Re: External ceph storage

No, The only way you have is to configure cinder to manage ceph pool or in alternative you have to deploy an iscsi gateway, no other ways are available at the moment. So you can't use rbd directly.

oVirt node 4.2.x - custom multipath.conf and external storage availability
by Roberto Nunin 13 Aug '18

13 Aug '18

HI all How can I provide to my oVirt hosts a custom multipath.conf, considering that we are using shared/mirrored FC storage from HPE 3PAR with high availability of provided LUNs, using peer-persistance feature ? To configure correctly this require a custom multipath.conf is required. How I can avoid it will be overwritten during upgrades ? Second topic: Is ALUA feature supported also in oVirt nodes, like for standard RHEL 6/7 and/or CentOS 6/7 ? I was digging for a while into user's digest, but not able to find focused informations. This is the feature needed by peer-persistance, allowing two different volumes to be masked toward a given host with the same WWN and LUN number. Thanks in advance -- Roberto

Drive letter / scsi id not consistent
by Nathan March 08 Aug '18

08 Aug '18

Hi, Managing disks in the ovirt gui seems completely error prone since the GUI ordering does not seem to be used in any practical way. The scsi ID's are not exposed via the GUI either, so if you have 2 drives of the same size on NFS there's no way to identify which is which without resorting to dumping the xml. I see in the xml that the target dev is correct and matches up with the GUI's drive order, but the scsi unit seems to be generated based on the order of last activated: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='scsi0-0-0-3'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> After deactivating the other 2 disks and rebooting the machine, sda has now become unit 3: <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> and then I shutdown, activated the extra 2 drives, booted it back up but now I'm still on unit 3: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/b622cde9-ffc4-487b-8038-f7cb7fbc00a1/7240b4b2-5ab1-40ab-99bb-09c69fd835f6'/> <backingStore/> <target dev='sda' bus='scsi'/> <serial>b622cde9-ffc4-487b-8038-f7cb7fbc00a1</serial> <boot order='1'/> <alias name='ua-b622cde9-ffc4-487b-8038-f7cb7fbc00a1'/> <address type='drive' controller='0' bus='0' target='0' unit='3'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/86765f60-4240-44f4-b437-f22b2cc3df1a/482a363e-461a-4f37-876c-43ceb529a93a'/> <backingStore/> <target dev='sdb' bus='scsi'/> <serial>86765f60-4240-44f4-b437-f22b2cc3df1a</serial> <alias name='ua-86765f60-4240-44f4-b437-f22b2cc3df1a'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/> <source file='/rhev/data-center/mnt/10.1.32.10:_sas01/2060a19f-f26c-4dba-a559-83541a4d0c7a/images/0b020d24-3dea-4be7-931a-9c25ccfeec48/7e3957ff-a3bf-4080-a7b6-ddad7f63a299'/> <backingStore/> <target dev='sdc' bus='scsi'/> <serial>0b020d24-3dea-4be7-931a-9c25ccfeec48</serial> <alias name='ua-0b020d24-3dea-4be7-931a-9c25ccfeec48'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> I managed to get things into the correct state by shutting down the VM, deactivating all the disks, then activating them in the order I want them to show up. This sets the correct order of unit 0 for sda, unit 1 for sdb, unit 2 for sdc. Is there some way to make ovirt treat this in a sane way and always expose the scsi devices in the same order as the GUI (and the "target dev" field)? Cheers! Nathan

better understand ovirt-engine functions
by stuartk＠alleninstitute.org 07 Aug '18

07 Aug '18

I've been reading through documentation https://www.ovirt.org/documentation/architecture/architecture/ https://www.ovirt.org/documentation/self-hosted/Self-Hosted_Engine_Guide/ But am struggling still to understand the role ovirt-engine plays. Would anyone have recommends for additional reads? The problem I'm tackling currently looks like this: - We have (2) oVirt Data Centers, each populated by a single Cluster. The Data Centers are physically & network-wise 'distant' from one another - hosted-engine runs on (3) of the (4) Hosts in Data Center A / Cluster A. hosted-engine does not run on Data Center B / Cluster B - When we disrupt network connectivity around Cluster A (yes, that's Cluster *A*), Hosts in Cluster B crash (requiring a power cycle) and Guests in Cluster B get stopped and paused I'm struggling to understand why mussing with Cluster A affects Cluster B. From pcaps, I can see plenty of TLS traffic from Cluster A's Hosts -- presumably from ovirt-engine running on Cluster A -- exchanged with Cluster B. So, during my last maintenance window, I put hosted-engine into maintenance mode ... but Hosts/VMs in Cluster B were still affected. Where do I go to better understand what ovirt-engine does when it is 'managing' Hosts & VMs? --sk

MoM - Not working ? How to use it ?
by jeanbaptiste＠nfrance.com 07 Aug '18

Hello, I'm trying to test Memory balloon useful functionality, but l'm unable to make it work successfuly. Firstly, I enable the MOM on my Cluster: Memory Balloon Enable Memory Balloon Optimization Secondly, I configure a VM virtual machine like this: On system tab: Memory Size : 28672 MB Maximum memory : 28672 MB On Ressource allocation tab: Memory Allocation: Physical Memory Guaranteed : 2048 MB Memory Balloon Device: Enabled Thirdly, I test 1- I boot the VM. After boot VM consume 200MB 2- I lauch perl program which consume 26GB. 3- During this, Host RAM usage is near 90% 4- I stop the perl program, and on guest side, RAM usage drop down to 200Mo 5- On host side, RAM usage keep to 24 - 26GB. I wait some time to show if the qemu-vm process drop is host-ram-usage. Ram usage keep to 24GB. 6- I try to launch another VM like the first one (but with 8GB RAM and 2GB Guaranteed) , on the host (to "force" Mom ?) but I'm unable to lauch it, Host free mem is insufficient I change MoM log to debug to show something: 2018-07-31 11:49:31,887 - mom.RPCServer - INFO - ping() 2018-07-31 11:49:31,888 - mom.RPCServer - INFO - getStatistics() 2018-07-31 11:49:31,888 - mom.Monitor - DEBUG - Field 'mem_free' not known.

Unable to revive host after a reboot
by Julius Schwartzenberg 03 Aug '18

03 Aug '18

Hi, I recently had to shutdown my oVirt system which contains both the engine and the host. After it came back up, the host was not able to initialize anymore from the oVirt UI. First it kept getting stuck in a loop with setting "ExecutingStarted: Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode." This was being repeated over and over again. It also gave this error: Host pc331 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' Even though I am using that interface (ovirtmgmt) to access the system and 'ip addr show' shows that it's set up properly. I tried some more things, including upgrading the host, When I do that, the status changes to 'Installing' and later to 'Install Failed'. Here are the engine.log, vdsm.log and ovirt-host-deploy*.log: https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI https://drive.google.com/open?id=10Zm2dDpxM2k5A2bEs_l6gOv_yWv4cjlN https://drive.google.com/open?id=1AieWMzRuA0gZj3x5yDH1AGnsT2E3VtOM Any idea what is going wrong (what I'm doing wrong) and how to solve it?

Hi All, In the restapi of version 3, there is bootable attribute in disk. But in version 4, the bootable attribute is removed from disk. For vm i can get bootable attribute from diskattachment. But there is no diskattachment in template. So, is there any way in the restapi of version 4 that i can know if the disk of the template is bootable or not? Thanks Regards. like.ma(a)cs2c.com.cn

Data Recovery from snapshot
by Jim Kusznir 01 Aug '18

01 Aug '18

Hi: With yet another gluster disk failure / gluster collapse, it appears I lost the "main" backing image for one of my vm servers. I have snapshots still in tact (or at least, appear to be), but the main image is gone. The main server process stores a backup at regular intervals in its disk, and that would have been changed data, so it would be in the snapshot rather than the base image. Is there any way to recover this one .tar.gz file from the snapshot with the missing main image? This is a backup of dynamic data, and without it, I will have lost several customers data, some of which cannot be recreated/regenerated. it also appears that my backup (gluster geo-replication) did not work (had crashed a while ago, and has a very old backup of this image). --Jim

Migrating Legacy Hyperconverged Legacy switch type to OVS
by Mike 31 Jul '18

31 Jul '18

Spent the better part of a day trying to figure out how to bridge OVN networks with physical networks, only to later find out that "Attach to physical network" has zero effect in a Legacy cluster... which started me down the rabbit hole of "how do I switch the Default cluster to be OVS" Then, I come up with the bright idea that I'm going to create a new OVS cluster and migrate all the hosts there, well in order to do that you might: 1. Put the Host into maintenance 2. Install to UNDEPLOY the hosted engine 3. Remove the host from the cluster 4. Add the host to the new OVS cluster However this has a nasty bug where the required networks won't ever sync I believe because of some QoS settings (even though I haven't set that), so host is not able to reach gluster storage, and this was not one of the 3 replicas, it was just a client So moving on just to test the waters with another angle, I UNDEPLOY on one of the gluster servers, and then and only then after waiting however long it took to install/undeploy, does it tell me that It can't remove this host from the cluster because it holds gluster volumes......... How in the heck can I migrate what I have on Default to use native OVS? Let's say I started fresh (I'm using oVirt Node 4.2.5) since I have that option....I don't ever recall there being an option to select OVS as the hosted-engine switch type, and it of course sets up the Default cluster for you - which is the one I'm having issues with because it's legacy by default. Thanks

AAA question...takes long time to log in
by sipandbite＠hotmail.com 31 Jul '18

31 Jul '18

I work at a company with a massive AD infrastructure. Is there any way to specify a specific OU to search through instead of just providing a top level DN? We use sssd for all our authing needs on our linux machines and would like to do something like below: ldap_user_search_base = OU=Employees,OU=blah users,DC=blah,DC=com enumerate = false When I connect on cli it looks like Ovirt is reaching out and grabbing a ton of info it doesn't really need. It takes on average 40 second to allow me to log in on CLI or UI. This is not an AD issue as we use AD on everything in our labs and have no issues with speed. I applied these changes and it didn't speed anything up. https://ovirt.org/develop/release-management/features/infra/aaa_faq/ I can see from a tcpdump that I am in fact hitting my local AD servers and not going across the world to get an answer. Thanks!

Direct LUNs and VM Pauses
by Ryan Bullock 31 Jul '18

31 Jul '18

Hello All, We recently stood up a new Ovirt install backed by an ISCSI SAN and it has been working great, but there are a few quirks I am trying to iron out. We have run into an issue where when we fail-over our SAN (for maintenance, or otherwise) any VM with a Direct LUN gets paused and doesn’t resume. VMs without a direct LUN never paused. Digging through posts on this list and reading some bug reports, it seems like this a known quirk with how Ovirt handles Direct LUNs (it doesn't monitor the LUNs and so it wont resume the VM). To get the VMs to automatically restart I have attached VM leases to them and that seems to work fine, not as nice as a pause and resume, but it minimizes downtime. What I’m trying to understand is why the VMs with Direct LUNs paused, and ones without didn’t. My only speculation is that since the Non-Direct is using LVM on top of ISCSI, that LVM is adding its own layer of timeouts that cause it to mask the outage? My other question is, how can I keep my VMs with Direct LUNs from pausing during short outages? Can I put configurations in my multipath.conf for just the wwids of my Direct LUNs to increase the ‘no_path_retry’ to prevent the VMs from pausing in the first place? I know in general you don’t want to increase the ‘no_path_retry’ because it can cause timeout issues with VDSM and SPM operations (LVM changes, etc). But in the case of a Direct LUN would it cause any problems? Thank you, Ryan

Extended DPDK support in oVirt[0]
by Leon Goldberg 31 Jul '18

31 Jul '18

Hi, oVirt support for DPDK was introduced in 2017[1], and is now enhanced in terms of deployment via Ansible[2] and usage via OVN. Compatible hosts and NICs can now be easily configured to use userspace drivers, while usage is enhanced via OVN, allowing for both increased performance and SDN usability. For additional information and instructions, please refer to this blog post[0].

API for attaching the ISO image and virtual floppy disk to the VM

Hosted Engine deploy failed on new HCI build

Latest version of oVirt node 4.2 installed on three hosts. I completed successfully the cockpit gdeploy process to deploy HCI. All of that went well with no errors. I then proceeded to the hosted engine deployment step which eventually failed (log attached). This is the current status: --== Host 1 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : MASKED Host ID : 1 Engine status : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : 3fa48e03 local_conf_timestamp : 8468 Host timestamp : 8468 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=8468 (Mon Jul 30 14:21:09 2018) host-id=1 score=3400 vm_conf_refresh_time=8468 (Mon Jul 30 14:21:09 2018) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False If I do hosted-engine --console I get: The engine VM is running on this host Connected to domain HostedEngine Escape character is ^] error: internal error: cannot find character device <null> does anyone know why it may have failed or what I could do to recover from this? I'm thinking it could have potentially failed due to some problem with network config. If I could get a console in to the engine VM I might be able to fix it but that serial error above is preventing me from reaching the vm console to diagnose further. Log of deploy attached: Thanks!

NFS Mount on EMC VNXe3200 / User - Group 36:36 / Permission issue
by jeanbaptiste＠nfrance.com 31 Jul '18

31 Jul '18

Hello, I try to mount an NFS Data share from a EMC VNXe3200 export. Unfortunately, NFS share cannot be mount, there is permission error. (Indeed, after the same issue on another NFS ISO repo, I’ve change exported directory user/group to 36:36, and O-Virt NFS mount was great). So, I think issue with my VNXe3200 is regarding UID / GID owner on VNXe3200 side. After webex with EMC support, change owner / permission on VNXe side seems not possible / supported. Can I mount the NFS share with some options to avoid vdsm:kvm mounting issue ? Can I force mount with root ? Regards, Jean-Baptiste,
