Hi Milan, thank you for your answer. So there is no other way/workaround? We must wait the fix in the engine and then upgrade? Maybe a downgrade of libvirt(?). I was looking up some config file in the host under /etc/libvirt and found the parameters vnc_password in qemu.conf file. I'm not sure that setting a password per host in this config file works, casue it is still passed via xml...
The default VNC password. Only 8 bytes are significant for # VNC passwords. This parameter is only used if the per-domain # XML config does not already provide a password.

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): File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 124, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 372, in updateDevice return self.vm.updateDevice(params) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 3389, in updateDevice return self._updateGraphicsDevice(params) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 3365, in _updateGraphicsDevice params['params'] File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5169, in _setTicketForGraphicDev self._dom.updateDeviceFlags(xmlutils.tostring(graphics), 0) File "/usr/lib/python3.6/site-packages/vdsm/virt/virdomain.py", line 101, in f ret = attr(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 3244, in updateDeviceFlags raise libvirtError('virDomainUpdateDeviceFlags() failed') libvirt.libvirtError: unsupported configuration: VNC password is 12 characters long, only 8 permitted
The error is pretty much self explanatory but, I can't manage to figure out why only on this server Hi,
this happens with libvirt 8.0.
and I wonder if I can set the length of the generated vnc password somewhere. I don't think so, it must be fixed in Engine. See https://github.com/oVirt/ovirt-engine/commit/a1e7e39348550b575f1f01b701105f9... for more details.
