virtio-9p: Introduces an option to specify the security model.
The new option is: -fsdev fstype,id=myid,path=/share_path/,security_model=[mapped|passthrough] -virtfs fstype,path=/share_path/,security_model=[mapped|passthrough],mnt_tag=tag In the case of mapped security model, files are created with QEMU user credentials and the client-user's credentials are saved in extended attributes. Whereas in the case of passthrough security model, files on the filesystem are directly created with client-user's credentials.
