NFS firewall rule
by Bill James 23 Mar '16

23 Mar '16

How do I make it that when ever I add or reinstall a hardware node that oVirt creates a rule for NFS, port 2049? I have to either add it manually after ovirt removes it, or just tell ovirt not to touch firewall rules. Our ISO domain is not hosted by the ovirt-engine, fyi. ovirt-engine-3.6.3.4-1.el7.centos.noarch

Re: [ovirt-users] Where to add NFS Data Storage

Hello Joop, thanks for help. I tried now with fresh installation, but i have to enter a first storage domain to the nfs path i created. So the question is which path i have to add in engine?

Shared storage

Hello list, I was wondering if any one could tell me if a Dell MD1400 Direct Attached Storage unit is suitable for shared storage between ovirt hosts? I really don't want to buy something that isn't going to work :) Regards, Brett

How to use /etc/ovirt-hosted-engine-setup.env.d/ ?
by Pat Riehecky 21 Mar '16

I'd like to pre-seed answers to several of the hosted-engine setup question, but can't seem to find any instructions on how to pass answers into hosted-engine. I tried the same tactics as with engine-setup, but those netted no results. Pat -- Pat Riehecky Scientific Linux developer Fermi National Accelerator Laboratory www.fnal.gov www.scientificlinux.org

Trouble configuring ISO domain on oVirt 3.5
by Hal Martin 21 Mar '16

21 Mar '16

Hello everyone, Please excuse me if this question has been asked before, I've searched the mailing list archives and can't find someone having the same problem as I am. I have a new oVirt installation that I'm trying to configure, and I cannot get the ISO domain I configured during engine-setup to show in the UI at all. Installation layout: # Engine CentOS 7 - oVirt Engine 3.5 (VM on different, non-oVirt cluster) # Nodes de-fra-p-hv05 - oVirt Node 3.5 de-fra-p-hv06 - oVirt Node 3.5 I installed and configured the engine, but the node that runs the engine is a VM, and will not be running VMs itself. I intend to use it only as a management node (in the VMWare world this would be analogous to the vCenter server). I don't want to run hosted engine because that requires me to install Fedora/CentOS on the blades. I would much rather have the engine live on a different cluster and just run oVirt node on the blades. I am able to install the nodes successfully, and configure them from within the engine UI. I am using an iSCSI SAN for VM storage. As per the Quick Setup guide, I have configured my iSCSI network on the nodes and created an iSCSI storage domain for VMs. Where I am utterly stuck is the creation of the ISO domain: http://www.ovirt.org/documentation/quickstart/quickstart-guide/#Attach_an_I… Since the server running oVirt engine is not participating in the cluster, it doesn't appear in my data center. This might be my problem, but I'm not sure. Here's a summary of the data center I have configured thus far: System |- Data Centers |- Default |- Storage |- sanQA |- Networks |- ovirtmgmt |- hpmsa |- vmnet128 |- Clusters |- QA |- Hosts |- de-fra-p-hv05 |- de-fra-p-hv06 I have edited the ACL on the server running oVirt engine to allow rw access on /var/lib/exports/iso to nodes de-fra-p-hv05 and de-fra-p-hv06. $ cat /etc/exports.d/ovirt-engine-iso-domain.exports /var/lib/exports/iso de-fra-p-ove01.domain.xyz(rw) /var/lib/exports/iso 172.20.102.215(rw) /var/lib/exports/iso 172.20.102.216(rw) When I try to import an ISO domain in the Data Center -> Storage tab, I get the following error: "Error while executing action: Cannot add Storage Connection. Storage connection already exists." Attached is the engine log from attempting to import the ISO domain. I don't have any ISO domain visible in the Storage tab of my data center. Since I cannot see the ISO domain in the UI, I cannot create new virtual machines on my cluster. Please help me understand what I've done wrong. I've also attached a screenshot of the management interface. As you can see, I've configured an iSCSI domain. I see no button in the UI to "Attach ISO" http://www.ovirt.org/documentation/quickstart/quickstart-guide/#Attach_an_I… Thank you, Hal

Diagnosing Migration Error
by Charles Tassell 20 Mar '16

20 Mar '16

Hello, I'm trying to test migrating a VM from one host to another and it's failing, but with no apparent error message. I took a look at the server logs (which I've copied below) but there doesn't seem to be anything in here that would help track down the problem. Should I be looking somewhere besides engine.log on the hosted engine? This is the latest version of oVirt (3.6.3.4-1.el7.centos) that I just upgraded this morning. The VM has an ISO attached over NFS storage and the disk image is on fiber channel. 2016-03-18 14:31:18,913 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (default task-25) [549545f2] Lock Acquired to object 'EngineLock:{exclusiveLocks='[2be4938e-f4a3-4322-bae3-8a9628b81835=<VM, ACTION_TYPE_FAILED_VM_IS_BEING_MIGRATED$VmName cdTest02>]', sharedLocks='null'}' 2016-03-18 14:31:19,131 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (org.ovirt.thread.pool-8-thread-45) [549545f2] Running command: MigrateVmToServerCommand internal: false.

The Foreman VM only uses 1GB at the beginning and MOM over time reduc= es the memory size from 8GB Ram to the defined minimum of 2GB  mom.log: 2016-03-18 12:25:42,669 - mom.Controllers.Balloon - INFO - Ballooning guest= :qvie-foreman from 2210584 to 2100054 2. When the VM needs RAM very quickly like if you do an 'cp /dev/zero /r= un/zero' the ovirt guest agent crashes with an out of memory error. ovirt-guest-agent.log: Traceback (most recent call last):   File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", li= ne 239, in doWork     self.sendUserInfo()   File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", li= ne 355, in sendUserInfo     cur_user =3D self.dr.getActiveUser()   File "/usr/share/ovirt-guest-agent/GuestAgentLinux2.py", l= ine 325, in getActiveUser     users =3D os.popen('/usr/bin/users').read().split() OSError: [Errno 12] Cannot allocate memory 3. Resulting in an MOM warning that it can't get any memory stats from the = VM. Leaving the memory size at its minimum size:. mom.log: mom.Collectors.GuestMemory - WARNING - getVmMemoryStats() error: The ovi= rt-guest-agent is not active Any chances to prevent that from happening? Or is this a bug in MOM / ov= irt-guest-agent that should be fixed? Greetings Andreas </div> </body> </html> --_000_AM3PR06MB12021070EF302BE6210F1A65828C0AM3PR06MB1202eurp_--
