I have created 4 world in arm fvp realm, secure, non-secure and root. In non secure linux is running as host. I have created one realm guest vm (virtual machine) here i can able to communicate from realm guest vm to host but not from host to realm guest vm, want to communicate or ping the ip from host to guest vm. Is there any solution

Tried creating 4 world in arm fvp realm, secure, non-secure and root. One guest realm vm is created, expecting to communicate from non secure to guest realm vm and vise versa
