[Bug 1519917] Re: [Hyper-V] Rebase Hyper-V to 4.3 kernel

 

Functional test run complete and we got expected storage I/O
performance.

The known issues are still present: IP injection does not work (bug
1506521), Copy-VMFile timeout at ~2GB.

However, it appears that kdump is broken again (this had been resolved
in the Oct 10 Wily build). I suspect that since kdump is also broken in
linux-next testing (see bug 1515301) this is not because of your kernel
in particular.

Title:
  [Hyper-V] Rebase Hyper-V to 4.3 kernel

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Wily:
  In Progress

Bug description:
  Please rebase Hyper-V support to the final upstream 4.3 kernel.

  The following files and directories contain Hyper-V support:
  arch/x86/include/asm/mshyperv.h
  arch/x86/include/uapi/asm/hyperv.h
  arch/x86/kernel/cpu/mshyperv.c
  drivers/hid/hid-hyperv.c
  drivers/hv/
  drivers/input/serio/hyperv-keyboard.c
  drivers/net/hyperv/
  drivers/scsi/storvsc_drv.c
  drivers/video/hyperv_fb.c
  include/linux/hyperv.h
  tools/hv/

  There are, of course, a number of sauce items already present in
  Ubuntu to keep. Please add the following additional sauce item for
  networking performance [attached].

  This rebase request is intended for wily/15.10. We should investigate
  it's applicability to vivid/15.04 and HWE kernels as well. Because
  14.04's HWE kernel will change to wily in January, 15.10 may be
  sufficient in the long term. Thank you!
