panic device is a device that enables libvirt to receive notification of
guest panic event. qemu implements it by pvpanic. This series adds support
for panic device. It is implemented in qemu driver only.
changes in v3:
- introduce generic ISA address
- rename pvpanic to panic.
- add RNG schemas for new elements
- add tests for panic device
- error out if panic device is requested but qemu is too old
Hu Tao (4):
conf: introduce generic ISA address
conf: add support for panic device
qemu: add support for -device pvpanic
test: add test for panic device

has no checks for !src && !dst
I'll put together a patch for this, but figured I'd ask now if there were
checks that should also be made in the PanicCheck API...

Yay for automated regression testing catching something! And sorry that
I missed this in my initial review. Yes, adding or removing the panic
device is an ABI incompatibility.

Not really - a panic device has only two properties: existence, and
address (the existence check is missing, which caused the core; but the
address check is already there).

device is an ABI incompatibility.
Indeed. The ABI stability checks are something we really ought to
be able to have our unit tests do in fact. At the very least we
could feed in every single XML file we have in the test suite as
both the src & dst params, to serve as an "identity" test.
