That way, I could make the VM headless and still log in to see that the setup still worked. In my case, I made sure that the network device was working and that I could log in via SSH. If you want to test a particular facility using a standalone QEMU environment, make sure that this facility is also working. Make sure that your newly installed OS boots and that you can log in. Step 3: Boot and test the OS under virt-manager

Otherwise, I advise keeping things fairly minimal.

My only advice here is to make sure that you install whatever packages you need for testing purposes.

I also find it useful to note the network interface's MAC address so that I can assign it a suitable name on the system that provides DHCP services. Note: If you want to change your VM's chipset or firmware, do so before installing the OS. You might also want to change the Chipset setting to Q35 (from i440FX), assuming this value is not already the default. As an example, if you want your new VM to boot using UEFI, you can change the Firmware setting from BIOS to UEFI x86_64: /usr/share/edk2/ovmf/OVMF_CODE.fd. This action allows you to configure the chipset and firmware to your liking.

In step 5 of 5, on the Ready to begin the installation screen, check the box labeled Customize configuration before install.

If I want to install several VMs, I need to keep each one relatively small. As noted earlier, my virtualization host is also a VM, and I do not usually allocate more than 60GB of storage for that host.

In step 4 of 5, I leave the box labeled Enable storage for this virtual machine checked, but decrease the storage space to 10GB.

If you're going for a minimal install, or if your virtualization host doesn't have much memory (RAM), you might decrease the amount of memory from the default value.

In step 3 of 5, Choose memory and CPU settings, I usually choose the defaults.

I won't describe all the steps in detail because that has been done elsewhere.

Configure networking, architecture, and other hardware settings.

Configure the virtual machine's storage.

Locate and configure the installation media.

Name the guest VM and choose the installation type.

The New VM wizard breaks down installation to five steps: Step 1: Install a guest OS using virt-manager's New VM wizard (Follow the link for instructions for enabling nested virtualization on Fedora.) Running your virtualization host as a VM will make it easier to debug the virtualization host kernel if that is something you need to be able to do. If you want to do the same, you'll need to configure your virtualization environment to allow running nested VMs. The virtualization host that I used for my investigations was also a VM. Another option would be to use a clone of an existing VM. I advise against using a VM that you care about, so we'll start by using virt-manager to create a test VM from scratch. This article assumes that you created a VM with virt-manager or another tool in the libvirt framework. Note that I do not recommend the approach described here for a VM running in production (at least, not without backup). I hope this article makes it easier for you to configure and run your own QEMU-based VM for similar investigations. I found the process of configuring the test VM and writing the boot script more involved than expected, so I decided to document the steps I took. By default, libvirt runs with that option off, so I decided to set up a standalone QEMU environment. I was investigating an issue that required running QEMU with the machine option dump-guest-core=on. I recently needed to run a virtual machine (VM) created using virt-manager outside of libvirt.
