grep -i disable /etc/xinetd.d/tftp disable = no 2.4) systemctl enable xinetd.service dhcpd.service 2.5) reboot the VM and check all desired services up and running systemctl status xinetd.service dhcpd.service tftp.service tftp.socket 2.6) link /tftproot to /var/lib/tftproot cd / ; ln -s /var/lib/tftproot 2.7) create a grub image for UEFI env execute this cmd on a uefi rhel7: grub2-mkstandalone -O x86_64-efi -o bootfile.efi --modules "tftp net efinet linux efifwsetup efi_gop efi_uga linuxefi lsefimmap lsefi lsefisystab" –net-directory /tftpboot 2.8) copy the bootfile.efi to the service VM(/tftproot) 3. boot a ovmf guest(virtio-net), from network(PXE) Actual results: VM hangs Expected results: VM should boot into grub env successfully Additional info: #
