Unable to start VM
by Alex K 10 Jul '18

10 Jul '18

Hi all, I did a routine maintenance today (updating the hosts) to ovirt cluster (4.2) and I have one VM that was complaining about an invalid snapshot. After shutdown of VM the VM is not able to start again, giving the error: VM Gitlab is down with error. Exit message: Bad volume specification {'serial': 'b6af2856-a164-484a-afe5-9836bbdd14e8', 'index': 0, 'iface': 'virtio', 'apparentsize': '51838976', 'specParams': {}, 'cache': 'none', 'imageID': 'b6af2856-a164-484a-afe5-9836bbdd14e8', 'truesize': '52011008', 'type': 'disk', 'domainID': '142bbde6-ef9d-4a52-b9da-2de533c1f1bd', 'reqsize': '0', 'format': 'cow', 'poolID': '00000001-0001-0001-0001-000000000311', 'device': 'disk', 'path': '/rhev/data-center/00000001-0001-0001-0001-000000000311/142bbde6-ef9d-4a52-b9da-2de533c1f1bd/images/b6af2856-a164-484a-afe5-9836bbdd14e8/f3125f62-c909-472f-919c-844e0b8c156d', 'propagateErrors': 'off', 'name': 'vda', 'bootOrder': '1', 'volumeID': 'f3125f62-c909-472f-919c-844e0b8c156d', 'diskType': 'file', 'alias': 'ua-b6af2856-a164-484a-afe5-9836bbdd14e8', 'discard': False}. I see also the following error: VDSM command CopyImageVDS failed: Image is not a legal chain: (u'b6af2856-a164-484a-afe5-9836bbdd14e8',) Seems as a corrupt VM disk? The VM had 3 snapshots. I was able to delete one from GUI then am not able to delete the other two as the task fails. Generally I am not allowed to clone, export or do sth to the VM. Have you encountered sth similar. Any advice? Thanx, Alex

User permission. All user can access (start, shutdown) all vm in User/VM portal
by florentl 10 Jul '18

10 Jul '18

Hello, There is something I don't understand in permissions. I'm using Ovirt 4.2.3.5-1. I created a user : - ovirt-aaa-jdbc-tool user add etudiant2 --attribute=firstName=Etudiant2 --attribute=lastName=Etudiant2-Lastname - ovirt-aaa-jdbc-tool user password-reset etudiant2 --password-valid-to="2025-01-01 10:30:00Z" On the Administration Portal I gave him (etudiant2) the permission UserVmManager on only one VM and nothing else. But when he logs in the VM Portal he can view, start, stop all the VM. I think it's because all users are member of the group Everyone and this group has by default the UserRole. And in my config (the default/install config) the UserRole can do Basic Operation an VM. Moreover the UserRole is given to the group Everyone on all VM I created, and I can't remove this permission (Remove button is greyed). How can I make a VM "private", only visible by one user ? Thanks in advance, Florent

OVN ACLs
by Niyazi Elvan 10 Jul '18

10 Jul '18

Hi All, I have started testing oVirt 4.2 and focused on OVN recently. I was wondering whether there is a plan to manage L2->L7 ACLs through oVirt web ui. If not, how could it be possible to manage ACLs except command line tools ? Using opendaylight ?? All the best ! Niyazi -- Niyazi Elvan

Device Mapper Timeout when using Gluster Snapshots
by hsahmed＠gmail.com 09 Jul '18

09 Jul '18

I am facing this trouble since version 4.1 up to the latest 4.2.4, once we enable gluster snapshots and accumulate some snapshots (as few as 15 snapshots per server) we start having trouble booting the server. The server enters emergency shell upon boot after timing out waiting for snapshot devices. Waiting a few minutes and pressing Control-D then boots the server normally. In case of very large number of snapshots (600+) it can take days before the sever will boot. Attaching journal log, let me know if you need any other logs. Details of the setup: 3 node hyperconverged oVirt setup (64GB RAM, 8-Core E5 Xeon) oVirt 4.2.4 oVirt Node 4.2.4 10Gb Interface Thanks, Hesham S. Ahmed

hyperconverged cluster - how to change the mount path?
by Liebe, André-Sebastian 09 Jul '18

09 Jul '18

Hi list, I'm looking for an advice how to change the mount point of the hosted_storage due to a hostname change. When I set up our hyperconverged lab cluster (host1, host2, host3) I populated the mount path with host3:/hosted_storage which wasn't very clever as it brings in a single point of failure (i.e. when host3 is down). So I thought adding a round robin dns/hosts entry (i.e. gluster1) for host 1 to 3 and changing the mount path would be a better idea. But the mount path entry is locked in web gui and I couldn't find any hint how to change it manually (in database, shared and local configuration) in a consistent way without risking the cluster. So, is there a step by step guide how to achieve this without reinstalling (from backup)?

Advice on deploying oVirt hyperconverged environment Node based
by Tal Bar-Or 09 Jul '18

09 Jul '18

Hello All, I am about deploying a new Ovirt system for our developers that we plan to be hyperconverged environment Node based. The system workload would be mostly used for builders that compiling our code , which involves with lots of small files and intensive IO. I plan to build two glustered volume "layers" one based on sas drives for OS spin on, and second for Nvme based for intensive IO. I would expect that the system will be resilient/high availability and in the same time give enough good IO request for vm builders that will be at least 6 to 8 vm guests. The system hardware would be as follows: *chassis*: 4x HP DL380 gen8 *each server hardware:* *cpu*: 2x e5-2690v2 *memory*:256GB *Disks*:12x 1.2TB sas 10k disks , 2 mirror for os (or using usk kingstone 2x 128gb mirror) rest for vm os volume. *Nvme*: 2x960GB Kingstone KC1000 for builders compiling source code *Network: *4 ports Intel 10Gbit/s SFP + Given above configuration and theory, my question would be what would be best practice in terms of Gluster configuration *Distributed,Replicated,Distributed Replicated,Dispersed,Distributed Dispersed*? What is the suggestion for hardware raid type 5 or 6 , or use ZFS? Network nodes communication , i intend to use 3 ports for storage communication and one port for guests network , my question regarding Gluster inter communication , what is better would i gail from 3x 10G LACP or 1 network for each gluster volume? Please advice Thanks -- Tal Bar-or

change from LDAP to AD authentication
by p.staniforth＠leedsbeckett.ac.uk 09 Jul '18

09 Jul '18

Hello, as part of our policy I have to change from LDAP to Active Directory for authentication in our oVirt system. I have managed to configure a test system that allows users to login using the CN (sAMAccountName) as before. The users in the system using the AD namespace are using their UPN for their user name. Do we have to copy permissions from all the old accounts to their new accounts or is there a way to rename them to the UPN retaining there old permissions? Thanks, Paul S.

Cannot import a qcow2 image
by etienne.charlier＠reduspaceservices.eu 09 Jul '18

09 Jul '18

Hello, I' m trying without success to import a qcow2 file into ovirt. I tried on a ISCSI datadomain and an nfs datadomain. I struggled quite a lot to have the "test connection" succed ( I write a small shell script to "deploy" letsencryt certificates into ovirt engine) Doc is not clear on the fact that certificates for imageio-proxy are different than for main engine… Now, the upload fails with Transfer was stopped by system. Reason: failed to add image ticket to ovirt-imageio-proxy. Image gets stuck in "transfer paused by system" Any idea ? ovrit is up to date: 4.2.4 on both engine and hosts.

OVN and MTU of vnics based on it clarification
by Gianluca Cecchi 09 Jul '18

09 Jul '18

Hello, I'm testing a virtual rhcs cluster based on 4 nodes that are CentOS 7.4 VMs. So the stack is based on Corosync/Pacemaker I have two oVirt hosts and so my plan is to put two VMs on first host and two VMs on the second host, to simulate a two sites config and site loss, before going to physical production config. Incidentally the two hypervisor hosts are indeed placed into different physical datacenters. So far so good. I decided to use OVN for the intracluster dedicated network configured for corosync (each VM has two vnics, one on production lan and one for intracluster). I detected that the cluster worked and formed (also only two nodes) only if the VMs run on the same host, while it seems they are not able to communicate when on different hosts. Ping is ok and an attempt of ssh session between them on intracluster lan, but cluster doesn't come up So after digging in past mailing list mails I found this recent one: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/RMS7XFOZ67O3ER… where the solution was to set 1400 for the MTU of the interfaces on OVN network. It seems it resolves the problem also in my scenario: - I live migrated two VMs on the second host and rhcs clusterware didn't complain - I relocated a resource group composed by several LV/FS, VIP and application from VM running on host1 to VM running on host2 without problems. So the question is: can anyone confirm what are guidelines for settings vnics on OVN? Is there already a document in place about MTU settings for OVN based vnics? Other particular settings or limitations if I want to configure a vnic on OVN? Thanks, Gianluca

fence_rhevm and ovirt 4.2
by Gianluca Cecchi 08 Jul '18

08 Jul '18

Hello, I'm configuring a virtual rhcs cluster and would like to use fence_rhevm agent for stonith. As VMs composing the 4-nodes cluster I'm using CentOS 7.4 os with fence-agents-rhevm-4.0.11-66.el7_4.4.x86_64; I see that in 7.5 the agent is fence-agents-rhevm-4.0.11-86.el7_5.2.x86_64 but with no modification for the /usr/sbin/fence_rhevm python script apart the BUILD_DATE line. Some questions: - it seems it is still in API v3 even if deprecated; any particular reason? Possible to update to V4? Can I create a RFE bugzilla? This is in fact what I get in engine events registering connection: Client from address "10.4.4.68" is using version 3 of the API, which has been deprecated since version 4.0 of the engine, and will no longer be supported starting with version 4.3. Make sure to update that client to use a supported versions of the API and the SDKs, before upgrading to version 4.3 of the engine. 7/7/184:56:11 PM User fenceuser@internal-authz connecting from '10.4.4.68' using session 'OVgdzMofRFDS4ZKSdL83mRyGUFEdc+++onJHzGiAfpYuS07xa/EbBqFEPtztpwEeRzCn9mBOTGXE69rBbHlhXQ==' logged in. 7/7/184:56:11 PM - UserRole ok Back in April 2017 for version 4.1.1 I had problems and it seems I had to set super user privileges for the "fencing user" See thread here https://lists.ovirt.org/archives/list/users@ovirt.org/message/FS5YFU5ZXIYDC… Now instead I only set UserRole for the defined "fenceuser" on the virtual cluster VMS and it works ok - for a VM with permissions already setup: [root@cl1 ~]# fence_rhevm -a 10.4.192.49 -l "fenceuser@internal" -S /usr/local/bin/pwd_ovmgr01.sh -z --ssl-insecure -o status --shell-timeout=20 --power-wait=10 -n cl1 Status: ON - for a VM still without permissions [root@cl1 ~]# fence_rhevm -a 10.4.192.49 -l "fenceuser@internal" -S /usr/local/bin/pwd_ovmgr01.sh -z --ssl-insecure -o status --shell-timeout=20 --power-wait=10 -n cl2 Failed: Unable to obtain correct plug status or plug is not available - for a VM with permissions already setup: I'm able to make power off / power on of the VM Thanks, Gianluca

08 Jul '18

Hi, can anyone explain differences between Ovirt and RHEV in version 4.1 ? I know that RHEV has diffrent product life-cycle, and there are some diffrences in installation process. Do you know if there are any additional featuers in Ovirt or RHEV ? Do you know any oifficial statements from RH about differences ? From my experience there is not too much diffrences, but I need to prepere such a comaprison for bussines so I would like to get an info from relaiable source. Chris

Ovirt/ RHV Disaster Recovery Designing
by samee095＠gmail.com 07 Jul '18

07 Jul '18

Hi I've looking for some ideas about designing disaster recovery planning with ovirt 4.2. Since 4.2 we have options to have intergration with disaster recovery site also. I went through some videos at internet and want to share if those are correct or not. Thus you can help me regarding what other things I should be having ideas during planning and designing more about this. 1. We've to keep both sites on and already created datacenter, cluster and one site with storage domain attached and other site with no storage domain. 2. We've to keep latency of 10ms at maximum between both sites. 3. Have to configure virtual machines with affinity group. 4. The VM's which are configured as high-available vm, will be migrated first. 5. There's an Ansible script while have to run to fail over and fail back. Now, please could you help me out regarding this. 1. Where can I find this ansible script? Is this https://github.com/oVirt/ovirt-ansible-disaster-recovery.git? 2. Can this script run at rhv also ? or just for ovirt? Or what other changes I have to make for rhv to have this functionalities? 3. How ovirt/rhv works with the OVN compared to NSX? Is there's any challenges ? 4. Can you share me some high and low level diagram related to rhv disaster planning? 5. How the storage migrates on backend ? During the script ? 6. Where do I run this script? During fail over at primary site and during fail back at secondary site? 7. Basically since only the storage migrates and all other components are on already so basically backend it's only dealing with storage migration according to defined policies ? Please could you help me out with some designing and ideas what're the best architecture during planning on disaster recovery at RHV. Thank you.

Is your engine functioning at all? I'm not sure if you're saying your entire engine doesn't work, or just host deploy doesn't work. What version of ovirt engine is this? How did you install -- fresh installation, upgrade? From source or rpm?

ovirt, postfix and sendmail
by Fabrice Bacchella 06 Jul '18

06 Jul '18

ovirt in version 4.2 choose to incorporate postfix as a mandatory MTA: yum erase postfix ... Removing: postfix x86_64 2:2.10.1-6.el7 @base 12 M Removing for dependencies: cockpit-ovirt-dashboard noarch 0.11.28-1.el7 @ovirt-4.2 15 M ovirt-host x86_64 4.2.3-1.el7 @ovirt-4.2 11 k ovirt-hosted-engine-setup noarch 2.2.22.1-1.el7 @ovirt-4.2 2.2 M Is there a way to change that ? It's not about postfix being inferior or superior to other solutions. It's that it didn't ask any thing, didn't check if one was already installed. It's just installed. For example: rpm -q --provides postfix MTA config(postfix) = 2:2.10.1-6.el7 postfix = 2:2.10.1-6.el7 postfix(x86-64) = 2:2.10.1-6.el7 server(smtp) smtpd smtpdaemon rpm -q --provides sendmail MTA config(sendmail) = 8.14.7-5.el7 sendmail = 8.14.7-5.el7 sendmail(x86-64) = 8.14.7-5.el7 server(smtp) smtpdaemon There is a lot of other dependencies to declare other than postfix, MTA would have been better.

Ovirt Networking Setup Questions
by Dave Mintz 06 Jul '18

06 Jul '18

Hello, I am trying to understand, by reading all available docs, how to correctly set up networking. What I have: 6 nodes, 1 engine - all have 3 nics. What I want: To separate traffic into three zones - ovirtmgmt, prod (for vm and admin web interface, data (for db access). So, I have three subnets - 10.10.10.0, 10.10.20.0, and 10.10.30.0 - with matching VLANs 10, 20, 30 I am trying to understand how bonding and bridging work. Should I bond all three nics together? The instructions here: https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/ <https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/> seem to do that and then create two bridges br0 and ovirtmgmt, which they then assign ip addresses to. I can do that, but shouldn’t I be configuring all of the networking at the logical network level? So, in that case, should I just create one bond/bridge and then do all of the networking at the logical level? Sorry if this is newbie stuff. Thanks Dave

Snapshots don't seem to work with Windows VMs
by jmp242＠cornell.edu 06 Jul '18

06 Jul '18

I've been testing with Windows 10 1607 LTSB and created several snapshots. I can preview each one, but they all boot with the same configuration and software installed and files as the "active VM" - so I cannot see at all how to roll back changes. Is this a known issue? I believe I'm following the documentation properly, but I can't see that the snapshots are doing anything. I'm testing on Scientific Linux 7.4 using oVirt 4.2.2.6-1.el7.centos.

oVirt LLDP Labeler
by Ales Musil 06 Jul '18

06 Jul '18

Hello, I would like to announce that oVirt LLDP Labeler is officially available. The Labeler is service that runs along with engine and is capable of labeling host network interfaces according to their reported VLANs via LLDP. The attached labels are named "lldp_vlan_${VLAN}", where ${VLAN} is ID of the corresponding VLAN. This can make work of an administrator easier, because any network with the same label, will be automatically attached to the corresponding host interface. The Labeler is currently tested only with Juniper switches which are capable of reporting all of their VLANs that are present on the interface. We would like to extend the Labeler with auto bonding feature. Those interfaces that are detected on the same switch would be automatically bonded. The Labeler source is available here: https://github.com/almusil/ovirt-lldp-labeler And the build: https://copr.fedorainfracloud.org/coprs/amusil/ovirt-lldp-labeler/ If you have any suggestions or problems please don't hesitate to report them on the GitHub page. -- ALES MUSIL Associate software engineer - rhv network Red Hat EMEA <https://www.redhat.com/> amusil(a)redhat.com IM: amusil <https://red.ht/sig>

GlusterFS 4.1
by Chris Boot 06 Jul '18

06 Jul '18

All, Now that GlusterFS 4.1 LTS has been released, and is the "default" version of GlusterFS in CentOS (you get this from "centos-release-gluster" now), what's the status with regards to oVirt? How badly is oVirt 4.2.4 likely to break if one were to upgrade the gluster* packages to 4.1? Thanks, Chris -- Chris Boot bootc(a)boo.tc

Hello list, I'm using the quick start documentation to build a lab setup. Immediately after the task "Configure Networks", there is a task "Attach oVirt Node or Enterprise Linux Host" I haven't found a spot in the new GUI that matches the navigation tree in the manual. How would I navigate to that task? Thanks. -- Dave Thacker

ovirt-node: freshly installed node: network interfaces not visible
by etienne.charlier＠reduspaceservices.eu 06 Jul '18

06 Jul '18

Hello, I'm deploying a test cluster to get used to the ovirt product. My ovirt ( 4.2.2) engine is deployed in a vmware virtual machine. I'm busy deploying 5 hosts using the ovirt-node iso. I have issue with the additional physical network interface ( used for vm trafic and iSCSI) In ovirt manager I can't see the physical network interfaces. It's thus not possible to assign logical network to physical interfaces and my hosts stays in "non operational" status. How should I configure the additional interfaces in the ovirt-node installer to have them recognized ? I somehow managed to configure one host and I can see a comment line in /etc/sysconfig/network-script/ifcfg-... saying vdsm has acquired the interface.... No Such line in the ifcfg-* file in non operational hosts.... Any idea ? Etienne
