[Qemu-devel] KVM call minutes for Feb 8

[Chris Wright]

Automated builds and testing
- found broken 32-bit
- luiz suggested running against maintainer trees
- daniel gollub offered to take on maintenance
- integration with kvm-autotest?
  - lucas, daniel, stefan...
  - testing each git commit is probably overkill and too expensive
  - current autotest run (each 48-hours to batch it up)
  - stefan currently running once a day, autotest run is 3 hours, so
    daily should work
- need an integration tree to run build test on?
  - probably still too early

QEMU testing
- kvm unit tests
  - small standalone kernel that exercises paths that have shown bugs
    http://git.kernel.org/?p=virt/kvm/kvm-unit-tests.git;a=summary
- Michael Roth recent sent RFC for qtest
  (http://www.mail-archive.com/address@hidden/msg54191.html)
  - test module (->init(), ->run()) which runs in place of vcpu threads to
    set up a test framework to do targetted testing, for example, of devices
  - normal C code, access to qemu internal functions
  - not just functional device testing, but can also to fuzz testing
  - looking feedback/users/test developers/etc
- PPC (just kernel + initrd to boot, and verify boots are identical)
  - full install in many cases is too long, and can trigger other issues
    (alex had examples of emulation being slow enough that login screen
    times out)
- tcg basic testing to verify qemu-kvm patch isn't breaking tcg

Cross version migration (new->old version migration thread)
- downstreams want this, support this upstream?
- versions vs. subsections (subsections should allow this to work)
- (as usual) more vmstate conversion needed
- qdev/vmstate both examples of partially completed work that need more
  attention
