Have you ever thought you’re done with installing Ubuntu Server 22.04 using Libvirt’s virt-install, only to find yourself stuck on the console, wondering what went wrong? You’re not alone! This frustrating issue has plagued many a virtualization enthusiast, but fear not, dear reader, for we’re about to tackle this problem head-on and emerge victorious.
What’s Causing the Issue?
Before we dive into the solution, let’s take a step back and understand what’s causing this pesky problem. The virt-install command is supposed to create a virtual machine and install the operating system, but sometimes, it gets stuck on the console, displaying a blank screen or a flashing cursor. This can occur due to various reasons, including:
- Incompatible graphics settings
- Incorrect console settings
- Missing or incorrect kernel parameters
- Insufficient resources (CPU, RAM, or disk space)
- Buggy virt-install version
Preparing for the Solution
Before we proceed, make sure you have the following prerequisites in place:
- A working Libvirt installation (if you’re new to Libvirt, check out their official documentation for setup instructions)
- The latest virt-install version (update your package manager or use the
pip install virt-installcommand) - A functional Ubuntu Server 22.04 ISO file (download it from the official Ubuntu website)
The Solution: A Step-by-Step Guide
Now that we’re prepared, let’s tackle the issue step-by-step:
Step 1: Create a New Virtual Machine
virt-install --name ubuntu-server \ --ram 2048 --vcpus 2 --os-variant ubuntu22.04 \ --cdrom /path/to/ubuntu-server-22.04.iso \ --disk /path/to/disk,size=20,pool=default \ --graphics none --console pty,target_type=serial
Replace /path/to/ubuntu-server-22.04.iso with the actual path to your Ubuntu Server 22.04 ISO file and /path/to/disk with the desired location for your virtual machine’s disk.
Step 2: Edit the XML Definition
After creating the virtual machine, stop it using the following command:
virsh destroy ubuntu-server
Next, edit the XML definition using:
virsh edit ubuntu-server
This will open the XML file in your default editor. Look for the <graphics> section and replace it with:
<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'> <listen type='address' address='0.0.0.0'/> </graphics>
Save and exit the editor.
Step 3: Add the correct Console Settings
In the same XML file, add the following lines within the <devices> section:
<console type='pty' tty='/dev/pts/1'> <target type='serial' port='0'/> </console>
Save and exit the editor again.
Step 4: Define the correct Kernel Parameters
Within the <os> section, add the following lines:
<kernel>/usr/lib/xen-4.15/boot/hvmloader</kernel> <cmdline> console=ttyS0</cmdline>
Save and exit the editor once more.
Step 5: Start the Virtual Machine
Finally, start the virtual machine using:
virsh start ubuntu-server
Troubleshooting and Additional Tips
If you’re still experiencing issues, consider the following:
- Check the Libvirt logs for errors:
virsh --debug ubuntu-server - Verify your ISO file is not corrupted: try re-downloading the ISO or using a different one
- Ensure you have sufficient resources (CPU, RAM, and disk space) for the virtual machine
- Try using a different graphics setting, such as
--graphics vncor--graphics spice
Conclusion
By following these steps, you should have successfully installed Ubuntu Server 22.04 using Libvirt’s virt-install, avoiding the pesky stuck console issue. Remember to stay calm and patient, as virtualization can be complex and finicky. If you have any further questions or need additional assistance, don’t hesitate to reach out to the Libvirt community or seek help from online forums.
