-.IP "--vram-read, -vr [vmid@]<address> <size>"

 Read 'size' bytes (in hex) from the address specified (in hexadecimal) from VRAM
 to stdout.  Optionally specify the VMID (in decimal or in hex with a 0x prefix)
 treating the address as a virtual address instead.  Can use 'use_pci' to
 directly access VRAM.

 Write 'size' bytes (in hex) to the address specified (in hexadecimal) to VRAM
 from stdin.
