subtab 'Network Interface', click 'Setup Host Networks', drag ovirtmgmt to link with ethernet interface eth0. What engine did to bridge ovirtmgmt during new host deployment? Just call "getVdsCaps" to check whether ovirtmgmt is ready or sent setupNetwork command to configure ovirtmgmt? Which part of vdsm code should I check please? Thanks a lot. --Kai
