[ovirt-users] Still running in to problems trying to implement OVN

[Mitchell Smith]

Hi List,

I was very happy to see overt added support for OVN recently, and it was a 
fairly strong factor in choosing overt for our current project, however being a 
very new feature with very little in the way of publicly available 
documentation, we are having some difficulties with implementation.

I have found a few very good articles on OVN itself and am comfortable with OVN 
cli for the most part, but translating that in to overt logical networks and 
NICs is proving to be quite a challenge.

As you might remember from one of my earlier posts, we do have some limitations 
with the current hosting provider also that make our network topology for this 
project less than ideal, but hopefully with OVN I can get to the desired 
outcome somehow.

So the first fairly big issue we run into relates to the  ovirtmgmt network, 
obviously this is a hard dependency of overt and it can’t be removed. As we 
only have one physical NIC in each server though, this causes some problems 
since we can’t also attach OVS to the same NIC as the ovirtmgmt bridge. Ideally 
we could set up OVN and just plug ovirtmgmt in to that network, but I can’t 
find any way to do that.

Secondly our public IPs each have a specific MAC attached to them, something in 
the 00:50:56 VMware prefix, I want to add these on OVN and then SNAT them to 
the VMs internal IP on the 10.x.x.x network, I can work out how to do this on 
the cli, but not in overt, should I just manually create these interfaces and 
then get overt to try and import them or similar?

As an alternative, am I making this type of network structure to complex by 
using OVN, and should I think about just creating a private address space using 
Tinc / PeerVPN / FreeLAN / similar, and then just set up a single VM with 
multiple interfaces on it acting as a router?

To try and explain the network structure a bit better, each server has one 
physical NIC with a public IP address, each server also has a /29, each 
individual IP has a MAC associated with it on the vendors firewall. I plan to 
have a private subnet across the whole cluster managed with OVN, which I will 
place VMs on. The public IPs will be transparently routed to the private IPs 
using OVN routers.

It’s less than ideal, but those are the constraints we have to work in for this 
project.

My final question is completely off topic for this mostly OVN themed email, but 
we have also been looking at ScaleIO from EMC, and it looks like a decent 
solution. We have built our proof of concept environment using Gluster but we 
are considering ScaleIO for the final implementation, and I was curious if 
anyone else had tried ScaleIO with overt, and did you find any advantages / 
disadvantages compared to Gluster?

I will end this rather long email here, but if anyone has tried to implement a 
similar network structure on overt, I would very much appreciate any 
suggestions you might have for the best way to proceed.

Thanks :)

Mitch

yes. 
That’s why we put a basic password protection to the plain virsh access. Easy 
to circumvent, but then you’re on your own…

Hm, how exactly were they powered on by virsh? Normally this is not possible 
for oVirt VMs at all due to initial set up of host-specific things(disk paths), 
we also use transient libvirt domains so stopped VMs are not defined in libvirt 
once they stop. So I wonder how exactly was this done?
Unless they were in Paused state where you indeed can simply continue the 
execution.

To answer your questions

We do not have power management configured due to it causing a cascading
failure early in our deployment.  The host was not fenced and "confirm host
rebooted" was never used.  The VMs were powered on via virsh (this
shouldn't have happened)

The way they were powered on is most likely why they were corrupted is our

We'd be happy if you could share both engine and host logs, including

that’s a mistake. The host should be fenced in that case, you likely do not
have a power management configured, do you? Even when you do not have a
fencing device available it should have been resolved manually by rebooting
it  manually(after fixing the disk problem), or in case of permanent damage

VMs in the meantime elsewhere) it should have been powered off and VM
states should be reset by “confirm host has been rebooted” manual action.

host is still Not Responding - was it not the case? How exactly you get to
the situation that you were able to power up the VMs?


However the disk image on a few of them were corrupted because once we
fixed the host with the full disk, it still thought it should be running
the VM.  Which promptly corrupted the disk, the error seems to be this in

This matches about with what we were thinking, thank you!

To answer your questions

We do not have power management configured due to it causing a cascading 
failure early in our deployment.  The host was not fenced and "confirm host 
rebooted" was never used.  The VMs were powered on via virsh (this shouldn't

[ovirt-users] VM running on multiple hosts

[Logan Kuhn]

We had an incident where a VM hosts' disk filled up, the VMs all went
unknown in the web console, but were fully functional if you were to login
or use the services of one.  We couldn't migrate them so we powered them
down on that host and powered them up and let ovirt choose the host for it,
same as always.  However the disk image on a few of them were corrupted
because once we fixed the host with the full disk, it still thought it
should be running the VM.  Which promptly corrupted the disk, the error
seems to be this in the logs:

No magic up to now: the host are simply in the DB you restored.
If the VM has network connectivity and the same host-name of the old
machine you shouldn't see any issue.
If you changed the host-name moving to the VM, you should simply run
engine-rename after the restore.

The only detail is that hosted-engine-setup will try to add the host where
you are running it to the engine and so you have to manually remove it just
after the restore in order to avoid a failure there.

Re: [ovirt-users] Odp: Re: How to upgrade self-hosted engine?

[Kasturi Narra]

Hi,

   upgrade HE (Hosted Engine ) by doing the steps below.

1) Move HE to global maintenance by running the command 'hosted-engine
--set-maintenance --mode=global'
2) Add the required repos which has higher package versions.
3) Run 'yum update ovirt\*setup\*'
4) engine-setup
5) Once the setup is done successfully please move HE out of global
maintenance mode by running the command 'hosted-engine --set-maintenance
--mode=none'

For upgrade node you can do the steps below:

1) If there is an upgrade link present in the 'General' tab of the UI, (if
ovirt node) click upgrade from UI which will move the host to maintenance
and run upgrade on the system, reboots and brings it back up to Normal
state.

2) If you do not see the upgrade link, then add the repos to which you
would want to update the node.

3) Run 'yum update'

4) Reboot the system.

5) make sure that you are on the latest image by running 'imgbase w' if it
is a ovirt node.

6)otherwise just make sure that you are on the latest kernel once your
upgrade finishes.

Hope this helps 

Thanks

Re: [ovirt-users] Odp: Re: How to upgrade self-hosted engine?

[gabriel_skupien]

To be honest, I dont see consistency regarding all that upgrade 
procedures. Have a look here:  www.ovirt.org www.ovirt.org  It asks to update 
the system too :)   I will appreciate if somebody clearly explains:  -to 
upgrade the Node - please do this and this  -to upgrade the Hosted-Engine - 
please do this and this.   G.

   If you follow that guide it will update everything on the 
virtual server
 running the engine. You should not run yum to upgrade the packages
 (correct me anyone if i am wrong about this)

 The engine-setup will download and install the packages for you.

 And on the nodes  upgrade first via the web interface and after that you
 can upgrade with yum on the nodes. Dont forget to have the node in
 maintence mode when you run yum update

[ovirt-users] trunk port for vm guest

[Charles Kozler]

Hello,

I have seen mixed results for this search on this list so I'd like to clear
it up

I have a VM that I need to configure with a trunk port so that all of my
VLANs can be configured on it but not as separate NICs (eth0, eth1, eth2,
etc)

I have seen on this list about a year ago someone said to setup a network
and leave it untagged and ovirt will pass all tagged and untagged packets
there. Then attach this to the guest VM and configure the trunk port inside
the VM (eth0:)

However, I saw also about 6 months ago someone suggest something like VLAN
tag 4095 so wondering if the support came in for this...or I should use
untagged VM network

So - how can I configure a trunk port for a guest VM?

Thanks

Is the host in non operational state now?
Could you please try moving it to maintenance mode to edit its network
configuration and then try activating it again?

So you managed to reach the conversion phase - that's a good progress.
We'll need the VDSM log that covers the time of the conversion on the host
that was selected as proxy in order to investigate the failure. Could you
please file a bug [1] and attach the log to that bug?

Objet: [ovirt-users] Failing to attaching master domain (nfs shares)

Hi,

i've just upgraded to 4.1 after some problem with PKI but now i'm facing 
problem with master data storage on one datacenter.

I've tried to reinitialize data center on new storage domain but same error 
(http://lists.ovirt.org/pipermail/users/2016-August/075569.html). 
I really does not understand because all my host see on 
/rhev/data-center/mnt/... all file of the storage domain.

What do i miss?

Please help ;)

[ovirt-users] LVM structure

[Nicolas Ecarnot]

Hello,

I'm still coping with my qemu image corruption, and I'm following some 
Redhat guidelines that explains the way to go :

- Start the VM
- Identify the host
- On this host, run the ps command to identify the disk image location :

# ps ax|grep qemu-kvm|grep vm_name

- Look for "-drive 
file=/rhev/data-center/0001-0001-0001-0001-033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75"

(YMMV)

- Resolve this symbolic link
# ls -la 
/rhev/data-center/0001-0001-0001-0001-033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75

- Shutdown the VM
- On the SPM, activate the logical volume :
# lvchange -ay 
/dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75


- Verify the state of the qemu image :
# qemu-img check 
/dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75


- If needed, attempt a repair :
# qemu-img check -r all /dev/...

- In any case, deactivate the LV :
# lvchange -an /dev/...


I followed this steps tens of times, and finding the LV and activating 
it was obvious and successful.
Since yesterday, I'm finding some VMs one which these steps are not 
working : I can identify the symbolic link, but the SPM neither the host 
are able to find the LV device, thus can not LV-activate it :


# lvchange -ay 
/dev/de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d
  Failed to find logical volume 
"de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d"


Either I need two more coffees, either I may be missing a step or 
something to check.
Looking at the SPM /dev/disk/* structure, it looks like very sound (I 
can see my three storage domains dm-name-* series of links).


As the VM can nicely be ran and stopped, does the host activates 
something more before being launched?

Re: [ovirt-users] Hosted-engine --deploy 4.1.6 - Web GUI Down

Why are you stopping firewalld? A better solution is to actually add 
firewall rules and open up what's needed.

Once everything is up/running deployed, peer-probed, ssh-keys are

gluster volume create engine replica 3 arbiter 1

Re: [ovirt-users] Hosted-engine --deploy 4.1.6 - Web GUI Down

[Kasturi Narra]

Hi,

 can you check what 'hosted-engine --vm-status' reports and can you
check if you are able to ping the hostname of HE vm from your hosts and the
machine where you are trying to access the browser ?

Thanks
kasturi

[ovirt-users] Impossible to add other host to hosted engine's cluster

[Demeter Tibor]

Hi, 
I've created a 3 host based hosted engine. I can't add other hosts to hosted 
engine's cluster. 

Before the setup, I have created a 3 node glusterfs for hosted engine on them. 
Because I would like use and separate vlans, I created two vlan bridge on all 
host. First is for ovirtmgmt, and a second for glusterfs. 
The hosted engine setup was successful but when I try to add other hosts, that 
is does not work, because vdsmd could not started. 
I found some network related errors in the logs: 

restore-net::ERROR::2017-09-19 19:14:48,072::__init__::51::root::(__exit__)

The four host network config is same, the ovirtmgmt bond.104 is the default 
route. 

How can I add another host to cluster?
