Hi all,
I'm using websockify + noVNC for expose the vm console via browser getting the
graphicsconsoles ticket via API. Everything works fine for every other host that I have
(more than 200), the console works either via oVirt engine and via browser) but just for a
single host (CentOS Stream release 8, oVirt 4.4.9) the console works only via engine but
when I try the connection via browser I get the following error (vdsm log of the host):
ERROR FINISH updateDevice error=unsupported configuration: VNC password is 12 characters
long, only 8 permitted
Traceback (most recent call last):

libvirt.libvirtError: unsupported configuration: VNC password is 12 characters long, only

The error is pretty much self explanatory but, I can't manage to figure out why only
on this server and I wonder if I can set the length of the generated vnc password
somewhere.
Thank you for your time,
Francesco
