Title:
NoCloud/network misordering network tasks
Status in cloud-init:
Expired
Bug description:
Hello, I'm using the NoCloud data source to spawn a ubuntu cloud image
locally with KVM. Unfortunattely the network configuration fails
because cloud-init pre-networking tasks try to find and match some
netdevs but fails because the netdevs aren't yet available in
udev/kernel. So Here is my configurations
# cat nocloud/meta-data
dsmode: local
instance-id: 2
local-hostname: vm1
public-keys:
- ssh-rsa AAAAB3NzaC1yc2EA....
# cat nocloud/user-data
#cloud-config
password: pass
chpasswd: { expire: False }
ssh_pwauth: True
cat nocloud/network-config
---
version: 2
ethernets:
ens2:
match:
macaddress: 52:54:00:10:00:02
set-name: ens2
dhcp4: false
addresses:
- 172.16.0.2/24
gateway4: 172.16.0.1
nameservers:
addresses: [1.1.1.1]
routes:
- to: 0.0.0.0/0
via: 172.16.0.1
Then I generate a seed iso file with:
# cloud-localds -N nocloud/network-config /var/lib/libvirt/qemu/images/${NAME}_seed.iso nocloud/user-data nocloud/meta-data
After then I boot my cloud IMG with the following cmd:
# virt-install -n vm1 \
-r 2048 \
--disk /var/lib/libvirt/qemu/images/vm1.img,format=qcow2,bus=virtio \
--disk path=/var/lib/libvirt/qemu/images/vm1_seed.iso,device=cdrom,format=raw \
--vcpus 2 \
--network network=mgmt,model=virtio,mac=52:54:00:10:00:02 \
--console pty,target_type=serial \
--graphics none \
--os-type Linux \
--virt-type kvm
The boot process starts and fails in at:

So clearly the pre-networking task is trying to match the configuration given in network-config file with the existing (not existing yet netdevs) configuration. Then cloud-init detects the net devices and displays them.
So I'm I missing something else in the configuration or it's just a resynchronization in the network configuration steps??
NB: I tested the 18.04 and 19.04 releases and It's the same behavior
since the version of cloud init is the same v19.4
Can you please tell me where is the issue?
Another thing, the user configuration when using dsmode: local is not set, I have the following error:
