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.

Pankaj Rawat

Without knowing anything about your setup, I'd guess you have no getty
running.
