"virtio

virtio-vga / virtio-gpu is a paravirtual 3D graphics driver based on virgl. Currently a work in progress, supporting only very recent (>= 4.4) Linux guests with mesa (>=11.2) compiled with the option --with-gallium-drivers=virgl.

To enable 3D acceleration on the guest system select this vga with -vga virtio and enable the opengl context in the display device with -display sdl,gl=on or -display gtk,gl=on for the sdl and gtk display output respectively."

Just try to look at this section in Archlinux wiki.

NB: HOW DO I GET NEWLINES IN COMMENTS? \n, \r\n or <br> don't work.

@FredBezies: since packages were built successfully, I installed them manually from /tmp/yaourt... and it worked.

After reboot I tried virgl in a knoppix live-iso (native window, not via vnc or spice), but it doesn't seem to work:

knoppix@Microknoppix:~$ dmesg|grep drm

@linux2brain: or use an AUR wrapper which supports split packages.

See https://wiki.archlinux.org/index.php/AUR_helpers#Comparison_table

Just try a fully green line :)

@FredBezies: ...so manual install from sources directly ?

@linux2brain: just don't use any AUR wrapper which automatically install this split package like yaourt.

It will work better.

Hi, is it still not possible to just build qemu-git without qemu-headless-git being pulled in and install failing with the error message about conflicting each other? ::

Hi! Is it possible to only build qemu-headless-git and qemu-headless-arch-extra-git without having to install things like pulseaudio, sdl, vte, etc?

July 22nd, 2017 : changed PKGVER. Now it is release version.r-number of commits since last-release.git revision.

It is simpler to understand. For example, on july 22nd in 2017; we can see since 2.9.0 release, 2514 commits had been made.

You have to build then install packages. You can them install either qemu-git or qemu-headless-git this way.

Still getting error with the latest version. How do I install only one or the other?
