How to Run Ubuntu Linux 24.04 on Proxmox

How to run Ubuntu Linux 24.04 LTS on Proxmox using the VirtIO drivers and QEMU agent for best practice.
The video is part of a Proxmox PVE Nested Virtualization home lab series, where we will be building out a lab environment to test Proxmox no subscription features and functionality.
Since Broadcom's acquisition of VMware, many customers are looking elsewhere for their virtualisation requirements - this video shows what you need to do for best practice when running Linux Ubuntu on Proxmox.
In this video, we set up Ubuntu 24.04 in Proxmox 8.2 using the VirtIO drivers and Qemu guest agent.
It demonstrates:
How to check if VirtIO the drivers are installed.
How to install the Qemu Agent.
How to test guest agent info is surfaced in the hypervisor
The command to check for VirtIO support is:
grep -i virtio /boot/config-$(uname -r)
If the value of CONFIG_VIRTIO_BLK and CONFIG_VIRTIO_NET is y in the response, it means that the kernel supports VirtIO by default, and no additional action should be necessary for this.
Ubuntu 24.04 supports VirtIO by default.
