Description Alon Bar-Lev 2013-03-28 08:09:16 UTC 
Hello,

We have a limitation of vdsm not able to create bridge on loopback.

This hopefully will be resolved next version in which bridge will not be created during host deploy.

For the meanwhile people experience failure when trying to deploy all-in-one, if their host name resolves to loopback device.

I suggest to check if fqdn of host is resolved to loopback during validation if all-in-one plugin is enabled and fail setup.

Thanks!

This bug and bug#948311 are related and can be solved using the same approach.

Verified on sf20 in 2 ways:

1. Change rhevm machine host name to 'localhost'.

2. Add rhevm machine host name to /etc/hosts, 127.0.0.1 line

Both gave the following error during engine-setup:

"Host fully qualified domain name. Note: this name should be fully resolvable  [localhost.localdomain] : 
The IP (127.0.0.1) which was resolved from the FQDN localhost.localdomain is not configured on any non loopback interface on this host"
