Unbreak MIPS Malta

[PATCH 0/3] Unbreak MIPS Malta

Posted by Lubomir Rintel 2 years, 3 months ago

My day started like this:

  # virt-install --connect qemu:///system --arch mips --machine malta --memory 256 --disk none --import
  Using default --name vm-mips
  
  Starting install...
  ERROR    XML error: No PCI buses available

Needless to say, it ended up completely ruined.

Chained to this message are the patches I've created in an attempt to
remedy the highly unfortunate situation, with hope that they'll be
treated with warmth, understanding and perhaps even applied to the
libvirt tree.

Yours,
Lubo

Hi Lubo, after these patches was the VM usefully usable, did this simply
start up?

There is effectively no qemu-system-mips* mips coverage in virt-install
or libvirt unit test suites, we should add some if we don't want this to
regress. If the XML virt-install generates for you is useful, we could
drop it into libvirt's qemuxml2argvtest

Thanks,
Cole
