Multiple PHBs are important on Power virtual machines because it allows EEH to work correctly for multiple devices. If a virtual machine has only one vPHB and an EEH occurs to an adapter passed through to the virtual machine and attached to that vPHB, all other adapters connected to the same vPHB will be reset because of the EEH recovery routine. With multiple vPHBs we can attach one device per PHB and EEH will work independently without problems for each adapter. This feature has already been integrated upstream and will be available with libvirt 3.6.0. QEMU already allows multiple PHBs. This feature is to add this support into libvirt.
