+# importing a vm template into proxmox
+
+A standard KVM optimized Ubuntu 22.04 image can be imported via
+
+```
+TEMPLATE_URL=https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64-disk-kvm.img
+TEMPLATE_VMID=10000
+TEMPLATE_NAME=ubuntu-22.04
+TEMPLATE_STORAGE=tank
+TEMPLATE_DISK_OPTIONS="discard=on,iothread=1,ssd=1"
+
+curl -o template.img ${TEMPLATE_URL}
+
+qm create "${TEMPLATE_VMID}" --name ${TEMPLATE_NAME} --memory 16
+qm importdisk "${TEMPLATE_VMID}" template.img "${TEMPLATE_STORAGE}"
+qm set "${TEMPLATE_VMID}" \
+    --scsihw virtio-scsi-single \
+    --scsi0 ${TEMPLATE_STORAGE}:vm-${TEMPLATE_VMID}-disk-0,${TEMPLATE_DISK_OPTIONS} \
+    --boot order=scsi0 \
+    --cpu host \
+    --rng0 source=/dev/urandom \
+    --template 1 \
+    --agent 1 \
+    --onboot 1
+```
+Then for Ubuntu to work properly, you have to extend the `preK3sCommands` of both `KThreesConfigTemplate` and `KThreesControlPlane` with `apt update && apt -y install qemu-guest-agent && systemctl enable --now qemu-guest-agent`
