How to Configure and use OVS in Ovirt 4.1
by Pradeep Antil 31 Mar '17

31 Mar '17

Hello Folks, I want to use OVS as network switch in oVirt 4.1, While Creating a cluster i select OVS as switch type and all LAN ports of ovirt hosts or hypervisor are configured in trunk mode on the network switch. Logical networks are created and attached to the bond interface(consists of LAN cards of my hypervisor). [image: Inline image 1] In case of legacy network or Linux bridging either we usually assign the IP address or vlan id to logical network but while using OVS what needs to be used ..? Do i need to configure any other settings to use OVS. What i want to achieve with OVS is that i have around 10 VLANs and want to use these VLANs in different VMs in my oVirt Setup. If i go with Legacy switch then i have to create 10 different logical networks. Thanks in adavnce -- Best Regards Pradeep Kumar

oVirt node local storage behavior

Hello, I have one server where i was installe oVirt node 4.1 and used in my infrastructure. It's used as single server cluster with local storage configured. I created separate volume for it and mounted as separate directory: [root@virt4 ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert local_storage onn Vwi-aotz-- 350.00g pool00 7.27 ovirt-node-ng-4.1.0-0.20170201.0 onn Vri---tz-k 425.37g pool00 ovirt-node-ng-4.1.0-0.20170201.0+1 onn Vwi---tz-- 425.37g pool00 ovirt-node-ng-4.1.0-0.20170201.0 ovirt-node-ng-4.1.0-0.20170316.0 onn Vwi---tz-k 425.37g pool00 root ovirt-node-ng-4.1.0-0.20170316.0+1 onn Vwi---tz-- 425.37g pool00 ovirt-node-ng-4.1.0-0.20170316.0 ovirt-node-ng-4.1.1-0.20170322.0 onn Vri---tz-k 425.37g pool00 ovirt-node-ng-4.1.1-0.20170322.0+1 onn Vwi-aotz-- 425.37g pool00 ovirt-node-ng-4.1.1-0.20170322.0 2.17 pool00 onn twi-aotz-- 440.37g 18.44 9.91 root onn Vwi---tz-- 425.37g pool00 swap onn -wi-ao---- 7.88g var onn Vwi-aotz-- 15.00g pool00 16.28 mount: /dev/mapper/onn-local_storage on /local_storage type xfs (rw,relatime,seclabel,attr2,inode64,logbsize=256k,sunit=512,swidth=512,noquota) [root@virt4 ~]# ll / drwxr-xr-x. 3 vdsm kvm 76 Mar 23 09:02 local_storage All operations was done through cockpit UI With 4.1.1 upgrade i decided to upgrade it. After server reboot i discovered that my local storage folder was cleared, so i need to recreate all VMs and disks from scratch. Is this a bug or I did something wrong?

Guys, I have recently setup a new Ovirt environment, and i have created a gluster share for both my Export and ISO Domains. Every time i try and use either command, i get an access denied error.

How to update ovirt ng nodes
by Massimo Mad 30 Mar '17

30 Mar '17

Hi, How is the right procedure for upgrade the host from 4.0 to 4.1. I don't find any document with the right procedure, if i use the iso of the version 4.1 and i boot with this iso there is'nt the option on boot for upgrade. The problem is that it should be updated .repo file with the 4.1 release, but is supported ? How do you update the hosts ? Regards Massimo

Which I found doesn’t work with a local-install, either. (I was thinking it would work due to past experience with things that demand an old Postgres; IME, PG generally has pretty solid forward-compatibility.) In "local-install" you mean on the engine machine? >From RPMs? Instead of the OS-packaged PG (and not in parallel)? Were its binaries in /usr/bin (and not some private path)? If answers for all of the above are 'Yes', then please share setup logs, perhaps preferably by opening a bugzilla RFE and attaching them there. It's rather likely that whatever problems you had are quite easy to solve. Otherwise, please try that, or see the bug(s) below for a discussion about this. > > So that leads me to my next question: if I install under the supported version and dump/load/reconfigure to PG9.5.3, is anyone aware of any actual problems (other than lack of official support)? I personally didn't yet reach that point to be able to tell about, nor do I know about others that did, but see below. > In doing answerfile-driven installs repeatedly, the point where it now fails is after the DB load, with ovirt-aaa-jdbc-tool choking and failing the run. > > The reason I’m considering that as my fallback, nothing-else-worked option is that the DB needs to live in one of our existing clusters. We are a heavy Postres shop with a lot of hardware, humans and process devoted to maintaining it, and the DBAs would hang my corpse up as a deterrent to others if I started installing ancient instances in random places for them to take care of. If you do manage to make it work locally, then working with remote db should be easy, but does require (currently) to have the local client to be of the same version. Please see this bug, and the the ones it depends on: https://bugzilla.redhat.com/show_bug.cgi?id=1324882 Almost all of it is relevant for a "vanilla" 9.5. I am allowing myself to change the subject of current email, as I assume the original issue is concluded. Best, -- Didi

VDSM Hooks
by John 30 Mar '17

30 Mar '17

Hi, I've be googling and also trawling the oVirt documentation trying to find instructions on how to install and use VDSM hooks in general but specifically the "vdsm-hook-localdisk" hook. I have a machine that has a large amount of free space on SSD which I was hoping to use to store a pinned VM which requires fast I/O throughput and doesn't require HA. In essence, I'm trying to figure out how to use a hypervisor host as both a member of my cluster but also to provision a VM using local storage. If anybody could point me in the right direction I would be very grateful. Thanks John

Default Quota could not be updated nor removed in ovirt hosted engine 4.1
by Manuel Luis Aznar 30 Mar '17

30 Mar '17

Hello there, It seams that there is a bug with the Default Quota, as I reported in the subject of the email I am using oVirt Hosted Engine 4.1 When I tried to edit the Default Quota the system replies the following with Data Center in Audit Mode: Operation Canceled: Error while executing action: Cannot edit Quota. Quota is not valid. If I try to remove the Default Quota of the system, it replied: Operation Canceled: Error while executing action: Cannot remove Quota. Default quota cannot be changed. In the other hand if I do the same with the Data Center in Disabled Mode for Quota it says: Trying to edit Default Quota I got: Operation canceled: Error while executing action: Cannot edit Quota. Quota is not valid. Trying to remove Quota I got: Operation canceled: Error while executing action: Cannot remove Quota. Default quota cannot be changed. Of course I can create other Quotas, edit them and remove them. The problem is only with the Default Quota. Any help would be appreciated, either in unblocking the system to edit/remove Default quota... Thanks for all in advance, Manuel

oVirt 3.6 on CentOS 6.7 based HyperConverged DC : Upgradable?
by Nicolas Ecarnot 30 Mar '17

30 Mar '17

[Please ignore the previous msg] Hello, One of our DC is a very small one, though quite critical. It's almost hyper converged : hosts are compute+storage, but the engine is standalone. It's made of : Hardware : - one physical engine : CentOS 6.7 - 3 physical hosts : CentOS 7.2 Software : - oVirt 3.6.5 - glusterFS 3.7.16 in replica-3, sharded. The goal is to upgrade all this to oVirt 4.1.1, and also upgrade the OSes. (oV 4.x only available on cOS 7.x) At present, only 3 VMs here are critical, and I have backups for them. Though, I'm quite nervous with the path I have to follow and the hazards. Especially about the gluster parts. At first glance, I would go this way (feel free to comment) : - upgrade the OS of the engine : 6.7 -> 7.3 - upgrade the OS of the hosts : 7.2 -> 7.3 - upgrade and manage the upgrade of gluster, check the volumes... - upgrade oVirt (engine then hosts) But when upgrading the OSes, I guess it will also upgrade the gluster layer. During this upgrade, I have no constraint to keep everything running, total shutdown is acceptable. Is the above procedure seems OK, or may am I missing some essential points? Thank you. -- Nicolas ECARNOT _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
