Hi,
I have a fedora27 system with a win10 guest trying to use photoshop
2015. I've adjusted the vram parameter for the guest to 512M with QXL,
but photoshop still reports "3D features and some filters require
512MB vRAM and photoshop has detected less than that on your system."
What is the proper way to adjust the vram value to provide at least 512MB vram?
I've included my xml config below. I'm connecting to the guest using
VNC. I believe I have the server side configured properly for spice,
but do I need a windows client to use it to connect to the guest?

I guess this is the line that you need to change. Try changing vram to
something bigger (virsh edit $domain; virsh start $domain).
