I just ran into a problem I can't make heads or tails of, so I'm hoping to get some help here.

Granted the OS I'm installing is again a custom Linux with some software running on top ..so It's not a well known OS...but I'm hoping that does not matter much.
After installation I get all sorts of kernel panics and errors about services not being able to start.
So I tried the same thing on ubuntu 14.04.2 LTS which installed qemu-kvm 2.0.0 and libvirt 1.2.2
Same config xml, but this time it worked better -I was not getting the kernel panics.
The OS I'm installing does not support IDE disks, it needs a virtio disk.
The obvious solution here would be to try and get a newer version of qemu, but since we're talking about a custom built Linux I'd have to add the package manually and compile from source...which cakes a long time to do. So before attempting that....just wondering....is there a better way? Anything I can try?
