Hi there,
I have tried to restart the Hosted Engine but I cannot ssh/ping the Hosted Engine after
the restart. The oVirt webUI was down and I cannot start the VM in both GUI and CLI.
I have used command "hosted-engine --console" to start a console but error
message "Cannot find character device <null>" was prompted.
I also checked the status of the Hosted Engine and the its state was
"EngineStarting". However, the Hosted Engine will keep restarting in the same
host automatically.
Please help
1. Is there any commands that I can use to start the VM inside the Hosted Engine CLI.
2. Does anyone know why my Hosted Engine cannot be started successfully and accessed via
CLI.
Thank you for your help.

Hi,
You might be able to get VNC console through virsh, if you have configured
sasl auth with libvirt.
Then you could try to start the engine VM paused:
hosted-engine --vm-start-paused
then add a VNC password:
hosted-engine --add-console-password
Then try to connect with vnc and you may resume the VM:
virsh -c qemu://hostname.local/system resume HostedEngine
where hostname.local is the hostname part of the connection URI.
You might also get some insight from host logs (vdsm.log).
In my case, 99% of the cases was a storage issue that was causing engine to
not be able to boot.

Hi Alex,
Thanks for your help.
However, I reduced the size of the /run/user/0 (i.e. /tmp) in the Hosted Engine and now I
cannot connect/ping the Hosted Engine. All the service of the Hosted Engine was down.
Do you have any idea on how to fix this problem? Thank you.
