When? When you try to connect with virsh?

Note that you need to create a temporary password with:
hosted-engine --add-console-password

iirc 'console' connects you to the serial console, not vnc, no?

How exactly?

You need to connect to the host where it runs.

BTW, do you have there other VMs? If you migrated the engine vm there
after you already had other VMs, it will not get console '0' but some
other.

Sorry, no idea.

Please try getting some more info from the vnc client.
I personally use tightvnc on linux and verified that it can connect to
a hosted-engine console.

I am also changing the subject to attract others...
