Hmm, interesting.
FWIW, I was able to successfully migrate L2 guest to the destination L1 guest
(hypervisor). My full QEMU command-lines for both L1s and L2 are here:
https://kashyapc.fedorapeople.org/virt/Migrate-a-nested-guest-08Feb2018.txt
With the below versions:
L0:
$ uname -r; qemu-system-x86_64 --version; rpm -q libvirt-daemon-kvm
4.13.13-300.fc27.x86_64+debug
QEMU emulator version 2.11.0(qemu-2.11.0-4.fc27)

libvirt-daemon-kvm-3.10.0-2.fc27.x86_64
On both source and destination L1s:
$ uname -r; qemu-system-x86_64 --version; rpm -q libvirt-daemon-kvm
4.14.16-200.fc26.x86_64
QEMU emulator version 2.10.0(qemu-2.10.0-4.fc26)
