Hi Friends of oVirt
I'm trying to migrate my company from VMware to oVirt.
In my final tests, I set up 2 more VLANs in oVirt, (VM VLANs)
The Virtual Machines in these VLANs, can be reached from the external IPs
from the net range,
but from the Virtual machines only can ping the Host with the Bridge and
itself, can't reach the gateway. ¿?
I configured a IP Forwarding in the Host with the virtual machine, and
nothing changes...
Any idea ? This is the last duty before embrace oVirt in the company.
Look to the VLAN 100 configuration (My desired VM Network):

Vlans are layer 2, sounds like a tagging problem. Cisco switches? The tag
sticks to the host bridge, but is being stripped off when it leaves the
host.... Is your switch in access mode or trunk?

Hi Donny
We have HP Switches (HP 5406zl) and they are configurated on trunk mode.
(VMware is configurated to use that).
Any suggestion ?
Thanks for your response.

Are you configuring the vms interface with the vlan or tagging at the host.

I must admit that I don't understand your problem yet. When you ping
from inside your guest, where are your packets dropped?
I'd like to point that your "Hosting" network, as most VM networks, is
better off left without an IP address. The benefit of this is better
security (host TCP stack is not accessible from VMs) and less chances of
routing collisions from the host.
So unless you need to use the same network for something other than VM
communication, try to clear its address.
Regards,
Dan.

Hi,
To make it easier to understand what the situation is, it would help to
see your bridging configuration and your interface configration.
Something like:
#> ip addr
And

Hi Friends of oVirt
This the data required:
I have a HP Enclosure with a HP SAN.
I can't change the net settings in the switch because we have VMware
Virtual Machines in production in the same enclosure.
The switch is in Trunk Mode and all the traffic are in Tagged VLAN's with
ID's: 1,50,90,91 and 100.
I can play with 6 blades.
I in the first Blade I installed oVirt in hosted engine mode.
The only S.O is CentOS 7.1
I used inxi to brig the data for you:
My First Host is the only host until now (SPM) is the first data domain
(NFS) and contains the hosted engine machine.
I installed oVirt with ovirtmgmt in VLAN 1, over the interface eno1,
without any VLAN Tagged configuration.
This the data for my first host:
http://pastebin.com/dfC0XTQM
This the data for the Engine:
http://pastebin.com/JdrMSbj0
This the data for the Virtual Machine created in VLAN 50:
S.O : CentOS 7.1
SELinux: Permissive
IP ADDRESS: 192.168.50.8
PREFIX: 27
GATEWAY: 192.168.50.1
Interface: eth0
The Virtual Machine hasn´t any VLAN configuration.
In the 3 S.O, Network Manager is stopped and disabled, connectivity is
managed by the network daemon.
This is the data for the Networking in the admin interface:
http://postimg.org/image/lbypejxrh/

This the case
With No IP in the VLAN, and IP in the Virtual Machine, From the Virtual
Machine can ping myself (192.168.50.8) but I can't reach the gateway, can't
reach the host, can't reach Internet.
Any help is appreciated

I see the tap interface on the ovirtmgmt bridge which is in the
192.168.0.0/24 subnet but your vm has a 192.168.50.0/27 address. I
don't know why it's attached to that bridge though since it looks like
you've placed it on the dmz network. What happens if you change the IP
address in your test vm to something in 192.168.0.0/24 and then ping
your 192.168.0.1 gateway?

Hi Friends of oVirt
This the data required:
I have a HP Enclosure with a HP SAN.
I can't change the net settings in the switch because we have VMware
Virtual Machines in production in the same enclosure.
The switch is in Trunk Mode and all the traffic are in Tagged VLAN's with
ID's: 1,50,90,91 and 100.
I can play with 6 blades.
I in the first Blade I installed oVirt in hosted engine mode.
The only S.O is CentOS 7.1
I used inxi to brig the data for you:
My First Host is the only host until now (SPM) is the first data domain
(NFS) and contains the hosted engine machine.
I installed oVirt with ovirtmgmt in VLAN 1, over the interface eno1,
without any VLAN Tagged configuration.
This the data for my first host:
http://pastebin.com/dfC0XTQM
This the data for the Engine:
http://pastebin.com/JdrMSbj0
This the data for the Virtual Machine created in VLAN 50:
S.O : CentOS 7.1
SELinux: Permissive
IP ADDRESS: 192.168.50.8
PREFIX: 27
GATEWAY: 192.168.50.1
Interface: eth0
The Virtual Machine hasn´t any VLAN configuration.
In the 3 S.O, Network Manager is stopped and disabled, connectivity is
managed by the network daemon.
This is the data for the Networking in the admin interface:
http://postimg.org/image/lbypejxrh/
http://postimg.org/image/jtkyhqs8f/
http://postimg.org/image/7dwf1nb9f/

http://postimg.org/image/pv5ar5v3j/
http://postimg.org/image/dx8br0gq7/
http://postimg.org/image/baixp4b0j/
This the case
With No IP in the VLAN, and IP in the Virtual Machine, From the Virtual
Machine can ping myself (192.168.50.8) but I can't reach the gateway, can't
reach the host, can't reach Internet.
Any help is appreciated
Thanks Friends of oVirt

I found the reason of my Problem: the virtual machines can't write the ARP
table ¡¡¿?!!
When I manually use the command:
arp -s 192.168.XXX.XX 00:09:XX:XX:XX:XX
I can reach the gateway
I can't reach anything from my net segment but i can reach Internet (Double
¡¡¿?!!)
For the moment I wrote a script, but is awful to do this.
Any idea ?
Thanks in advance :)

Julian,
Lets try a more systematic approach (similar to what Donny suggests):
Please disable your arp script, and reproduce the situation where your vm
cannot connect to the outside.
It will be also a good idea to have the failing machine be the only powered
on machine connected to the network (bridge).
* from the machine os run a ping to a pingable destination outside of your
network (8.8.8.8?)
* run tcpdump on the hypervisor on several interfaces:
* the vm tap device (vnet0? vnet1?)
* the vm network bridge device (hosting?), where the tap device is
attached to. This should be visible via brctl.
* the vlan device underneath the bridge (this one should have a name like
'eno1.50' where eno1 is the physical nic and 50 is the vlan tag)
* the physical device (the ethernet nic)
The tcpdump command requires root privileges and looks like this: "sudo
tcpdump -n -i <device_name> icmp or arp"
What I assume we will see are only icmp requests (pings) and no icmp
replies (pongs). There might be also be only arp requests and
no arp replies.
What I am interested at is the arp broadcasts, as the vm should broadcast
an arp request (who-is <my_gateway_ip>).
My first guess is that is no response or there is one but the vm cannot
hear it. This is why I used the arp filter in the tcpdump command.
This should shed some light on where the problem is and in which layer.
find out where the traffic is not forwarded.
Also, when you locate the point of failure, try and wait for the traffic to
'suddenly work' as you said and then figure out what was changed.
We would love to see the dumps and coontinue to help.
Thanks,
Ido

Thank very much
I love oVirt 3.6, so far so good.
