oVirt node and bonding options cutomizations
by Gianluca Cecchi
Hello,
when using CentOS as OS for hypervisor and mode=4 for bonding (802.3ad) in
the past I had to use lacp_rate=1 (aka fast), because I noticed problems
with the default lacp_rate=0 parameter.
Now I'm testing an oVirt node and I see that into the graphical interface
there are the options to set mode, link up and down delays, but not the
lacp_rate option.
It is a different environment from the one where I had to modify it, so I
will start with the default value and see if I get any problems again.
Now the ifcfg-bond0 file created at oVirt node level by the web mgmt
interface contains:
BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad"
Would I be able to modify it in case of need and have it persistent across
reboot, something like this:
BONDING_OPTS="miimon=100 updelay=0 downdelay=0 mode=802.3ad lacp_rate=1"
?
Thanks in advance,
Gianluca

epel and collectd
by Fabrice Bacchella
In the releases notes, even for the 4.6 rc, I see:
https://www.ovirt.org/release/4.1.6/
...
OpsTools currently includes collectd 5.7.0, and the write_http plugin is packaged separately.
But if I check the current state:
yum list collectd-write_http collectd
...
collectd.x86_64 5.7.2-1.el7 @centos-opstools-release
collectd-write_http.x86_64 5.7.2-1.el7 @centos-opstools-release
So I think the warning is not needed any more. One can uses both ovirt and epel without any special check.

mode 4 bonding for VMs with NetworkManager anyone?
by Gianluca Cecchi
Hello,
I'm testing ovirt node, both 4.1.5 and 4.1.6rc2.
I see that in both versions the network stack is configured with
NetworkManager enabled.
With plain CentOS I always disabled NetworkManager and only used classical
network service alone, so I have not background with NM, related to
hypervisor.
I have configured a vlan (untagged) for VMs, using bonding mode=4 (802.3ad).
I have some problems with my VMs: they are reachable from some parts and
not from others.
In parallel I have already asked network guys to crosscheck network
configurations of the datacenter, but I would like to have confirmation
that other ones are already using with success the combination of:
- NetworkManager on hypervisor
- bonding mode = 4 for VMs traffic
Another question for another aspect I never understood: with an environment
in the past (before 3.5 times if I remember well) I used 802.3ad but I had
to set lacp_rate=1 (fast) because I had connection problems with the
default lacp_rate=0 (slow) parameter.
I see that still the default is lacp_rate=0
Could it be the same this time? Is there any reason to set default
lacp_rate=0 in oVirt (or the reverse... ;-)?
Thanks in advance,
Gianluca

ovirt high points
by david caughey
Hi Folks,
I'm giving a demo of our new 3 node oVirt deployment next week and am
looking for some high points that I can give to the Managers that will be a
sell point.
If you could help with the below questions I would really appreciate it:
Who are the big users of oVirt??
Why oVirt and not vMware??
(we are a big vMware house so free doesn't cover it)
What is the future for oVirt??
Why do you use oVirt??
Any links or ideas appreciated,
BR/David

hyperconverged question
by Charles Kozler
Hello -
I have successfully created a hyperconverged hosted engine setup consisting
of 3 nodes - 2 for VM's and the third purely for storage. I manually
configured it all, did not use ovirt node or anything. Built the gluster
volumes myself
However, I noticed that when setting up the hosted engine and even when
adding a new storage domain with glusterfs type, it still asks for
hostname:/volumename
This leads me to believe that if that one node goes down (ex: node1:/data),
then ovirt engine wont be able to communicate with that volume because its
trying to reach it on node 1 and thus, go down
I know glusterfs fuse client can connect to all nodes to provide
failover/ha but how does the engine handle this?

Automatic snapshot
by Lionel Caignec
Hi,
I study the snapshot possibillities in ovirt.
I would like to make a cron running every day which:
- retrieve vm list from a specific cluster
- create a new snapshot (without memory) for every vm
- removes oldest snapshot to keep only 5.
I'm wondering what is the best approach to do that?
use a list of command in batch for "ovirt-shell", scripting a bit with python, using the api ovirt? Unless there is already something to find something.
Thank you for helping

More than one mgmt network possible?
by Gianluca Cecchi
Hello,
in site1 I have 2 oVirt hosts with ovirtmgmt configured on vlan167.
Now I want to add a server that is in site2 where this vlan doesn't arrive.
I have here a vlan 169 that does routing with the vlan 167 of site1.
Can I add the host into the same cluster or the only way is to "transport"
vlan167 into site2 too?
Thanks,
Gianluca

Your suggestion solved the problem.
In the UI relative flag still missing, but now VMs are using gfapi.
