Re: [Xen-users] [Xen-devel] VGA passthough still not working

I propose to begin drafting a joint manual. Training system for forwarding to be divided into two stages: - Set the system up to the moment when the device can not be forwarding (xm pci-list-assignable-devices is empty) - Set up DomU vga_passthru = 1 after xm pci-list-assignable-devices gives a list of devices
# Xm pci-list-assignable-devices
