Access framebuffer of guest VM

[mmueller2012]

Hi,

is there any easy way to access the framebuffer of a VM from user mode, for example to create a screenshot? While reading through the code I saw that it is possible to receive events when a plane gets active and that I might be able to find out the format of the plane by mmap-ing the guest mmio space, but how do I access the data of a plane?

Regards,
Michael
