For below error: [ 5023.070461] vGT error:(g2h_gm_range:1660) VM(21): invalid address range: g_addr(0x1000), size(0x1000)
Likely you didn’t use a XenGT-aware i915 driver inside VM, which is required e.g. to handle address space ballooning. A simple way is to copy same Dom0 kernel/initrd/modules into guest image.
