[libvirt] 0.9.7 virsh console regression?

[Albert W. Hopkins]

Hi folks,

I have a few "headless" qemu domains that use serial consoles.
Typically i connect to the consoles with

        # virsh console <domain>

However with 0.9.7 I get

        Connected to domain gentoo-base
        Escape character is ^]
        error: internal error character device (null) is not using a PTY

I am still able to connect to the console if i go into the virt-manager
gui and use the "gui" console, but I'd rather not do that as sometimes I
don't have access to the gui.

Is this a regression or am I expected to do some kind of migration on my
domains.  These are qemu guests running on Gentoo Linux.  An xml dump of
a typical domain follows:
