I get PEM.code from default smb file from domain controller 3. when i try the following command to check user "ovirt-engine-extensions-tool aaa login-user --profile=eipl.com --user-name=administrator" it show me the following error "SEVERE Cannot resolve principal 'administrator(a)eipl.com'" so please give me any idea about this

Single Node oVirt and Gluster Hyperconverged
by Jeremy Tourville 15 Nov '18

15 Nov '18

I have a question about this specific prerequisite- * You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out. Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other. To segregate the backend network, the gluster cluster is formed using the backend network addresses, and the nodes are added to the engine using the frontend network address. >>>You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out.>>>This part is very clear to me. You need at least 2 NICs. >>>Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other. To segregate the backend network, the gluster cluster is formed using the backend network addresses, and the nodes are added to the engine using the frontend network address.>>> Ok, so you definitely need two IPs. What is not clear to me is, do you need to have the IPs in different subnets or can they be in the same subnet? For reference, I was able to set this up with two IPs in the same subnet and it does seem to work. However, I have noted some slowness issues while connecting storage domains during startup and frequently get messages about needing to restart the HA agent. Usually it seems after I try to restart services I can get the system to recognize the engine storage domain and start the engine. I wonder if my problem is the fact that both my front and backend IPs are in the same subnet? Thanks for your advice.

Re: ovirt-engine-extension-aaa-ldap-setup failed
by Jeremy Tourville 15 Nov '18

The backend is 389 DS, no this is not Govt related. This will be used as a training platform for my local ISSA chapter. This is a new 389 DS server. I followed the instructions at https://www.unixmen.com/install-and-configure-ldap-server-in-centos-7/ The server is "stock" with the exceptions of the settings for startTLS and adding certificates, etc (basically, whatever is needed to integrate with the Ovirt Engine.) I am using my Admin account to perform the bind. What I don't understand is why everything else in the aaa setup script works except the login sequence. It would seem like my certificates are correct, correct use of the admin DN, etc. The funny part is I can login to the server using the admin account and password yet the same admin account and password fail when using the aaa setup script. But, that is why I am using the expert knowledge on the list! Maybe I have overlooked a simple prerequisite setting needed for setup somewhere? I'll wait for someone to chime in on possible reasons to get this message: SEVERE Authn.Result code is: CREDENTIALS_INVALID [ ERROR ] Login sequence failed ______________________________________________ Users mailing list -- users(a)ovirt.org<mailto:users@ovirt.org> To unsubscribe send an email to users-leave(a)ovirt.org<mailto:users-leave@ovirt.org> Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/TGT7ASCWSUTU6…

Separating VM network
by d.gengenbach＠patagona.de 14 Nov '18

14 Nov '18

We would like to separate our VM traffic completely from our host/storage network. As far as I can see, there is no definitive guide to achieve this by using VLANs/separate VM networks/subnetting. In our current setup: - the storage traffic happens in a separate VLAN (configured directly on the switch) on separate NICs on both hosts/storages in the 192.168.179.0/24 subnet - all other infrastructure (oVirt hosts, gateway, DHCP, DNS, VM thinclients, switches, ...) are in the 192.168.178.0/24 subnet We now want to separate the oVirt hosts/engine completely from the other infrastructure, eg. the VMs and thinclients. I am not experienced in networking and would be very thankful for all hints/tipps! Thanks in advance, David

Migrate datacenter with hosts and VM managed from engine no1 to engine no2
by Punaatua PK 14 Nov '18

14 Nov '18

Hello, we have the current setup. => 1 datacenter on site A with 1 cluster which is compose of 3 hosts and a self-hosted engine => 1 datacenter on site B (let's call this TATA) with 1 cluster compose of 3 hosts which is using glusterfs. This datacenter is managed by the self-hosted engine on site A We want to create on site B another datacenter with 1 cluster and another self-hosted engine then disengage datacenter TATA from self-hosted engine on site A. after that, we want to import all the ressource on the self-hosted engine on site B Is it possible to do this without loosing VM on glusterfs ? Off course VM will be shutdown during the operation. I mean, when a host is added on a new datacenter, ovirt will install package if necessary. Is there any way that ovirt manager erase actual configuration ? Is it safe to do this operation ?

Is it possible to update oVirt HCI environment automatically with ansible? If so are there any specific instructions or details on the process? Thanks!

Windows VM always growing
by Thomas Fecke 14 Nov '18

14 Nov '18

Hey Guys, we use, for our Windows VMs, "thin Provision". The Problem: the Disk always grow but if I delete Files in Windows the actual Disk size stays the same. Any way to get the "real" Windows Size back again? Some VMs got an Actual Size from about 100 GB - but Windows just got 25 GB Thanks in advanced Thomas

Engine trying to activate already activated hosts, causing serious instability...
by Jason P. Thomas 14 Nov '18

14 Nov '18

I've got a 4 node cluster running oVirt 4.2.7. 3 hosts are hyperconverged with glusterfs. Engine is running on one of the gluster volumes. Since yesterday, the cluster is completely unstable and will not reliably run VMs including the Engine. A notification will pop up in the WebUI stating "Finished invoking activate on host ovirt1" while the task list indicates "Activating host ovirt1". When this task ultimately fails, the node in question goes NonOperational. All our VMs have been down since 3pm yesterday, so help is greatly appreciated. Sincerely, Jason

LDAP Bind failing because of SSLHandshakeException after Virtualization Manager was rebooted
by wbhegedus＠gmail.com 14 Nov '18

14 Nov '18

After moving and rebooting our Red Hat Virtualization Manager box to another node in our cluster, we are unable to make LDAP login work using StartTLS. No networking or configuration changes were made, but the logs indicate that the TLS negotiation is failing with our Active Directory domain controllers now. Specifically: "2018-11-13 10:33:12,500-05 WARN [org.ovirt.engineextensions.aaa.ldap.Framework] (ServerService Thread Pool -- 49) [] Exception: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(sun.security.validator.ValidatorException: No trusted certificate found), ldapSDKVersion=4.0.5, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58" I have tried everything I can think of. I removed and reimported the certificate for the domain controller in the Java Keystore. I deleted the profile entirely and recreated it. I tried using the full certificate chain and I tried using single certificates from the chain, and all combinations together. For now, we have it working by specifying "pool.default.ssl.insecure = true" in the .properties file, but I'd prefer to have this working again using StartTLS. Is there something I am missing? I want to make sure that I'm not overlooking something before submitting any sort of bug report. Any help is appreciated. Thanks! PS - this is what the properties file looks like: [root@rhvm ~]# cat /etc/ovirt-engine/aaa/liberty.edu.properties include = <ad.properties> vars.domain = liberty.edu vars.user = cn=PREADER,ou=Service Accounts,ou=IS,OU=FSA,dc=University,dc=liberty,dc=edu vars.password = <redacted> pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} pool.default.serverset.type = srvrecord pool.default.serverset.srvrecord.domain = ${global:vars.domain} pool.default.ssl.startTLS = true pool.default.ssl.truststore.file = ${local:_basedir}/liberty.edu.jks
