Review of ACTIONS

• MSI-X issue: Patch has been committed
• Handling of functional degradation: James to work with his team to evaluate previous instances of such issues and propose specific solutions/patches to enable this to be done differently going forward
  • James not on the call, leave until next time.
  • Clarification by mail: more urgent things have pre-empted it.
• 4.3 Release (PVH status)
  • Konrad updated George re status
  • Mukesh should be reposting by the end of the week
  • Was relying a bit on slip due to event channels to give breathing space.
  • ACTION: Konrad to follow up with Mukesh + raise the possibility of a slip on list.

• Event Channel Scalability:
  • Citrix platform team (Wei) have resumed work on the 3 level stuff
    • Favour the existing code over the proposed but unimplemented alternative for 4.3
    • Core stuff is ok, mostly discussion of config option names etc (probably not an issue for the freeze)
  • James not on call so no news RE XenServer team and QUEUE/FIFO model resourcing.
  • Clarification by mail: We're spinning up an internal project to reserve resource for this. I'll update after our resourcing meeting next week.

Current technical challenges

• AMD are investigating a performance regression of WinXP as a guest
  • Discussion has been on list
  • Time seems to run at half speed for the guest
  • Probably also an issue in 4.2
  • A changeset has been fingered but it is hard to see why this affects time.
  • Investigation ongoing, this is a high priority for AMD.

Coordination on current and future work

None

Next call

Konrad volunteered to send out the Agenda for next time in my absence. Thanks Konrad!
