First upgrade or reinstall your hosts with el7.
oVirt 3.6+ does not provide packages for el6. el6 hosts will
still work, but easiest to upgrade to el7 in 3.5.

If you are using hosted-engine, you can follow [1].

Then upgrade to 3.6 using regular docs [2].

In 4.0, the engine is also el7 only. To upgrade, use engine-backup
to backup, then reinstall the machine with el7, then restore. I do
not think we have a special page for this, but you can follow the
doc text of [3], which is also copied in the 4.0 release notes [4].
Please review [5] for more information about engine backup and restore.
If you using hosted-engine, you can use the new upgrade tool to upgrade
the engine vm using the engine appliance. Not sure that's properly
documented either, see also [6]. Also note that this bug is for 4.0.2,
to be released soon.

As always, if at all possible, better try first on a test system,
especially if it's in production, and backup everything beforehand,
including your VMs etc.

Hi,

I even attempted to run command virsh -c xen+ssh://root@xenhost and I

This is exactly the error message oVirt engine as well. You can see the

You are using "nics/setupnetworks", which is the old and deprecated
method. You should try to use "hosts/{host:id}/setupnetworks" instead.
For example, with curl:

---8<---
#!/bin/bash -ex

url="https://engine-fqdn/api;
user="admin@internal"
password="..."

curl \
--verbose \
--request POST \
--cacert /etc/pki/ovirt-engine/ca.pem \

Other than that you request looks correct and I think it should work.

NOTE: Consider using "/ovirt-engine/api" as "/api" won't work with
version 4 of the engine.

Re: [ovirt-users] Migrate machines in unknown state?

2016-08-09 Thread Nicolás 

Hi,

It worked (thanks Ekin, I'd probably had not turned it off and it would 
indeed been restarted), restarting libvirtd and vdsmd made all machines 
set their status to up. Seems the cuprit is libvirtd in this case, as I 
could see some errors in the log. I'm attaching the log FWIW.


Thanks.

Hi,

Just a reminder, if you have power management configured, first turn 
that off for the host - when you restart vdsmd with the power 
management configured, engine finds it not responding and tries to 
fence (e.g. reboot) the host.


Other than that, restarting vdsmd has been safe in my experience...

Hi,

We're running oVirt 4.0.1 and today I
found out that one of our hosts
has all its VMs in an unknown state. I
actually don't know how (and
when) did this happen, but I'd like to
restore service possibly without
turning off these machines. The host is
up, the VMs are up, 'qemu'
process exists, no errors, it's just the
VMs running on it that have a
'?' where status is defined.

Is it safe in this case to simply modify
database and set those VM's
status to 'up'? I remember having to do
this a time ago when we faced
storage issues, it didn't break anything
back then. If not, is there a
"safe" way to migrate those VMs to a
different host and restart the
host
that marked them as unknown?

Hi Nicolás,

I assume that the host these VMs are running
on is empty in the
webadmin,
right? if that is the case then you've
probably hit [1]. Changing their
status to up is not the way to go since these
VMs will not be monitored.

Hi Arik,

By "empty" you mean the webadmin reports the host
being running 0 VMs?
If so, that's not the case, actually the VM count
seems to be correct
in
relation to "qemu-*" processes (about 32 VMs), I
can even see the
machines in the "Virtual machines" tab of the
host, it's just they are
all marked with the '?' mark.

No, I meant the 'Host' column in the Virtual Machines
tab but if you
see
the VMs in the "Virtual machines" sub-tab of the host
then run_on_vds
points to the right host..

The host is up in the webadmin as well?
Can you share the engine log?

Yes, the host is up in the webadmin, there are no issues
with it, just
the VMs running on it have the '?' mark. I've made 3 tests:

1) Restart engine: did not help
2) Check firewall, seems to be ok.
2) PostgreSQL: UPDATE vm_dynamic SET status = 1 WHERE
status = 8; :
After a while, I see lots of entries like this:

  2016-08-04 09:23:10,910 WARN

I'm attaching the engine log, but I don't know when did
this happen for
the first time, though. If there's a manual way/command to
migrate VMs
to a different host I'd appreciate a hint about it.

Is it safe to restart vdsmd on this host?

The engine log looks fine - the VMs are reported as
not-responding for
some reason. I would restart libvirtd and vdsmd then


Is restarting those two daemons safe? I mean, will that stop all
qemu-* processes, so the

[ovirt-users] problem setting up bonding via rest in ovirt 3.6.6.2

2016-08-09 Thread Sven Kieske 
Hi,

I'd like to setup host network in the following way:

I have 4 interfaces: eth0, eno1, eno2, eno3

ovirtmgmt network resides on eth0 and is working.

Now I want to setup a bonding with the slave interfaces
eno2 and eno3 via the hosts "setupnetworks" function:

URL:

https://engine-fqdn/api/hosts/9cdcc85b-dd87-4dcf-9275-b993ee5b5e9c/nics/setupnetworks

Request:

"host_nic": [{
"name": "bond0",
"bonding": {
"options": {
"option": [{
"name": "mode",
"value": "1"

"value": "100"
}]
},
"slaves": {
"host_nic": [{
"name": "eno2"
}, {
"name": "eno3"
}]
}
}
}]
}
}

Response from ovirt-engine:

Action [hostNics] required for setupNetworks


When I look at the rsdl docs this seems perfectly fine.


I tried google with this error condition but it didn't return anything
useful unfortunately.

Your help would be greatly appreciated.

The official RH docs also do not mention anything else:

Is this sort of known problem or any reason to investigate?
It seems very strange to have reached this limit

I presume the agent runs as vdsm user and that the oVirt installation
creates the file
/etc/security/limits.d/99-vdsm.conf

with
# This limits are intended for medium VDSM hosts, for large hosts scale
these
# numbers appropriately.

# nproc should be the maximum amount of storage operations usage.
# VMs run by "qemu" user, vm processes are not relavent to "vdsm" user
limits.
vdsm - nproc 4096

# nofile should be at least 3(stdin,stdour,stderr) * each external process.
# 3 * 4096 = 12288
vdsm - nofile 12288

As a rough estimation (over estimation actually , due to many duplicates) I
have now:
# lsof -u vdsm | wc -l
488

Anything else to check?

You can set the disk format to COW. I will effectively be thin-provisioned.
I do this from the API, not sure if you can get the UI to do it.

Do you know if there is already an open ticket for that? if not,
opening one on https://bugzilla.redhat.com/ will help to get it fixed.

[ovirt-users] LVM2 Thinprovisioned

2016-08-09 Thread Fernando Frediani 

Hello all.

When you use oVirt with a Block Storage the only option available to 
store de VMs is LVM.


Does LVM in oVirt use Thinprovisoned (supported in LVM2) instead of 
having to use the SAN Thinprovisioned features ?

Actually, I solved my problem by solving a bug I was affected by (SELinux 
preventing to add storage domain), removing the unattached hosted_storage and 
restarting ovirt-engine.
It added it automatically with the VM as usual :)

Edit brick feature that can change a brick's network is not implemented -
it is dependent on the ability to call replace brick where source and
destination brick are the same. This is currently not possible in glusterfs
and hence https://gerrit.ovirt.org/51685 is not yet merged.

However, any brick that you create after you have associated gluster
network with an interface, say nic2, will use the interface nic2 for
creating bricks.

[ovirt-users] oVirt 4 and Gluster network

2016-08-09 Thread Arsène Gschwind 

Hi,

We have setup an oVirt 4 cluster using Gluster as storage backend.
I've setup a separate 10 Gb Network for Gluster traffic and tried to use 
that network as written in : 
https://www.ovirt.org/develop/release-management/features/network/select-network-for-gluster/


But I'm not able to find the "Edit - Brick" menu to be able to set the 
IP to use for existing bricks.

Is this not implemented yet? The feature status says "done".

I've been able to create new bricks using that network and it seems the 
traffic is going trough the right nics.


Thanks for any hint.
regards,

Arsène

It shows inactive, with a lock icon, but the engine is obviously online

Yes it is.

We've decided to rebuild the homelab due to poor infiniband support in
Fedora, so I won't waste anymore/anyone's time with these questions since
this installation is going to be wiped.

Yes, correct 

For RHEL6 / Centos 6 you can only have 3.5 vdsm and only in a 3.5 cluster

It’s highly recommended however that you upgrade your host to RHEL/CentOS 7
