Hi Dag,
Thanks for your quick reply.
As you can easily understand, the goal of this lab job is to be moved to
production later on, so un-predictable options are not really options
(specially when you'll know that Shapeblue will probably handle the support for
us in the coming weeks:))
The goal is to move our current SAS 6gbits storage to 10 Gbe, so yes, I was
assuming management network to a new network card (10 Gbe), and storage as well
(to take advantage of 10 Gbe rather than staying on the 1 Gbe link).
When you say " Keep in mind the physical network is mainly cosmetic", does it
stand for :
"Physical Network 1
Management traffic (ex. : cs-mgmt label)"
Doesn't mean that cs-mgmt network should be related to eth0 on the physical
host ?
In other work, can I plug my new network card, rename cs-mgmt on the old one to
cs-mgmt-old and create cs-mgmt on the new one ?
If so, you are right, I will add the card and move the management label to the
10 Gbe.
But I assume I could do the same for the storage network label ?
Thanks again.
Best Regards.

Hi Gregoire,
First of all – I think you’re probably on very thin ice with this one – you may
be able to do this in the lab but it would be very risky to carry out in a
production environment.
Saying that – if you want to persevere and are happy this may break your lab -
a starting point would possibly be:
- Add the new cards to your XenServers.
- Create new networks in XenCentre – with new network labels.
- Not sure if this is required – but you would probably add the new physical
network using CloudMonkey. Keep in mind the physical network is mainly cosmetic
– your network configuration uses labelling only hence you may just use the
existing physical network.
- Stop CloudStack management.
- Hack the network labels in the cloud.host_details and
cloud.physical_network_traffic_types to reflect the new networks.
- On your XenServers / Xencentre move all existing networks (VLANs) to the new
networks (unsure of the steps or if this is possible).
- <insert other magic here>
- Restart management.
One other point – you mention this is for a *primary storage* migration – keep
in mind the storage network in the CS configuration is for *secondary storage*.
If all you want to do is to migrate to a new storage network and a new storage
backend your best bet is to:
- Add the new cards + configure the new storage network on the XenServers – no
need to label this.
- Present new primary storage pools from your NAS on the respective networks –
making sure the new NFS shares are only available over your 10Gbe network.
- Add the new NFS shares as new primary storage pools in the ACS gui.
- Storage migrate from old NFS shares to new.
This is a much simpler way and would be a supported configuration change.
Hope this helps,
Regards,

Dear All,
In my lab, I have a CS 4.7 advanced zone working fine.
I am now in the process of testing a primary storage migration (currently
SAS based to 10 Gbe nfs).
To perform this migration, I need to attach new network controlers (10 Gbe
controlers)
I have no problem for the hardware part of my work, but I am wondering how
CS can handle this change.
Right now, on my zone conf, I have :
- Physical Network 1
o Management traffic (with XenServer Label)
- Physical Network 2
o Public traffic
o Guest
o Storage
What is the best « CS way » to add my card (each with 2 10 Gbits ports),
add move management + Storage on the first port of the new card ?
- Physical Network 1
o No more traffic
- Physical Network 2
o Public
o Guest
- Physical Network 3 (first port of the new 10 Gbe card)
o Management
o Storage
I tried to play arround with create physical network, but I can't do much
with the newly created network (no way to assign traffic type to them).
Any help would be highly appreciated.
Best Regards.
