Re: one question network survey

[Andrija Panic]

Hi Daan,

we have dedicated VLAN interface on all KVM hosts (bond0.XXX) which is used
as VTEP for our VxLANs - we are ACS advanced networking, 4.8, were used
also 4.5 previously).
MLAG configured from NIC1/NIC2 (bond0) to 2xTOR switches... pure (no OVS)
KVM/Ubuntu 14.04.

On the host side, we had to increase MTU for bond0.XXX since vxlan
interface gets 50bytes smaller MTU (..

If more help needed, please let me know.

Best,
Andrija

H Imran,
I am not sure I can get from your reply whether you configured anything for 
those vxlans inside cloudstack. It sounds like your just trunking upstream.
If I am wrong (not uncommon), you are probably talking about the guestnetwork 
as it ties your hosts together, right?

My question is mainly to what did you configure in cloudstack to use vxlans in 
your cloud.

Thanks,

Hope that answers your question if I have correctly understood your 
question.

Devs and users,

Can you all please tell me how you are using VxLan in your cloudstack 
environments?

The reason behind this is that I am planning some refactoring in the 
networkgurus and I don’t want to break any running installations on upgrade. If 
you are not using vxlan but know of people that might not react, using it, 
please point me to them.

Daan,


We use vxlan via the native driver on KVM. Our use currently is within standard 
isolated networks and VPC isolated networks. We use standard VLANs on the 
private gateways, but we're currently exploring some other methods there to 
eliminate our vlan requirement.

Hi Daan,

I use a separate trunk  (OVS or non OVS bonded with LACP ) connected to 
multiple switches (which are already configured into a switch stack). There can 
be multiple case scenarios but I am mentioning the most generic one .

Hope that answers your question if I have correctly understood your question.

Devs and users,

Can you all please tell me how you are using VxLan in your cloudstack 
environments?

The reason behind this is that I am planning some refactoring in the 
networkgurus and I don’t want to break any running installations on upgrade. If 
you are not using vxlan but know of people that might not react, using it, 
please point me to them.
