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?

Re: adding hosts problems with GlusterFS

I think we are in a race to see who can get a new HCI setup built faster. There have been a few hurtles along the way :) On Tue, Jul 31, 2018, 6:53 AM Bill Dossett, <bill.dossett(a)pb.com> wrote: > Hmm, resounding silence….

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
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. URL: https://X.X.X.X/ovirt-engine/api/vms/625871af-180c-4e63-8813-93963907ed17/c… <https://172.30.60.45/ovirt-engine/api/vms/625871af-180c-4e63-8813-93963907e…> Method Type : POST *PUT DATA* : { "file": { "id": "Windows_7_64-bit_Professional_x64 SP1.iso" } } 2) But If I want to assign the virtual floppy disk to the virtual machine, like below, *Is there a way to attach it*? URL: https://X.X.X.X/ovirt-engine/api/vms/625871af-180c-4e63-8813-93963907ed17/c… <https://172.30.60.45/ovirt-engine/api/vms/625871af-180c-4e63-8813-93963907e…> Method Type : POST *PUT DATA* : { "file": { "id": "virto-win.vdf" } } *NOTE*: I am able to set the boot sequence using oVirt UI, like below, where I am able to attach the virtual Floppy Disk and as well as ISO image. -- DISCLAIMER - *MSysTechnologies LLC* This email message, contents and its attachments may contain confidential, proprietary or legally privileged information and is intended solely for the use of the individual or entity to whom it is actually intended.

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!
