KVM test: unattended_install.py style changes
- Use vm.verify_alive() instead of vm.is_alive().
- Use error.context() so that if verify_alive() fails the resulting
error
message will be clearer.
- Make the code a little bit shorter.
- Catch VMAddressError (can be raised by vm.get_address()).
- Use double quotes for consistency.
- Modify debug messages.
Changes from v2:
- Re-added the decorator error.context_aware
Changes from v1:
- Rebase against latest upstream
