Subject RE: Create GRE tunnel failed in 4.2 with XenServer.
Date Thu, 23 Jan 2014 12:18:40 GMT
Hi Murali, Tuna,

Thank you for this piece of information. All starts to make sense now.
I am wondering if there is a better way to communicate this issue to end users. It would save
others a couple of weeks struggling.
If GRE is not just a technology preview (meaning it has been explicitly mentioned in previous
release notes), the known issues lists for 4.2.0 and 4.2.1 should be explicitly updated.

Leaving 4.2 behind now, which will be the first release to include GRE refactoring with OVS
service provider ?

Regards,
Florin

Wow... I thought everything was done in XenServer before my submitted patch.
