Testing with both vhost-user-gpu-pcu and vhost-user-vga, the memory_isolation property is getting properly set in vhost_user without adding an alias. In both cases, dev->vdev refers to a VhostUserGpu, which has the memory_isolation qdev property set as in other vhost-user front-ends. Unlike most vhost-user front-ends, vhost-user-gpu does not define a "chardev" qdev property. Maybe that is why the "chardev" property needs to be aliased? However, I don't understand why "chardev" is not a qdev property as vhost-user-gpu already makes use of many of them. Best, Connor
