Expand disk size of Rocky Linux 8 Vagrant box for libvirt provider

This short note shows you how to expand disk size and filesystem of Rocky Linux 8 Vagrant box for libvirt provider.

Vagrant Cloud by HashiCorp

Rocky Linux 8 official Vagrant box has 4GB of disk space. Sometimes we need more disk space to play with. When you use VirtualBox provider, there is a plug-in vagrant-disksize. For libvirt provider, there isn’t a plug-in.

Here is a Vagrantfile that expand disk size 4GB to 40GB.

• Line 18: libvirt.machine_virtual_size = 40 define disk size for VM.
• Line 22: growpart /dev/vda 1 expands partition size.
• Line 23: xfs_growfs /dev/vda1 expands filesystem.

Here is a log.
