I will open a PR to update the offending line of code to be more defensive
so it won't error.  We can't revert that change because it will
re-introduce a bug which causes the source nat IP to not be the primary IP
on the nic after a VR reboot.

I will open a PR to fix this right now so you can test it.

Thanks,

Hi Guys,

Thanks to Will Stevens we’ve managed to identify that the changes in cs_ip.py 
introduced in StrongSwan development were causing this blocker. I guess it 
managed to slip in, since it appears only on physical KVM hosts.

I’ve reverted back to the state of cs_ip.py before the changes and was able to 
start the VR with this commit:
https://github.com/swill/cloudstack/blob/8b4c36ef501a96742c52b4d532cc3adda25aa71b/systemvm/patches/debian/config/opt/cloud/bin/cs_ip.py

I guess we’ll need to create separate PR to address fixing this issue, and 
refactor the StrongSwan changes, so that it works with physical KVM hosts. I’ll 
be happy to assist with testing these changes.

Thanks,
Boris Stoyanov

Hello everyone,

We’ve hit this issue: https://issues.apache.org/jira/browse/CLOUDSTACK-9811

On our physical hosts environment we’re not able to start the VR, it appears 
that it’s looking for eth3 configuration but no such is available. We’ve 
narrowed down the issue only to 4.10, so it must been a change that went in 
there that is causing this.
Currently this issue is logged as Critical and I’m suggesting we escalate it to 
Blocker, as it is blocking the user to deploy a VM on a KVM physical host.

Does anyone recall any change that might have caused this?

Please find the logs attached and further details in the bug.

Thanks,
Boris Stoyanov
