Hi,
Maybe a gluster encryption will also cover your needs in a hyper converged 
setup?

[ovirt-users] Re: multiple vm got stack after gluster server hardware failure

[g . vasilopoulos]

Thank you for your answer
most of the machines where marked with questionmark.
No I have not tried through virsh to shutdown the machines. 
Some machines marked with  "?" where active some where and I mean they where 
not responding to ping command neither could I shut them down through 
"poweroff" in the gui.
On the upside nothing is lost or destroyed.

[ovirt-users] Re: multiple vm got stack after gluster server hardware failure

[jeremy_tourville]

If you can define "stuck" with some more detail I am sure many here could help 
you further.  Are the VMs in question displayed as "paused" by the engine?  
Have you tried using virsh at the command line to see if you can shutdown or 
start the VMs?  I have found that sometimes virsh will work to interact with 
the VMs when the GUI interface will not.

[ovirt-users] Re: Ovirt Node 4.3.6 Logical Network Issue - Network Down

[jeremy_tourville]

I did some further testing.  In short, if I attach logical network/VLAN 103 to 
enp96s0f0 the network will come up and be available for use.  If I attach VLAN 
103 to enp96s0f1 the logical network never comes up.

I have sort of answered my own question, though I don't fully understand why.  

If my memory serves me correctly, I had used the exact same router setup on my 
4.2.7 Ovirt node.  I believe I was able to use VLAN 103 on either interface 
without issue.  Is there something different about 4.3.6 Ovirt node?  Is there 
some sort of rule that won't allow a logical network to be shared with the same 
interface as the interface for storage/gluster?

You can use encrypted file system managed from within the VM itself if the
OS support it (dm-crypt with LUKS on GNU Linux, BitLocker) which is the
most secure choice on this topic.
Encrypting the storage hosting the VM disks won't help once you access the
storage for booting the VM, at that point disks will be accessible without
encryption.

[ovirt-users] Re: oVirt Metrics Store Installation - Error during SSO authentication

[Shirly Radco]

Hi,

Where did you update the repos in the ovirt-metrics-installer" VM ?

Did you add the additional repos to /etc/yum.repos.d/ ?
You will also need to add the OpenShift repos to the second VM (master0 VM).

Best,

"I presume that inside oVirt the disk itself is marked as bootable, correct?"
yes.

"Which type has been assigned to it?" 
Type. What do you mean?

"In the original exported VM do you remember which type of disk/controller you 
used for the boot disk?"
VirtIO or VirtIO SCSI

"In case you can edit it (with VM powered down) and try both virtio and 
virtio-scsi as interface types."
Already done! No success...

The others linux machines are imported with success.

In the original exported VM do you remember which type of disk/controller

In case you can edit it (with VM powered down) and try both virtio and

[ovirt-users]Fwd: Re: Can ovirt-node support multiple network cards ？

[Roberto Nunin]

If I've understood clearly, your goal is to have two physical network
interfaces connected to one logical  network in ovirt-engine.
If this is the case, you can use bonding/teaming physical interfaces into
one and then connect that aggregation to the ovirt-engine logical network.

Moreover, as Jeremy stated, you can use that aggregated physical interfaces
to transfer VLANs, taking advantages on redundancy/resilience and
configuration flexibility.
