Hi,
I'm testing backup & restore on Ovirt 4.2.
I follow this doc https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/
Try to restore to a fresh installation but always get this error message:
restore-permissions
Preparing to restore:
- Unpacking file 'back_file'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
Restoring:
FATAL: Can't connect to database 'ovirt_engine_history'. Please see '/usr/bin/engine-backup --help'.
On the live engine I run # engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
And try to restore on a fresh installation:
# engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --restore-permissions
Any Idea?
Thanks

Unable to backend oVirt with Cinder
by Logan Kuhn
------=_Part_51316288_608143832.1472587678781
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 7bit
I've got Cinder configured and pointed at Ceph for it's back end storage. I can run ceph commands on the cinder machine and cinder is configured for noauth and I've also tried it with Keystone for auth. I can run various cinder commands and it'll return as expected.
When I configure it in oVirt it'll add the external provider fine, but when I go to create a disk it doesn't populate the volume type field, it's just empty. The corresponding command for cinder: cinder type-list and cinder type-show <name> returns fine and it is public.
Ovirt and Cinder are on the same host so it isn't a firewall issue.
Cinder config:
[DEFAULT]
rpc_backend = rabbit

Quack,
On behalf of the oVirt infra team, I'd like to announce the current
Mailing-Lists system is going to be upgraded to a brand new Mailman 3
installation on Monday during the slot 11:00-12:00 JST.
It should not take a full hour to migrate as we already made incremental
synchronization with the current system but better keep some margin. The
system will then take over delivery of the mails but might be a bit slow
at first as it needs to reindex all the archived mails (which might take
a few hours).
To manage your subscriptions and delivery settings you can do this
easily on the much nicer web interface (https://lists.ovirt.org). There
is a notion of account so you don't need to login separately for each ML.=
You can Sign In using Fedora, GitHub or Google or create a local account
if you prefer. Please keep in mind signing in with a different method
would create separate accounts (which cannot be merged at the moment).
But you can easily link your account to other authentication methods in
your settings (click on you name in the up-right corner -> Account ->
Account Connections).
As for the original mail archives, because the previous system did not
have stable URLs, we cannot create mappings to the new pages. We decided
to keep the old archives around on the same URL (/pipermail), so the
Internet links would still work fine.
Hope you'd be happy with the new system.

vdsClient is removed and replaced by vdsm-client
by Irit Goihman
Hi All,
vdsClient will be removed from master branch today.
It is using XMLRPC protocol which has been deprecated and replaced by
JSON-RPC.
A new client for vdsm was introduced in 4.1: vdsm-client.
This is a simple client that uses JSON-RPC protocol which was introduced in
ovirt 3.5.
The client is not aware of the available methods and parameters, and you
should consult
the schema [1] in order to construct the desired command.
Future version should parse the schema and provide online help.
If you're using vdsClient, we will be happy to assist you in migrating to
the new vdsm client.
*vdsm-client usage:*
vdsm-client [-h] [-a ADDRESS] [-p PORT] [--unsecure] [--timeout TIMEOUT]
[-f FILE] namespace method [name=value [name=value] ...]
Invoking simple methods:
# vdsm-client Host getVMList
['b3f6fa00-b315-4ad4-8108-f73da817b5c5']
For invoking methods with many or complex parameters, you can read
the parameters from a JSON format file:
# vdsm-client Lease info -f lease.json
where lease.json file content is:
{
"lease": {
"sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2",
"lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5"
}
}
It is also possible to read parameters from standard input, creating
complex parameters interactively:
# cat <<EOF | vdsm-client Lease info -f -
{
"lease": {
"sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2",
"lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5"
}
}
EOF
*Constructing a command from vdsm schema:*
Let's take VM.getStats as an example.
This is the entry in the schema:
VM.getStats:
added: '3.1'
description: Get statistics about a running virtual machine.
params:
- description: The UUID of the VM
name: vmID
type: *UUID
return:
description: An array containing a single VmStats record
type:
- *VmStats
namespace: VM
method name: getStats
params: vmID
The vdsm-client command is:
# vdsm-client VM getStats vmID=b3f6fa00-b315-4ad4-8108-f73da817b5c5
*Invoking getVdsCaps command:*
# vdsm-client Host getCapabilities
Please consult vdsm-client help and man page for further details and
options.

Passing VLAN trunk to VM
by Simon Vincent
Is it possible to pass multiple VLANs to a VM (pfSense) using a single
virtual NIC? All my existing oVirt networks are setup as a single tagged
VLAN. I know this didn't used to be supported but wondered if this has
changed. My other option is to pass each VLAN as a separate NIC to the VM
however if I needed to add a new VLAN I would have to add a new interface
and reboot the VM as hot-add of NICs is not supported by pfSense.

Can't add/remove usb device to VM
by Jon bae
Hello,
I run oVirt 4.2.1, in 4.1 I added a USB device to a VM and now I wanted to
change this device to a different VM.
But I found out, that I'm not able to remove this device nor I'm able to
add any device to any VM. The device list is empty.
I found a bug report, what describe this error:
https://bugzilla.redhat.com/show_bug.cgi?id=1531847
Is there a solution for that?
The USB device is a hardware dongle and it is very impotent for us to
change this.
Any workaround is welcome!
Regards

VDSM SSL validity
by Punaatua PAINT-KOUI
Hi,
I setup an hyperconverged solution with 3 nodes, hosted engine on glusterfs.
We run this setup in a PCI-DSS environment. According to PCI-DSS
requirements, we are required to reduce the validity of any certificate
under 39 months.
I saw in this link
https://www.ovirt.org/develop/release-management/features/infra/pki/ that i
can use the option VdsCertificateValidityInYears at engine-config.
I'm running ovirt engine 4.2.1 and i checked when i was on 4.2 how to edit
the option with engine-config --all and engine-config --list but the option
is not listed
Am i missing something ?
I thing i can regenerate a VDSM certificate with openssl and the CA conf in
/etc/pki/ovirt-engine on the hosted-engine but i would rather modifiy the
option for future host that I will add.

HostedEngine with HA
by Carlos Rodrigues
Hello,
I have one cluster with two hosts with power management correctly
configured and one virtual machine with HostedEngine over shared
storage with FiberChannel.
When i shutdown the network of host with HostedEngine VM, it should be
possible the HostedEngine VM migrate automatically to another host?
What is the expected behaviour on this HA scenario?
Regards,

Ceph Cinder QoS
by Matteo Dacrema
Hi All,
I’m running a 4.2 cluster with all VMs on Ceph using cinder external provider.
I’m trying to limit IOPS with cinder qos and volume type but it doesn’t work.
VM xml doesn’t show anything about <iotune>
Is it expected to work or is not implemented yet?
Thank you
