Export Domain no show
by Rajat Patel
Hi Ovirt,
We are using Ovirt 4.1 selfhosted engine attach nfs storega as
data/iso/export, we have one image which we want to import
(manageiq-ovirt-fine-4.qc2). We did copy to our export location
(/export/3157c57b-8f6a-4709-862a-713bfa59899a) and chnage the owner ship to
(chown -R 36:36 manageiq-ovirt-fine-4.qc2)issues is we are not able to see
at ovirtUI-->>Strorage-->>export-->>VM Import nither at Template Import. At
the same time not able to see error at logs.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
# yum clean all
# yum update
- don't help.
how to fix it ?

Move disk between domains

When i try to move a specific disk between storage domains i get an error.

All the other disks i can move.
The issue here is how i got this storage domain into ovirt i think.
I set up a new cluster using 4.1 coming from 3.6.
I imported a domain from the 3.6 cluster. I am trying to move this disk to
one of the new storage domains on the 4.1 cluster.
Any help would be greatly appreciated

I changed the subject to better address and track the thread..
You are not convincing me...
The term "file size" is ambiguous in this context...
If I take a disk that was born on this oVirt environment itself I have this:
https://drive.google.com/file/d/1Dtb69EKa8adNYiwUDs2d-plSMZIM0Bzr/view?us...
that shows that is thin provisioned
Its id shown here:
https://drive.google.com/file/d/1PvLjJVQ3JR4_6v5Da7ATac5ReEObxH-A/view?us...
If I go and check on my exported file system I get this

Why not? You can detect the format of source and use a similar strategy of
the bugzilla I'm referring (see below)
Or couldn't you use something like
rsync -av --sparse source target
if the target is NFS?
> Maybe this file was crated with preallocation=full?
>
In virt-manager there is not this logic by default.
The default format is qcow2/sparse
When you create/add a disk you can choose "Select or create custom storage":
https://drive.google.com/file/d/1gAwjAG5aRFC5fFgkoZXT5wINvQnov88p/view?us...
And then choose a format between:
raw, qcow, qcow2, qed, vmdk, vpc, vdi
In my case it was the default one, so qcow2, as qemu-img correctly detects.

In this bugzilla, that is related to export from NFS to block:
https://bugzilla.redhat.com/show_bug.cgi?id=1358717
it seems to understand, from a comment of Maor, that
preallocate=2 --> sparse
what are instead the possible values of volFormat and their decodification?
In my case it detects
volFormat=4,
Could it be something similar to the bugzilla above? Can it change anything
if exporting with NFS 4.2 or using oVirt 4.2?
I think that if one has big qcow2 disk files that he/she desire to migrate
into oVirt, the process could be optimized
Thanks,
Gianluca

Re: [ovirt-users] 4-2rc hosted-engine don't boot error:cannot allocate kernel buffer
by Maton, Brett
Really short version ( I can't find the link to the ovirt doc at the moment)
Put hosted engine in to global maintenance and power off the vm
(hosted-engine command).
On one of your physical hosts, make a copy of he config and update the
memory
cp /var/run/ovirt-hosted-engine-ha/vm.conf .
vim vm.conf
Then start hosted engine with the new config
hosted-engine --vm-start --vm-conf=./vm.conf

4-2rc hosted-engine don't boot error:cannot allocate kernel buffer
by Roberto Nunin
Hi
after successfully deployed fresh 4.2_rc with ovirt node, I'm facing with a
blocking problem.
hosted-engine won't boot. Reaching the console via vnc hook, I can see that
it is at initial boot screen, but for any OS release available, I receive:
[image: Immagine incorporata 1]
then
[image: Immagine incorporata 2]
googling around, I'm not able to find suggestions. Any hints ?
Thanks

Best Practice Question: How many engines, one or more than one, for multiple physical locations
by Matt Simonsen
Hello all,
I read with Gluster using hyper-convergence that the engine must reside
on the same LAN as the nodes. I guess this makes sense by definition -
ie: using Gluster storage and replicating Gluster bricks across the web
sounds awful.
This got me wondering about best practices for the engine setup. We have
multiple physical locations (co-location data centers).
In my initial plan I had expected to have my oVirt engine hosted
separately from each physical location so that in the event of trouble
at a remote facility the engine would still be usable.
In this case, our prod sites would not have a "hyper-converged" setup if
we decide to run GlusterFS for storage at any particular physical site,
but I believe it would still be possible to use Gluster. In this case
oVirt would have a 3 node cluster, using GlusterFS storage, but not
hyper-converged since the engine would be in a separate facility.
Is there any downside in this setup to having the engine off-site?
Rather than having an off-site engine, should I consider one engine per
physical co-location space?
Thank you all for any feedback,
Matt

Scheduling daily Snapshot
by Jason Lelievre
Hello,
What is the best way to set up a daily live snapshot for all VM, and have
the possibility to recover, for example, a specific VM to a specific day?
I use a Hyperconverged Infrastructure with 3 nodes, gluster storage.
Thank you,
