[Pkg-libvirt-maintainers] Bug#494831: I think I ran into this

[Peter Palfrader]

# this really deserves grave, but I'd rather have it fixed than argued about
severity 494831 important
thanks

My kvm/qemu domain has the following output defined via libvirt:

sookie:~# cat /etc/libvirt/qemu/test.xml 
...
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target port='0'/>
    </console>

and I have the kernel console redirected to ttyS0, so kernel log
messages end up on the pty there.

After some kernel action, say mounting a few filesystem, iptables
logging etc, some internal buffer runs over and the entire domain
freezes up.

That is, until I look at the console using 'virsh console test'.  Then I
get all the backlog spewn at me and stuff continues.

This really really needs to get fixed.
