[cloud] Add ability to retrieve Google Compute Engine metadata For some unspecified "security" reason, the Google Compute Engine metadata server will refuse any requests that do not include the non-standard HTTP header "Metadata-Flavor: Google". Attempt to autodetect such requests (by comparing the hostname against "metadata.google.internal"), and add the "Metadata-Flavor: Google" header if applicable. Enable this feature in the CONFIG=cloud build, and include a sample embedded script allowing iPXE to boot from a script configured as metadata via e.g. # Create shared boot image make bin/ipxe.usb CONFIG=cloud EMBED=config/cloud/gce.ipxe # Configure per-instance boot script gcloud compute instances add-metadata <instance> \ --metadata-from-file ipxeboot=boot.ipxe Signed-off-by: Michael Brown <mcb30@ipxe.org> 2017-01-23 14:41:22 +00:00			`#!ipxe`

[cloud] Show CPU vendor and model in example cloud boot scripts Some problems arise only when running on a specific CPU type (e.g. non-functional timer interrupts as observed in Azure AMD instances). Include the CPU vendor and model within the sample cloud boot scripts, to assist in debugging such problems.
