Alioth
Alioth is an experimental KVM-based type-2 hypervisor (virtual machine monitor) in Rust implemented from scratch.
Important
Disclaimer: Alioth is not an officially supported Google product.
Quick start
-
Install Alioth from source,
cargo install alioth-cli --git https://github.com/google/alioth.git
-
Make an initramfs with u-root.
-
Boot a Linux kernel with 2 CPUs and 4 GiB memory,
alioth -l info --log-to-file \ run \ --kernel /path/to/vmlinuz \ --cmd-line "console=ttyS0" \ --initramfs /path/to/initramfs \ --mem-size 4G \ --num-cpu 2
Features
- Runs on
x86_64
andaarch64
. - Boots confidential VMs with AMD SEV, SEV-ES, or SEV-SNP, see coco.md for details.
- VirtIO devices
net
backed by a tap device,vsock
backed by host/dev/vhost-vsock
,blk
backed by a raw-formatted image,entropy
backed by host/dev/urandom
,fs
backed by virtiofsd with experimental Direct Access (DAX),- (WIP)
balloon
with free page reporting.
- PCI device passthrough based on VFIO/IOMMUFD.
- Other devices
TODOs
- device passthrough with legacy VFIO API (groups and containers),
- explore a better solution to ACPI DSDT to replace the pre-compiled AML bytes,
- increase test coverage,
- add missing documents,
- (long term) port Alioth to Apple's Hypervisor framework,
- performance, performance, and performance!
Acknowledgment
The virtualization implementation in Alioth takes the following projects as references,
The error handling practice is inspired by
GreptimeDB's
stack_trace_debug
.
