		Using this config to custom the rptun ivshmem cpuname and role,
		using ";" to split the names.
		For example, if RPTUN_IVSHMEM_CPUNAME = "0:cpu1:m;1:cpu2:s" and pass
		two ivshmem devices to the qemu, we will get two rptun ivshmem
		drivers with ivshmem device match id: [0, 1],
		remote cpu names: ["cpu1", "cpu2"] and roles: ["master", "slave"']
