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 Intel VT here, and if your system has AMD CPU, you will see AMD-V here.
lscpu | grep Virtualization
Virtualization: AMD-V
Virtualization type: full
KVM kernel module
lsmod | grep kvm
ccp 118784 1 kvm_amd
kvm 1105920 1 kvm_amd
irqbypass 16384 1 kvm
