Network Interface order changed after reboot
by ovirt@timmi.org
Hi List,
I have two nodes (running CentOS 7) and the network interface order
changed for some interfaces after every reboot.
The configurations are done through the oVirt GUI. So the ifcfg-ethX
scripts are configured automatically by VDSM.
Is there any option to get this configured to be stable?
Best regards and thank you

InClusterUpgrade Scheduling Policy
by Scott
Hello list,
I'm trying to upgrade a self-hosted engine RHEV environment running 3.5/el6
to 3.6/el7. I'm following the process outlined in these two documents:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtuali...
https://access.redhat.com/solutions/2300331
The problem I'm having is I don't seem to be able to apply the
"InClusterUpgrade" policy (procedure 5.5, step 4). I get the following
error:
Can not start cluster upgrade mode, see below for details:
VM HostedEngine with id 5ca9cb38-82e5-4eea-8ff6-e2bc33598211 is configured
to be not migratable.
But the HostedEngine VM is not one I can edit due to being mid-upgrade.
And even if I could, the setting its complaining about can't be managed by
the engine (I tried in another RHEV instance).
Is this a bug? What am I missing to be able to move on? As it seems now,
the InClusterUpgrade scheduling policy is useless and can't actually be
used.
Thanks for any suggestions/help,
Scott

oVirt 3.6 to 4.0 Upgrade
by Brett I. Holcomb
In order to not hijack another thread I wanted to separate this from the
"latest CentOS libvirt updates safe?" thread since this is different
than what the OP on that thread wants to do.
I've been digging through the 4.0 documentation since I'd like to
upgrade in the not to distant future so I'm doing research and I'm confused.
I'm running 3.6.6 in a hosted Engine environment. My engine runs in a
vm on the host. The host is a physical box and the VMs are stored on a
NAS accessed by an iSCSI LUN, I have no other hosts running so I can
not migrate.
According to this link, https://www.ovirt.org/release/4.0.0/, I'm told
to simply run yum update ovirt-engine-setup and then engine-setup but I
assume that's for a non hosted-engine environment. I then go to the
link for Hosted_Engine_HOwto#Upgrade_Hosted_Engine guide and am told to
do this.
Set hosted-engine maintenance mode to global and other stuff that is
written assuming I have some place to migrate my VMs to. I do not have
another host.
So how do I properly move to oVirt 4.0 from 3.6.6 on a single physical
host running a hosted Engine VM?
Thanks.

Hi there,
I have hosted engine configured in my infrastructure and I just upgraded
from Ovirt 3.6 to Ovirt 4.0 yesterday.
Upgrade of hosted engine and my 2 nodes did ok. But now when I put one
node in maintenance, it prepares for maintenance ; unset SPM if it was
then migrate all the VMs to the another node. All of this steps are ok
but VM stays locked and in migration mode like this :
=2E Btw for the hosted engine I did migrate it manually.
So all the others VMs are stuck locked and in migration mode.
I did noticed every 10 minutes or so (pretty random), the
ovirt-hosted-engine HA is sending mail in this order :
1. EngineUnexpectedlyDown
2. (StartState-ReinitializeFSM sometimes)
3. EngineDown-EngineStart
4. EngineStart-EngineStarting
5. EngineStarting-EngineUnexpectedlyDown
6. Repeat
The hosted engine is pingable all this long, the web UI is reacheable
all this long too.
Anyone having this type of issues ? Do I open a bug on BugZilla ?
Thanks in advance,

oVirt/RHEV and HP Blades and HP iSCSI SAN
by Colin Coe
Hi all
We run four RHEV datacenters, two PROD, one DEV and one TEST/Training.
They are all working OK but I'd like a definitive answer on how I should
be configuring the networking side as I'm pretty sure we're getting
sub-optimal networking performance.
All datacenters are housed in HP C7000 Blade enclosures. The PROD
datacenters use HP 4730 iSCSI SAN clusters, each datacenter has a cluster
of two 4730s. These are configured RAID5 internally with NRAID1. The DEV
and TEST datacenters are using P4500 iSCSI SANs and each datacenter has a
cluster of three P4500s configured with RAID10 internally and NRAID5.
The HP C7000 each have two Flex10/10D interconnect modules configured in a
redundant ring so that we can upgrade the interconnects without dropping
network connectivity to the infrastructure. We use fat RHEL-H 7.2
hypervisors (HP BL460) and these are all configured with six network
interfaces:
- eno1 and eno2 are bond0 which is the rhevm interface
- eno3 and eno4 are bond1 and all the VM VLANs are trunked over this bond
using 802.1q
- eno5 and eno6 are bond2 and dedicated to iSCSI traffic
Is this the "correct" way to do this? If not, what should I be doing
instead?
Thanks

Error mounting hosted engine Volume (Glusterfs) via VDSM

Hello,
I think options for mounting the hosted-engine Volume changed in latest
vdsm to support mounting from backup-volfile-servers.

Source RPM : vdsm-4.17.28-1.el7.src.rpm
Now my hosts have problems to mount the Volume. On hosted-engine setup I
configured the (Replica 3) volume to be
"glusterfs.rxmgmt.databay.de:/engine" which ist a Round-Robin DNS to my
gluster hosts and _not_ the DNS-Name of any gluster-brick.
Now VDSM logs:

MountError: (32, ';Running scope as unit run-13461.scope.\nmount.nfs: an
incorrect mount option was specified\n')
So the mount is tried as NFS which hasn't the option "-o
backup-volfile-servers=3D...".
As a consequence the host is disabled in engine. The only way to get it
up is mounting the volume manually to
/rhev/data-center/mnt/glusterSD/glusterfs.
rxmgmt.databay.de:_engine and activate it manually in Management-GUI.
Should and can I change the hosted_storage entry-point globally to i.e.
"microcloud21.rxmgmt.databay.de" or wouldn't it be better globally that
VDSM uses "-t glusterfs" to try to mount the gluster-Volume regardless
which DNS Name for the gluster-service is used ?
Ovirt is:

<p>Hello,</p>
<p>I think options for mounting the hosted-engine Volume changed in
latest vdsm to support mounting from backup-volfile-servers.</p>
<p><tt>[root@microcloud28 ~]# rpm -qi vdsm</tt><tt><br>
</tt><tt>Name : vdsm</tt><tt><br>
</tt><tt>Version : 4.17.28</tt><tt><br>
</tt><tt>Release : 1.el7</tt><tt><br>
</tt><tt>Architecture: noarch</tt><tt><br>
</tt><tt>Install Date: Fri 10 Jun 2016 11:17:37 AM CEST</tt><tt><br>

</tt><tt>Source RPM : vdsm-4.17.28-1.el7.src.rpm</tt><tt><br>
</tt></p>
<p>Now my hosts have problems to mount the Volume. On hosted-engine
setup I configured the (Replica 3) volume to be
"glusterfs.rxmgmt.databay.de:/engine" which ist a Round-Robin DNS
to my gluster hosts and _not_ the DNS-Name of any gluster-brick.<br>
</p>
<p>Now VDSM logs:</p>

</tt></p>
<p>So the mount is tried as NFS which hasn't the option "-o
backup-volfile-servers=...".</p>
<p>As a consequence the host is disabled in engine. The only way to
get it up is mounting the volume manually to
/rhev/data-center/mnt/glusterSD/glusterfs.<br>
rxmgmt.databay.de:_engine and activate it manually in
Management-GUI.<br>
</p>
<p>Should and can I change the hosted_storage entry-point globally
to i.e. "microcloud21.rxmgmt.databay.de" or wouldn't it be better
globally that VDSM uses "-t glusterfs" to try to mount the
gluster-Volume regardless which DNS Name for the gluster-service
is used ?</p>
<p>Ovirt is:</p>
<p><tt>ovirt-release36.noarch 1:3.6.6-1</tt><br>

Setup new enviroment
by Andy Michielsen
Hello all,
I was just wondering what your opinions would be in setting up a new oVirt enviroment.
I have 4 old servers, 3 with 64 Gigs of ram and 2 tera's of disk space an one with 32 Gigs of ram and 1,2 Gb. Each has 2 hexcore cpu's. Each server has at least 2 nic's.
I would like to use each server in a seperate cluster with there own local storage as this would all only be used as a test enviroment but still would like to manage them from one interface. Deploy new vm's from templates etc.
Can I still use the all in one installation for engine and node ? Or can I install the engine on a seperate host, physical or virtual.
What would be a good way to use the network ?
Any advice would be greatly appriciated. Thanks in advance.
