This approach achieves a lower OS jitter and a better scalability.
HermitCore applications and the Linux system can communicate via an IP interface (e.g. inter-kernel communication).
HermitCore could be also used as classical standalone unikernel, which reduces the demand on resources and improves the boot time.
It is the result of a research project at RWTH Aachen University and is currently an experimental approach, i.e. not production ready. Please use it carefully.

## HermitCore as classical standalone unikernel
HermitCore applications could be directly started within a virtual machine.
HermitCore applications can be directly started within a virtual machine.
Currently, a file system is missing and a UART device is used as output device.
In the upcoming example, the console is redirected to the local host at port 4555.
To view the messages, *netcat* has to be started and to listen on port 4555.

Afterwards, a virtual machine has to be initialized, which used the HermitCore loader (`hermit/arch/x86/loader/ldhermit.elf`) to load HermitCore binaries as initrd.
No modifications to the binary are needed!
The described procedure does not require any modifications to the binary!
