Very long reboot times of "RH" hosts with oVirt installed
I was just wondering if anyone else is experiencing the following issue. On both real physical machines and on VM when I have installed a RH derivative like CentOS, CentOS Stream, Rocky Linux or Alma Linux the reboot times are initially normal. After installation of oVirt and all the dependencies the reboot (shutdown) increases to anywhere between 3 and 5 minutes. During shutdown a blinking cursor is visible in the upper left corner. If sitting at the console E.g. for

Is it safe to mask wdmd.service on normal hosts? Can the reboot times be decreased on hosted engine hosts without breaking HA? BR Peter
Are you making sure to reboot the hosts via the oVirt engine? What I tend to do is put the host into maintenance mode, login and reboot it, once I know it's up I take it out of maintenance mode. It's not good to reboot a host while it's active from its terminal you will have issues/risks with services not stopping, so you need to do it from the engine or by putting it into maintenance mode first. I've had issues with the engine detecting the host is back up after a reboot and taking ages, so I tend to stick them into maintenance mode and reboot from the terminal. Otherwise no, it reboots normally for me.
