Re: [ovirt-users] how does ovirt deal with multiple networks with multiple gateways

[martin chamambo]

I am using ovirt 4.1.1.X.X  version on both nodes and Engine.
There are no static routes and the network topology is is such a way that
only the VMnetwork logical network is on a network with internet and has
got  a default gateway .

so i have
192.168.1.X  with a gateway of say 192.168.1.50 (This has internet) and
this is the VM network
 192.168.2.X , no gateway and is the ovirtmangnt
192.168.3.X  no gateway and its the display
,192.168.4.X , no gateway and its the Migration network
192.168.5.X , no gateway and its the Storage

when i set up these networks using the Ovirt engine GUI , ovirt seems to
create routes and rule files for each specific network ,but for some reason
, i cant ping anything besides the networks defined

[ovirt-users] how does ovirt deal with multiple networks with multiple gateways

[martin chamambo]

Hello

I am testing ovirt and i have configured it with 5 networks as shown below

Display , Migration , VMnetwork ,Storage and the default ovirtmngmnt
network

These networks are represented by individual phyiscal interfaces on the
ovirt nodes and for some reason the default gateway is not being set
correctly

it always seem to prefer the ovirtmngmnt interface as the default

The only network thats supposed to have internet is the VMnetwork role

Re: [ovirt-users] VDSM not properly setting the networking settings when

[martin chamambo]

Just noticed that VDSM creates these 2 files ,which should do  the routing

[root@node01 network-scripts]# cat rule-vmtraffic
# Generated by VDSM version 4.19.10.1-1.el7.centos
from 192.168.192.0/24 table 3232284815
from all to 192.168.192.0/24 dev vmtraffic table 3232284815
[root@node01 network-scripts]# cat route-vmtraffic

192.168.192.0/24 via 192.168.192.143 dev vmtraffic table 3232284815
[root@node01 network-scripts]#

But for some reason these are not working and i am not able to ping the
internet

[ovirt-users] VDSM not properly setting the networking settings when

[martin chamambo]

Here is my scenario

I have engine and 2 nodes  running on VMware workstation with 5 interfaces
each  with these responsibilities

vmtraffic - 192.168.192.X
display  - 192.168.193.X
storage - 192.168.194.X
migration- 192.168.195.X
ovirtmanagement - 192.168.196.X

Logical networks have been set up as above and all the networks are
reachablethe only network with a gateway is the vmtraffic

192.168.192.143 with gateway 192.168.192.2

when i go to the nodes via the terminal , it doesnt set the gateway and
theirfore that node when you do ip route ,i get this

[root@node01 ~]# ip route
192.168.192.0/24 dev vmtraffic  proto kernel  scope link  src
192.168.192.143
192.168.193.0/24 dev ens37  proto kernel  scope link  src 192.168.193.143
192.168.194.0/24 dev ens34  proto kernel  scope link  src 192.168.194.143
192.168.195.0/24 dev ens35  proto kernel  scope link  src 192.168.195.143
192.168.196.0/24 dev ens36  proto kernel  scope link  src 192.168.196.143
[root@node01 ~]#

I know the solution is to insert a static route but isnt the interface with
a gateway supposed to be default gateway for any traffic ?

and if i put the routes manually ,wont VDSM overwite it ,say if i upgrade.

Re: [ovirt-users] ISSUES WITH EDITING A CLUSTER SO IT CAN BE PART OF A NEW DATACENTER

[martin chamambo]

@gianlucca yes you are right that would have worked definitely...because a
prerequisite for removing a storage domain is having another say nfs or
iscsi as the master then decommissioning the old onei opted for the
longer route of deleting the data center, since I am also still testing the
platform.

I don't think there is a work flow we are missing...im still researching
for options and will update..but seems there is no easy way

Thats a far fetched solution koz a lot of iscsi connections are IP:3260 but
will definitely look into that regardless i ran into another issue when
i deleted the storage domains...so this will be for another time

[ovirt-users] ISSUES WITH EDITING A CLUSTER SO IT CAN BE PART OF A NEW DATACENTER

[martin chamambo]

I had issues with my master data storage domain and the only way was to set
the hosts in maintenence mode ,delete the datacenter so i can recreate
it

I managed to delete the datacenter and the storage domains , and created a
new datacenter , but now the existing clusters are not part of a datacenter
and trying to add them to the datacenter gives out this error below

Error while executing action: Cannot edit Cluster. Changing management
network in a non-empty cluster is not allowed.

and by non empty i guess it means there is a host inside that cluster ?
fair enough

trying to change a node cluster comes with the Host Cluster Dropdown with
this

Datacenter:Undefined

How can i fix the catch 22 scenario without deleting clusters or hosts..


surely there should be a smarter way ?

I configured openfiler as my iscsi storage and while i am able to connect
to it i wanted to change the IP address of the connecting IP to one of
the logical networks which i disignated as a STORAGE role.

This is a nightmare changing this and i have to set hosts in maintenence

is there any other way ?

[ovirt-users] for some reason ovirtnode creates unecessary vg and lvs

[martin chamambo]

I managed to configure the mail iscsi domain for my ovirt 4.1 engine and
node , it connects to the storage initially and initialises the data center
,but after rebooting the node and engine , it creates unecessary vg and lvs
like below

Re: [ovirt-users] How to re-initialize storage?

[martin chamambo]

I am not an expert but storage is tied to your datacenter so you need to
make sure your datacenter is removed so that you are able to remove storage

[ovirt-users] After adding ISCSI storage on ovirt 4.0 (both engine and node) , storage doesnt come up

[martin chamambo]

For some reason when i add iscsi storage on my ovirtNode it works like a
charm , but when i reboot the ovirtengine and node , the storage doesnt
come up and on the storage tab , i have noticed that the USE HOST dropdown
is empty

NB:iscsi and iscsid are running on the node and the LUN is active

Re: [ovirt-users] Installation of ovirtNode3.6 on VMware workstation is failing

[martin chamambo]

@Yaniv , OvirtNode 4.0 is working flawlessly , and the issue is with DISK
partitioning and VMware exposes the same drivers as with ovirtNode 4.0 
changing to thin LVM ddnt work either..

FYI - i am currently using ovirtNode 4.0 and OvirtEngine 4.0 and its working

Good day

I am using ovirtEngine 4.0 and ovirtnode 4.0  on the same engine i also
need to test ovirtNode 3.6 since its  supported.

Initially i struggled with installing ovirt engine 4.0 until i selected LVM

Planning on using ISCSI  , and it seems like defining logical networks is a
pre-requisite  for your host to come online and that error is happening
when i try to assign the ovirtmngmnt logical network to an interface
