It might also be helpful to configure the kvm in a way to have a 2nd console
redirected into a file

e.g. add

<console type='file'>
<source path='/var/log/guest.log' append='on'/>
<target type='sclplm' port='1'/>
</console>

to the libvirt xml to also have the line mode console (and then redirected to a
file).

Inside the guest you should add
console=ttyS0 console=ttyS1
to the kernel command line to get kernel messages on both consoles.

kernel loglevel on the kernel command line would be
loglevel=7
(see Documentation/admin-guide/kernel-parameters.txt)

Can you check the host dmesg for any error messages (or
/var/log/libvirt/qemu/xxx.log ?
