Null object error with ovirt-engine-extension-ldap

Hello, After I adding a AD directory server to oVirt using manage-domains, I installed the extension-ldap package. My setup is as follows: 1. /etc/ovirt-engine/extensions.d/eayunos.properties ovirt.engine.extension.name = eayunos ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthzExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authz config.profile.file.1 = /usr/share/ovirt-engine-extension-aaa-ldap/profiles/ad.properties 2. restart ovirt But after that there is a error in engine.log: 2014-10-20 00:52:11,199 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'builtin-authn-internal' 2014-10-20 00:52:11,201 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'builtin-authn-internal' loaded 2014-10-20 00:52:11,202 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'internal' 2014-10-20 00:52:11,203 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'internal' loaded 2014-10-20 00:52:11,218 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'builtin-authn-eayunos.com' 2014-10-20 00:52:11,232 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'builtin-authn-eayunos.com' loaded 2014-10-20 00:52:11,245 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'eayunos.com' 2014-10-20 00:52:11,247 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'eayunos.com' loaded 2014-10-20 00:52:11,252 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'ovirtSyslog' 2014-10-20 00:52:11,253 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'ovirtSyslog' loaded 2014-10-20 00:52:11,257 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Loading extension 'eayunos' 2014-10-20 00:52:11,286 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'eayunos' loaded 2014-10-20 00:52:11,287 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Initializing extension 'builtin-authn-internal' 2014-10-20 00:52:11,288 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Extension 'builtin-authn-internal' initialized 2014-10-20 00:52:11,289 INFO [org.ovirt.engine.core.extensions.mgr.ExtensionsManager] (MSC service thread 1-16) Initializing extension 'eayunos' 2014-10-20 00:52:11,290 INFO [org.ovirt.engineextensions.aaa.ldap.Framework] (MSC service thread 1-16) Creating LDAP pool 'authz' for 'eayunos' 2014-10-20 00:52:11,305 ERROR [org.ovirt.engineextensions.aaa.ldap.AuthzExtension] (MSC service thread 1-16) Cannot initialize LDAP framework, deferring initialization.

ovIrt 3.5 -el6 - hosted-engine-ha upgrade: python-libguestfs dep issue
by Daniel Helgenberger 20 Oct '14

Hello, after upgrading to 3.5 I also upgraded to the lasted engine-ha and ran into this dependency issue. I just skipped it for the moment as I consider libguestfs not so much essential on the hosts. Error: Package: 1:python-libguestfs-1.20.11-2.el6.x86_64 (@base) Requires: libguestfs = 1:1.20.11-2.el6 Removing: 1:libguestfs-1.20.11-2.el6.x86_64 (@base) libguestfs = 1:1.20.11-2.el6 Updated By: 1:libguestfs-1.20.11-10.el6.x86_64 (ovirt-3.5) libguestfs = 1:1.20.11-10.el6 -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767

Best way for using Ubuntu 14 as a guest OS of oVirt 3.5.
by Fumihide Tani 19 Oct '14

19 Oct '14

Hi, everyone, I have found a big solution for using Ubuntu 14 as a guest of oVirt 3.5! Ubuntu 14 is troublesome on KVM and SPICE environment now. Known issues are: - missing letters from Ubuntu desktop title and menu - frequently VM goes too much cpu usage and no operationable If you want to solve these, simply do next: # sudo apt-get remove xserver-xorg-video-qxl then you will get everything goes fine! Good luck, Fumihide Tani

VSDM Hosts Swapspace

Hi All, As I'm not a big fan of swapping, as most people don't I think, I wonder why the following calculation is made: The default overcommit ratio is 0.5. The recommended size of the swap partition can be determined by: Multiplying the amount of system RAM by the expected overcommit ratio, and adding 2 GB of swap space for systems with 4 GB of RAM or less, or 4 GB of swap space for systems with between 4 GB and 16 GB of RAM, or 8 GB of swap space for systems with between 16 GB and 64 GB of RAM, or 16 GB of swap space for systems with between 64 GB and 256 GB of RAM. Example recommended SWAP calculation for a machine with 16 GB of RAM: (16 GB x 0.5) + 8 GB = 16 GB Would VM's make the Host swap that fast when the mem is overcommitted ? I have tested this and don't see much more than 1,5GB of swap usage. I hope someone can tell me how they see/use this. Matt

Hi Ryan, If you want to monitor your oVirt environment (storage domains, data centers, clusters, hosts) using Nagios you can use check_rhev3: https://github.com/ovido/check_rhev3 For monitoring virtual machines with Nagios it's possible to use this plugin as well, but I suggest other (more detailed) methods like nrpe, ssh, snmp or check_mk agent: http://mathias-kettner.de/checkmk.html You can also display all your Nagios check results in oVirt webadmin with the Monitoring UI-plugin: https://github.com/monitoring-ui-plugin/monitoring-ui-plugin Regards, René -----Original message----- From: Shirly Radco <sradco(a)redhat.com> Sent: Sun 10-19-2014 08:32 am Subject: Re: [ovirt-users] oVirt monitoring To: Ryan Nix <ryan.nix(a)gmail.com>; CC: users(a)ovirt.org; > Hi Ryan, > > You can use oVirt reports and dwh packages that collects historical data > and provides reports that enable you to monitor the system currently and over > time. > > http://www.ovirt.org/Ovirt_Reports > > Best regards, > --- > Shirly Radco > BI Software Engineer > Red Hat Israel Ltd. > > > ----- Original Message ----- > > From: "Mooli Tayer" <mtayer(a)redhat.com> > > To: "Ryan Nix" <ryan.nix(a)gmail.com> > > Cc: users(a)ovirt.org > > Sent: Saturday, October 18, 2014 8:27:30 PM > > Subject: Re: [ovirt-users] oVirt monitoring > > > > Hi Ryan, > > > > 1.)

CentOS 7 + oVirt 3.5 + OpenVPN

Hello: have installed oVirt 3.5 VDSM on a CentOS 7 node and then OpenVPN. The problem I have is that when I start OpenVPN I receive the message: Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip link set dev tun0 up mtu 1500 Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip addr add dev tun0 192.168.124.200/25 broadcast 192.168.124.255 Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1 Oct 18 13:29:50 kvm01 openvpn[4159]: ERROR: Linux route add command failed: external program exited with error status: 2 and if I run the route command manually: [root@kvm01 sysconfig]# /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1 RTNETLINK answers: No such process It would appear the tunnel is up: [root@kvm01 sysconfig]# ip add ls 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether f2:c9:ce:e5:ac:32 brd ff:ff:ff:ff:ff:ff 3: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UP qlen 1000 link/ether c8:1f:66:c4:2c:76 brd ff:ff:ff:ff:ff:ff inet6 fe80::ca1f:66ff:fec4:2c76/64 scope link valid_lft forever preferred_lft forever 4: em2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether c8:1f:66:c4:2c:77 brd ff:ff:ff:ff:ff:ff 6: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 46:af:6e:9a:1e:4b brd ff:ff:ff:ff:ff:ff 8: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether c8:1f:66:c4:2c:76 brd ff:ff:ff:ff:ff:ff inet XXX.XXX.XXX.XXX/23 brd 88.150.253.255 scope global ovirtmgmt valid_lft forever preferred_lft forever inet6 fe80::ca1f:66ff:fec4:2c76/64 scope link valid_lft forever preferred_lft forever 10: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 100 link/none inet 192.168.124.200/25 brd 192.168.124.255 scope global tun0 valid_lft forever preferred_lft forever Any thoughts as to why the route will not work ? Rationale for this approach is its a cloud server and wish to use a private network to reach the install VMs on that node. Thanks, Phil

oVirt monitoring
by Ryan Nix 19 Oct '14

19 Oct '14

Hello, I was looking for something to monitor the resources managed by oVirt and not necessarily oVirt itself. It looks like there is a page on Nagios integration, however, I'm getting a 503 when trying to access the site. http://www.ovirt.org/Features/Nagios_Integration Does anyone have any recommendations on monitoring resources managed by oVirt? Thanks, Ryn

iSCSI - recommended LUN size?
by Anthony Alba 18 Oct '14

18 Oct '14

Some noob questions on iSCSI as I am doing an evaluation on NFS vs iSCSI. 1. Is there a best practices guide to LUN sizing for oVirt? E.g. N x 200G, N x 500G, N x 1 TB. http://www.ovirt.org/Quick_Start_Guide#Create_an_iSCSI_Data_Domain "oVirt platform supports iSCSI storage domains spanning multiple pre-defined Logical Unit Numbers (LUNs)." 2. Since we can extend the storage domain, I was thinking of multiples of 200G. Any reason not to do it this way? >From the mailing list: https://www.mail-archive.com/users@ovirt.org/msg13638.html "please note: - you can extend a *storage domain* by adding an extra LUN to it from ovirt-engine." 3. Any production experience with LIO target/targetcli as backend? Thanks! - Anthony
