      .You can now replace SPICE with VNC in the web console

      With this update, you can use the web console to replace the SPICE remote display protocol with the VNC protocol in an existing virtual machine (VM).

      Because the support for the SPICE protocol has been removed in RHEL 9, VMs that use the SPICE protocol fail to start on a RHEL 9 host. For example, RHEL 8 VMs use SPICE by default, so you must switch from SPICE to VNC for a successful migration to RHEL 9.

      Spice (server) was deprecated in RHEL8.3 and completely removed in RHEL9.
      For customers that have upgraded the system to RHEL9, any VMs configured with SPICE will fail to start, see: https://access.redhat.com/solutions/6955095

      Currently, there is no way to do this from the UI (cockpit-machines). For users that prefer the UI and/or not proficient in manual XML editing this will be a difficult and time consuming task, with potential downtime fo the VMs.

      Please implement a way for the user to configure the graphics of the VM in the UI, so the user is able to switch from SPICE to VNC and start the VMs quickly after upgrading to RHEL9 in case the graphics switch was not done before the upgrade.

      Similar request exists upstream, here: https://github.com/cockpit-project/cockpit-machines/issues/553
