I am using virtio-gpu on NVIDIA T4

when start VM by qemu cmdline:
##epoxy_internal_gl_version version=4.6.0 NVIDIA 510.47.03 ## version_string=7938
##epoxy_internal_gl_version version=4.5.0 NVIDIA 510.47.03 ## version_string=7938
gl_version 45 - core profile enabled

when start VM by libvirtd:
##epoxy_internal_gl_version version=2.1 Mesa 18.3.4 ## version_string=7938
##epoxy_internal_gl_version version=(null) ## version_string=7938
gl_version 0 - compat profile

who can tell me why ?
thank ...
