Title:
Support more than 4G memory for guest with Intel HAXM acceleration
Status in QEMU:
Fix Released
Bug description:
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

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;
