## Building and testing HermitCore on a real machine
0. In principle you have to follow the tutorial above. After the configuration (step 2) go to the subdirectory `linux`, which contains the source code of the Linux kernel. Configure the kernel with `make menuconfig` for your system. Be sure, that the option `CONFIG_HERMIT_CORE` in `Processor type and features` is enabled.
0. In principle you have to follow the tutorial above. After the configuration (step 2 in the above tutorial) go to the subdirectory `linux`, which contains the source code of the Linux kernel. Configure the kernel with `make menuconfig` for your system. Be sure, that the option `CONFIG_HERMIT_CORE` in `Processor type and features` is enabled.
1. Go back to the root directory of this repository and build with `make` the Linux kernel, the HermitCore kernel, the cross-compiler and the demo applications.
2. Install the Linux kernel and its initial ramdisk on your system (see descriptions of your Linux distribution).
3. Create the directory `hermit` in the root directory of your Linux system (`mkdir /hermit`).
4. Copy the HermitCore kernel and the demo applications to the new directory (`cp hermit/hermit.bin /hermit ; cp hermit/tools/iso/* /hermit`).
5. Boot your system.
6. Follow the above tutorial from point 5.
5. The IP device between HermitCore and Linux does currently not support IPv6. Consequently, disable IPv6 for the IP device `mmnif` with following command: `echo 1 > /proc/sys/net/ipv6/conf/eth0/disable_ipv6`.
6. Per default, the IP device uses a static IP address range. Linux has to use `162.168.28.1`, where HermitCore isles start with `192.168.28.2` (isle 0). The network manager must be configured accordingly and consequently the file `/etc/sysconfig/network-scripts/ifcfg-mmnif` must be created with following contents:
```
DEVICE=mmnif
BOOTPROTO=none
ONBOOT=yes
NETWORK=192.168.28.0
NETMASK=255.255.255.0
IPADDR=192.168.28.1
NM_CONTROLLED=yes
```
7. Boot your system.
8. Follow the above tutorial (*Building and testing HermitCore within a virtual machine*) from point 5.
