[Users] Not enough MAC addresses left in MAC Address Pool
by Thomas Scofield 27 Oct '13

27 Oct '13

While building a virtual machine we ran into an error "Not enough MAC addresses left in MAC Address Pool." In the engine log I see this message. 2013-10-26 14:47:16,590 WARN [org.ovirt.engine.core.bll.network.vm.AddVmInterfaceCommand] (ajp--127.0.0. 1-8702-12) [6fc05fa4] CanDoAction of action AddVmInterface failed. Reasons:VAR__TYPE__INTERFACE,VAR__ACTI ON__ADD,MAC_POOL_NOT_ENOUGH_MAC_ADDRESSES 2013-10-26 14:47:16,591 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (ajp--127.0 .0.1-8702-12) Operation Failed: [Not enough MAC addresses left in MAC Address Pool.] This led me to look at the engine config where I see these MacPoolRanges: 00:1A:4A:97:5E:00-00:1A:4A:97:5E:FF version: general MaxMacsCountInPool: 100000 version: general The MacPoolRange would seem to be the limiting factor here, cutting us off at 256 MAC addresses, which happens to be the number of virtual machine we currently have. I assume that updating the MacPoolRange and restarting the engine would resolve this issue. Has anybody experienced this issue? Why would the pool size have 256 and the Max entry be set to 100000, that seems like a large difference.

[Users] so, what do you want next in oVirt?
by Itamar Heim 26 Oct '13

26 Oct '13

earlier in the year we did a survey for feature requests / improvements / etc. since a lot of things were added, and priorities usually change, I'd like to ask again for "what do you need the most from oVirt / what are your pain points" next? below[1] I've listed my understanding of what already went in from previous survey requests (to various degrees of coverage). Thanks, Itamar [1] from the top 12 V Allow disk resize V Integrate Nagios/Zabbix monitoring - via a ui plugin V Highly Available engine - via hosted engine[2] V Open vSwitch integration - via neutron integration X Allow cloning VMs without template ? Enable hypervisor upgrade/updates through engine[3] V Allow engine on an oVirt hosted VM - via hosted engine[2] V Enable guest configuration (root password, SSH keys, network) via guest agent in engine - via cloud-init X Integrate v2v into engine ? Bond/extend ovirtmgmt with a second network for HA/increased bandwidth[4] X Integrate scheduling of snapshots and VM export for backups in engine[5] V Spice – support Google Chrome - via mime based launch Other items mentioned in previous survey which should be covered by now: - Fix timeout when adding local host during all-in-one configuration - Fix engine set-up when SELinux is disabled - Provide packages for el6 (CentOS, Red Hat Enterprise Linux) - Allow multiple VMs to be deployed from the same template at the same time - ISO domains on local/GlusterS - Show IP addresses in Virtual Machines->Network Interfaces - OpenStack Quantum support (now called Neutron) - noVNC support - Support spice.html5 and websocket proxy - Add other guest OSes to list - Port oVirt guest agent to Ubuntu[6] - SLA - Allow resource time-sharing - Spice - Mac client (via mime based launch) - Spice - port XPI plug-in to Windows (not sure this will happen, but mime based launch allows using firefox now) - Spice - client for Ubuntu/Debian (should be covered via mime based launch) [2] hosted engine is in active development, but not released yet. [3] host update is supported, but not for general yum update. [4] a lot of improvements were done in this space, but i'm not sure if they cover this exact use case [5] backup api is now being pushed to master, and orchestration of backups should probably happen via 3rd part backup vendors? [6] I'm not sure packaging exists yet, but ubuntu is covered for the basic functionality of the guest agent.

Hello I just thought I'd send a quick message to say Hi and to see if anyone on here is using Ovirt with Dell EqualLogic as the back-end storage. If anyone is having difficulty getting up and running this may be helpful: https://sites.google.com/a/keele.ac.uk/partlycloudy/ovirt/gettingovirttowor… Any feedback is welcome.

[Users] Docker -- self-sufficient application containers
by Greg Sheremeta 25 Oct '13

25 Oct '13

I haven't looked into this very much, but it sounds promising. Anyone on list familiar with it? http://www.docker.io/ "Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more." I wonder if there's interest in shipping oVirt docker containers. Greg Sheremeta Red Hat, Inc. Sr. Software Engineer, RHEV Cell: 919-807-1086 gshereme(a)redhat.com

[Users] Cant remove image -> Illegal Disk
by Andrew Lau 24 Oct '13

24 Oct '13

Hi, There were a few posts earlier about this but none seemed to end in a resolution. When a VM is destroyed the disks don't get deleted by oVirt and are left in an "illegal" state. Manual intervention is required to delete the image and remove it from the database. This has only happened recently, but I'm not sure what broke it. I assume it's the engine which handles the deletion of the disks. Here's a snippet of the log, where 78605656-f77c-4b72-843b-1 is the image id cat engine.log | grep '78605656-f77c-4b72-843b-1' 2013-10-24 21:12:33,141 ERROR [org.ovirt.engine.core.bll.RemoveAllVmImagesCommand] (pool-6-thread-43) Cant remove image id: 78605656-f77c-4b72-843b-1efef9644cf2 for VM id: aa21dd3c-6341-4d48-9819-112dbdf6f2db from domain id: 6682d31f-39ce-4896-99ef-14e1c9682585 due to: StorageDomainLayoutError. 2013-10-24 21:12:33,142 INFO [org.ovirt.engine.core.bll.RemoveAllVmImagesCommand] (pool-6-thread-43) Image id: 78605656-f77c-4b72-843b-1efef9644cf2 is not on a data domain and will not be marked as illegal. 2013-10-24 21:12:33,145 INFO [org.ovirt.engine.core.bll.RemoveVmCommand] (pool-6-thread-43) Command [id=e15c6804-d2e5-44b0-8fb9-6ad03421cd43]: Compensating CHANGED_STATUS_ONLY of org.ovirt.engine.core.common.businessentities.Image; snapshot: EntityStatusSnapshot [id=78605656-f77c-4b72-843b-1efef9644cf2, status=ILLEGAL].
