I run the guest till OS loads and create a snapshot with savevm, then close qemu, run it again and try to load the snapshot with loadvm. The guest crashes or freezes.

I found hax_arch_get_registers function which reads registers from Haxm and is called from a synchronization procedure. I placed a breakpoint on it, ran qemu and found that it is hit one time during guest OS boot. Exactly these registers where saved in the snapshot. \ No newline at end of file |
