Hey Jim,
I'm on libvirt.git's trunk and I see the following:
[xen@ghoul3 libvirt.git]$ sudo ./tools/virsh list
Id Name State
----------------------------------------------------
3 debian_32 running
4 fedora20_64 running
[xen@ghoul3 libvirt.git]$ sudo ./tools/virsh console debian_32
Connected to domain debian_32
Escape character is ^]
error: internal error: cannot find character device (null)
[xen@ghoul3 libvirt.git]$ sudo ./tools/virsh console fedora20_64
Connected to domain fedora20_64
Escape character is ^]
error: internal error: cannot find character device (null)
And this:
[xen@ghoul3 libvirt.git]$ sudo ./daemon/libvirtd -v
[sudo] password for xen:
2013-12-17 13:19:35.366+0000: 22124: info : libvirt version: 1.2.1
2013-12-17 14:00:06.587+0000: 22122: error : libxlDomainOpenConsole:3885 : internal error:

2013-12-17 14:00:15.705+0000: 22125: error : libxlDomainOpenConsole:3885 : internal error:

What I have in /var/log/libvirt/libxl does not look useful, while below
it comes my xenstore-ls.
What is it that is going wrong?
