Hi Julien, i already did that. localadmin is the user i also use for the xo-server. did not elaborate that further on a test system.

oh thank you, did not see that

ok, logged into linux, su root, and tried the command on the console mount -t nfs 192.168.30.60:/mnt/Brutus/Remote /run/xo-server/mounts/86109d77-9600-48c6-b131-0ca475cd1ad4 -o vers=3 mount.nfs: requested NFS version or transport protocol is not supported tried without -o vers=3 and it worked.

Answered on Github.

thank you, that did it. i got the container plugin installed, shows the containers in the VM fine in XO, testing migration of that VM now

Tested with Chrome now, on chrome it works. So it seems only a firefox problem. I switched off the extensions ( https everywhere, ublock origin and privacy badger ) but still crashes. Had htop running on my client while crashing, no unusual increase in RAM usage while going to crash. Rebooted XO VM, now it is ok again with firefox. so for me the issue is closed, if somebody is bored and wants to look into some logs for bug hunting i am glad to provide them. i also restarted the toolstack on one of the pool members ( not master ) and the "no such host" error is gone.
