ovirt 3.6 node
by Johan Kooijman 07 Mar '16

07 Mar '16

Hi all, I can't seem to find ovirt 3.6 node ISO. Is there a specific reason for this? I have the issue with 3.5 (ovirt-node-iso-3.5-0.201502231653.el7.iso) that I can't do live merge on machines installed with ovirt node. -- Met vriendelijke groeten / With kind regards, Johan Kooijman

Fresh install failing (Hosted Engine)
by Jonathan Sherman 07 Mar '16

07 Mar '16

I want to extend my lab and am trying an install using the hosted engine, but the install is failing for me: References used for install: https://glennsnead.wordpress.com/2016/02/28/ovirt-3-6-installation/ http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/ Setup: Minimal install of CentOS Linux release 7.2.1511 (Core) Using DHCP with static address (tried without DHCP with same issue) yum upgrade Installed packages: yum localinstall -y http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm yum install -y ovirt-hosted-engine-setup screen glusterfs-server nfs-utils vdsm-gluster system-storage-manager mailx rebooted Tried hosted-engine --deploy, but it errors out. I followed various logs and I _think_ it's failing related to vdsm-tool restore-nets. I could use some guidance on this to help track down what's happening and how to fix. (Note: I'd very much prefer using the hosted engine vs. another option for my lab, so I'm willing to put in the time to figure this out. Thanks for any assistance!)

Remove master storage from data center?
by nicolas＠devels.es 07 Mar '16

07 Mar '16

Hi, We've migrated storage from glusterfs to iSCSI, so now we have 2 storages in our data center. As we've already finished, we want to remove the gluster storage from our data center (which is the master storage right now). We've tried to put it on maintenance but we're getting this error: 2016-03-02 13:02:02,087 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.DisconnectStoragePoolVDSCommand] (org.ovirt.thread.pool-8-thread-34) [259a3130] Command 'DisconnectStoragePoolVDSCommand(HostName = ovirt01.domain.com, DisconnectStoragePoolVDSCommandParameters:{runAsync='true', hostId='c31dca1a-e5bc-43f6-940f-6397e3ddbee4', storagePoolId='fa155d43-4e68-486f-9f9d-ae3e3916cc4f', vds_spm_id='7'})' execution failed: VDSGenericException: VDSErrorException: Failed to DisconnectStoragePoolVDS, error = Operation not allowed while SPM is active: ('fa155d43-4e68-486f-9f9d-ae3e3916cc4f',), code = 656 Does that mean that *all* hosts must be on maintenance to do that? There's nothing left on the gluster storage right now. Thanks. Nicolás

Re: [ovirt-users] Update Self-Hosted-Engine - Right Way?
by Taste-Of-IT 07 Mar '16

07 Mar '16

Hello Simon, i am new with oVirt, but are you sure, that this is the way for the self-hosted-engine? Because i have no commands with hosted-***. As far as i understand the engine runs in self-hosted-engine on same host and therefore there is no way to enter the vm with engine and set it to maintenance mode.?!

some ISO images not recognized
by Stefano Cislaghi 07 Mar '16

07 Mar '16

Hello everyone, I configured a test environment with 2 hosts (centos), hosted engine and NFS storage for data domain and iso domain. I noticed that windows 2012 ISOs are marked as "unknown" in iso domain and##SELECTION_END## therefore I can't attach them to virtual machines. Maybe something is wrong with my iso? I tried to do a fresh download with same result. Centos, Fedora and Windows 10 iso are working, so I think the iso domain is ok. Did someone else noticed such behaviour? Any solution? Thanks Stefano

Testing openstack inside ovirt environment
by Gianluca Cecchi 06 Mar '16

06 Mar '16

Hello, Up to now I only tested openstack on physical hw. I would like to make some tests in a virtual environment. Not considering at the moment cinder and glance integrations provided by oVirt but full openstack itself. Are nestedvt and macspoof vdsm hooks the only requirement I should care about to be able to go? Also, supposing I go with a preliminar pre-test of openstack in virtual environment using plain qemu/kvm with virt-manager, it's clear to me how to enable the nested kvm for the host, but what should be the commands to give on host side so that the openstack instances will be able to communicate with the outside world (the commands that in ovirt I presume are run by the macspoof vdsm hook). Thanks in advance, Gianluca

Promiscuous Mode
by Clint Boggio 06 Mar '16

06 Mar '16

I am deploying an OpenVPN server in my OVirt environment and I've come to a dead stop with the developer support on a topic related to OVirt configuration. The developer wants me to put the VM's underlying NIC into promiscuous mode. I've seen this in a VMware environment and I know what they are asking me to do, and I'm wondering if there is a clear way to do this in my OVirt environment. I found "port mirroring" but no "promiscuous mode" Cheers and thank you !

set up of fibre channel storage problem
by Campbell McLeay 06 Mar '16

06 Mar '16

Hi, I've set up a node in a cluster which I would l like to use the attached fibre channel disks as storage. The ovirt version is 3.6 and both hosts (engine and node) are running Scientific 7.2. When I select the fibre channel option in the ovirt manager GUI from the drop down menu in the storage section, it shows the target disks on the node host (actually symlinks named as 34 character IDs which I assume are created by multipathd, which point to the actual device in /dev such as /dev/dm-3). 'multipath -ll' shows the devices up and running: 36f01faf000e5fd64000007d255820b3d dm-1 DELL ,MD36xxf size=5.7T features='2 pg_init_retries 50' hwhandler='1 rdac' wp=rw |-+- policy='service-time 0' prio=14 status=active | `- 8:0:0:3 sdi 8:128 active ready running `-+- policy='service-time 0' prio=9 status=enabled `- 1:0:0:3 sde 8:64 active ready running 36f01faf000e5fd5b000009fc52cc8a5b dm-2 DELL ,MD36xxf size=9.0T features='2 pg_init_retries 50' hwhandler='1 rdac' wp=rw |-+- policy='service-time 0' prio=14 status=active | `- 1:0:0:0 sdb 8:16 active ready running `-+- policy='service-time 0' prio=9 status=enabled `- 8:0:0:0 sdf 8:80 active ready running 36f01faf000e5fd640000078752cd9374 dm-0 DELL ,MD36xxf size=9.0T features='2 pg_init_retries 50' hwhandler='1 rdac' wp=rw |-+- policy='service-time 0' prio=14 status=active | `- 8:0:0:1 sdg 8:96 active ready running `-+- policy='service-time 0' prio=9 status=enabled `- 1:0:0:1 sdc 8:32 active ready running 36f01faf000e5fd5b00000a5a55820464 dm-3 DELL ,MD36xxf size=5.7T features='2 pg_init_retries 50' hwhandler='1 rdac' wp=rw |-+- policy='service-time 0' prio=14 status=active | `- 1:0:0:2 sdd 8:48 active ready running `-+- policy='service-time 0' prio=9 status=enabled `- 8:0:0:2 sdh 8:112 active ready running When I select those IDs, it says 'The following LUNs are in use' (does it perhaps mean by multipath?), and to 'Approve operation', which I do, but it then fails with: "Error while executing action New SAN Storage Domain: Physical device initialization failed.
