Error attaching cd iso image from data domain
by Gianluca Cecchi 07 Jun '18

07 Jun '18

Hello, I'm with oVirt 4.2.3 (upgraded from 4.1 and compatibilities set to 4.2) I have a CentOS 7 VM. I correctly uploaded an iSO image to the disks of a data storage domain (iSCSI). Now in web admin portal I select the VM, then the 3 dots in top right, then change cd I'm proposed with the [Eject] line and into the dropdown I see the two iso images I have uploaded up to now. I select an image and then OK I get a window with title "Operation canceled" and content Error while executing action Change CD: Drive image file could not be found Do I have to edit any setting in my VM to be able to connect an ISO image this way? Or other things to check?

Ovirt node 4.2.1.1 patch/upgrade?
by Jakov Sosic 07 Jun '18

07 Jun '18

Hi guys, how do you upgrade ovirt nodes? I can't figure out the best practice from documentation. If I try `Check for upgrades` from oVirt Hosted engine interface, nothing happens. If I run `yum update` on an ovirt node, I get offered the following: ``` Installing: ovirt-node-ng-image-update noarch 4.2.3.1-1.el7 ovirt-4.2 643 M replacing ovirt-node-ng-image-update-placeholder.noarch 4.2.1.1-1.el7.centos ``` I can access all the CentOS packages if I run `yum update --enablerepos=base,updates,extras`. So, what is the proper way to do it? Thanks, Jakov

Asking about snapshot concept
by Terry hey 07 Jun '18

07 Jun '18

Dear all, I have a pre-allocated virtual machine. When i created a snapshot for that virtual machine, i found that it became thin-provision. And the size of the snapshot is same as the virtual machine. i would like to ask why these two behavior happened. 1. preallocated to thin provision 2. the size of snapshot is same as the disk size of virtual machine. Regards Terry

oVirt hosted-engine-setup issues with getting host facts
by Mariusz Kozakowski 07 Jun '18

07 Jun '18

Hello, We've been trying to setup oVirt environment for few days but we have issue with hosted-engine-setup (ansible script). We managed to fix few small things and have them merged upstream but unfortunately right now the installation process fails on getting host facts. It looks like it cannot proceed because it fails when connecting to ovirt-engine API of the bootstrap VM. The oVirt API / webpanel is working, I tested it via a browser and I can login without issues using the admin password chosen earlier in the process. 2018-05-18 15:26:47,800+0200 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:100 TASK [Wait for the host to be up] 2018-05-18 15:39:14,025+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 {u'_ansible_parsed': True, u'_ansible_no_log': False, u'changed': False, u'attempts': 120, u'invocation': {u'module_args': { u'pattern': u'name=host01.redacted', u'fetch_nested': False, u'nested_attributes': []}}, u'ansible_facts': {u'ovirt_hosts': []}} 2018-05-18 15:39:14,127+0200 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:98 fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": []}, "attempts": 120, "changed": false} May 18 13:34:34 host01 python: ansible-ovirt_hosts_facts Invoked with pattern=name=host01.redacted fetch_nested=False nested_attributes=[] auth={'timeout': 0, 'url': 'https://ovirt-dev.redacted/ovirt-engine/api', 'insecure': True, 'kerberos': False, 'compress': True, 'headers': None, 'token': 'R--token-redacted', 'ca_file': None} Do you have idea what/where is issue and how to fix it?

Debugging ceph access
by Bernhard Dick 06 Jun '18

06 Jun '18

Hi, as you might already know I try to use ceph with openstack in an oVirt test environment. I'm able to create and remove volumes. But if I try to run a VM which contains a ceph volume it is in the "Wait for launch" state for a very long time. Then it gets into "down" state again. The qemu log states 2018-05-25T15:03:41.100401Z qemu-kvm: -drive file=rbd:rbd/volume-3bec499e-d0d0-45ef-86ad-2c187cdb2811:id=cinder:auth_supported=cephx\;none:mon_host=[mon0]\:6789\;[mon1]\:6789,file.password-secret=scsi0-0-0-0-secret0,format=raw,if=none,id=drive-scsi0-0-0-0,serial=3bec499e-d0d0-45ef-86ad-2c187cdb2811,cache=none,werror=stop,rerror=stop,aio=threads: error connecting: Connection timed out 2018-05-25 15:03:41.109+0000: shutting down, reason=failed On the monitor hosts I see traffic with the ceph-mon-port, but not on other ports (the osds for example). In the ceph logs however I don't really see what happens. Do you have some tips how to debug this problem? Regards Bernhard

Is there something I am missing? thank you.

Backup VMs on oVirt 4.2+ with Disk image transfer
by wodel youchi 06 Jun '18

06 Jun '18

Hi, I am testing a product that can interface with oVirt API to backup VMs. The product can use v3 API (for oVirt 3.5.1+) with a proxy VM on oVirt to backup the VMs to the Export domain. And it can use v4 API (for oVirt 4+) to backup VMs, and it offers two methods for that : - for oVirt 4+ it can use Disk attachment mode, this mode uses a proxy VM on oVirt to attach the snapshot of the VM to be backed-up, and then the proxy VM can do the backup of the disk or communicate with an external backup software. This mode offers only full backups (pretty similar to v3). - for oVirt 4.2+ it can use Disk image transfer, this mode does not need a proxy VM, it exports data directly using the oVirt 4.2+ API to the backup server, and uses snapshot-chains provided by the new RHV/oVirt, which make it possible to have incremental VMs backups. I cannot get any documentation about the later approach (Disk image transfer), and my question is : what network does this approach uses to transfer the backup stream, is it ovirtmgmt network since we're talking to the API? My concern is about the bandwidth of this network, especially when backing-up huge and multiple VMs. Regards.

Hosted Engine Change State, VMs Images Locked?

So I have a few VMs that are locked and unable to start on either hypervisor, this happened after the hosted engine for some reason switched hosts.

Ovirt Node NG (4.2.3.1-0.20180530) Boot fail ISCSI using ibft after installation
by Ralf Schenk 05 Jun '18

05 Jun '18

Hello, I successfully installed Ovirt Node NG from ISO to an ISCSI target attached via first network interface by using following extensions to the grub cmdline: "rd.iscsi.ibft=1 ip=ibft ip=eno2:dhcp" I want to use the server as diskless ovirt-node-ng Server. After successful install the system reboots and starts up but it fails later in dracut even having detected correctly the disk and all the LV's. I think "iscsistart" is run multiple times even after already being logged in to the ISCSI-Target and that fails finally like that: *[ 147.644872] localhost dracut-initqueue[1075]: iscsistart: initiator reported error (15 - session exists)* [ 147.645588] localhost dracut-initqueue[1075]: iscsistart: Logging into iqn.2018-01.de.databay.office:storage01.epycdphv02-disk1 172.16.1.3:3260,1 [ 147.651027] localhost dracut-initqueue[1075]: Warning: 'iscsistart -b ' failed with return code 0 [ 147.807510] localhost systemd[1]: Starting Login iSCSI Target...

High latency events and events history settings
by Gianluca Cecchi 05 Jun '18

05 Jun '18

Hello, I'm going to debug some spot events I have in my iSCSI connection frm hypervisors. Sometimes I get May 31, 2018, 7:14:51 AM Storage domain ovsd3750 experienced a high latency of 8.96043 seconds from host ov200. This may cause performance and functional issues. Please consult your Storage Administrator. Jun 1, 2018, 5:26:25 AM Storage domain ovsd3750 experienced a high latency of 8.26526 seconds from host ov301. This may cause performance and functional issues. Please consult your Storage Administrator. Jun 2, 2018, 5:21:37 AM VDSM ov200 command SpmStatusVDS failed: (-202, 'Sanlock resource read failure', 'IO timeout') --> it seems no impact, actually, after a few seconds it becomes again SPM Jun 3, 2018, 7:00:14 AM Storage domain ovsd3750 experienced a high latency of 6.37818 seconds from host ov300. This may cause performance and functional issues. Please consult your Storage Administrator. And yesterday a VM running on ov301 node gets paused for a few seconds. Jun 4, 2018, 7:02:26 AM VM dbatest3 has been paused. Jun 4, 2018, 7:02:26 AM VM dbatest3 has been paused due to storage I/O problem. Jun 4, 2018, 7:02:40 AM VM dbatest3 has recovered from paused back to up. Some questions: - I'm investigating with the users, but in case it is indeed this VM causing problems on storage latency, what are my best chance to avoid it? To change disk profile for the disks of this particular VM? Or is there anything I can do globally? Or any settings on storage domain itself? What best practice? Is there a default sort of top I/O consuming barrier pre-defined on storage access speed from VMs? - How many days is the default history for events and how I can see it from web admin gui or other means? Can I change this dwfault and how? It seems I only see this possibly related parameter with engine-config command: EventProcessingPoolSize (with the value of 10 at this time) ? Any pointer to configure events' history retained settings? Thanks in advance, Gianluca

Microsoft Network Load Balancing
by Matthew Southwick 05 Jun '18

05 Jun '18

Any help appreciated. I have tried any and all combinations of network filters, custom network settings on vNIC, custom "macspoof" settings on the VM's. I have read countless blogs and examples. Could anyone please give me a simple list of items to check/change so that I can get windows network load balancing working between to VM's? At present, I have a network vNIC profile set to "No Network Filter" I have no custom properties on the virtual machines. I have no Network Filter Parameters set on the virtual machine vNIC.

Use case: small sites with a minimum number of vm's. Is there such a thing as a single host install? Is it valid for production use? What kind of storage?

How to increase the total space of storage domain
by Pym 05 Jun '18

05 Jun '18

Hi: In the management page of the web, the total space of the domain added to the storage domain page cannot specify a specific value. The total space value is determined by a specific code function based on the configuration parameters of the physical machine, or is it a fixed value？ Is there any way to modify this value? After I create multiple virtual machines, this space is not enough to continue to create virtual machines. How can I solve this problem? Thank you.

What are the steps to upgrade the 4.1 to 4.2?
by Arman Khalatyan 04 Jun '18

Hello everybody, I wondered if one could first upgrade the engine machine before upgrading the hosts. Is the engine 4.2.x is backwards compatible with 4.1.x? Thanks, Arman.
