Can´t use a VM Network VLAN, because the Virtual Machines inside can't reach the Gateway
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): http://postimg.org/image/7hrog0a2n/ http://postimg.org/image/68b40i1vr/ http://postimg.org/image/lu6mlshgp/ http://postimg.org/image/540o1qc0t/ http://postimg.org/image/4kyg787bt/ http://postimg.org/image/v7ralh7zb/ http://postimg.org/image/kn903cl03/ For any idea, thanks in advance
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. :) 2015-06-30 17:51 GMT-05:00 Donny Davis <donny@cloudspin.me>:

Are you configuring the vms interface with the vlan or tagging at the host. On Jun 30, 2015 7:28 PM, "Julián Tete" <danteconrad14@gmail.com> wrote:

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 #> brctl show Regards Soeren On 06/07/15 13:30, "users-bounces@ovirt.org on behalf of Dan Kenigsberg" <users-bounces@ovirt.org on behalf of danken@redhat.com> wrote:

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.

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:
This the data for the Engine:
This the data for the Virtual Machine created in VLAN 50:

Any help is appreciated

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
#> brctl show

Look to the VLAN 100 configuration (My desired VM Network):

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.

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:

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.

This the data for the Engine:
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:

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

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
#> brctl show
