Hi, one probably really wants to use libvirt rather than qemu directly. That way you can create your VMs remotely with a GUI (virt-manager) using a ssh-based libvirt url, or a CLI (virsh) and it will handle all the right parameters for qemu, the required networking setup, etc. Check it out !

as @wmf correctly stated "If the OP was running a virtual desktop on a server with no GPU then they probably had to fall back to software rendering which can be slow. This isn't QEMU's fault per se; if you physically don't have a GPU then you don't have a GPU."

and 99% cheap servers in the wild dont have a GPU or even hardware graphic card

yes, i connect with virt-manager and ssh-based libvirt url.

my main case was to scrape multiple messangers and apps with desktop ui only.

everything must run and render on server.
