It's not limited and can be modified inside the xml, the only limitation is that the value has to be a power of 2 and for QXL the value must be at least 1024. There is an exception, qemu can and in some cases updates the value internally, libvirt after the guest is s...

Dear everyone Do you know how to modify vgamem value in the .xml file ? such as :<video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/> // from instance-0000015e.xml <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/</video> I

Hi Luo, the vgamem is limited inside. Myself, I use QEMU 2.5/Virgil3D to expand the vgamem. May be someone have a better solution or an example to solve it. Best regards, Holger ================================================================= example: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> . . <!--...

So you probably have some virtio-video-decoder. You allocate a gpu buffer, export it as dma-buf, import it into the...
