I'm trying to create vlans to mirror my vlans on my external switch. is there a simple way to simply define a port trunk and have ovirt engine pass the traffic on? In VMWare; this can be accomplished by nic teaming/trunking (802.3 ad) and then pass the traffic to the switch. From what I have read in oVirt I need to define ovs switches first; I'd like to simply pass L2 to the switch directly. Regards, Hazen

Host Add - Host not found check DNS or /etc/hosts
by penguin pages 19 Mar '21

19 Mar '21

Fresh install CentOS8 Streams. Gluster wizard runs and deploys. Engine installs on node. I copy over /etc/hosts for primary site resources to ovirt engine so it can find primary cluster nodes without DNS being booted / up at that time. I check ovirt engine can ssh to the three nodes... so as root I generate SSH key and do ssh-copy-id to all three nodes. So as much as I can validate communication is working.. i have. When I "add host" -> use FDN -> input root password But it shows up in GUI host list with "install fails" Only message is : [root@ovirt01 ~]# cat /var/log/ovirt-engine/ansible-runner-service.log 2021-03-18 09:44:15,998 - runner_service.controllers.hosts - DEBUG - Adding host odin.penguinpages.local to group ovirt 2021-03-18 09:44:16,344 - runner_service.services.hosts - ERROR - SSH - NOCONN:SSH error - 'odin.penguinpages.local' not found; check DNS or /etc/hosts 2021-03-18 10:07:15,970 - root - INFO - Analysing local configuration options from /etc/ansible-runner-service/config.yaml 2021-03-18 10:07:15,975 - root - INFO - - setting playbooks_root_dir to /usr/share/ovirt-engine/ansible-runner-service-project 2021-03-18 10:07:15,975 - root - INFO - - setting ssh_private_key to /etc/pki/ovirt-engine/keys/engine_id_rsa 2021-03-18 10:07:15,975 - root - INFO - - setting port to 50001 2021-03-18 10:07:15,975 - root - INFO - - setting target_user to root 2021-03-18 10:07:15,975 - root - INFO - - setting log_path to /var/log/ovirt-engine 2021-03-18 10:07:15,975 - root - INFO - Analysing runtime overrides from environment variables 2021-03-18 10:07:15,975 - root - INFO - No configuration settings overridden 2021-03-18 10:07:15,995 - root - INFO - Loaded logging configuration from /etc/ansible-runner-service/logging.yaml 2021-03-18 10:07:16,004 - runner_service.controllers.hosts - DEBUG - Request received, content-type :None 2021-03-18 10:07:16,005 - runner_service.controllers.hosts - INFO - 127.0.0.1 - GET /api/v1/hosts/thor.penguinpages.local 2021-03-18 10:07:16,013 - runner_service.controllers.hosts - DEBUG - Request received, content-type :application/json; charset=UTF-8 2021-03-18 10:07:16,013 - runner_service.controllers.hosts - INFO - 127.0.0.1 - POST /api/v1/hosts/thor.penguinpages.local/groups/ovirt 2021-03-18 10:07:16,013 - runner_service.controllers.hosts - DEBUG - additional args received 2021-03-18 10:07:16,014 - runner_service.controllers.hosts - DEBUG - Adding host thor.penguinpages.local to group ovirt 2021-03-18 10:07:16,339 - runner_service.services.hosts - ERROR - SSH - NOCONN:SSH error - 'thor.penguinpages.local' not found; check DNS or /etc/hosts 2021-03-18 10:07:38,333 - runner_service.controllers.hosts - DEBUG - Request received, content-type :None 2021-03-18 10:07:38,334 - runner_service.controllers.hosts - INFO - 127.0.0.1 - GET /api/v1/hosts/thor.penguinpages.local 2021-03-18 10:07:38,339 - runner_service.controllers.hosts - DEBUG - Request received, content-type :application/json; charset=UTF-8 2021-03-18 10:07:38,339 - runner_service.controllers.hosts - INFO - 127.0.0.1 - POST /api/v1/hosts/thor.penguinpages.local/groups/ovirt 2021-03-18 10:07:38,339 - runner_service.controllers.hosts - DEBUG - additional args received 2021-03-18 10:07:38,340 - runner_service.controllers.hosts - DEBUG - Adding host thor.penguinpages.local to group ovirt 2021-03-18 10:07:38,713 - runner_service.services.hosts - ERROR - SSH - NOCONN:SSH error - 'thor.penguinpages.local' not found; check DNS or /etc/hosts But ssh is fine to all hosts works fine.

Quick Question: Degraded Gluster
by Christian Reiss 18 Mar '21

18 Mar '21

Hey folks, quick question: I have a 3 node cluster (HC) in a production environment. I recently swapped all the storage SSDs with bigger enterprise grades SSDs. So I took a host down (migrating all VMs away, maintenance, shutdown, fix raid, gluster repair, back online). This worked well and all three nodes are now hardware-wise replaced. The last one is still gluster-healing (roughly 20% done). The other two nodes are happily serving the vms while the third one is still in maintenance. my question is: Can I online the maintenance node while gluster is still healing? Or will will open up a can of worms I would not like? It would be cool having all three nodes back online soon while the gluster is still repairing. We have no urge tho. If there is a risk I would wait. If this is somewhat risk-free and do-able why not :) -- with kind regards, mit freundlichen Gruessen, Christian Reiss

by Lev Veyde 18 Mar '21

18 Mar '21

oVirt 4.4.5 is now generally available The oVirt project is excited to announce the general availability of oVirt 4.4.5 , as of March 18th, 2021. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>.

4.4.5 released? Fails to upgrade
by Rik Theys 18 Mar '21

18 Mar '21

Hi, My systems pulled in 4.4.5 packages last night, so I assume oVirt 4.4.5 was released? The release notes page does not list the release and I also did not see any announcement. The packages are 4.4.5.10-1.el8. I ran an engine-setup and upgraded to this release but the upgrade has failed due to a failure to update the database schema and it seems the rollback was not successful as my instance failed to start afterwards. I've downgraded all packages and ran engine-setup --offline, which seems to at least bring back my engine to a working state. I'm confused: has 4.4.5 been released or did I pull in some intermediate version with known issues? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept. Elektrotechniek (ESAT) Kasteelpark Arenberg 10 bus 2440 - B-3001 Leuven-Heverlee +32(0)16/32.11.07 ---------------------------------------------------------------- <<Any errors in spelling, tact or fact are transmission errors>>

Access to the internet from oVirt VMs
by unityresearcher＠alterpost.org 16 Mar '21

16 Mar '21

Hi to all ✋😉 I've stacked with ovirt's vm network routing Infrastructure: 1. stansalone ovirt engine (hetzner cloud vm) 2. ovirt node (hetzner robot, dedicated server) 3. hetzner private cloud network. Both Engine and Node are connected to private network. For node the network is built on external NIC's tagged VLAN https://docs.hetzner.com/robot/dedicated-server/network/vswitch/ 4. Also there is a pfsense router vm in private network So my purpose is to grant access to the internet from VM inside oVirt via pfSense. Additional info: 1. pfsense machine is pingable from oVirt VM 2. oVirt VM NIC – ovirtmgmt 3. pfsenses' NAT works fine for machines in hetzner cloud 4. Painful troubleshooting showed that something on ovirtmgmt bridge forbids to route traffic to another network 5. Internet access "from the box" doesn't work because ovirtmgmt works on VLAN interface, not at physical one itself. 6. In Ovirt's docs I've found the two ways of custom routing. The first one is about external network provider, that unacceptable for me because it doesn't support VLAN tagging (without it node's network can't get access to private cloud network). The second one is custom routing inside a node that doesn't work for me as well by unknown reason What I do wrong? What are the best practices in oVirt network when we talking about internet access from oVirt's VMs? Thx 😉

Reset NVRAM
by Shantur Rathore 15 Mar '21

15 Mar '21

Hi all, I am doing some testing with GPU passthrough to VMs and in some cases the OVMF stops booting after a GPU passthrough. I have figured out that it's related to some state stored in NVRAM by OVMF and as soon as I create another VM with the same disks it starts booting up. I believe oVirt saves the NVRAM state. Is there a way to clear NVRAM for a VM without deleting it? Regards, Shantur

4.4.5 Release timeline
by David White 15 Mar '21

15 Mar '21

Hello, Reviewing https://ovirt.org/release/4.4.5/, I see that the target release date was set to March 9. However, glancing at https://bugzilla.redhat.com/buglist.cgi?quicksearch=ALL%20target_milestone%…, I see a number of outstanding open tickets. Do the maintainers anticipate that 4.4.5 will be released soon? I'm trying to decide if I should wait for 4.4.5 to be released, or if I should go with 4.4.4, as I am getting ready to do a fresh install for a 3-node hyperconverged cluster, and need to begin setting up VMs and configuring things very soon.

RHV is allocating more space than it should
by Łukasz Kołaciński 15 Mar '21

15 Mar '21

Hello, I have a question about restoring virtual machines. Why is ovirt/rhv allocating ~10% more space than it should. For example, we have a 10 GB disk, and after restore the size is 11 GB. This only happens with a SPARSE disk type on ISCSI storage. Is it a normal behavior?

Unsure where to post this
by Jason Alexander Hazen Valliant-Saunders 14 Mar '21

14 Mar '21

Hello Ovirt Users; I'm attempting to Deploy Ovirt-engine and having a rough go of it with 4.4.4 I've installed oVirt 4.4.4 onto a USB key (64GB) on an HP DL 380 G8, Storage is via NFS and Free NAS (30TB) over 10GB Ethernet (Chelsio) - I had to install drivers using these commands: Chelsio T320 10GB/s Card Mods 1. rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 2. yum install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm 3. yum install kmod-cxgb3 for some reason I've had services failing on my Newly installed Ovirt Node The oVirt Imiage IO Deamon refuses to start: I believe this is the reason I cannot run "hosted-engine --deploy" (fails towards the end) For a bit it was the VSDM service now it's the image IO Deamon. intuition tells me that maybe Ovirt does not play well with Chelsio 10GB cards?? As always any help is appreciated. Regards, Hazen

Gluster volume engine stuck in healing with 1 unsynched entry & HostedEngine paused
by souvaliotimaria＠mail.com 11 Mar '21

11 Mar '21

Hello everyone, Any help would be greatly appreciated in the following problem. In my lab, the day before yesterday, we had power issues, with a UPS going off-line and following the power outage of the NFS/DNS server I have set up to serve ovirt with isos and as a DNS server (our other DNS servers are located as VMs within the oVirt environment). We found a broadcast storm on the switch (due to a faulty NIC on the aformentioned UPS) that the ovirt nodes are connected and later on had to re-establish several of the virtual connections as well. The above led to one of the hosts becoming NonResponsive, two machines becoming unresponsive and three VMs shuting down. The oVirt environment, version 4.3.5.2, is a replica 2 + arbiter 1 environment and runs GlusterFS with the recommended volumes of data, engine and vmstore. So far, the times there was some kind of a problem, usually oVirt was able to solve it by its own. This time, however, after we recovered from the above state, the volumes of data and vmstore successfully healing , the volume engine became stuck to the healing process (Up, unsynched entries, needs healing), and from the web GUI I see that the VM HostedEngine is paused due to a storage I/O error while the output of virsh list --all command shows that the HostedEngine is running.. How is that happening? I tried to manually trigger the healing process for the volume but nothing with gluster volume heal engine The command gluster volume heal engine info shows the following [root@ov-no3 ~]# gluster volume heal engine info Brick ov-no1.ariadne-t.local:/gluster_bricks/engine/engine Status: Connected Number of entries: 0 Brick ov-no2.ariadne-t.local:/gluster_bricks/engine/engine /80f6e393-9718-4738-a14a-64cf43c3d8c2/images/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7 Status: Connected Number of entries: 1 Brick ov-no3.ariadne-t.local:/gluster_bricks/engine/engine /80f6e393-9718-4738-a14a-64cf43c3d8c2/images/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7 Status: Connected Number of entries: 1 This morning I came upon this Reddit post https://www.reddit.com/r/gluster/comments/fl3yb7/entries_stuck_in_heal_pend… where it seems that after a graceful reboot one of the ovirt hosts, the gluster came back online after it completed the appropriate healing processes. The thing is from what I have read that when there are unsynched entries in the gluster a host cannot be put into maintenance mode so that it can be rebooted, correct? Should I try to restart the glusterd service. Could someone tell me what I should do? Thank you all for your time and help, Maria Souvalioti

Hi, When trying to pin a VM CPU's to Physical CPU's, I'm getting this error in case the number of physical CPU slots are > 35 (e.g. 40): Error attempting to pin CPUs. Full error: Fault reason is "Operation Failed". Fault detail is "[size must be between 0 and 4000, Attribute: vmStatic.cpuPinning]". HTTP response code is "400". HTTP response message is "Bad Request". It is working for me up to 35 physical CPU's. but above it, I get that error. Can you please tell what this error means and how to overcome it? Version we are using is: 4.3.6.6-1.0.9.el7 Thanks, Lavi

How to replace a failed oVirt Hyperconverged Host
by Ramon Sierra 10 Mar '21

10 Mar '21

Hi, We have a three hosts hyperconverged ovirt setup. A few weeks ago one of the hosts failed and we lost a RAID5 array on it. We removed it from the cluster and repaired. We are trying to setup and add it back to the cluster but we are not clear on how to proceed. There is a replica 2 with 1 arbiter Gluster setup on the cluster and I have no idea on how to recreate the LVM partitions, gluster bricks, and then add it to the cluster in order to start the healing process. Any help on how to proceed with this scenario will be very welcome. Ramon

oVirt 4.3.6 and Security Measures
by scroodj＠gmail.com 10 Mar '21

10 Mar '21

Hello team, Due to security policy in the our customer`s company there is need to implement some changes into machines in their oVirt cluster (Standalone Engine + 2 KVM Host). 1. The home drives of user sanlock (/var/run/sanlock) and gluster (/run/gluster) have permission of 775. We would like to have them at least 755 if not stricter. Is that possible? 2. NFS mount of storage has ‘nodev’ and ‘nosuid’ disabled. Is it safe to use those options for NFS Storage doamin? 3. Usually bridged routing is not allowed on managed servers. Security scan asks us to set the following four parameters to 0 Network Parameter "net.ipv4.conf.all.send_redirects" = 1 (expected: 0) Network Parameter "net.ipv4.conf.all.secure_redirects" = 1 (expected: 0) Network Parameter "net.ipv6.conf.all.accept_redirects" = 1 (expected: 0) Network Parameter "net.ipv4.conf.all.accept_redirects" = 1 (expected: 0) Would changing them interfere with ovirtmgmt network? Those are valid for all three machines in the cluster. On the engine though there is httpd installed now and we have some findings there too: 1. There are modules installed that are on a blacklist. Can they be removed? The modules are: mod_dav_lock mod_userdir mod_include mod_dav_fs mod_autoindex mod_dav mod_info 2. HTTP traces should be blocked so we would set “TraceEnable” to off in virtual host config. If HTTP traces are needed we would have to limit the verbs that are allowed. 3. Apache version information should be turned off to not inform potential attackers of which web server is running. Is that a problem for oVirt? 4. TLSv1.0 and TLSv1.1 are enabled but should be turned off. 5. HSTS should be turned on but is not yet. 6. Can we use X-Frame-Options header to append X-Frame-Options DENY (or SAEMORIGIN or at least ALLOW-FROM)? 7. Can we implement the X-Content-Type-Options HTTP header with “nosniff”? 8. Can we implement the X-XSS-Protection header with “1; mode=block”? I know, this is quite a bit. But maybe you know the answers. BR Aleksandr
