[Qemu-devel] [Bug 1276879] Re: lots of dma command 10, 14 not supported

[BALATON Zoltan]

The other patch is for KVM. Here's a way to build a patched kvm module (I did 
not test it):
http://www.contrib.andrew.cmu.edu/~somlo/OSXKVM/#sec_0_kvm_kmod_build

A click in the window should be enough to grab the mouse. If it's not
working it may be that NeXTSTEP is using a different driver than what
QEMU emulates. Since NeXTSTEP is quite old you may have better luck with
a serial mouse emulation such as msmouse or make sure a PS/2 mouse
driver is selected in NeXTSTEP (it may not autodetect it).

Title:
  lots of dma command 10, 14 not supported

Status in QEMU:
  New

Bug description:
  Trying to install NeXTSTEP 3.3 onto a 2GB file with QEMU 1.7.0.
  In the terminal that started QEMU, there are a lot of
      dma: command 10 not supported
  and 
      dma: command 14 not supported
  messages.  When the installation of NeXTSTEP gets to
  'preparing disk for nextstep installation', there are a lot
  of messages that ATA command c5 failed and other info.
  The result is a failed installation.

  Is this a bug in QEMU?  Is there a workaround, e.g. by
  disabling DMA altogether?

  thank you
