Adding custom network filter to oVirt
by Peter 01 Aug '18

01 Aug '18

I can see from the libvirt docs how to create a new network filter (to block STP broadcasts in my case), but how do I add that filter to the vNIC list in oVirt?

I think we are in a race to see who can get a new HCI setup built faster.

Migrating Legacy Hyperconverged Legacy switch type to OVS
by Mike 01 Aug '18

01 Aug '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
by Hari Prasanth Loganathan 31 Jul '18

31 Jul '18

Hi Team, 1) I use the following oVirt API to attach the ISO image to the virtual machine.

Hosted Engine deploy failed on new HCI build
by Jayme 31 Jul '18

31 Jul '18

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,

Upgrade from 4.1 to 4.2 failing - SQL Issues
by Sven Achtelik 31 Jul '18

31 Jul '18

Hi All, I'm still struggling to upgrade from 4.1 to 4.2 and the root cause seems to be the SQL upgrade. I installed my 4.1.9 with the engine appliance image and restored a DB to it. My Upgrade to 4.2 is failing with the errors below: -------------------------------- Performing Consistency Checks ----------------------------- Checking cluster versions ok Checking database user is the install user ok Checking database connection settings ok Checking for prepared transactions ok Checking for reg* system OID user data types ok Checking for contrib/isn with bigint-passing mismatch ok Checking for invalid "line" user columns ok Creating dump of global objects ok Creating dump of database schemas engine ovirt_engine_history postgres template1 ok encodings for database "template1" do not match: old "UTF8", new "SQL_ASCII" Failure, exiting I tried everything that could do and I also tried to find a solution on google to make this work. Could someone with DB knowhow please advise on the next steps to resolve this ? I really would like to upgrade somehow. Thank you, Sven

adding hosts problems with GlusterFS
by william.dossett＠gmail.com 30 Jul '18

30 Jul '18

Hi, I setup my 3 host HCI cluster and things are going pretty good. I have a few issues though... one of them is that I added two more hosts to the three node cluster to make it a 5 nodes. This seemed to work fine until I went to create bricks. I have 6 x 2 TB disks for use as JBOD in each node. After I added the nodes, I went to the host and storage devices. This looks significantly different that the view on my first 3 hosts. On the two new hosts all my drives sdb - sdg have locks next to them and file system type is multipath__member. Further up the page then I see a UID under the name and description is PERC H710P dm-multipath - no lock next to it. I created a brick on this and it created the lvmpv file system, however when I go to bricks view, there are no bricks. So, did I make a mistake while adding the hosts? is there some way to prevent this dm-multipath configuration? Thanks Bill

Re: adding hosts problems with GlusterFS
by Bill Dossett 30 Jul '18

30 Jul '18

Hmm, resounding silence.... Have attached a screen shot of the host storage devices on the host I added after the initial deployment. So at the bottom you can see that sdb - sdg are all locked and FS type is multipath_member those all equate to the UID type NAME at the top. The very top row, I created a brick, so it is also now locked, however when I go to brick view there is no brick. I also can't seem to delete any brick one it is created either. On the first 3 hosts, sdb - sdg are all unlocked and I can create bricks... going to remove a host and re-add it to see if there is anything I am missing, but I don't have any other ideas at this point.

up and running with ovirt 4.2 and gluster
by william.dossett＠gmail.com 30 Jul '18

30 Jul '18

Hi, I have my ovirt 4.2 hci cluster up and running, but I have a probably stupid question. During the setup and in the documents it defaults to setting up the engine datastore/volume, a VMstore/volume and a data/volume. What is the Data volume for? I am planning on running VMs on this so I would assume I need VMstore and that's what I will grow on my system. In previous installs you had the opportunity to create the ISO domain, but not now. I can see how to create in the engine UI so that's fine, but I am just wondering what people use the Data volume for as an example. Thanks Bill

Import Netapp snapshot volume into ovirt and start VM from volume snapshot
by Igor Zinovik 30 Jul '18

30 Jul '18

Hello. I'm trying to implement following backup scenario for my VMs: storage domain is a volume on netapp appliance connected to oVirt cluster via NFS3. Netapp produces its zero copy snapshots of this volume. I want to be able to restore VMs from these snapshots, e.g. Netapp can export snapshot to ovirt as another NFS volume after that I want to be able to import VM or attach VM disks from snapshot volume to VM and start it. As far as I understand it is basic backup|migration scenario when user wants to move VMs from one ovirt DC to another ovirt DC. Right now I cannot import snapshot volume which contains exactly same domain metadata (in dom_dm/ directory) as original volume (which I cannot detach since it hosts disks for running VMs). I tried to rename dom_md/, but with no success in domain import process. Maybe someone in this list uses same scenario for VM backup and can give some advice.

---------- Forwarded message --------- From: Jayme <jaymef(a)gmail.com> Date: Sun, Jul 29, 2018, 10:09 PM Subject: Re: [ovirt-users] Re: up and running with ovirt 4.2 and gluster To: Mike <xenithorb(a)fedoraproject.org> On this same subject one thing I'm currently hung up on re: HCI setup is the next step in the cockpit config for glusterfs. I have three nodes setup with two drives each in jbod. On the brick config screen you have to specify the device location and size of each of the volumes you configure on the previous step i.e engine and data. It seems that I can only specify one of my drives for the data volume. So I'd have to pick /dev/SDA drive for engine and /dev/sdb for data, but I have 2x2tb drives what do I do with all the other space on the devocd I put the engine volume on? If I choose to use sdb for data and have it 1.8tb does that mean the data storage will only use one single drive in each of my three nodes? I want to make use of all six drives to increase I/o performance. I don't understand how the jbod config of gluster is suppose to work. What if I had even more drives in each node say 4 separate drives how would I make use of all drives when I can only specify one device for each volume? I'm thinking about creating a data and data2 volume and specifying SDA for data and sdb for data2. Am I completely misunderstanding the setup here. Its very confusion and there is next to no documentation on HCI available.

Hosted engine unaviable after storage rebuild
by sebastian.w＠gmx.ch 29 Jul '18

Hello all, My hosted engine does not start up anymore, because the node can't reach the storage. The hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable. What happend is that my NAS crashed and I had to rebuild it from the backup. I'm quit sure that I called all the NFS shares the same way as they bevore the issue. How can I figure out whats the issue with the storage? The logs wheren't realy helpful for me (but may it's me and not the logs to blame) Regards and thanks Sebi

Changing Network Interfaces on host causes bond to go offline
by oBSD Nub 29 Jul '18

29 Jul '18

Everytime I try to change assigned Logical networks (add ip addresses, assign a logical network, etc) the bond0 interface winds up going down. I have to do a ifup bond0 from the console, and the engine reconnects. After a lot of digging, I think this is the offending command, but I don't know how to read it or next troubleshooting steps. Anyone want to point me in the right direction?
