Verify KVM Guest Boots Fails with traceback

[Michael Reed]

Currently this test case fails when running within the canonical-certification-server framework. However when I run this test manually it passes.

When I run the following command it passes.

sudo qemu-system-aarch64 -m 1024 -display none -nographic -net nic -net user,net=10.0.0.0/8,host=10.0.0.1,hostfwd=tcp::2222-:22 -cpu host -enable-kvm -machine virt,gic_version=host -kernel /boot/vmlinuz -initrd /boot/initrd.img -drive file=xenial-server-cloudimg-arm64.img,if=none,id=disk.0 -device virtio-blk-device,drive=disk.0 -drive file=seed.iso,if=none,id=disk.1 -device virtio-blk-device,drive=disk.1 -append "console=ttyAMA0 earlyprintk=serial ro rootfstype=ext4 root=LABEL=cloudimg-rootfs rootdelay=10"

I saw the same issue when I tried using the dev ppa (ppa:checkbox-dev/ppa)

0.31.0~rc2+201701301956~ubuntu16.04.1

Ok... not sure why this broke, then again I'm not entirely sure how these changes got into the script, I removed them...

So since they kept coming back (I "think" these are the ones that were mistakenly added in before), I'll just go ahead and complete them...

The issue was that some changes broke the data being passed to urllib to grab the image from the server.

I have a fix, testing it now.

FWIW, this is not just ARM64... something updated and broke the script across the board. Fixes in the link branch work on AMD64 and should also work on ARM and Power.
