[pve-devel] [PATCH manager 1/1] ui: qemu: show hint about prerequisites for virgl display

[Stoiko Ivanov <s.ivanov@proxmox.com>]

since there is no hard dependency on the needed libraries (and we
cannot easily check if a fitting GPU is present in the GUI) - notify
the user about the prerequisites - else the error-messages might be a
bit confusing [0]
