|
|
|
|
```
|
|
apt install libguestfs-tools #needed for the virt-customize tool
|
|
|
|
wget https://cloud.debian.org/images/cloud/trixie/latest/debian-13-genericcloud-amd64.qcow2 #the current Trixie latest cloud image available
|
|
|
|
sha512sum debian-13-genericcloud-amd64.qcow2 #check against https://cloud.debian.org/images/cloud/trixie/latest/SHA512SUMS
|
|
|
|
|
|
#customize the image:
|
|
|
|
virt-customize -a debian-13-genericcloud-amd64.qcow2 --install qemu-guest-agent,curl,wget,nano,rsync,htop,tmux #tools I like to add
|
|
|
|
virt-customize -a debian-13-genericcloud-amd64.qcow2 --run-command "sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config" #to enable root login which is off by default
|
|
|
|
virt-customize -a debian-13-genericcloud-amd64.qcow2 --run-command "sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config" #to enable SSH authentication by password - my use choice
|
|
|
|
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:
|
|
Code:
|
|
|
|
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!
