I had noticed some times that importing the cert form GUI had not resolved the issue. You may try to manually get the CA cert from engine (/etc/pki/ovirt-engine/ca.pem) and import it at your browser. Clean cache at browser and try again. The browser should indicate the connection is trusted and secure.

Hi, We are planning to upgrade our cluster hardware. We would like to know if Intel Cascade Lake CPUs are supported on ovirt 4.4.3. Any recommendation is very welcome. Regards, Ramon

oVirt Engine LDAP aaa - rfc2307bis issues
by Jake R 23 Nov '20

23 Nov '20

Hi, I have LDAP with rfc2307bis schema - I have posixGroup, with members defined as FDNs under the member attribute. Currently, if I login to oVirt via the AAA extension. then my groups are not enumerated. The LDAP searches (recorded on the LDAP server) are: slapd[1503]: conn=7876 op=2 SRCH base="dc=example,dc=com" scope=2 deref=0 filter="(&(objectClass=posixGroup)(memberUid=jreynolds))" slapd[1503]: conn=7876 op=2 SRCH attr=entryUUID cn description slapd[1503]: conn=7871 op=2 SRCH base="dc=example,dc=com" scope=2 deref=0 filter="(&(|(objectClass=groupOfUniqueNames)(objectClass=posixGroup))(uniqueMember:uniqueMemberMatch:=cn=jreynolds,ou=users,dc=example,dc=com))" slapd[1503]: conn=7871 op=2 SRCH attr=entryUUID cn description This returns no results, as the search needs to search for 'member' attribute, with an FDN. The issue looks to be inherited from the simple.properties file (regardless of if I use rfc2307, rfc2307-openldap profile), with the line: search.simple-resolve-groups-member.search-request.filter = &${seq:simple_filterGroupObject}(${seq:simple_attrGroupMemberDN}=${seq:_simple_dn_encoded}) I can fix the issue by replacing "${seq:simple_attrGroupMemberDN}=" with "member=", but this feels pretty hacky. I cannot find where this variable is defined, nor how to change it. Is the correct way to do this to create a new profile that overwrites the filter value? Or am I doing something wrong? I don't think my LDAP schema is particularly unusual, as far as I'm aware it complies with rfc2307bis spec. Thanks, Jake

Can't find storage server connection
by francesco＠shellrent.com 23 Nov '20

23 Nov '20

Hi all, I'm using oVirt SDK python for retrieving info about storage domain, in several hosts (centos7/ovirt4.3 and centos8/ovirt4.4), but the script exits with the following error in some of them: Traceback (most recent call last): File "get_uuid.py", line 70, in <module> storage_domain = sds_service.list(search='name=data-foo')[0] File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/services.py", line 26296, in list return self._internal_get(headers, query, wait) File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/service.py", line 211, in _internal_get return future.wait() if wait else future File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/service.py", line 55, in wait return self._code(response) File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/service.py", line 208, in callback self._check_fault(response) File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/service.py", line 132, in _check_fault self._raise_error(response, body) File "/root/.local/lib/python2.7/site-packages/ovirtsdk4/service.py", line 118, in _raise_error raise error ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "Can't find storage server connection for id '92444a95-0be7-4589-ac46-1ed6dfe7ed4c'.". HTTP response code is 500. The portion of the script that search for the storage domain is the following: sds_service = connection.system_service().storage_domains_service() storage_domain = sds_service.list(search='name={}'.format(storage_domain_name))[0] Now: I have no real clue on which ID "92444a95-0be7-4589-ac46-1ed6dfe7ed4c'" but digging in the engine logs it refers to StorageServerConnections ID: [root@ovirt-engine ovirt-engine]# zgrep 92444a95-0be7-4589-ac46-1ed6dfe7ed4c *.gz engine.log-20201108.gz:2020-11-07 06:05:54,352+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ConnectStorageServerVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-79) [3ffb810c] START, ConnectStorageServerVDSCommand(HostName = another-server.foo.com, StorageServerConnectionManagementVDSParameters:{hostId='7d202bc7-002b-4426-8446-99b6b346874e', storagePoolId='82d0b3de-0334-451c-8321-c3533de9a894', storageType='LOCALFS', connectionList='[StorageServerConnections:{id='92444a95-0be7-4589-ac46-1ed6dfe7ed4c', connection='/data', iqn='null', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}]', sendNetworkEventOnFailure='true'}), log id: 1509fe17 As I said, I tried to execute the script from several hosts: some of them with oVirt 4.3 and other with oVirt 4.4 but it can run, or not, on both of versions. When I try to manage the storage domain via ovirt-engine GUI on the hosts that the script exit with the mentioned error, I recieve the following error: Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'a' of null Please have your administrator check the UI logs Any slightest idea on what is going on? Thank you for your time and help, Francesco

Best and clean way to have oVirt qemu and libvirt versions on CentOS 8
by Gianluca Cecchi 22 Nov '20

22 Nov '20

Hello, normally with current CentOS 8.2 I get qemu-kvm-core-15:2.12.0-99.module_el8.2.0+524+f765f7e0.4.x86_64 libvirt-daemon-4.5.0-42.module_el8.2.0+320+13f867d7.x86_64 With oVirt 4.4 having qemu-kvm-core-4.2.0-29.el8.3.x86_64 libvirt-daemon-6.0.0-25.2.el8.x86_64 and in current Fedora 32 updates: qemu-kvm-core-4.2.1-1.fc32.x86_64.rpm libvirt-daemon-6.1.0-4.fc32.x86_64.rpm I see on CentOS these groups somehow related to Virtualization: Virtualization Host Virtualization Client Virtualization Hypervisor Virtualization Platform Virtualization Tools What could be the best and less intrusive repo to enable on plain CentOS 8.2 to get qemu-kvm and libvirt versions quite similar to oVirt shipped ones, or fedora ones, without enabling all the ovirt 4.4 repos? Thanks, Gianluca

ovirt-imageio-proxy not working after updating SSL certificates with a wildcard cert issued by AlphaSSL (intermediate)
by Lynn Dixon 22 Nov '20

22 Nov '20

All, I recently bought a wildcard certificate for my lab domain (shadowman.dev) and I replaced all the certs on my RHV4.3 machine per our documentation. The WebUI presents the certs successfully and without any issues, and everything seemed to be fine, until I tried to upload a disk image (or an ISO) to my storage domain. I get this error in the events tab: https://share.getcloudapp.com/p9uPvegx [image: image.png] I also see that the disk is showing up in my storage domain, but its showing "Paused by System" and I can't do anything with it. I cant even delete it! I have tried following this document to fix the issue, but it didn't work: https://access.redhat.com/solutions/4148361 I am seeing this error pop into my engine.log: https://pastebin.com/kDLSEq1A And I see this error in my image-proxy.log: WARNING 2020-07-24 15:26:34,802 web:137:web:(log_error) ERROR [172.17.0.30] PUT /tickets/ [403] Error verifying signed ticket: Invalid ovirt ticket (data='------my_ticket_data-----', reason=Untrusted certificate) [request=0.002946/1] Now, when I bought my wildcard, I was given a root certificate for the CA, as well as a separate intermediate CA certificate from the provider. Likewise, they gave me a certificate and a private key of course. The root and intermediate CA's certificates have been added to /etc/pki/ca-trust/source/anchors/ and I did an update-ca-trust. I also started experiencing issues with the ovpn network provider at the same time I replaced the SSL certs, but I disregarded it at the time, but now I am thinking its related. Any advice on what to look for to fix the ovirt-imageio-proxy?

Re: Fix corrupt self-hosted engine
by Alex K 22 Nov '20

22 Nov '20

For the records, After having fixed the major fs issues with guestfish and since the DB was not starting up, I removed everything from DB data dir and recreated it as below: rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/* /opt/rh/rh-postgresql10/root/usr/bin/postgresql-setup --initdb systemctl restart rh-postgresql10-postgresql.service Then proceeded with the restoration, where I requested to provision all missing databases: engine-backup --mode=restore --file=engine-backup.gz --provision-all-databases \ --log=restore.log --restore-permissions Following this, ran engine-setup, as instructed from the restore operation. Gained engine web access and saw the same running VMs were shown as up without issues. I only observed one VM not able to start due to illegal volume, but that's another story.
