Ovirt 3:6 to 4:2 migration
by techieim
Hello Team Ovirt,
We are running Ovirt3.8 version in our prod, we want to upgrade to 3.8 to
4.2.
At present we have 2 (hyp A & hyp B)physical host ovirt 3.8 is running with
self hosted engine with data domain and iso one cluster and data center.
What we were thing do this migration in following fashion.
Plan A.
1. Attach export domain present infra.
2. Take backup all of running vm as export.
3. Detach export domain
4. Detach hyp B from cluster and data center
5. Install fresh ovirt 4.2 iso on hyp B
6. Install self hosted engine
7. Attach Data Domain
8. Attach Export Domain which was use in ovirt 3.8
9. Import all vm's from there to new ovirt 4.2
10. Once all the vm's got up and running poweroff hyp A
11. Install fresh ovirt 4.2 iso on hyp A and attach cluster.
Plan B.
1. Attach export domain present infra.
2. Take backup all of running vm as export.
3. Detach export domain
4. Detach hyp B from cluster and data center
5. Install fresh ovirt 4.2 iso on hyp B
6. Install self hosted engine
7. Attach Data Domain
8. Export from ovirt 3.8 to ovirt 4.2
9. Once all the vm's got up and running poweroff hyp A
10. Install fresh ovirt 4.2 iso on hyp A and attach cluster.
Thank a ton in advance we may be wrong with above step help us to win this
migration.

Cant create ISCSI data domain
by tehnic＠take3.ro
Hello all,
i try to create a new data domain on ISCSI storage following this documentation:
https://www.ovirt.org/documentation/admin-guide/chap-Storage/
Discovery of ISCSI target is working but after logging in to the target no LUNs are found or displayed, so i cant finish the procedure.
On the SPM i see an ISCSI session, and LUN 1 is attached as /dev/sdc.
The ISCSI system is a FreeNAS installation and im running ovirt 4.2.
Any suggestion how to solve this problem?

Ovf from vm.initialization.configuration.data
by Carlos Rodrigues
Hello,
I'm working on development of script to backup and restore ovirt VMs.
I saw some examples from sdk (https://github.com/oVirt/ovirt-engine-sdk
/tree/master/sdk/examples) to backup and restore VMs, but for backup
ovf VM i'm using the vm.initialization.configuration.data and this ovf
it keeps the snapshots information and don't have disks ids reference.
I would like to known if we have some method to get the ovf with disks
ids?
Regards,

Failed to Activated Host
by carl langlois
Hi
Today i had plan to start upgrading my installation to the latest 4.2. As i
was already on a 4.2.x version i have figured it will be easy .. well.guess
what i have having trouble re-activating one of the freshly upgraded host.
So here is the resume.
My setup have 3 hosts that are also part of a gluster pool. Those are the
original host that was use to setup the HA engine with glusterfs. One of
the 3 host is only used for arbiter and can also run the engine. But
nothing else can run on it because it is a fairly small machine.
I have also 6 others hosts for running vms that are not part of the gluster
pool.
So first thing i did to upgrade is set the global maintenance. Update the
Engine/restart the engine and remove global maintenance.. that went without
a glitch.
Next i choose the arbiter for the first machine to upgrade. Then set the
machine to maintenance run the upgrade and reboot the host. That went also
without a glicth.
Now here is the glitchy part. When i try to reactivate the host i got a
strange error with a gluster peer command that failed on a host that is not
in the gluster peer list.
Here is the two errors i had.
*"Gluster command [gluster peer probe ovhost3] failed on server
sfmo5002ov74."*
*"Add Host failed error: ovhost3 is either already part of another cluster
of having volumes configured return code: 3"*
One thing i do not understand is the sfmo5002ov74 is not part of the
gluster pool. It does not provide any bricks to the system.
Now i am not sure what to look for. I have stop the upgrade process until i
figure out the issue.
Any hints would be appreciated.
Thanks

More USB device redirection
by yunsur.shi＠gmail.com
We have more USB devices redir (There are 8)，But oVirt supports only 6.
How should I configure it.
/etc/engine-config/engine-config.properties
NumberOfUSBSlots.validValues=0..6
This 0..6 modify 0..8
engine-config -s NumberOfUSBSlots=8
engine-config -g NumberOfUSBSlots
NumberOfUSBSlots: 8 version: general
But No entry into force
Should I do？
Thanks

OVIRT 4.2: MountError on Posix Compliant FS
by jtorres＠bsc.es
Hi all,
I've deployed the ovirt Version 4.2.4.5-1.el7 on a small cluster and I'm trying to use as datastorage domain a configured Spectrum Scale (GPFS) distributed filesystem for test it.
I've completed the configuration of the storage, and the filesystem defined are correctly mounted on the client hosts as we can see:
gpfs_kvm gpfs 233T 288M 233T 1% /gpfs/kvm
gpfs_fast gpfs 8.8T 5.2G 8.8T 1% /gpfs/fast
The content output of the mount comand is:
gpfs_kvm on /gpfs/kvm type gpfs (rw,relatime)
gpfs_fast on /gpfs/fast type gpfs (rw,relatime)
I can write and read to the mounted filesystem correctly, but when I try to add the local mounted filesystem I encountered some errors related to the mounting process of the storage.
The parameters passed to add new storage domain are:
Data Center: Default (V4)
Name: gpfs_kvm
Description: VM data on GPFS
Domain Function: Data
Storage Type: Posix Compliant FS
Host to Use: kvm1c01
Path: /gpfs/kvm
VFS Type: gpfs
Mount Options: rw, relatime
The ovirt error that I obtained is:
Error while executing action Add Storage Connection: Problem while trying to mount target
On the /var/log/vdsm/vdsm.log I can see:
2018-07-05 09:07:43,400+0200 INFO (jsonrpc/0) [vdsm.api] START connectStorageServer(domType=6, spUUID=u'00000000-0000-0000-0000-000000000000', conList=[{u'mnt_options': u'rw,relatime', u'id': u'00000000-0000-0000-0000-000000000000', u'connection': u'/gpfs/kvm', u'iqn': u'', u'user': u'', u'tpgt': u'1', u'vfs_type': u'gpfs', u'password': '********', u'port': u''}], options=None) from=::ffff:10.2.1.254,43908, flow_id=498668a0-a240-469f-ac33-f8c7bdeb481f, task_id=857460ed-5f0e-4bc6-ba54-e8f2c72e9ac2 (api:46)

I know, that from previous versions on the GPFS implementation, they removed the device on /dev, due to incompatibilities with systemd. I don't know if this change affect the ovirt mounting process.
Can you help me to add this filesystem to the ovirt environment?
The parameters that I used previously are ok? Or i need to do some modification?
Its possible that the process fails because i dont have a device related to the gpfs filesystems on /dev?
Can we apply some kind of workaround to mount manually the filesystem to the ovirt environment? Ex. create the dir /rhev/data-center/mnt/_gpfs_kvm manually and then mount the /gpfs/kvm over this?
It's posible to modify the code to bypass some comprobations or something?
Reading the available documentation over Internet I find that ovirt was compatible with this fs (gpfs) implementation, because it's POSIX Compliant, this is a main reason for test it in our cluster.
It remains compatible on the actual versions? Or maybe there are changes that brokes this integration?
Many thanks for all in advance!
Kind regards!

Ovirt system crash when starting VM with Quadro GPU
by Wesley Stewart
I have recently been using an old Radeon R9 270X lying around without
issue, until this card seemed to have kicked the bucket.
I had an Nvidia Quadro P2000 lying around I thought I would try. After
installing it into my system, it showed up in the PCI device as
anticipated. I based both devices to my Windows 10 guest.
It shows up a a GP106GL and a separate audio component. The same thing
that happened with the AMD Radeon Card. The events just shows the VM's
being terminated without giving a reason, and I am hoping for some
guidance.
Currently using a single node setup, running ovirt 4.2.3. Any ideas or
places to check would be much appreciated!

Python-SDK4: Check snapshot deletion result?
by nicolas＠devels.es
Hi,
We're using ovirt-engine-sdk-python 4.1.6 on oVirt 4.1.9, currently
we're trying to delete some snapshots via a script like this:
sys_serv = conn.system_service()
vms_service = sys_serv.vms_service()
vm_service = vms_service.vm_service(vmid)
snaps_service = vm_service.snapshots_service()
snaps_service.service('SNAPSHOT-ID').remove()
This works, mostly... however, sometimes the deletion fails:
Failed to delete snapshot 'snapshot name' for VM 'vm'.
Is it currently possible to know via Python-SDK that the deletion
actually failed? I know I can check the state of a snapshot, but I'd
like to check the result of the task. Is that possible somehow?
Thanks.
