RPC 'os_export'
The 'os_export' RPC is used to export an OS to a compressed tarball.The path to this tarball will be given to the metadata daemon, whichwill then be used to serve this package to the instances via theinstance communication mechanism.

Add file info RPC call
Due to the need to determine the size of the temporary disk used forthe VM helper, an RPC call capable of supplying this information hasbeen added. It can be extended as needed to supply additionalinformation provided by Python's os.stat....
Use RPC transport to pass OS params to the metadata daemon
Add 'force_variant' to RPC 'os_validate'
Move function 'CheckOSVariant' to the node and add parameter'force_variant' to RPC 'os_validate', thus making the node verify theOS variant together with the rest of the OS params.
Extend '_DumpDevice' to enable/disable file truncation
... because when the data source is infinite, truncation is notnecessary, but when the data source is finite and is, for example,smaller than the device, truncation can reduce the disk size.
Fix disk truncation in download and dump OS images
Check if OS image exists on the node before dumping
Helper function to image a device by downloading or dumping
