I run qemu (version 0.9.1 kvm-84) with -serial option as follows:
- serial telnet::2445,server
so I can telnet to 2445 and have a serial console.
I tried specifying this to libvirt (version 0.6.0) using the following stanza:
<serial type='tcp'>
<source mode="bind" host="127.0.0.1" service="2445"/>
<protocol type="telnet"/>
<target port="1"/>
</serial>
I checked /var/log/libvirt/qemu/<guest>.log and found that libvirt
added 'nowait' to the serial option:
-serial telnet:127.0.0.1:2445,server,nowait
which is fine (I think).
But when I start my guest, and "telnet 127.0.0.1 2445" I don't get any
output even though the guest boots up fine. After the guest boots
$ echo foo > /dev/ttyS0
in the guest shows the 'foo' in the telnet window. But I don't get the
boot/shutdown messages.
I also have the vnc option in the xml,
<graphics type='vnc' port='5902' autoport='no' listen='127.0.0.1'/>
so if I open vncviewer, I can see the boot messages. The problem with this
though is if the kernel fails to boot for some reason, the vncviewer exits
and I can't find the reason the boot failed.
My kernel boot command line has 'console=ttyS0' option. Is there anything
else I need to ensure 'telnet 127.0.0.1 port' displays the messages ?
Thanks,
Sukadev
