Guest don't start : Cannot access backing file

Hi, i've a big problem, i juste shutdown (power off completely) a guest to make a cold restart. And at startup the guest say : "Cannot access backing file '/rhev/data-center/mnt/blockSD/69348aea-7f55-41be-ae4e-febd86c33855/images/8224b2b0-39ba-44ef-ae41-18fe726f26ca/ca141675-c6f5-4b03-98b0-0312254f91e8'" When i look from shell on Hypervisor the device file is red blinking... Trying to change SPM, look device into all hosts, copy disk etc... no way to get my disk back online. It seems ovirt completely lost (delete?) the block device. There is a way to manually dump (dd) the device in command line in order to import it inside ovirt? My environment Storage : SAN (managed by ovirt) Ovirt-engine 4.4.3.12-1.el8 Host centos 8.2 Vdsm 4.40.26 Thanks for help i'm stuck and it's really urgent -- Lionel Caignec

3 node cluster. Gluster for shared storage. CentOS8 Updated to CentOS 8 Streams :P -> https://bugzilla.redhat.com/show_bug.cgi?id=1911910 After several weeks ..

VG issue / Non Operational
by Christian Reiss 18 Jan '21

18 Jan '21

Hey folks, quick (I hope) question: On my 3-node cluster I am swapping out all the SSDs with fewer but higher capacity ones. So I took one node down (maintenance, stop), then removed all SSDs, set up a new RAID, set up lvm and gluster, let it resync. Gluster health status shows no unsynced entries. Uppon going from maintenance to online from ovirt management It goes into non-operational status, vdsm log on the node shows: 2021-01-17 11:13:29,051+0100 INFO (jsonrpc/6) [api.host] START getAllVmStats() from=::1,48580 (api:48) 2021-01-17 11:13:29,051+0100 INFO (jsonrpc/6) [api.host] FINISH getAllVmStats return={'status': {'message': 'Done', 'code': 0}, 'statsList': (suppressed)} from=::1,48580 (api:54) 2021-01-17 11:13:29,052+0100 INFO (jsonrpc/6) [jsonrpc.JsonRpcServer] RPC call Host.getAllVmStats succeeded in 0.00 seconds (__init__:312) 2021-01-17 11:13:30,420+0100 WARN (monitor/4a62cdb) [storage.LVM] Reloading VGs failed (vgs=[u'4a62cdb4-b314-4c7f-804e-8e7275518a7f'] rc=5 out=[] err=[' Volume group "4a62cdb4-b314-4c7f-804e-8e7275518a7f" not found', ' Cannot process volume group 4a62cdb4-b314-4c7f-804e-8e7275518a7f']) (lvm:470) 2021-01-17 11:13:30,424+0100 ERROR (monitor/4a62cdb) [storage.Monitor] Setting up monitor for 4a62cdb4-b314-4c7f-804e-8e7275518a7f failed (monitor:330) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 327, in _setupLoop self._setupMonitor() File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 349, in _setupMonitor self._produceDomain() File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 159, in wrapper value = meth(self, *a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 367, in _produceDomain self.domain = sdCache.produce(self.sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 110, in produce domain.getRealDomain() File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 51, in getRealDomain return self._cache._realProduce(self._sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 134, in _realProduce domain = self._findDomain(sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 151, in _findDomain return findMethod(sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 176, in _findUnfetchedDomain raise se.StorageDomainDoesNotExist(sdUUID) I assume due to the changed LVM UUID it fails, right?

I can see the gluster mount (what ovirt mounts when it onlines a node) already, and gluster is happy too. Any help is appreciated! -Chris. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

About Translation
by Reyhan Gülçetin 18 Jan '21

18 Jan '21

Hello, I'm Reyhan! I am a third-grade physics engineering student in Turkey, I also worked as a part-time system administration in the university's IT Head Office until last month. (Now I'm more into DevOps). Back in there, I was responsible for understanding how we can apply oVirt to our IT Office, so I was scrolling through the documentations. I've decided to contribute, oVirt could be the project I used the most, since I'm not a bug-fixer, at least I can help with the translation. I'm a native Turkish speaker, so I thought it would go well. I wish you the best, Best regards. Reyhan Gülçetin.

how to install hosted-engine without internet connection ?
by tommy 18 Jan '21

18 Jan '21

Hi,every one! My env cannot access internet, but during the hosted-engine installation, It needs to run yum install to update system. I have made a yum source mirror local, but there is a step ( after create engine vm, the vm runs yum update using default repo configure ) it failed to connect yum source. How can I configure yum source to local yum server before the vm run update ? Thanks.

Disaster Recovery using Ansible roles
by Henry lol 17 Jan '21

17 Jan '21

Hi, I have 2 questions about Disaster Recovery with Ansible. 1) regarding Ansible failover, AFAIK, a mapping file must be generated before running failover. then, should I periodically generate a new mapping file to reflect the latest structure of the environment? 2) I guess Ansible failover uses OVF_STOREs to restore the environment and OVF_STOREs in storage domains are updated every 1 min as default. then, how to recover the changes made in the meantime?

Hyperconverged Ceph + Managed Block Storage
by Shantur Rathore 16 Jan '21

16 Jan '21

Hi all, I am planning my new oVirt cluster on Apple hosts. These hosts can only have one disk which I plan to partition and use for hyper converged setup. As this is my first oVirt cluster I need help in understanding a few bits. 1. Is Hyper converged setup possible with Ceph using cinderlib? 2. Can this hyper converged setup be on oVirt Node Next hosts or only Centos? 3. Can I install cinderlib on oVirt Node Next hosts? 4. Are there any pitfalls in such a setup? Thanks for your help Regards, Shantur

potential split-brain after upgrading Gluster version and rebooting one of three storage nodes
by user-5138＠yandex.com 15 Jan '21

15 Jan '21

Hello everyone, I'm running an oVirt cluster (4.3.10.4-1.el7) on a bunch of physical nodes with Centos 7.9.2009 and the Hosted Engine is running as a virtual machine on one of these nodes. As for the storage, I'm running GlusterFS 6.7 on three separate physical storage nodes (also Centos 7). Gluster itself has three different volumes of the type "Replicate" or "Distributed-Replicate". I recently updated both the system packages and the GlusterFS version to 6.10 on the first storage node (storage1) and now I'm seeing a potential split-brain situation for one of the three volumes when running "gluster volume heal info": Brick storage1:/data/glusterfs/nvme/brick1/brick Status: Connected Number of entries: 0 Brick storage2:/data/glusterfs/nvme/brick1/brick /c32d664d-69ba-4c3f-8ea1-240133963815/dom_md/ids / /.shard/.remove_me Status: Connected Number of entries: 3 Brick storage3:/data/glusterfs/nvme/brick1/brick /c32d664d-69ba-4c3f-8ea1-240133963815/dom_md/ids / /.shard/.remove_me Status: Connected Number of entries: 3 I checked the hashes and the "dom_md/ids" file has a different md5 on every node. Using the heal on the volume command doesn't do anything and the entries remain. The heal info for the other two volumes shows no entries. The affected gluster volume (type: replicate) is mounted as a Storage Domain using the path "storage1:/nvme" inside of oVirt and is used to store the root partitions of all virtual machines, which were running at the time of the upgrade and reboot of storage1. The volume has three bricks, with one brick being stored on each storage node. For the upgrade process I followed the steps shown at https://docs.gluster.org/en/latest/Upgrade-Guide/generic-upgrade-procedure/. I stopped and killed all gluster related services, upgraded both system and gluster packages and rebooted storage1. Is this a split brain situation and how can I solve this? I would be very grateful for any help. Please let me know if you require any additional information. Best regards

cockpit-ovirt-dashboard
by Gary Pedretty 15 Jan '21

15 Jan '21

So with the latest updates to Ovirt and CentOS 8 Stream it seems that you either can not install cockpit-ovirt-dashboard, or if you do, it downgrades cockpit-bridge and cockpit-system. You then end up not showing up to date on these hosts on Open Virtualization Manager and can only get back to a fully updated datacenter by doing a yum update --allowerasing which then removes cockpit-ovirt-dashboard. My main concern is now that the command line hosted-engine commands have been removed, if the hosted engine is not running for some reason you have no visibility into what is going on since the regular cockpit host interface will not show the virtualization features. You can't put a host in maintenance or start the engine manually. example.... [root@ravn-kvm-1 admin]# yum install cockpit-ovirt-dashboard //////snip/////// Installed products updated.

how does host's status changes ? Especially Unassigned or NonOperational or NonResponsible
by lifuqiong＠sunyainfo.com 15 Jan '21

15 Jan '21

Hi all, I'm confusing in Host's status in Ovirt Eninge. When will the host's status become Unassigned or NonOperational or NonResponsible? and If the host's status change to these statuses, What will ovirt response to it? After reading Ovirt Engine's source code, I find Only HostMonitoring.java and AutoRecoveryManager.java will change the status of Host. for example, If the host's status is changed to NonOperational, The AutoRecoveryManager will traverse the NonOperational hosts and calling ActivateVdsCommand.java, which will only set the Host's status to Unassigned ? But I don't know What's the next step? So where I can find the article or manual or other helpful information about this question? Thank you . Your sincerely Mark

Using Ansible ovirt_vm
by Matthew.Stier＠fujitsu.com 15 Jan '21

15 Jan '21

Over this weekend, I need to shutdown and restart 1500 VMs while I do work. Modifying an Ansible playbook I have, to accomplish that, seems easy enough. Last weekend I used the web gui and edited each Virtual Machine and changed the 'cluster' to the one I wanted to assign it too. Now I would like to automate this with Ansible. In between shutting them down and starting them up, I need to change the cluster registration of quite a few of the hosts, and I have concerns on how to do that. The Ansible ovirt_vm documentation on this is a bit fuzzy. I'm assuming it for assigning the cluster, but in some examples it appears to be used as a filter. Which changes the meaning. Is it "start the VM in this cluster" or "start this VM if it is in this cluster". The playbook I'm working from is straight forward and has three tasks. First, an ovirt_auth task to log into the SHE. Second, an ovirt_vm task which loops though the group of virtualmachines, defined in an 'ini' file. Third, an ovirt_auth task to logout from the SHE. For stopping, I assume I specify a name, and state to 'stopped' and that should initiate the shutdown. For starting, I assume I should set the state to 'running'. For changing the cluster a vm is assigned to, do I simply need to use the 'cluster' parameter with a value of new cluster? Are there other actions that need to be taken? The VM need to be un and re-registered for the change to take effect? I'd like to make the cluster change individual playbook, but could it be added to the start or stop playbook. (ie: stop and change cluster, start on new cluster) Waiting for the wisdom of the community.

Networking question on setting up self-hosting engine

Dear Ovirt list, I saw some failures in /var/log/ovirt-hosted-engine-setup such as: 1) Install oVirt Engine packages for restoring backup 2) Copy engine logs etc But I'm not sure what is the root cause for the setup to fail?

[ANN] oVirt 4.4.5 First Release Candidate is now available for testing
by Lev Veyde 14 Jan '21

14 Jan '21

oVirt 4.4.5 First Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 First Release Candidate for testing, as of January 14th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. 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>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Q: oVirt 4.4.4.7 Node settings on CentOS Stream
by Andrei Verovski 14 Jan '21

14 Jan '21

Hi ! I’m installing new oVirt 4.4.4 node on CentOS Stream and its seems there are some changes since older node on CentOS 7.x. 1) NFS shares for storage domain. In 7.x I used chown -Rv nfsnobody:nfsnobody /vmraid/nfs; chmod -Rv 755 /vmraid/nfs In Stream nfsnobody don’t exists, should I use: chown -Rv nobody:nobody /vmraid/nfs; chmod -Rv 777 /vmraid/nfs Is that correct settings? 2) SELinux seems to be more permissive now, looks like I don’t have to tweak it to have my custom cron and SNMP scripts running. Yes, SELinux is running, getenforce -> yields “Enforcing”. Will oVirt sw node installation change this behaviour? Thanks in advance Andrei
