Hi,
I have a fedora25 system with a Windows10 host and would like to use
it for photoshop. However, it complains the video memory is too low.
I'm using the QXL driver and it appears to be limited to 256MB? I've
installed the Red Hat QXL driver in Windows.
I have 4GB of memory allocated overall, and could allocate more if necessary.
How do I increase the available video memory? Photoshop reports that
it's detected less than 512MB and isn't operating properly.
When I view "Adapter Properties" is reports there is 2047 MB of
available graphics memory and
2047 MB Shared System Memory.
Attempts to modify with "virsh edit" the vram and other video-related
variables for the host have failed.
Included below is my qemu XML configuration. Any idea greatly appreciated.
