ldap auth problem after upgrade from 4.4.1 to 4.4.2

07 Oct '20

Hi, I just upgraded my HE to 4.4.2 but now I cannot login using my ldap aaa profile anymore. We are using Novell/NetIQ E-directory (load ballanced by haproxy, probably not important...) In 4.4.1 I was hit by removed TLSv1 (which is the newest protocol supported by our edir) from default crypto policies but I was able revert it by update-crypto-policies --set LEGACY after upgrade to 4.4.2 the error is server_error: An error occurred while attempting to connect to server ldap1.slu.cz:389: IOException(LDAPException(resultCode=91 (connect error), errorMessage='An error occurred while attempting to establish a connection to server ldap1.slu.cz/193.84.206.212:389: SocketException(Network is unreachable (connect failed)), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb')) but our ldap server is reachable from ovirt, I tested it via (also ldaps and startls variants are working) ldapsearch -H ldap://ldap1.slu.cz -x -D cn=*****,ou=******,o=su -w '************' -b 'o=su' As a workaround I tried to set plain ldap protocol in profile cat /etc/ovirt-engine/aaa/CRO.properties include = <rfc2307-edir.properties> vars.server = ldap1.slu.cz vars.port = 389 vars.user = cn=*****,ou=******,o=su vars.password = ************** pool.default.serverset.single.server = ${global:vars.server} pool.default.serverset.single.port = ${global:vars.port} pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} pool.default.ssl.startTLS = false pool.default.ssl.enable = false #pool.default.ssl.protocol = TLSv1 #pool.default.ssl.startTLSProtocol = TLSv1 #pool.default.ssl.insecure = true sequence-init.init.100-my-edir-init-vars = my-edir-init-vars sequence.my-edir-init-vars.010.description = set baseDN sequence.my-edir-init-vars.010.type = var-set sequence.my-edir-init-vars.010.var-set.variable = simple_baseDN sequence.my-edir-init-vars.010.var-set.value = o=su #search.default.search-request.derefPolicy = ALWAYS but the error is the same... ovirt-engine-extensions-tool aaa login-user --profile=CRO --user-name=my_user ....

engine-setup in 4.4.2 not using yum/dnf proxy?
by Gianluca Cecchi 07 Oct '20

07 Oct '20

Hello, I'm testing upgrade from 4.3.10 to 4.4.2 for a standalone manager with local database environment. I configured the new engine system as a CentOS 8.2 with a proxy in /etc/yum.conf (that is a link to /etc/dnf/dnf.com) and that worked for all the steps until engine-setup. Now I get this [root@ovmgr1 ~]# engine-setup [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup Configuration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf, /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20201006112458-p84x9i.log Version: otopi-1.9.2 (otopi-1.9.2-1.el8) [ INFO ] DNF Downloading 1 files, 0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloading CentOS-8 - AppStream 0.00/0.00KB [ INFO ] DNF Downloaded CentOS-8 - AppStream [ INFO ] DNF Errors during downloading metadata for repository 'AppStream': ....

Do I have to put proxy info into any other file? Thanks, Gianluca

Upgrade oVirt from 4.3.10 to 4.4.2 and AD users
by Gianluca Cecchi 06 Oct '20

06 Oct '20

Hello, I'm upgrading a standalone engine with local database and with 3 hosts from oVirt 4.3.10 to 4.4.2 and I'm cross checking both oVirt and RHV documents. In my oVirt environment I have integration with AD for web admin access. Inside RHV upgrade guide docs there is this statement regarding manager upgrade: " Install optional extension packages if they were installed on the Red Hat Virtualization Manager 4.3 machine. # yum install ovirt-engine-extension-aaa-ldap ovirt-engine-extension-aaa-misc ovirt-engine-extension-logger-log4j NOTE The configuration for these package extensions must be manually reapplied because they are not migrated as part of the backup and restore process. " In my case I had ovirt-engine-extension-aaa-ldap and ovirt-engine-extension-aaa-misc installed on 4.3.10. So after "engine-backup --mode=restore ...." command I executed: [root@ovmgr1 ~]# yum install ovirt-engine-extension-aaa-ldap ovirt-engine-extension-aaa-misc Last metadata expiration check: 0:01:11 ago on Tue 06 Oct 2020 11:23:04 AM CEST. Dependencies resolved. ========================================================================================== Package Arch Version Repository Size ========================================================================================== Installing: ovirt-engine-extension-aaa-ldap noarch 1.4.1-1.el8 ovirt-4.4 127 k ovirt-engine-extension-aaa-misc noarch 1.1.0-1.el8 ovirt-4.4 37 k Installing dependencies: unboundid-ldapsdk noarch 4.0.14-2.el8 ovirt-4.4-centos-ovirt44 4.0 M Transaction Summary ========================================================================================== Install 3 Packages Total download size: 4.2 M Installed size: 4.5 M and followed the next upgrade flow steps. After finishing the engine upgrade with the "engine-setup" step, it seems actually that I can still connect to my engine with my AD accounts, so that I don't have to do any manual step described... Does it match any one other experience? Gianluca

oVirt Node 4.4.2 is now generally available
by Sandro Bonazzola 06 Oct '20

06 Oct '20

oVirt Node 4.4.2 is now generally available The oVirt project is pleased to announce the general availability of oVirt Node 4.4.2 , as of September 25th, 2020. This release completes the oVirt 4.4.2 release published on September 17th 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… ) How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 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 4.4.2 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 4.4.2 (redeploy in case of already being on 4.4.2). 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>. What’s new in oVirt Node 4.4.2 Release? oVirt Node has been updated, including: - oVirt 4.4.2: http://www.ovirt.org/release/4.4.2/ - Ansible 2.9.13: https://github.com/ansible/ansible/blob/stable-2.9/changelogs/CHANGELOG-v2.… - Glusterfs 7.7: https://docs.gluster.org/en/latest/release-notes/7.7/ - Advanced Virtualization 8.2.1 See the release notes [1] for installation instructions and a list of new features and bugs fixed.

This is a possible solution we considered, but it is not implemented yet. The next line is: Since creating special paused VM for backing up non-running VM is a lot of work, we may defer support for backing up non-running VMs. We got a request to implement this from other backup vendor, and we are discussing the possible solutions with platform folks.

Upgrade Host Compatibility Version
by jb 05 Oct '20

05 Oct '20

Hello everybody, for some days I upgrade our environment from ovirt 4.3 to 4.4.2 and now I stuck on upgrading the host compatibility version. It show there a compatibility until version 4.4. The VMs have a limit until version 4.5 and the cluster shows to that I can upgrade them until 4.5. On the cluster page is also a Upgrade guide, but this fails when I try that one. At the moment I have only one host to upgrade (no hosted engine)... Thanks for helping! Jonathan
