We are trying to do VM Migration using the version of Qemu obtained from the following branch:


And we are also using Linux Kernel 3.16 compiled with the patches for AArch64 migration support obtained from the following link:


We have tried both online and offline migration. However, we end up getting the following error at runtime during migration:

qemu-system-aarch64: Unknown combination of migration flags: 0

qemu: warning: error while loading state section id 3

qemu-system-aarch64: load of migration failed: Input/output error

Could anyone please suggest on this.
