Description Don Dutile (Red Hat) 2011-08-31 04:10:07 UTC 
Description of problem:
Assigning a physical PCI device to a KVM guest has many subtle details which can easily go wrong for a user/admin.  Thus, adding a troubleshooting section to chapter 12 would be prudent.

So, here goes a recommended ToC:
  12.4 Troubleshooting Device Assignment
      .1 Multi-function devices (MFDs)
         .1 Security implications
         .2 hot-add versus static assignment
      .2 ACS Checking
      .3 PCI assignment (B:D.F) in guest
      .4 Potential driver issues
         .1 function-dependent addressing in MFDs
         .2 reset handling
      .5 How libvirt performs device assignment
         .1 PCI B:D.F assignment in guest
         .2 binding a device to pci-stub
         .3 reset-ing a PCI(e) device
         .4 binding device back to host

Alex,

I believe that you are the best person to own the device assignment troubleshooting guide. It is mostly between you and ddd.

Thanks, Ronen.
