Thanks X-point!...Seems TPMs are a part of Xen Architecture
Another slide covers Xen Architectural's Advantages -
Xen's true hypervisor architecture enables
excellent security and scalability
• Lightweight service domains
- I/O driver domains and utility domains
- Device emulation domains
- Domain building / measurement domains
• Allows efficient large SMP scalability
• Minimum privilege, small TCB
- De-privilege and disaggregate domain 0
True hypervisor design
- Small privileged component, principle of least privilege
• Secure compartmentalization
- Grant tables allow controlled sharing
• Optimized as a hypervisor
• Cross-platform: x86, ia64, Power and ARM
• OS agnostic: Windows, Linux, Solaris, *BSD
• Flexible to enable domain0 disaggregation
- Control-plane OS (e.g. OpenBSD or MiniOS)
- Driver domains
- Service domains (e.g. virus scanners, firewalls etc)
Ian briefly covers the Xen Project Roadmap as well -
Server
- Performance and scalability optimizations
- Enable Smart IO devices
- SCSI pass-through
• Security
- Domain0 disaggregation; XSM Xen Security Modules
- Secure boot, TPM, certification, multi-level secure systems
• Client
- Power management
Suspend and hibernate; Clock management
- 3D video
direct h/w access; high-performance guest virtualization
- USB device pass-through
