Unable to revive host after a reboot
by Julius Schwartzenberg 03 Aug '18

03 Aug '18

Hi, I recently had to shutdown my oVirt system which contains both the engine and the host. After it came back up, the host was not able to initialize anymore from the oVirt UI. First it kept getting stuck in a loop with setting "ExecutingStarted: Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode." This was being repeated over and over again. It also gave this error: Host pc331 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' Even though I am using that interface (ovirtmgmt) to access the system and 'ip addr show' shows that it's set up properly. I tried some more things, including upgrading the host, When I do that, the status changes to 'Installing' and later to 'Install Failed'. Here are the engine.log, vdsm.log and ovirt-host-deploy*.log: https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI https://drive.google.com/open?id=10Zm2dDpxM2k5A2bEs_l6gOv_yWv4cjlN https://drive.google.com/open?id=1AieWMzRuA0gZj3x5yDH1AGnsT2E3VtOM Any idea what is going wrong (what I'm doing wrong) and how to solve it? Thanks in advance! Best regards, Julius

Possible to use Console via Mac web browser?
by Jayme 03 Aug '18

03 Aug '18

I recall in the past (on a bit older of an oVirt build) I was able to launch VM consoles from my web browser. I believe it may have been using spice html5 at the time, is this still possible? Currently launching console downloads the typical .vv file. What is currently the best/easiest method to access VM consoles using MacOS?
