Description of problem: For F10 paravirt guests on rhel 5.3 dom0, the console of the guests are accessible with virsh console but aren't accessible on virt-viewer. F10 guests seem to have hvcX as their console rather than xvc0. Version-Release number of selected component (if applicable): RHEL 5.3 dom0, F10 guest How reproducible: Very. Steps to Reproduce: 1. Install a F10 PV guest with nographics. 2. Open virt-manager, start the guest and open the console 3. Nothing will be displayed on virt-viewer console. Additional info: F10 guests seem to have hvcX as their console rather than xvc0.
hvcXXX is a paravirt text based console. virt-viewer displays the graphical console. If the guest OS is configured to only output on its text console, there's nothing for virt-viewer to display. To make it visible in virt-viewer you need to make your guest use the graphical console for its output.
