Kerla Files

Run the following command to try Kerla on QEMU:

qemu-system-x86_64 -m 512 -cpu Icelake-Server -serial mon:stdio \
    -netdev user,id=net0                                        \
    -device virtio-net,netdev=net0,disable-legacy=on            \
    -kernel kerla.x64.elf

Notable Changes

• The first cloud support for DigitalOcean: for example, my website is now powered by Kerla on DigitalOcean!
• boot2dump support: if an ext4 disk is attached over virtio-blk, kernel panic log will automatically saved into /kerla.dump.
