Subject Noteworthy change to setting up XenServer :)
Date Mon, 03 Mar 2014 23:34:10 GMT
Hi everyone,

I spent the past day or so trying to figure out with various builds why I
could not add a XenServer host when creating a Basic Zone.

As it turns out, as Anthony noted in another e-mail today in response to my
issue, if you are using a security-group-enabled zone or a basic zone, you
need to switch XenServer's networking mode from OVS to bridge since
security groups don't work on OVS.

The moral of the story is that if you are running in such an environment,
run the following on your XenServer host before trying to add it:

xe-switch-network-backend bridge

It looks like a change went in in early February and since then you could
not successfully add a XenServer host to such a zone unless it was
configured as specified above.

By the way, does anyone know if this is documented?
