I enabled the vga output by adding the option vga=current,keep in the Xen command line. The optional keep parameter causes Xen to continue using the vga console even after dom0 has been started. The default behaviour is to relinquish control to dom0. Xen still does not boot for me, but I'll ask that in a different thread. > On Thu 17 May, 2018, 6:35 PM Pratyush Yadav, wrote: >> >> Hi, >> >> I am trying to boot Xen on my Laptop.
