To set the amount of video memory to be available to the virtual machine’s video card, use the --videosize option of the prlctl set command. Assuming that the current video memory size of the virtual machine MyVM is set to 32 MB, you can increase it to 64 MB by running the following command:
# prlctl set MyVM --videosize 64
To check that the new value has been successfully set, use this command:
# prlctl list -i MyVM | grep video
video 64Mb
