priorities can take values
0,1,2 or even 1000.
This patch removes these drawbacks and introduces a predefined set
of priorities for MemoryRegion.
This code does not affect the exisiting memory topology build process,
so does not cause any issues related to change of regions visibility.

and have exclusive priority.
Since may_overlap is abandoned, memory_region_add_subregion and
memory_region_add_subregion_common become equvalent so
memory_region_add_subregion_common is removed.

memory_region_set_priority() to change priority from the default.
This patch adds predefined priority values in memory.h. Priority can take
one of 4 possible values: low (default), medium, high and exclusive
(highest).

This patch raises the priority of the kvm-apic memory region, so it is
never pushed out by PCI devices. The patch is quite safe as it does not
touch memory manager.
I have fixed styling issues. Please use this version.

Hi all,
I had qemu 1.2.0 crash when using ivshmem driver with 64bit PCI support
enabled. The qemu process is terminated at a very early stage of
Linux boot up. Here is the qemu command line:

Hi Gerd,
Hi,
And qemu error output is:
qemu: /home/akorolev/qemu-kvm/exec.c:2255: register_subpage: Assertion
`existing-mr-subpage || existing-mr == io_mem_unassigned' failed.
Guest OS is Centos 5.5 and log is pretty boring, as qemu crashes before
Linux can report an issue.

Qemu crashes in the same way as before.

Hmm. Doesn't reproduce here (using RHEL-5 as guest, although it is 5.8
so more recent than your centos 5.5).
Is this a 32bit or 64bit guest
Hi,
It is a 64bit guest OS.
I've upgraded to RHEL 5.8 and still have the same problem.
My rhel5 is 32bit.
Could you please send me a qemu command line you are running?
