Full dmesg output captured from the VM
NOTE: dmesg output was captured after invoking libguestfs-test-tool which resulted in the Kernel panic.

dmesg output from physical host
I forgot to note this is in a nested environment.
Host is running RHEL7 (beta). Here's the versions:
$ uname -r; rpm -q libvirt-daemon-kvm qemu-kvm-rhev
3.10.0-52.el7.x86_64
libvirt-daemon-kvm-1.1.1-12.el7.x86_64
qemu-kvm-rhev-1.5.3-19.el7.x86_64
This patch fixes it: https://patchwork.kernel.org/patch/3421271/ I re-built the Kernel on L0 (physical host) and L1 (guest hypervisor) with the above patch, and re-ran the libguestfs-test-tool, which invokes an L2 KVM guest -- it now successfully boots. Created attachment 120401 [details]
