Scenario:- The host is fedora17 Libvirt:0.9.11 And guest is rhel6.2, fedora17 The Host is running on a Intel I5 processor Our xml file contain entry for 1 serial console , 2 virtio console The xml file get properly defined, and proper port assigned to each console Now when guest is started. I am not able to connect via virtio console #virsh console --devname console1 guest My console get stuck , I am not getting any prompt. #virsh console guest It works fine but it connect to guest via serial console , not by virtion console. Now in guest I look for the virtio_console driver which I found is not loaded, also not separate getty started for any virtio console When I manually load the virtio console , even then I am not able to login using the virtio console
From http://libvirt.org/formatdomain.html#elementCharChannel A virtio console device is exposed in the guest as /dev/hvc[0-7]
But /dev/hvc0 .. are already present. What does above mean? Is something special needed to be done. Does we have to even modify guest to support multiple console, Instead of modifying just the guest xml.

Hi ,
I installed fedora17 on my system, the libvirt version is 0.9.11
I configured guest.xml as specified <console type='pty'> <target type='virtio'/> </console> <console type='pty'> <target type='virtio'/> </console>
When I define the guest xml I can see the port assigned to it
Now when I try to access the console via #virsh console --devname console0 guest Or #virsh console --devname console1 guest My console get stuck , I am not getting any prompt. Is something I am missing?
Without knowing anything about your setup, I'd guess you have no getty running. Dave

Well I tried it but it doesnt work

All above are merged into one <console type='pty'> <target type='virtio' port='0'/> </console>
When I define the guest xml
Hmm, what version of libvirt do you have ? This behaviour suggest that your version is too old to support multiple consoles.
Following error received when I tried to execute the command
# virsh console --device console1 serial error: command 'console' doesn't support option --device
Doh, I mean --devname
