Hi Frank, Hi Remi,
great thank to both of you and really to Frank for do the work. Good Work!
I can test it on real setup. We will compile and test it. …
Really cool community work. Thanks

Hi Sven, Frank,
We hit this issue too last year in our CloudStack fork, and this is how we
resolved it:
https://github.com/MissionCriticalCloudOldRepos/cosmic-plugin-hypervisor-kvm/pull/14
Shouldn’t be too hard to port to current CloudStack, but I have no time to
do it and test it. We have been running like this ever since (18 months)
without issues.
Regards,
Remi

Betreff: Re: 4.9 / 4.10 KVM + openvswitch + vpc + static nat /
secondary ip on eth2?
Hi Frank,
Great analysis, but what can we do now? Is there a workaround or who
can fix this?

That seems to be a bug in the lookup of the device number, in case of
openvswitch.
The config clearly sets device to eth2, while it should be eth1.
More specifically:
in LibvirtComputingResource.prepareNetworkElementCommand()
The broadcastUriToNicNum map is filled depending on the VR nics.
In openvswitch the guest bridge is used as is, so it overwrites the
mapping of public.
This was not an issue until 4.6 as then VR was using the macaddress to
do lookup, while now it is using the device number.
Kind Regards,
Frank

I think that the bug you mentioned might not be related.
Could you please send the content of the file /etc/cloudstack/ips.json
on the VR.
That might provide useful information.
Kind regards,
Frank

Hi Devs,
i have the following problem.
When I look this jira ticket I see no solution.
https://issues.apache.org/jira/browse/CLOUDSTACK-6801 but I think the
problem is not solved correctly.
1. KVM
2. Bridges
bond with two interfaces and trunk (0,129,180,100-1500) to cloudbr0
Cloudbr0 (0 - guest network)
Fakebridge pub129 (public network)
Fakebridge sto180 (secondary storage network)
Fakebridge mgmt0 (management)
If I have a vpc all things work until I add a secondary ip and add a
static nat.
The following will happen, first address will be on the the correct
interface 146.0.122.134/26 but static nat will be on the false network.
Its on the eth2.
root@r-29-VM:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
link/ether 0e:00:a9:fe:03:81 brd ff:ff:ff:ff:ff:ff
inet 169.254.3.129/16 brd 169.254.255.255 scope global eth0
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
link/ether 1e:00:2c:00:00:68 brd ff:ff:ff:ff:ff:ff
inet 146.0.122.134/26 brd 146.0.122.191 scope global eth1
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP qlen 1000
link/ether 02:00:57:07:00:0c brd ff:ff:ff:ff:ff:ff
inet 192.168.1.254/24 brd 192.168.1.255 scope global eth2
inet 146.0.122.135/26 brd 146.0.122.191 scope global eth2
Normally I think the secondary ip should be on signed to eth1 not eth2!
It sets my ip on the guest network vlan range on my cloudbr0 but it
should be pub129. vnet6 has 1353 guest tag and not the public tag.
[root@kvm01 ~]# ovs-vsctl list-br

pub129

[root@kvm01 ~]# virsh domiflist r-29-VM

vnet6 bridge cloudbr0 virtio 02:00:57:07:00:0c

Port "vnet4"
Interface "vnet4"
Port "vnet5"
tag: 129
Interface "vnet5"

Whats wrong or what can I do to fix this? I hope anybody has an idea.
