[Qemu-devel] [PATCH] Fix guest OS hangs on boot when 64bit PCI BAR present

2013-02-12 Thread Alexey Korolev
At the moment may_overlap flag of MemoryRegion structure is ignored by the address range assignment process. This may lead to guest OS hangs if critical qemu resources are overlapped by PCI BARs. For example ivshmem 64bit PCI BAR may overlap kvm-apic-msi under certain conditions. This patch adds a
