You did not specify the guest startup RAM size with the -m option, so the default RAM size is 128M, which is insufficient. For ubuntu-16.04.2-desktop-amd64.iso, the minimum size that works is -m 277. To be safe, add -m 512 to the qemu-system-x86_64 options, it should solve this problem.

This causes a lot of operating systems to not load, so use -m 1G (if you can spare) to be safe

I had this problem, or something very similar. It gave the same warning and, while it would then boot, it was unusably slow.
I fixed it it by adding -machine ubuntu,accel=kvm to the qemu-system-x86_64 command line.

I had this problem, or something very similar. It gave the same warning and, while it would then boot, it was unusably slow.
I fixed it it by adding -machine ubuntu,accel=kvm to the qemu-system-x86_64 command line.
