Description of problem:
With RHEV-M 3.1, changing the console type of a running VM doesn't change anything until the VM is rebooted. There is no warning dialogue indicating this, though I'd consider it a bug even if there was. Should a shutdown/restart really be required the change the console type?
Version-Release number of selected component (if applicable):
RHEV-M 3.1
Moving this over to the RHEV product.
Currently, changing the console type isn't possible on running vm, afaik. If that ability is desired, then that needs to be a feature request on all the relevant components (qemu-kvm, libvirt, rhev-m).
In the meantime, I'm moving this to the RHEV-M team so they can handle that option differently, either with a notification that the console isn't changed until the next reboot or make the option only configurable when the vm is down.
it is not possible to change the display mid-run.
however, it should be possible today to simply launch the VM with both vnc and spice, then choosing either to connect with
changing to RFE allowing to set both SPICE+VNC in VM properties. The upcoming new Display Options selection dialog (should be in 3.3) would allow you then to select one or the other.
