NOTES
=====
This image introduces bootflow changes. We use now OpenSBI -> U-Boot (S-mode)
[extlinux] -> kernel. The kernel and initramfs are wrapped in U-Boot container
for now. This should change later this year once kernel header patches are
merged in kernel and U-Boot.
This image will work with libvirt v.5.3.0 (or above) and QEMU 4.0.0 (or above).
Tested also with libvirt v5.4.0 and v5.5.0.
This image allows updating kernels via dnf + reboot.
This image does not contain out-of-tree patches for SiFive Unleashed board.
This image is also available via virt-builder repository (not signed).
For example:
% virt-builder \
--source https://dl.fedoraproject.org/pub/alt/risc-v/repo/virt-builder-images/images/index \
--no-check-signature \
--arch riscv64 \
--size 20G \
--format qcow2 \
--hostname fedora1.builders.riscv.rocks \
fedora-rawhide-developer-20190703n0
See virt-builder man page for more information on how to customize disk images.
The disk image contains two partitions:
- sda1 (/boot) contains kernel, initramfs, extlinux configuration and firmware
blobs.
- sdta2 contains rootfs.
% virt-filesystems --long -h --all -a Fedora-Developer-Rawhide-20190703.n.0-sda.raw

To extract firmware blob install libguestfs-tools-c (Fedora/CentOS/RHEL), then:
% mkdir a
% guestmount -a $PWD/Fedora-Developer-Rawhide-*.raw -m /dev/sda1 $PWD/a
% cp a/opensbi/unstable/fw_payload-uboot-qemu-virt-smode.elf .
% guestunmount a
Use `fw_payload-uboot-qemu-virt-smode.elf` instead of the kernel.
libvirt (virt-instal):
[..]
--boot kernel=$PWD/fw_payload-uboot-qemu-virt-smode.elf \
[..]
QEMU:
[..]
-kernel $PWD/fw_payload-uboot-qemu-virt-smode.elf \
[..]
You do not need to specify bootargs, initramfs or actual kernel images. U-Boot
will read /boot/extlinux/extlinux.conf (from sda1) to load that information.
Record from extlinux.conf:
