I am using QEMU to create a virtualized local development environment of sorts. Right now, I have a VM running (via QEMU) with a single display (-display vnc=localhost:0 -device virtio-vga,xres=1366,yres=768). I am hoping to add a second display to the VM so that I can do something like vncviewer localhost:5900 to interact with a main (virtual) display and vncviewer localhost:5901 to interact with a secondary (virtual) display.
I have not found the right Google search incantation to produce this answer for me, nor have I found the right corner of QEMU docs that answers my question. Chat bots have been helpful, but they have started lying to me once I get into the nitty gritty details of QEMU flags.
I am wondering if anyone has any recommendations for what I should try next? Or perhaps references to prior art?
