KVM Installed: Ensure you have KVM installed on your system. You can check if KVM is supported on your Linux system by running:
lsmod | grep kvm
If KVM is not installed, you can install it using your distribution's package manager. For example, on Ubuntu/Debian:
sudo apt-get update
sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
QCOW2 Image: You need a QCOW2 image. If you don't have one, you can create it by converting another image format to QCOW2 using qemu-img: pavmkvm801qcow2 new
qemu-img convert -f raw -O qcow2 /path/to/your/image.img /path/to/output.qcow2
Or create a new one directly:
qemu-img create -f qcow2 /path/to/new/image.qcow2 10G
| Issue | Command / Fix |
|-------|----------------|
| Corrupt image | qemu-img check -r all pavmkvm801qcow2 |
| Convert to raw for performance | qemu-img convert -f qcow2 -O raw pavmkvm801qcow2 pavm801.raw |
| Shrink unused space | virt-sparsify --in-place pavmkvm801qcow2 | Prerequisites
You could integrate pavmkvm801qcow2 new with:
Example cloud-init command with overlay: KVM Installed : Ensure you have KVM installed on your system
./pavmkvm801qcow2 new dev-vm --cloud-init user-data.yml
