[CentOS-virt] Buffered console with kvm ?

My Centos 6 server acts as a KVM host for a number of guests. Each of these guests have been configured with a serial console so I can do things like virsh console test2 and get access to the console of that machine.

However what would be really useful is if the console also had a "buffer" so that messages which appeared while I wasn't connected could still be seen (much in the way old-style serial-port terminal servers would buffer output).

Is this possible, "natively" ?

Otherwise I was thinking of doing something like running 'screen -d -m -S test2 virsh console test2' and then I can connect with "screen"

But that doesn't feel as friendly.

Any ideasor recommendations?
