Setting up Qemu with a tap interface

There are two parts to networking within QEMU:

• The virtual network device that is provided to the guest (e.g. a PCI network card).
• The network backend that interacts with the emulated NIC (e.g. puts packets onto the host's network).

Example: User mode network

Create an SSH key in PEM format

I have not been able to use ssh-keygen -e to reliably generate a private key for SSH in PEM format. This format is sometimes used by commercial products. Instead, I had to convert the key using openssl.

# generate an RSA key of size 2048 bits
ssh-keygen -t rsa -b 2048 -f jabba -C 'ronnie-jabba'

# copy key to 10.1.56.50 and add to authorized_keys

# 1) Download a prebuilt BusyBox binary here:
#    https://busybox.net/downloads/binaries/
#
# 2) Prepare your kernel
#    cp /boot/vmlinuz vmlinuz
#
# 3) Copy the files
#    install -Dm0755 busybox-x86_64 initramfs/bin/busybox

1. Take a backup of docker.service file.
   $ cp /lib/systemd/system/docker.service /lib/systemd/system/docker.service.orig

2. Modify /lib/systemd/system/docker.service to tell docker to use our own directory 
   instead of default /var/lib/docker. In this example, I am using /p/var/lib/docker
   
   Apply below patch.

   $ diff -uP -N /lib/systemd/system/docker.service.orig /lib/systemd/system/docker.service
