Hosted engine VM not coming up after Storage rebuild.
by Sumit Basu 06 Oct '23

06 Oct '23

Hi, We are running Ovirt 4.3 on IBM x3650, x3550 servers with our SAN on IBM Midrange storage DS5300. All the storage domains are separate LUN's in the storage with a dedicated LUN for the HostedEngine VM. The storage had a failure due to a major power issue. One of the storage array's that have the storage domains had to be re-constructed using IBM's StorageManager tool. After booting the hosts, i can see all the storage domains as LUN's with the multipath -ll from all the hosts, but on starting the hosted engine with #hosted-engine --vm-start, and checking with --vm-status i get "Engine status : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"}'. The global maintenance mode is enabled and i tried "hosted-engine --console" - after logging in i checked the boot.log, i find [FAILED] Failed to mount /var/log. See 'systemctl status var-log.mount' for details. [DEPEND] Dependency failed for Update UTMP about System Boot/Shutdown. [DEPEND] Dependency failed for Update UTMP about System Runlevel Changes.

keycloak Active Directory BufferOverFlowException
by karl.morgan＠gmail.com 05 Oct '23

05 Oct '23

been trying to get a configuration working with ovirt 4.5.4 and keycloak and windows Active Directory I have had partial success in that i can with a little fiddling use ldap authentication for users. The fiddling involves going in and adding specific permissions to each ID after the first attempt has been made. I am now trying to get groups working such that I can have an AD user group automatically determine a users capabilities dependent on inclusion in specific groups. I have keycloak configured where, from within keycloak I can list users, And i can see which groups a user is a member of. It looks like is should be working. However, in Ovirt im getting invalid data error in the web and logs print the following ==> error_log <== [Thu Oct 05 09:22:58.037130 2023] [proxy_ajp:error] [pid 75583:tid 140622648301312] AH03229: ajp_msg_append_cvt_string(): BufferOverflowException 4 5694 ==> ssl_error_log <== [Thu Oct 05 09:22:58.037162 2023] [proxy_ajp:error] [pid 75583:tid 140622648301312] [client 172.28.96.180:43980] AH00971: ajp_marshal_into_msgb: Error appending the header value, referer: https://ov2ctl01-mn.internal.shutterfly.com/ovirt-engine/ [Thu Oct 05 09:22:58.037171 2023] [proxy_ajp:error] [pid 75583:tid 140622648301312] [client 172.28.96.180:43980] AH00988: ajp_send_header: ajp_marshal_into_msgb failed, referer: https://ov2ctl01-mn.internal.shutterfly.com/ovirt-engine/ [Thu Oct 05 09:22:58.037176 2023] [proxy_ajp:error] [pid 75583:tid 140622648301312] (120001)APR does not understand this error code: [client 172.28.96.180:43980] AH00868: request failed to 127.0.0.1:8702 (127.0.0.1), referer: https://ov2ctl01-mn.internal.shutterfly.com/ovirt-engine/ Pretty sure i need to be able to adjust a buffer size between keycloak and ajp module but am clueless how to proceed. Any help would be appreciated

How to obtain vm snapshots status
by anton.alymov＠cyberprotect.ru 04 Oct '23

04 Oct '23

Hi! I use ovirt rest api to start vm, backup vm and then remove vm. I start vm, wait for vmstatus up, then start backup, wait for starting, finalize, wait for succeeded, wait for disk unlock. Looks like backup is finished here from my side.Because ovirt repost succeed status and unlocks disk. But if i try shutdown and remove vm ovirt will throw error Cannot remove VM. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again. Ok, ovirt is right here, I see from web interface that operation hasn't finished yet. How can I obtain correct status where vm can be removed? I also tried to get info about vm snapshots but all of them had Status: ok

Cannot remove template because a disk is based on it
by nicolas＠devels.es 04 Oct '23

04 Oct '23

Hi, We're running oVirt 4.5. We have a template which we'd like to get rid of, there are no VMs based on it. However, trying to remove it oVirt states that: Cannot remove Template. The following Disk(s) are based on it: (b54ee1cb-ed64-4db4-bd3d-eac8b22ea095) . When opening the 'Disks' subtab in the template, it appears a disk (screenshot attached). However, when opening the oVirt Storage->Disks option, I cannot find the disk by the ID, not even ordering the ID column and trying to find it visually. Can anyone point to the problem and a possible solution/workaround? Thanks.

What certs need monitoring for expiration for Ovirt hosts ?
by morgan cox 03 Oct '23

03 Oct '23

Hi. I am aware of the following certs - "/etc/pki/vdsm/certs/vdsmcert.pem" - "/etc/pki/vdsm/libvirt-spice/server-cert.pem" - "/etc/pki/vdsm/libvirt-vnc/server-cert.pem" - "/etc/pki/libvirt/clientcert.pem" - "/etc/pki/vdsm/libvirt-migrate/server-cert.pem" And are monitoring them to avoid certs being expired. We have a 3rd party cert/ca - do I also need to monitor the following - "/etc/pki/ovirt-vmconsole/ca.pub" - "/etc/pki/vdsm/certs/cacert.pem" - "/etc/pki/vdsm/libvirt-migrate/ca-cert.pem" - "/etc/pki/vdsm/libvirt-spice/ca-cert.pem" - "/etc/pki/vdsm/libvirt-vnc/ca-cert.pem" - "/etc/pki/CA/cacert.pem" If the CA is updated on the engine do the above ca certs get updated with an update or re-enroll ? Thanks

Unable to add KVM (ubuntu flavour)hypervisors on Ovirt engine.
by spp16121991＠gmail.com 26 Sep '23

26 Sep '23

Hi all, I am a noob in KVM. I am a VMware engineer. I have created a lab environment to where i have hosted KVM as nested hypervisors within esxi. I have a vsan environment. I want to create a similar KVM environment. hence, i have deployed 3 kvm hypervisors (nested) i have deployed Ovirt-manager ( equivalent to vcenter) to host/manage my KVM hypervisors. to deploy Ovirt-manager, i installed ovirt packages in centos VM. Because ovirt pacjages are not available in ubuntu, hence choose centos. next is i want to add kvm hypervisors on ovirt manager similar to how we add esxi hosts to vcenter. That is where i am failing. From my limited understanding in KVM, ovirt is looking for yum package manager , KVM are ubuntu flavoured, hence it has apt package manager. What my ask is, can this be fixed? is there a file i need to edit in ovirt-engine.? Can Ovirt-manager host KVM of ubuntu flavour? Please advise. Checked the ovirt logs: Here is the log excerpts: ---------------------------------------------- } ], "python3-oauthlib" : [ { "name" : "python3-oauthlib", "version" : "3.1.0-1ubuntu2", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-openssl" : [ { "name" : "python3-openssl", "version" : "19.0.0-1build1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pexpect" : [ { "name" : "python3-pexpect", "version" : "4.6.0-1build1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pkg-resources" : [ { "name" : "python3-pkg-resources", "version" : "45.2.0-1ubuntu0.1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-problem-report" : [ { "name" : "python3-problem-report", "version" : "2.20.11-0ubuntu27.27", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-ptyprocess" : [ { "name" : "python3-ptyprocess", "version" : "0.6.0-1ubuntu1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pyasn1" : [ { "name" : "python3-pyasn1", "version" : "0.4.2-3build1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pyasn1-modules" : [ { "name" : "python3-pyasn1-modules", "version" : "0.2.1-0.2build1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pymacaroons" : [ { "name" : "python3-pymacaroons", "version" : "0.13.0-3", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-pyrsistent" : [ { "name" : "python3-pyrsistent", "version" : "0.15.5-1build1", "arch" : "amd64", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-requests" : [ { "name" : "python3-requests", "version" : "2.22.0-2ubuntu1.1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-requests-unixsocket" : [ { "name" : "python3-requests-unixsocket", "version" : "0.2.0-2", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-secretstorage" : [ { "name" : "python3-secretstorage", "version" : "2.3.1-2ubuntu1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-serial" : [ { "name" : "python3-serial", "version" : "3.4-5.1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-service-identity" : [ { "name" : "python3-service-identity", "version" : "18.1.0-5build1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-setuptools" : [ { "name" : "python3-setuptools", "version" : "45.2.0-1ubuntu0.1", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-simplejson" : [ { "name" : "python3-simplejson", "version" : "3.16.0-2ubuntu2", "arch" : "amd64", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-six" : [ { "name" : "python3-six", "version" : "1.14.0-2", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-software-properties" : [ { "name" : "python3-software-properties", "version" : "0.99.9.12", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-systemd" : [ { "name" : "python3-systemd", "version" : "234-3build2", "arch" : "amd64", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-twisted" : [ { "name" : "python3-twisted", "version" : "18.9.0-11ubuntu0.20.04.2", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-twisted-bin" : [ { "name" : "python3-twisted-bin", "version" : "18.9.0-11ubuntu0.20.04.2", "arch" : "amd64", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], "python3-update-manager" : [ { "name" : "python3-update-manager", "version" : "1:20.04.10.11", "arch" : "all", "category" : "python", "origin" : "Ubuntu", "source" : "apt" } ], ============================== "duration" : 2.05353, "event_loop" : null, "uuid" : "f72c96ea-2491-4612-807e-37da9d563d4d" } } } 2023-09-15 03:18:41 EDT -
