acpi,pci,pc,virtio fixes and enhancements
This includes new unit-tests for acpi by Marcel, hotplug for pci bridges by myself (piix only so far) and cpu hotplug for q35. And a bunch of fixes all over the place as usual. I included the patch to fix memory alignment for q35 as well - even though it limits 32 bit guests to 3G (they previously could address more memory with PAE). To remove the limit, this will have to be fixed in seabios. I also added self as virtio co-maintainer so I don't need to troll the list for patches to review. Signed-off-by: Michael S.

"""Extract guest vmcore from qemu process coredump.
|
||||||
|
|
||||||
|
The sole argument is FILE, identifying the target file to write the
|
||||||
|
guest vmcore to.
|
||||||
|
|
||||||
|
This GDB command reimplements the dump-guest-memory QMP command in
|
||||||
|
python, using the representation of guest memory as captured in the qemu
|
||||||
|
coredump. The qemu process that has been dumped must have had the
|
||||||
|
command line option "-machine dump-guest-core=on".
|
||||||
|
|
||||||
|
For simplicity, the "paging", "begin" and "end" parameters of the QMP
|
||||||
|
command are not supported -- no attempt is made to get the guest's
|
||||||
|
internal paging structures (ie. paging=false is hard-wired), and guest
|
||||||
|
memory is always fully dumped.
|
||||||
|
|
||||||
|
Only x86_64 guests are supported.
|
||||||
|
|
||||||
|
The CORE/NT_PRSTATUS and QEMU notes (that is, the VCPUs' statuses) are
|
||||||
|
not written to the vmcore. Preparing these would require context that is
|
||||||
|
only present in the KVM host kernel module when the guest is alive. A
|
||||||
|
