uhyve is small hypervisor to boot the library operating systems RustyHermit, which is a unikernel operating system targeting a scalable and predictable runtime behavior for HPC and cloud environments.
It is required to install the nightly version of the Rust toolchain on your Linux system. Please visit the Rust website and follow the installation instructions.
The final step is to create a copy of the repository and to build the kernel:
$ # Get our source code. $ git clone firstname.lastname@example.org:hermitcore/uhyve.git $ cd uhyve $ # Get a copy of the Rust source code so we can rebuild core $ # for a bare-metal target. $ cargo build
Use the hypervisor to start the unikernel.
$ ./uhyve /path_to_the_unikernel/hello_world
There are two environment variables to modify the virtual machine:
HERMIT_CPUS specifies the number of cores the virtual machine may use.
HERMIT_MEM defines the memory size of the virtual machine. The suffixes M and G can be used to specify a value in megabytes or gigabytes, respectively.
By default, the loader initializes a system with one core and 512 MiB RAM.
For instance, the following command starts the demo application in a virtual machine, which has 4 cores and 8GiB memory:
$ HERMIT_CPUS=4 HERMIT_MEM=8G uhyve /path_to_the_unikernel/hello_world
Setting the environment variable
1 makes the hypervisor print kernel log messages to the terminal.
$ HERMIT_VERBOSE=1 uhyve /path_to_the_unikernel/hello_world
