[one-users] Migrate OpenNebula to another host

2015-02-14 Thread Hüning , Christian 
Hi everyone,

 

So I’ve set up OpenNebula with the SQLite DB and everything is fine. Now I
am tasked with changing the server which hosts OpenNebula and Sunstone,
since the other server is better secured and all in all in a more reliable
environment. Is there a guide for migrating ONE and Sunstone to another
server or would I basically just have to install it on the other server and
copy the database + configs ? What about the other opennebula-node nodes?

 

Some hints or help would be greatly appreciated ;-)

 

Cheers,

Christian

[one-users] netkvm driver not working in Windows 8 64bit

2014-12-03 Thread Hüning , Christian 
Hi everybody,

 

I have a problem to get the netkvm virtio driver up and running in a freshly
installed Windows 8 64bit installation. When I start up the VM it recognizes
and installs the networks card as a realteak card. When I then change the
driver to the latest virtio netkvm driver from Red Hat, Windows wants to
restart and then tells me it couldn’t initialize the network card. 

 

It’s weird because I used the drivers without problems in Windows Server
2012 VMs on the same installation. 

Does anybody know what the problem could be?

 

Cheers,

Christian

[one-users] ONE Virtual Router routing from inside to outside

2014-09-23 Thread Hüning , Christian 
Hi,

 

I have a Virtual Router Appliance working with a VLAN isolated (powered by
open vSwitch) network of VMs. I can route/forward from the outside network
to the inner VMs. Now I am facing the requirement to make a connection from
a VM inside the isolation network to a VM in the outside world. Is there an
easy or defined way to do that (e.g. easily activating NAT’ting in the VR
appliance)? Or would I rather have to build something on my own with
iptables etc?

 

Cheers,

Christian

Re: [one-users] Problem with Virtual Router 4.8

2014-09-10 Thread Hüning , Christian 
Hi folks,

 

I figured it out myself. It had to do with the automatically generated VLAN
ids from OpenvSwitch and the VMs not being on the same physical host. As it
seems my Cisco router would not allow these high(?) VLAN IDs. I tried
setting the VLAN Id to “5” manually and it worked! 

A quick view into Ciscos manual showed that in “normal VLAN” mode VLAN Ids
are only allowed to range between 1 and 1002. One can of course activate
“Extended VLAN “ mode and then you may provide VLAN IDs between 1006 and
4094. Is there a possibility to set a range for the automatically generated
vlan ids?

 

Cheers,

Christian

Betreff: [one-users] Problem with Virtual Router 4.8

 

Hi there,

i’ve got openVSwitch running in my environment and can effectively provide
vlan isolation. I now have 3 VMS which are in an isolated network
(10.10.0.0/24) and can ping each other. I’ve got a bunch of other VMs
outside (141.22.29.0/24) and now wanted to connected these two networks with
the Virtual Router Appliance. However after setting the appliance up
regarding to the documentation, the routing effectively won’t work. 

 

The behavior is as follows:

1.  I can access the VR via SSH

2.  The VR can reach the public network

3.  The VR can NOT ping the VMs in the private network

4.  I forward port 80 to a VM “inside” , this of course does not work.

 

Here’s my Context Set for the VR:

CONTEXT=[

DHCP="NO",

DNS="141.22.192.100 141.22.29.101",

FORWARDING="10.10.0.2:80",

NETWORK="YES",

NTP_SERVER="141.22.192.100",

PRIVNET="$NETWORK[TEMPLATE, NETWORK=\"MARS SimulationNetwork ISO\"]",

PUBNET="$NETWORK[TEMPLATE, NETWORK=\"MARSNetwork\"]",

RADVD="NO",

SEARCH="local.domain",

SSH_PUBLIC_KEY="$USER[SSH_PUBLIC_KEY]",

TARGET="hdb",

TEMPLATE="$TEMPLATE"

]

 

I am a bit lost here. NMAP however shows that port 80 is in “filtered” state
on the router.

 

Any suggestions?

 

Cheers,

christian

If everything else is working as you mentioned before, I would think that
you would only need to set those ports to trunk and allow all vlans to pass
through. After that, I would imagine you’d be able to separate VMs on the
same VLAN over multiple hosts, and ping between them.

 

That should be all you need to do at this point.

I have verified that all of these ports are set to “untagged”. So this is

Do I need to configure anything else on my hypervisor interfaces  or is it

Your colleague is probably correct. 

 

Have you verified that each of the ports on your physical switch, which the

4.8, OVS 2.0.1

 

Hi there,

 

I have a cluster of 5 hosts running with openNebula 4.8 and just recently
configured OpenvSwitch on all these nodes.

Networking is working just fine. This holds also true for VLAN isolation,
but just as long as the VMs belonging to the isolated Virtual Network reside
on the same physical host. When I move these VMs to different hosts, they
can’t communicate with each other anymore. Non-isolated nodes can
communicate to everywhere without problems.

 

Is that intentional? I chose OpenVswitch because the ONE docs say it
requires no support from the switch hardware (or more specifically it says
802.1Q would require support).

 

A colleague suggested it might have to do with the switch not forwarding the
tagged packets from Open vSwitch. Can that be the cause? Does OVS even tag
the packets?

 

Here’s my environment:

OpenNebula 4.8

Open vSwitch 2.0.1

Cisco Switch

Host OS: Ubuntu Server 14.04 LTS (latest patches)

 

Output from ‘ovs-vsctl show’:

  Bridge "br0"

Port "vnet3"

Port "bond0"

Interface "bond0"

Port "vnet1"

Interface "vnet1"

Where “br0” is my ovs bridge interface which has the external ‘real’ IP
address configured and “bond0” is a link aggregated dual Gbit interface
which is the port for “br0”

 

I would greatly appreciate some suggestions or ideas on this, since I am a
bit lost.

Cheers,

Christian
