Xen Status Update Computer Laboratory Ian Pratt XenSource Inc. and University of Cambridge

3.0 Status update  3.0 Status  What works, what’s missing, what’s broken  Release criteria  Testing and more testing  Tools progression  Project infrastructure & organization  3.1 plans

Current Status x86_32x86_32px86_64 Domain 0 Domain U SMP Guests nearly Save/Restore/Migrate ~tools >4GB memory 16GB4TB VT 64-on-64 Driver Domains

Current Status x86_32x86_32px86_64IA64Power Domain 0 Domain U SMP Guests nearly Save/Restore/Migrate ~tools >4GB memory 16GB4TB ? VT 64-on-64 Driver Domains

Release Requirements  3.0-testing release reqs  x86_32/x86_32p/x86_64 passing reg tests  (save/restore/migrate excepted)  New time API  Don’t wait for XenBus  release requirements  All drivers using XenBus  Passing full regression test suite

Testing  XenTest from IBM  XenBench2  Multi domain  Benchmarking and load testing  Tools tests  Results matrix on web site  XenTestCD  Automated platform testing

3.1 Plans  Pacifica / VT-x abstraction  Improved IO Emulation  Finish tools project phase 3  Performance tuning and optimization  Less reliance on manual configuration  Infiniband / Smart NIC support  … (NUMA, Framebuffer, etc)

Project infrastructure  Mercurial flag day  Bugzilla support  Wiki  Test matrix federation  Need more developers! 

Tools Phase 1

Tools Phase 2 : 3.0.0

Tools Phase 3

Discussion topics?  Linux arch-xen preparation for upstream  Smart IO (Infiniband etc)  IA64/PPC common code changes  Pacifica / VT-x abstraction  New IO emulation model  Distro ind. guest installs (e.g. rpmstrap)  >4GB DMA  Debian packaging  SMP bad pre-emption avoidance  Virtual framebuffer support
