Hello LDAP Users, If you migrated from 3.4 or if you used engine-managed-domains to add LDAP support into engine - this message is for you. In 3.5 we introduced a new LDAP provider[1][2], it is superset of the previous implementation, highlights includes: * Better response times. * Simplicity, Use of LDAP protocol only - kerberos is no longer needed. * More LDAP implementations are supported. * Flexible configuration, can be customized on site to support special setups. * Supportability, better logs and feedbacks to enable remote support. * Variety of fallback policies, examples: srvrecord, failover, round-robin and more. * Active Directory: supports multiple domain in forest. In 3.5 the previous LDAP provider is marked as legacy, users' issues will be resolved by migration to the new provider. Upgrade to 4.0 will not be possible if legacy provider is being used. The new provider is working without any issue for quite some time, we would like to eliminate the remaining usage of the legacy provider as soon as possible. A tool was created[3] to automate the process, it should perform everything in safe and automatic process, while enables customization if such required. The one prerequisite that we could not automate easily is obtaining the CA certificate used by the LDAP server to communicate using SSL/TLS, you should acquire this manually and provide it as parameter. We (Ondra CCed and I) will help anyone that is experiencing issues with the process, please do not delay migration to the point it becomes emergency. Let's define a virtual goal -- in 1 month no legacy LDAP usage anywhere. Regards, Alon Bar-Lev.

I see oVirt 3.6 support HE on fibre channel, what if I have a SAS SAN? Is it supported as well?

Partition type
by Robert Fitzpatrick 09 Aug '15

I am brand new to Ovirt looking to migrate some virtual machines now on a KVM server and wanted to get some advice. Setting up my first CentOS 7 server following this document to have a self-hosted engine and storage... http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/ I've never used GlusterFS either and my question is what benefits it provides, why this doc suggests using it and how it could provide redundancy. The server has 4 SSD drives and a RAID controller, but is that beneficial and would using LVM be any benefit to store the partitions/bricks? Thanks for any advice. -- Robert

Ubuntu guest doesn't reboot properly
by Alan Murrell 07 Aug '15

07 Aug '15

I have an Ubuntu 14.04 guest (actually Zentyal server). Guest additions are installed from respository (and even displays the extra info like IP address, host name, memory use) in the oVirt dash board. Whenever I either reboot the guest or shut it down, it never seems to come up properly. It shows that it is powered on and it responds to ping, but I cannot SSH in (says connection refused). The SPICE console display just shows black with some slightly coloured bars in the upper left of the screen, so I am unable to determine what stage of the boot process it is on and/or if it is even at a login screen. I have a Windows 7 guest VM that reboots with no issue. I currently do not have another Linux guest VM to test with, but I plan on installing a Debian guest, CentOS guest, as well as a "vanilla" Ubuntu 14.04 guest to see if it is a Linux thing, and Ubuntu thing, or just something odd with the Zentyal spin of Ubuntu. I will report on my results (it may take a bit), but I wanted to check here to see if anyone else has already troubleshot this and what the findings and conclusions were? Thanks! :-) -Alan

automatic migration on power failure

------=_Part_598468_413451903.1438073708663 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, is ovirt by default not capable of automatic migration or automatic restarting of VMs on different host during host's power failure? because i remember having this problem on hosted-engine setup wherein my engine as well as the other virtual machines won't automatically start on different host when i for example switch off the server hosting the VMs. migration when host switched to maintenance works fine as well as the migration using the cluster policy. HA option on VM also works fine, but it only restarts on the same host. below is our current setup. 1 SuperMicro X7DBR-3 (Engine ovirt 3.5.1.1-1.el6) 6 IBM S5000PAL (Hosts) FreeNAS multipath iSCSI for data storage kvm 0.12.1.2 - 2.448.el6_6.4 libvirt libvirt-0.10.2-46.el6_6.6 vdsm vdsm-4.16.20-1.git3a90f62.el6 Thanks, Jaicel ------=_Part_598468_413451903.1438073708663 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable <html><body><div style=3D"font-family: arial, helvetica, sans-serif; font-s= ize: 10pt; color: #000000"><div>Hi,<br></div><div><br data-mce-bogus=3D"1">= </div><div>is ovirt by default not capable of automatic migration or automa= tic restarting</div><div>of VMs on different host during host's power failu= re? because i remember having<br data-mce-bogus=3D"1"></div><div>this probl= em on hosted-engine setup wherein my engine as well as the other<br data-mc= e-bogus=3D"1"></div><div>virtual machines won't automatically start on diff= erent host when i for example<br data-mce-bogus=3D"1"></div><div>switch off= the server hosting the VMs.</div><div><br data-mce-bogus=3D"1"></div><div>= migration when host switched to maintenance works fine as well as the migra= tion</div><div>using the cluster policy.
