creating a lxc container from scratch

So I have a tar of a chroot we use in our own provisioning system. Just a straight up tar of an OS that get pxe'd out. I'm trying to take that and use it as a template for an lxc container I'm building. When I run pct, I get:

[...]
Total bytes read: 1234728960 (1.2GiB, 107MiB/s)
Detected container architecture: amd64
unable to detect OS disribution


I've tried modifying the /etc/issue in the chroot from:
\S
Kernel \r on an \m

to:
Red Hat Enterprise Linux
Kernel 3.10.0-123.4.2.el7.x86_64 on an x86_64

to no avail. Is there any way to tell pct what distro I'm using? I'm sure this isn't exactly a supported operation, but I'm trying to wrap my head around the internals here. Obviously this is VE 4 Beta 1. command used:
pct create 101 rhel-7.x64.tar.gz -description rhel7 -disk 4 -hostname rhel7 -memory 512 -nameserver 8.8.8.8 -net0 hwaddr=52:4A:5E:26:58:D7,ip=192.168.1.3/16,gw=192.168.1.1,bridge=vmbr0 -storage rhea-proxmox -password blahblah
 
Scientific Linux release 7.1 (Nitrogen)I got a little further and messed with /usr/share/perl5/PVE/LXCSetup/Redhat.pm to allow for 7.1. I've got it starting and letting me log into the container with 'lxc-start -F --name 100', but I can't get anything going via the GUI (I can start it, the container starts, but I can't get anything at the console... It's almost like there's no entry point or something... I really don't know enough about lxc to debug further.
 
I actually got just a bit further. using lxc-start -F, I was able to wedge an ifcfg-eth0 onto the container and enable sshd, so I can confirm that starting via the gui does start the container and all networking works, but I'm still not getting any console.

Hi,
only a shot in the dark, because I'm never tried LXC yet.

Perhaps the same reason like on OpenVZ? http://pve.proxmox.com/wiki/OpenVZ_Console
