So here are 3 backtraces from booting the rescue system:

To me they all look the same.

They are.  What version of qemu are you using?

latest stable-1.1 branch (1.1.1) - which works fine with latest RHEL6
kernel.

This could be due to a kernel bug, or due to a different code path taken
in qemu because of differing features exposed to kvm.

Please try qemu-kvm.git master and report.

qemu-kvm.git master just hangs after the 2nd screen with using 100% CPU
and doing nothing... so i can't test with qemu-kvm.master

Please provide your command line and I will try to reproduce.

ulimit -c unlimited; /usr/bin/qemu-x86_64 -chardev socket,id=qmp,path=/var/run/qemu-server/103.qmp,server,nowait -mon chardev=qmp,mode=control -pidfile /var/run/qemu-server/103.pid -daemonize -usbdevice tablet -name kvmcrash -smp sockets=1,cores=8 -nodefaults -boot menu=on -vga cirrus -k de -drive file=/dev/VGiSCSItarget0/vm-103-disk-1,if=none,id=drive-virtio0,aio=native,cache=none -device virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,bootindex=100 -drive file=/var/lib/vz/template/iso/ubuntu-12.04-server-amd64.iso,if=none,id=drive-ide0,media=cdrom,aio=native -device ide-cd,bus=ide.0,unit=0,drive=drive-ide0,id=ide0,bootindex=200 -m 4096 -netdev type=tap,id=net0,ifname=tap103i0,script=/var/lib/qemu-server/pve-bridge,vhost=on -device virtio-net-pci,mac=BA:5B:86:AD:14:3A,netdev=net0,bus=pci.0,addr=0x12,id=net0,bootindex=300
