Hi Steven, I downloaded the latest versions, neither solved it. Worked fine on the source (esxi7, win10) but on the target I got the garbled screens (fresh xcp-ng latest w xen orchestra home compiled. Inside xen orchestra as well as xcp center I get the garbled screens.
To do this I had to press E on the initial boot screen. Then I have to remove nomodeset AND vga=788. Also have to set xe vm-param-set uuid=bc63e326-25dd-1536-8c7e-703d554b83f5 platform:device_id=0001. Then press xtrl-x and it boots fine.
