[Qemu-devel] [PATCH RFC v2 06/12] VMState test: hmp interface for vmstate testing

[Sanidhya Kashyap <sanidhya.iiith@gmail.com>]

I have added the hmp interface for vmstate testing. Currently, the patch does
not support the qdev list, since I could not figure out how to the pass the
VMStatesQdevDevices struct which can be parsed and used.
