|
|
|
|
qemu-img convert -O qcow2 -c -o preallocation=off debian-13-genericcloud-amd64.qcow2 debian-13-genericcloud-amd64-shrink.qcow2 #convert & compress qcow2 image
|
|
```
|
|
|
|
#send image to PVE host:
|
|
```
|
|
scp debian-13-genericcloud-amd64-shrink.qcow2 root@........................... #enter desired location on host node
|
|
```
|
|
|
|
In PVE host:
|
|
|
|
* Create a VM 200 # use {vmid} you wish
|
|
* Name: Debian-Trixie-CloudINIT-Template #name I used
|
|
* Do not use any media, Qemu Agent (ticked), Remove all disk, 2 cores x86-64-v2-AES, 4096 RAM #settings I chose
|
|
* Set to not run on completion
|
|
|
|
|
|
In Host node shell:
|
|
```
|
|
qm importdisk 200 debian-13-genericcloud-amd64-shrink.qcow2 Storage --format qcow2 #change 200 to the actual {vmid} you used above & required Storage location, I used 'Storage'
|
|
```
|
|
|
|
|
|
In GUI of VM 200 (or your {vmid} as above):
|
|
|
|
* Remove the CD/DVD drive # I don't need one
|
|
* Add unused disk as scsi0, ssd on discard on default nocache #my choices, adjust accordingly
|
|
* Add cloud-init drive as ide0
|
|
* In cloud-init set User as root & password, set IPV4 as dhcp #my choices, adjust accordingly
|
|
* In VM Options set boot order scsi0 as first & only boot device
|
|
* Convert VM 200 (or your {vmid} as above) to Template
|
|
|
|
|
|
Done! #I make a backup of this VM template once done.
|
|
|
|
Testing:
|
|
|
|
* Create a Full clone
|
|
* Set Cloud-Init settings of the clone as required & regenerate Cloud-Init image
|
|
* Start cloned VM (This will fully setup the VM & should fully Update & Upgrade it)
|
|
* Shutdown
|
|
* In GUI; Remove Cloud-Init drive from Hardware
|
|
|
|
Done!
