Public bug reported:
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 B3NzaC1yc2EA
# 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:
