This is the QXL driver in libvirt/qemu. The VGA driver also reports 
VMware. Virtio-GPU reports Redhat.

I've tried updating the vga mem to 256MB but still see the same error.

When using Vertio-GPU the setting appears not to be applied (I'm using 
virsh to configure) as from the log it appears not to be passed into the 
QEMU system (I'm not sure how this driver works, perhaps it is limited 
to the host allocated vram).

For QXL though it does appear that 256MB is used (or at least the 256MB 
is visible in the QEMU log).
