Re: [CentOS] Xen hypervisor on CentOS 7.4 with modern UEFI server not booting from grub

Hi Chris, For completeness just wanted to mention that it is the first time I see in newer servers that it is not possible to PXE boot from the network using legacy mode (BIOS). It seems like the NICs are missing the required piece of code for that as all 4 NICs of that server fail to boot legacy

[CentOS] Xen hypervisor on CentOS 7.4 with modern UEFI server not booting from grub

Hi, I installed CentOS 7.4 on a modern Lenovo ThinkSystem SR630 server which uses UEFI. So far so good CentOS 7.4 works fine so then I went on to install the Xen hypervisor by following the instructions from the wiki (https://wiki.centos.org/HowTos/Xen/Xen4QuickStart). Unfortunately when I
