Is OVMF too Slow for Serverless Confidential Computing?

Explore the performance implications of OVMF in serverless confidential computing environments in this KVM Forum talk. Examine recent research findings on SEV and SNP guest boot overheads, learn proper OVMF benchmarking techniques, and analyze the sources of confidential computing-related overhead. Investigate whether hardware requirements, firmware design, or implementation errors contribute to performance issues. Evaluate potential solutions, including alternative firmware layouts and boot schemes like IGVM and SVSM, to determine their effectiveness in addressing these challenges.
