Hello, I have followed this guide <https://github.com/01org/gvt-linux/wiki/GVTg_Setup_Guide> to configure and compile XenGT in my laptop. This laptop has an Nvidia Optimus configuration with a i7-4720HQ and a Nvidia 980m. I can boot Dom0 without any issues but when I try to create another domain with the parameters that are provided on the guide I get an error (rc=-3). This is the full trace from xl -vvvv create mio Parsing config from mio libxl: debug: libxl_create.c:1616:do_domain_create: Domain 0:ao 0x556b1df4f140: create: how=(nil) callback=(nil)
