+Support more than 4G memory for guest with Intel HAXM acceleration
+
+setup:
+
+host: windows 7 professional 64bit
+guest: centos 7
+qemu 2.10.92
+haxm 6.2.1
+
+issue: when assign 4096M or more memory to the guest, I got following error message:
+E:\qemuvm\vm-svr>qemu-system-x86_64 -accel hax -hda centos-1.vdi -m 4096
+HAX is working and emulator runs in fast virt mode.
+Failed to allocate 0 memory

+hax_transaction_commit: Failed mapping @0x0000000100000000+0x40000000 flags 00
+VCPU shutdown request
+VCPU shutdown request
+if I change memory to 4095M, guest VM boot up without issue
+
+E:\qemuvm\vm-svr>qemu-system-x86_64 -accel hax -hda centos-1.vdi -m 4095
+HAX is working and emulator runs in fast virt mode.
+
+
+This is known limitation, I already raised a request on HAXM github site for fix this: https://github.com/intel/haxm/issues/13, and it got accepted will be fixed in next haxm release; however it seems there is also qemu side work (according to haxm dev), so I raise this for qemu side fix;
