[ovirt-users] Re: Strange behavior when changing memory and virtual cpu for VM

2019-02-10 Thread Matthias Barmeier 
the VM is a plain debian9 VM. Other VMs with identical setup are still working 
as expected. Only when I try to change System settings I got this behavior..

Can you get a fresh Stretch VM working with networking that can ping out?

The VM contains debian 9 (stretch) with cloud init. Ovirt version: 4.2.7.5-1.el7

Hi Matthias,

it is really strange that update of the VM memory or CPU settings would 
trigger this cloud-init behavior inside the VM.


I would focus more on what's been happening with the VM after its 
creation and before the restart.

Few ideas and questions:
- Is it possible that the cloud-init has been installed or enabled later 
after the VM creation?
- Is the VM from pool? If yes, were there some changes made to the 
template, e.g., new sub-versions created, before the VM was restarted?

This means that the cloud-init service running on your VM is trying to 
reach the EC2 datasource[1]:

https://cloudinit.readthedocs.io/en/latest/topics/datasources/ec2.html

I am not familiar with cloud-init on Debian but there should be 120 
seconds default timeout to wait for the 169.254.169.254 address to 
return something,

it definitely should not wait forever.

This goes on for ever. What can I do to make the VM work again ? I tried to 
restore the settings to the values it has before but this does not help.

Hm. I'm not too familiar with cloud-init. Hopefully someone who knows that
better can chime in.
Did cloud-init get turned back on for this VM when you changed the
CPU/memory settings?

Can you get a fresh Stretch VM working with networking that can ping out?
