Gluster Hyperconverged fails with single disk partitioned
by Shantur Rathore 21 Jan '21

21 Jan '21

Hi, I am trying to setup a single host Self-Hosted hyperconverged setup with GlusterFS. I have a custom partitioning where I provide 100G for oVirt and its partitions and rest 800G to a physical partition (/dev/sda4). When I try to create gluster deployment with the wizard, it fails TASK [gluster.infra/roles/backend_setup : Create volume groups] **************** failed: [ovirt-macpro-16.lab.ced.bskyb.com] (item={'key': 'gluster_vg_sda4', 'value': [{'vgname': 'gluster_vg_sda4', 'pvname': '/dev/sda4'}]}) => {"ansible_loop_var": "item", "changed": false, "err": " Device /dev/sda4 excluded by a filter.\n", "item": {"key": "gluster_vg_sda4", "value": [{"pvname": "/dev/sda4", "vgname": "gluster_vg_sda4"}]}, "msg": "Creating physical volume '/dev/sda4' failed", "rc": 5} I checked and /etc/lvm/lvm.conf filter doesn't allow /dev/sda4. It only allows PV for onn VG. Once I manually allow /dev/sda4 to lvm filter, it works fine and gluster deployment completes.

Is there anyway to provide tell gluster deployment to add it to lvm config. Thanks, Shantur

Hello, I have a Dell VRTX with 2 M640 servers, we installed oVirt version 4.3.10.4-1.el7, we have 1 cluster, 2 hosts and 2 storage domains. I need to change ALL the network environment solution, that is, from IP's 192.168.11.XX to 172.16.10.XX. Can anybody help me? Thank you. Román Larumbe S. Facebook: Serahp LS

VMware Fence Agent
by Robert Tongue 21 Jan '21

21 Jan '21

Greetings all, I am new to oVirt, and have a proof of concept setup with a 3-node oVirt cluster nested inside of VMware VCenter to learn it, so then I can efficiently migrate that back out to the physical nodes to replace VCenter. I have gotten all the way to a working cluster setup, with the exception of fencing. I used engine-config to pull in the vmware_soap fence agent, and enabled all the options, however there is one small thing I cannot figure out. The connection uses a self-signed certificate on the vcenter side, and I cannot figure out the proper combination of engine-config -s commands to get the script to be called with the "ssl-insecure" option, which does contain a value. It just needs the option passed. Is there anyone out there in the ether that can help me out? I can provide any information you request. Thanks in advance. The fence agent script is called with the following syntax in my tests, and returned the proper status: [root@cluster2-vm ~]# /usr/sbin/fence_vmware_soap -o status -a vcenter.address --username="administrator(a)vsphere.local" --password="0bfusc@t3d" --ssl-insecure -n cluster1-vm Status: ON -phunyguy

Mutually exclusive VMs
by Shantur Rathore 21 Jan '21

21 Jan '21

Hi all, I am trying to figure if there is a way to force oVirt to schedule VMs on different hosts. So if I am cloning 6 VMs from a template, I want oVirt to schedule them on all different hosts. No 2 VMs must schedule on the same host. I know that there is pin-to-host functionality but I don't want to manually pin it to hosts. Thanks Shantur

Unable to edit DNS connfiguration on hosts
by miguel.garcia＠toshibagcs.com 20 Jan '21

I had to replace the DNS server in my network so I want to update the DNS address on each host so in oVirt web interface I go to Compute > Host > Hostname > Network Interfaces > Setup Host Networks Right there I click on the edit button of the vlan for networking, check out (host ip address is static), DNS configuration, check DNS configuration, Type DNS ip address and click ok to save change. I got message: Error while executing action HostSetupNetworks: Unexpected Exception. Into engile.log found message "Operation not permitted" related to this action despite that was executed with my user account (wint admin privileges) and same message was returned using admin@internal user. 2021-01-20 11:35:31,579-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] START, HostSetupNetworksVDSCommand(HostName = hyp10.eboss, HostSetupNetworksVdsCommandParameters:{hostId='39c05625-7b59-4a38-a5a9-5d556ae1fe18', vds='Host[hyp10.eboss,39c05625-7b59-4a38-a5a9-5d556ae1fe18]', rollbackOnFailure='true', commitOnSuccess='true', connectivityTimeout='120', networks='[HostNetwork:{defaultRoute='true', bonding='false', networkName='tgcs182vlan', vdsmName='tgcs182vlan', nicName='eno1', vlan='null', vmNetwork='true', stp='false', properties='[]', ipv4BootProtocol='STATIC_IP', ipv4Address='10.89.182.10', ipv4Netmask='255.255.255.0', ipv4Gateway='10.89.182.1', ipv6BootProtocol='AUTOCONF', ipv6Address='null', ipv6Prefix='null', ipv6Gateway='null', nameServers='[NameServer:{address='10.89.182.204'}, NameServer:{address='10.89.176.71'}]'}]', removedNetworks='[]', bonds='[]', removedBonds='[]', clusterSw itchType='OVS', managementNetworkChanged='false'}), log id: 23059843 2021-01-20 11:35:31,582-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] FINISH, HostSetupNetworksVDSCommand, return: , log id: 23059843 2021-01-20 11:35:35,665-05 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Unexpected return value: Status [code=-32603, message=Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}] 2021-01-20 11:35:35,665-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Failed in 'HostSetupNetworksVDS' method 2021-01-20 11:35:35,666-05 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Unexpected return value: Status [code=-32603, message=Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}] 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM hyp10.eboss command HostSetupNetworksVDS failed: Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'} 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Error: VDSGenericException: VDSErrorException: Failed to HostSetupNetworksVDS, error = Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}, code = -32603 2021-01-20 11:35:35,673-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.HostSetupNetworksVDSCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Command 'HostSetupNetworksVDSCommand(HostName = hyp10.eboss, HostSetupNetworksVdsCommandParameters:{hostId='39c05625-7b59-4a38-a5a9-5d556ae1fe18', vds='Host[hyp10.eboss,39c05625-7b59-4a38-a5a9-5d556ae1fe18]', rollbackOnFailure='true', commitOnSuccess='true', connectivityTimeout='120', networks='[HostNetwork:{defaultRoute='true', bonding='false', networkName='tgcs182vlan', vdsmName='tgcs182vlan', nicName='eno1', vlan='null', vmNetwork='true', stp='false', properties='[]', ipv4BootProtocol='STATIC_IP', ipv4Address='10.89.182.10', ipv4Netmask='255.255.255.0', ipv4Gateway='10.89.182.1', ipv6BootProtocol='AUTOCONF', ipv6Address='null', ipv6Prefix='null', ipv6Gateway='null', nameServers='[NameServer:{address='10.89.182.204'}, NameServer:{address='10.89.176.71'}]'}]', removedNetworks='[]', bonds='[]', removedBonds='[]', cluster SwitchType='OVS', managementNetworkChanged='false'})' execution failed: VDSGenericException: VDSErrorException: Failed to HostSetupNetworksVDS, error = Internal JSON-RPC error: {'reason': '[Errno 1] Operation not permitted'}, code = -32603 2021-01-20 11:35:35,673-05 INFO [org.ovirt.engine.core.bll.network.host.HostSetupNetworksCommand] (default task-482931) [b9a19834-3f15-42da-af2c-55e292dfedea] Host setup networks finished.

Problems Installing host on brand new 4.4 cluster
by David Johnson 20 Jan '21

20 Jan '21

Hi all, I am standing up a brand new cluster on new hardware. The ovirt controller is installed and appears to be running fine. When I attempt to add the new host, I get the flag that says "Non Operational", and the exclamation mark with the message "Host has no default route". I have confirmed that I have bidirectional ssh connections between the controller and the new host. Selinux is disabled. Firewall is disabled. I can get to the host console via the link in the GUI Compute|Hosts page. This looks like a common symptom of a host of problems, but there is nothing to readily indicate what the actual problem is. In the ovirt-engine log, I found this entry: "Host 'ovirt-host-03' is set to Non-Operational, it is missing the following networks: 'ovirtmgmt'" This seems self-explanatory, but I see no way to add the missing network to the host. Thank you in advance for your help Regards, David Johnson * <http://www.linkedin.com/in/pojoguy>*

Install of RHV 4.4 failing - "Host is not up, please check logs, perhaps also on the engine machine"
by james.freeman＠a24.io 19 Jan '21

19 Jan '21

Hi all I am in the process of migrating a RHV 4.3 setup to RHV 4.4 and struggling with the setup. I am installing on RHEL 8.3, using settings backed up from the RHV 4.3 install (via 'hosted-engine --deploy --restore-from-file=backup.bck'). The install process always fails at the same point for me at the moment, and I can't figure out how to get past it. As far as install progress goes, the local hosted-engine comes up and runs on the node. I have been able to grep for local_vm_ip in the logs, and can SSH into it with the password I set during the setup phase. However the install playbooks always fail with: 2021-01-18 18:38:00,086-0500 ERROR otopi.plugins.gr_he_common.core.misc misc._terminate:167 Hosted Engine deployment failed: please check the logs for the issue, fix accordingly or re-deploy from scratch. Earlier in the logs, I note the following: 2021-01-18 18:34:51,258-0500 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"} 2021-01-18 18:37:16,661-0500 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 fatal: [localhost]: FAILED! => {"changed": false, "msg": "The system may not be provisioned according to the playbook results: please check the logs for the issue, fix accordingly or re-deploy from scratch.\n"} Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-ansiblesetup/core/misc.py", line 435, in _closeup raise RuntimeError(_('Failed executing ansible-playbook')) RuntimeError: Failed executing ansible-playbook 2021-01-18 18:37:18,996-0500 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Closing up': Failed executing ansible-playbook 2021-01-18 18:37:32,421-0500 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 fatal: [localhost]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ssh: connect to host rhvm.example.org port 22: No route to host", "skip_reason": "Host localhost is unreachable", "unreachable": true} I find the unreachable message a bit odd, as at this stage all that has happened is that the local hosted-engine has been brought up to be configured, and so it is running on virbr0, not on my actual network. As a result, that DNS address will never resolve, and the IP it resolves to won't be up. I gave the installation script permission to modify the local /etc/hosts but this hasn't improved things. I presume I'm missing something in the install process, or earlier on in the logs, but I've been scanning for errors and possible clues to no avail. Any and all help greatly appreciated!

VM Disks order
by Erez Zarum 19 Jan '21

19 Jan '21

When attaching a disk it is not possible to set the disk order nor modify the order later. Example: A new VM is provisioned with 5 disks, Disk0 is the OS and then later attached disks by order up to Disk4. Removing Disk3 and then later attaching does not promise it will be attached back as Disk3. In most other platforms it is possible to set the order. Am i missing something? if not, is there a plan to add this feature?

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.

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? Can I someone fix/change the UUID and get the node back up again? It does not seem to be a major issue, to be honest. 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.

This time I setup a bridge BR0 and disable EM1 (the first Ethernet interface on the host), and then created Bond0 on-top of BR0. Both Bond0 and EM2 (the second Ethernet interface on the host) were up. And then I tried again using Ovirt-Cockpit wizard, with the Engine VM set on BR0, and the deployment of Engine VM simply failed. The Engine and Host are using the same network numbers (192.168.2.0/24) and they resolved correctly.

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
