[oVirt3.5] Let me know how to integrate oVirt 3.5 with latest version of OpenLDAP.
by Fumihide Tani 18 Sep '14

Hi, everyone, I'm trying to integrate oVirt 3.5 RC2 with latest OpenLDAP 2.4. Both are running on a same server, CentOS 6.5 (Final), oVirt Engine server. But the integration does not succeed. First, I set up OpenLDAP according to the following url: http://www.ovirt.org/LDAP_Quick_Start. And many errors occurred during setup. (like: ldap_modify: Other (e.g., implementation specific) error (80) ). Next, I installed ovirt-engine-extension-aaa-ldap.noarch 0.0.0-0.0.master.20140904095149.gitc7bd415.el6 by yum. Then I set up ovirt-engine-extension-aaa-ldap according to the following url: https://www.mail-archive.com/devel@ovirt.org/msg01449.html After restarting ovirt-engine, the engine.log output: engine.log:2014-09-18 16:35:09, 691 INFO [org.ovirt.engineextensions.aaa.ldap. Framework] (MSC service thread 1-6) Creating LDAP pool 'authz' for 'authn-company'' Error is not detected here. Access to OpenLDAP server succeeded, and the user authentication succeeded too. I think that the cause of failing OpenLDAP integration is OpenLDAP side and the document http://www.ovirt.org/LDAP_Quick_Start is old and not fit to the latest version of OpenLDAP. If anyone know the latest document for the OpenLDAP integration or any help for resolving this problem, please let me know. Very thanks.

[OVIRT-3.5-TEST-DAY-3] : fence kdump integration
by Eli Mesika 18 Sep '14

18 Sep '14

I was testing fence kdump integration. Due to the following issues I was not able to test over JSON RPC and all tests were done with XML RPC 1) Manually applied : http://gerrit.ovirt.org/#/c/32843 (this was not included yet in 3.5 and cause an exception in VDSM when fenceNode is called) 2) JSON : does not return status correctly : Test Succeeded, null Therefor , can not stop/start/restart host Related to engine patch : http://gerrit.ovirt.org/#/c/32855/ not back-ported yet to 3.5 (blocker IMO) -------------------------------------------------------------- ALL tests below should be redone after resolving JSON issues ! -------------------------------------------------------------- ------------------- General comment ------------------- All fence kdump flows are related to a scenario in which host became non responsive. In the case of manual PM action (stop/restart) fence kdump is not taking place. I think this should be fully documented in order to prevent misunderstanding when the kdump flag is checked and host is rebooted/stopped manual while kdumping' which will result in losing the dump file. ********************************* Tests using XML RPC ********************************* ------------------------ Installation tests : ------------------------ 1) Adding a host with Detect kdump flow set to on and without crashkernel command line parameter Result: host installation is OK, but warning message is displayed in Events tab and Audit log TEST PASSED 2) Adding a host with Detect kdump flow set to on, with crashkernel command line parameter, but without required version of kexec-tools package Result: host installation is OK, but warning message is displayed in Events tab and Audit log TEST PASSED 3) Adding a host with Detect kdump flow set to on, with crashkernel command line parameter and with required version of kexec-tools package Result: host installation is OK, in General tab of host detail view you should see Kdump Status: Enabled TEST PASSED ------------------------ Kdump detection tests: ------------------------ 1) Crashdumping a host with kdump detection disabled Prerequisites: host was successfully deployed with Detect kdump flow set to off, fence_kdump listener is running Result: Host changes its status Up -> Connecting -> Non Responsive -> Reboot -> Non Responsive -> Up, hard fencing is executed TEST PASSED 2) Crashdumping a host with kdump detection enabled Prerequisites: host was successfully deployed with Detect kdump flow set to on, fence_kdump listener is running Result: Host changes its status Up -> Connecting -> Non Responsive -> Kdumping -> Non Responsive -> Up, hard fencing is not executed, there are messages in Events tab Kdump flow detected on host and Kdump flow finished on host TEST PASSED 3) Crashdumping a host with kdump detection enabled but fence_kdump listener down Prerequisites: host was successfully deployed with Detect kdump flow set to on, fence_kdump listener is not running Result: Host changes its status Up -> Connecting -> Non Responsive -> Reboot -> Non Responsive -> Up, hard fencing is executed, there's message in Events tab Kdump detection for host had started, but fence_kdump listener is not running TEST PASSED 4) Host with kdump detection enabled, fence_kdump listener is running, but network between engine and host is down Prerequisites: host was successfully deployed with Detect kdump flow set to on, fence_kdump listener is running, alter firewall rules on engine to drop everything coming from host's IP address Result: Host changes its status Up -> Connecting -> Non Responsive -> Reboot -> Non Responsive -> Up, hard fencing is executed, there's message in Events tab Kdump flow not detected on host TEST PASSED 5) Crashdumping a host with kdump detection enabled, fence_kdump listener is running, stop fence_kdump listener during kdump Prerequisites: host was successfully deployed with Detect kdump flow set to on, fence_kdump listener is running Actions: When host status is changed to Kdumping, stop fence_kdump listener Result: Host changes its status Up -> Connecting -> Non Responsive -> Kdumping -> Reboot -> Non Responsive -> Up, hard fencing is executed, there are messages in Events tab Kdump flow detected on host and Kdump detection for host had started, but fence_kdump listener is not running TEST PASSED I got this message in event log : Unable to determine if Kdump is in progress on host 'pluto-vdsf', because fence_kdump listener is not running. Is this OK ? 6) Crashdumping a host with kdump detection enabled, fence_kdump listener is running, restart engine during kdump Prerequisites: host was successfully deployed with Detect kdump flow set to on, fence_kdump listener is running Actions: When host status is changed to Kdumping, restart engine Result: Host changes its status Up -> Connecting -> Non Responsive -> Kdumping, hard fencing is not executed, there are messages in Events tab Kdump flow detected on host, after engine restart host stays in Kdumping status for the period of DisableFenceAtStartupInSec seconds, after that there are messages in Events tab Kdump flow detected on host and Kdump flow finished on host and changes status Kdumping -> Non Responsive -> Up TEST PASSED I got only this message in event log : Kdump flow is in progress on host 'pluto-vdsf'. Is this OK? Thanks Eli Mesika

[OVIRT-3.5-TEST-DAY-3] Node Hosted Engine
by Liron Aravot 18 Sep '14

18 Sep '14

Hi All, Federico and I tested the node hosted engine. We started a vm using the posted ovirt node iso and actually didn't get to test the complete hosted engine setup due to failure which was unclear [3] (opened a bug for that). Bug were opened for clarity of the node menu as well [1], same as for the way to access the logs [2]. thanks, [1] https://bugzilla.redhat.com/show_bug.cgi?id=1143857 [2] https://bugzilla.redhat.com/show_bug.cgi?id=1143861 [3] https://bugzilla.redhat.com/show_bug.cgi?id=1143871

[OVIRT-3.5-TEST-DAY-3] backup/restore/dr + Node
by Ryan Barry 18 Sep '14

18 Sep '14

I installed a fresh engine on CentOS 6.5, and 3.5 nodes on two nested VMs. A significant portion of the day was spent testing basic Node functionality to ensure we didn't have any more SELinux denials, install problems on EFI, or other issues, after which I moved onto engine. DR was simply tested by pulling the network cable in the middle of an operation, disconnecting both nodes and waiting for storage arbitration to succeed, and uncleanly terminating the VM running engine then restarting. Backup and restore was tested with ovirt-engine-backup (which I haven't used before, and is quite nice).

OVIRT-3.5-TEST-DAY-3 - hosted engine over iSCSI
by Antoni Segura Puimedon 18 Sep '14

18 Sep '14

Hi list! I got hold of an iSCSI lun and set out to test deploying the hosted-engine over it (I've been successfully running hosted-engine over NFS since oVirt-3.4 and have successfully upgraded it to 3.5 and jsonrpc communication). Unfortunately, things didn't start well with a small issue when calling hosted-engine --deploy Due to the vdsm certs not being propertly generated: https://bugzilla.redhat.com/1142696 After working around that doing: vdsm-tool configure --force I repeated the deploy command and answered every question. It created the VM image, but ultimately failed to set up a password for VNC (for that is what I chose to access the VM). https://bugzilla.redhat.com/1142710 I attached the vdsm logs and will investigate more to try to give more info to the hosted engine devs ;-) Regards, Toni

OVIRT-3.5-TEST-DAY-3 Instance types
by Alexander Wels 17 Sep '14

17 Sep '14

Hi, For the 3rd test day I was assigned to test the new instance types. The following instance types are available: custom: Aka what it was before tiny: 512M memory and 1 cpu small: 2048M memory and 1 cpu medium: 4096M memory and 1 cpu large: 8192M memory and 2 cpus x-large: 16384M memory and 4 cpus I verified that each selection modifies the properties accordingly. As well as the ability to change instance types after creating the VMs and that those changes are reflected. If you change a property lets say the memory after selecting an instance type it changes to custom automatically but keeps all the other pre-selected options the same. The only thing that won't change the instance type to custom if you change the 'optimized for' from server to desktop. This normally changes the soundcard enabled check box in the console tab but if an instance type is selected it doesn't. I don't know if this is on purpose or not. So all in all it works as expected, with a potential minor issue. Alexander
