Varun,

Not exactly documenting that “veth” is not saved on system reboot but this blog 
post may be useful for you:

Subject: Re: [Openstack] veth pair disappear after hardware reboot


Hello Mike,

Thanks a lot for replying.
No, I am not aware about veths not surviving a reboot. Is it mentioned in any 
document of OpenStack?

I have checked the Neutron services and they are absolutely fine after reboot. 
This problem is seen even when I kill/stop the network services and again try 
to start them.

Could you please tell me if there is any fix for this?

BR,
Varun

[Openstack] veth pair disappear after hardware reboot

2015-08-27 Thread varun bhatnagar
Hi,

I have OpenStack Juno installed on a multi-node step up. I have a cluster
running on that. In that cluster there are few VMs which are booting over
network from one of the VM. This works fine until I reboot my hardware.

As soon as the blades are rebooted I start my VMs, then, PXE boot doesn't
work. I did ovs-vsctl show before and after reboot and I can see a
difference in ports attached to the bridge (logs attached). The *veth*
pairs (qvoXXX) are getting disappeared after reboot.

Can anyone please suggest what could be done to avoid this?
