Development Environment (Vagrant)
|
|
=============================
|
|
|
|
Create Rocky Linux 9 virtual machine for Warewulf testbed using Vagrant
|
|
|
|
Host system requirements
|
|
=====================
|
|
|
|
#. CPU supports H/W virtualization.
|
|
#. KVM kernel module available and loaded.

CPU H/W Virtualization support
|
|
--------------------------------
|
|
|
|
Check CPU virtualization capability using following command. If your system has Intel CPU, you will see :code:`Intel VT` here, and if your system has AMD CPU, you will see :code:`AMD-V` here.
|
|
|
|
.. code-block:: bash
|
|
|
|
lscpu | grep Virtualization
|
|
Virtualization: AMD-V
|
|
Virtualization type: full
|
|
|
|
|
|
|
|
KVM kernel module
|
|
---------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
lsmod | grep kvm
|
|
ccp 118784 1 kvm_amd
|
|
kvm 1105920 1 kvm_amd
|
|
irqbypass 16384 1 kvm
|
|
|
|
|
|
Setup development environment on Rocky Linux 9
|
