GRUB2 Netboot

GRUB netboot support is experimental.

Requirements

For local development, install the dependencies for libvirt with UEFI.

UEFI with QEMU

Application Container

Run the bootcfg ACI with rkt according to the development docs. Examples contains a grub.yaml config with a default machine group for GRUB net booting.

Client VM

Create a VM with an e1000 or virtio network device.

sudo virt-install --name uefi-test --pxe --boot=uefi,network --disk pool=default,size=4 --network=bridge=metal0,model=e1000 --memory=1024 --vcpus=1 --os-type=linux --noautoconsole

Network

On Fedora, add the metal0 interface to the trusted zone in your firewall configuration.

sudo firewall-cmd --add-interface=metal0 --zone=trusted

Add a grub.efi to tftpboot before building the dnsmasq ACI.

cd contrib/dnsmasq
./get-tftp-files
sudo ./build-aci

Build dnsmasq ACI with acbuild and run with rkt.

sudo rkt --insecure-options=image run dnsmasq.aci --net=metal0:IP=172.15.0.3 -- -d -q --dhcp-range=172.15.0.50,172.15.0.99 --enable-tftp --tftp-root=/var/lib/tftpboot --dhcp-match=set:efi-bc,option:client-arch,7 --dhcp-boot=tag:efi-bc,grub.efi --dhcp-userclass=set:grub,GRUB2 --dhcp-boot=tag:grub,"(http;bootcfg.foo:8080)/grub","172.15.0.2" --log-queries --log-dhcp --dhcp-userclass=set:ipxe,iPXE --dhcp-boot=tag:pxe,undionly.kpxe --dhcp-boot=tag:ipxe,http://bootcfg.foo:8080/boot.ipxe --address=/bootcfg.foo/172.15.0.2

Docker

The coreos/dnsmasq Docker image bundles a grub.efi.

sudo virt-install --name uefi-test --pxe --boot=uefi,network --disk pool=default,size=4 --network=bridge=docker0,model=e1000 --memory=1024 --vcpus=1 --os-type=linux --noautoconsole

sudo docker run --rm --cap-add=NET_ADMIN quay.io/coreos/dnsmasq -d -q --dhcp-range=172.17.0.43,172.17.0.99 --enable-tftp --tftp-root=/var/lib/tftpboot --dhcp-match=set:efi-bc,option:client-arch,7 --dhcp-boot=tag:efi-bc,grub.efi --dhcp-userclass=set:grub,GRUB2 --dhcp-boot=tag:grub,"(http;bootcfg.foo:8080)/grub","172.17.0.2" --log-queries --log-dhcp --dhcp-option=3,172.17.0.1 --dhcp-userclass=set:ipxe,iPXE --dhcp-boot=tag:pxe,undionly.kpxe --dhcp-boot=tag:ipxe,http://bootcfg.foo:8080/boot.ipxe --address=/bootcfg.foo/172.17.0.2
