Bit Definition
--------------
bit 0: a guest panic has happened and should be processed by the host
bit 1: a guest panic has happened and will be handled by the guest;
the host should record it or report it, but should not affect
the execution of the guest.

PCI Interface
-------------
The PCI interface is similar to the ISA interface except that it uses an MMIO
address space provided by its BAR0, 1 byte long. Any machine with a PCI bus
can enable a pvpanic device by adding '-device pvpanic-pci' to the command
can enable a pvpanic device by adding ``-device pvpanic-pci`` to the command
line.
