From: Anthony Liguori <aligu...@amazon.com>
Only print the banner if the log threshold is at least info.
For Vixen guests, we want the console output to be exactly what the
PV guest would show on it's own. That means the inner Xen banner
can potentially break automation that assumes a specific type of
console output.
