High level network advice request
by Richard Nilsson
High level network advice request :)
I have a self-hosted engine deployed on a node, Ovirt v. 4.3. I am testing, but I don't understand the big idea of how to set-up Ovirt networking for hosted / engine-managed virtual servers. I would like to host a few virtual servers for things like Next/OwnCloud, SuiteCRM, NethServer or others.
For example, I know exactly how set-up a virtual machine with a centos / lamp stack on a fedora host, I can make a network bridge for the vm with fedora cli, then use haproxy (or squid) as a reverse-redirect server to allow WAN access to the vm server using FQDNs.
What is a good strategy for Ovirt hosting a webserver? To use the default ovirt management network for the virtual server machines doesn't seem like a best practice?
Should I make a new logical network for the virtual servers? Do I need to configure bridges for the machines? It looks like bridges and virtual NICs are automatically configured when I make the network and virtual machines, is that right?
Is it the usual or typical practice that one ovirt logical network uses only one network bridge to a one physical NIC? Would all of the kVMs on the logical network share the same / single bridge of the particular network? I'm not sure what the big idea should be, what is a best practice?
I wonder, should I bond several physical NICs, then point the bridge, for a new / dedicated logical network for webservers, to the the bonded NICs? There is more than a little new vocabulary for me to onboard for Ovirt / virtual / logical networks...I will greatly appreciate, and I thank you in advance for any top level / best practice advice!

Assign permissions from within the VM portal?
by nicolas＠devels.es
Hi,
We're testing version 4.3.8, we're planning to upgrade to this version
in production as currently we're still using 4.1.9.
In 4.1.9, users could grant permissions on their created VMs to other
users from within the VM portal, however I can't find this option on
version 4.3.8.
Permissions granted to users so they can create and handle their VMs are
VmCreator and DiskProfileUser on the DataCenter.
Is there a way to allow users grant permissions on their VMs to other
users in the VM portal?
Thanks

problem with qemu / dynamic_ownership
by Christoph Köhler
Hey,
is the problem back with qemu/dynamic_ownership?
We have one DC with two clusters: one: vdsm-4.30.38 / libvirt-4.5.0-23,
two: vdsm-4.30.40 / libvirt-4.5.0-23, LibgfApi enabled, Gluster-Server
6.5.1, Gluster-Client 6.7, opVersion 60000
It went well for a log time but now, with getting vdsm like above, we
are getting old problems:
°setting disk files to root:root when VM went down
°cannot create snapshot etc.
Do we have to set dynamic_ownership=0 in qemu.conf? We were testing
anything but nothing other worked.
Is there any idea?

Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
by Strahil
I got upgraded to RC3 and now cannot power any VM .
Constantly getting I/O error, but checking at gluster level - I can dd from each disk or even create a new one.
Removing the HighAvailability doesn't help.
I guess I should restore the engine from the gluster snapshot and rollback via 'yum history undo last'.
Does anyone else have my issues ?

Async release for ovirt-engine-metrics is now available for oVirt 4.3.8
by Sandro Bonazzola
The oVirt Team has just released a new version of ovirt-engine-metrics
package that
fixes the deployment of the metrics solution when using foreman/satellite.
The deployment was previously failing on missing rhsub_orgid in
vars.yaml.template.
We recommend to update ovirt-engine-metrics if you're planning to use it
with foreman/satellite.
Thanks,

Virtual disk attached to VM showing in the Webui but not identified by the system
by Eugène Ngontang
Hi,
I'm facing a virtual disk behavior I don't understand.
Currently my VMs are spun up with a Boot disk of 25GB and an additional
disk of 215/45/65 GB depending.
When logged to the webui I see the two disks, but when I ssh to VM we only
see the primary boot disk, the other one can't get a *UUID* and then cannot
and is not mounted
I also noticed in the webui the second disk doesn't have a logical name as
you can see in the screenshot.
Pleas can someone explain this behavior please?
Here is my disk management commands outputs
