| Steps To Reproduce | minimal centos 7 install yum -y install centos-release-xen-410 yum -y update yum -y install xen yum -y install grub2-efi-modules cp -a /usr/lib/grub/x86_64-efi /boot/efi/EFI/centos/ edit /etc/grub.d/08_linux_xen change multiboot to multiboot2 change module to module2 grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg | ||||

I can confirm the same problem/solution on CentOS 7.8.2003 with Xen 4.12 with kernel 4.9.230 on a Dell R640 (which is a gen 14) BIOS 2.8.2. I followed the same steps, with a minimal install, and "yum -y install centos-release-xen-412" instead of the 4.10 repo. Side note: After 14 hours of this, I owe you a beer @colling2. |
