Re: [Openstack] veth pair disappear after hardware reboot
Varun, Not exactly documenting that “veth” is not saved on system reboot but this blog post may be useful for you: https://fosskb.wordpress.com/2014/06/10/managing-openstack-internaldataexternal-network-in-one-interface/ anthony.

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?

You know that veths do not survive reboot, right? It is up to Neutron or whatever needs them to create them after each boot.

[Openstack] veth pair disappear after hardware reboot
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?
