Re: Cloud init settings for Config Drive on L2 networks

2023-10-05 Thread Jorge Luiz Correa 
Just sharing some scripts used here. I hope they can help you.

Create file cloud.cfg_jammy

Change the following lines:
cloud_init_modules:
.
.
 - [ssh, always]

cloud_config_modules:
.
.
 - [set-passwords, always]

Download the cloud-set-guest-password-configdrive.sh script.

Create custom-networking_v2.cfg:

network:
  version: 2
  ethernets:
ens3:
  dhcp4: true

apt install libguestfs-tools
wget
https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img

virt-customize --run-command 'rm /etc/cloud/cloud.cfg' -a
jammy-server-cloudimg-amd64.img
virt-customize --upload cloud.cfg_jammy:/etc/cloud/cloud.cfg -a
jammy-server-cloudimg-amd64.img
virt-customize --mkdir /var/lib/cloud/scripts/per-boot -a
jammy-server-cloudimg-amd64.img
virt-customize --mkdir /var/lib/cloud/scripts/per-instance -a

virt-customize --upload
cloud-set-guest-password-configdrive.sh:/var/lib/cloud/scripts/per-instance/cloud-set-guest-password-configdrive.sh

virt-customize --upload
cnptia-per-instance-script.sh:/var/lib/cloud/scripts/per-instance/cnptia-per-instance-script.sh
-a jammy-server-cloudimg-amd64.img
virt-customize --upload
custom-networking_v2.cfg:/etc/cloud/cloud.cfg.d/custom-networking_v2.cfg -a
jammy-server-cloudimg-amd64.img

One important thing noted here, if you intend to use a DHCP server in this
L2 network, without static configured hosts. All VMs will be launched from
the same template and the /etc/machine-id will be the same. The DHCP client
will derivate one client id from this information. So, for all VMs, the
DHCP server thinks they are the same host, offerging the same IP. Caos!

I've read some documents and posts saying the image distributor (maybe
Canonical, distributing de qcow2 image), is the indicated figure to fix the
problem, making some configuration to reset the machine id. Indeed, if you
truncate (you cannot remove the file) /etc/machine-id and
/var/lib/dbus/machine-id, it will be generated on first boot.

Here, as the template is already uploaded and distributed to the Zone, I
made one ansible that fix this problem. But, I think you could run
virt-customize and truncate them.

Maybe:
virt-customize --run-command 'truncate -s0 /etc/machine-id
/var/lib/dbus/machine-id' -a jammy-server-cloudimg-amd64.img

Re: AW: KVM Host HA Settings

2023-10-05 Thread Nux 
If you only have local storage, then Host HA may make sense, at least if 
the hypervisor crashes have it rebooted via ipmi.

Test it and see if it behaves as expected.

Hello,

"By definition" you cannot have VM HA with local storage.

If your hypervisor goes down, through what process will the storage
of your VM be moved to another hypervisor and started there?

For VM HA you always must have network/shared storage, be it CEPH,
Storpool, Linbit etc - and always you need some NFS share for the
heartbeat - if the heartbeat NFS share were to become unavailable
all the hypervisors will fence themselves (forced reboot).

Subject: KVM Host HA Settings
Hi,

Bringing in new KVM hosts to CS 4.18.0.0.
How do you all configure Cloudstack to use "Host HA" for KVM hypervisor 
(preferably CS 4.18.0.0)?


Thanks so much!

Mit freundlichen Grüßen / With kind regards

You need to add a script in the template to get password from configdrive
and reset user password. For example
https://github.com/apache/cloudstack/blob/main/setup/bindir/cloud-set-guest-sshkey-password-userdata-configdrive.in

Cloud init settings for Config Drive on L2 networks

2023-10-05 Thread Joan g 
Hello Community,

Can someone guide me on configuration that should be added to cloud-init
settings for creating password enabled templates using configdrive in
ubuntu 20,22.

We need to deploy passsword and sshkey enabled templates on ubuntu that
will be using L2 networks.

Thanks joan
