Hi!
I'm testing CS with Ubuntu 22.04 LTS that uses libvirt 8.0.0-1ubuntu6
(using CS repository from focal 20.04). After all the installation process,
when the manager tries to start some system VMs (like SSVM), the hypervisor
hosts can't do that. In the agent logs I can see:
2022-04-08 16:17:30,142 WARN [resource.wrapper.LibvirtStartCommandWrapper]

In the libvirt logs I can see:

Looking for something about that I realized that older versions of libvirt
could just ignore VNC passwords bigger than 8 chars. Now it looks like an
error is triggered.
I tried to find where CS stores the .xml file for the SSVM domain to see if
the password is really a 22 chars password, but I didn't find it.
I think the problem is when generating the .xml file for the new domains.
Probably CS generates a long password.
Is there any way to configure the size of VNC password that CS generates?
Thank you!
