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