So I decided to let the user decide which "feature set" to use: * the default with up to OpenGL 4.3 support * OpenGL 4.6 (hostmem=G,blob=true) * Vulkan & OpenGL 4.6 (hostmem=G,blob=true,venus=true) https://www.qemu.org/docs/master/system/devices/virtio/virtio-gpu.html There is also a patch on the qemu-devel list which separates Vulkan from OpenGL. https://lists.gnu.org/archive/html/qemu-devel/2026-03/msg05502.html So in the future we could add a "vulkan without opengl" or "drm" option. The hostmem option allocates a host memory region that acts as virtual VRAM, enabling virglrenderer to map graphics 'blobs' directly to fixed memory addresses. https://www.mail-archive.com/qemu-devel@nongnu.org/msg1173963.html qeme-server: Markus Frank (1): fix #6277: virtio-vga-gl: add OpenGL 4.6 and Vulkan (Venus) support src/PVE/QemuServer.pm | 36 +++++++++++++++++++++++++++++++++++- 1 file changed, 35 insertions(+), 1 deletion(-) pve-manager: Markus Frank (1): ui: qemu: add VirGl feature selection in DisplayEdit www/manager6/qemu/DisplayEdit.js | 79 +++++++++++++++++++++++++++++++- 1 file changed, 77 insertions(+), 2 deletions(-) docs: Markus Frank (1): VirGL: add info about feature sets with OpenGL4.6 and vulkan qm.adoc | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) -- 2.47.3
