My current implementation is less than 100 lines of network-facing code (using ICMP payloads, but the same could be achieved with UDP), though that increases to about 300 if you count in the SHA-1 implementation that I am using for verifying customer credentials. So 300 lines is for a complete solution including crypto and accounting/payment.


That's certainly interesting. Are you using ICMP simply for high-level management or are you passing event channel messages via ICMP? Are you just punting issues of reliability?

I agree with you, TCP is not the only network solution. However, it seems logically that a large number of people will want a TCP solution :-)


I am using TCP, but I am doing both bootstrap+shutdown of new domains, migration, and accounting mostly within domUs. I send an ICMP payload with an initial ticket/capability describing the max memory, disk extents, external IP etc., and the ICMP server in dom0 decodes/verifies that, an fires up a domU with a minimal TPC/IP stack and server inside. The domain builder is then uploaded on that connection, takes over, and handles the bootstrap from there. Same is true for migration.
