Update EVE-NG

apt-get update -y
apt-get upgrade -y
reboot

Then you will probably have to power off/on the VM.

Check EVE Version

dpkg -l eve-ng
dpkg -l eve-ng-pro

Add More Storage

1. Just add a new HDD and EVE will auto-magically do the rest upon start up.
2. Then for a Linux machine:
   1. Only need to add a second hdd in image folder

virtiob.qcow2

1. To expand the Linux partition

   1. /opt/qemu/bin/qemu-img create -f qcow2 virtioa.qcow2 40G

Check Free Space
