Xhyve from Go
The goal of this project is to compile xhyve into a Go package and be able to distribute a Go binary with xhyve embedded.
Currently, the bindings are only for the
main() entrypoint in
the Go program to pass in any command line arguments to xhyve. This is a stop-gap for now,
and I welcome any effort to make actual Go bindings to the underlying xhyve functions.
I only tested on OS X Yosemite, which is the first OS X version to have Hypervisor.framework which is what xhyve leverages.
$ go get github.com/tiborvass/xhyve-bindings $ cd $GOPATH/src/github.com/tiborvass/xhyve-bindings $ go run main/main.go upstream/test/vmlinuz upstream/test/initrd.gz
Once in the VM, type
sudo halt to quit it.
- fork-exec: Go program should be able to run multiple xhyve instances. I suggest we use the reexec package.
- cross-compiling: We should be able to compile it from Linux. I was thinking of using xgo but any other solution that works should be good.
- management: Start, Stop and Kill fork-exec'd xhyve instance.
- pty: Not sure how important this is, but I wanted to have a way to attach and detach from the TTY.
Just send pull requests, open issues.
upstream/ directory is a git subtree. It's the first time I use that functionality
so bear with me. Suggestions welcome.
If you need to update upstream, run
make clean first, update upstream, and run
It will apply a small patch
upstream.patch that's currently needed.
By using cgo, we're limited to requiring all
*.c files at the root of the repository, hence
all those symlinks created by
generate.sh when doing
make. This also means, that no two
C files can have the same name.
