[Users] RFE question
by Jakub Bittner 21 Nov '13

21 Nov '13

Hello, I would like to ask how to post RFE to oVirt. I know about google spreadsheet, but should I post RFE to users mailing list and after some discussion post it to bugzilla? I have 2 rfe on oVirt web interface: 1) I think that nice to have feature would be to have fourth column with disk usage in Virtual Machine tab. 2) Great improvement wold also be possibility to sort Virtual Machine tab by clicking on column name. For example: When I click on "Memory" all VMs get sorted by memory usage. If this RFE already exists, I am sorry. But I did not find it. Thank you.

[Users] Problem with host
by Koen Vanoppen 20 Nov '13

20 Nov '13

Hello All, I was a little bit to enthusiastic and removed a Test-Datacenter with 1 test cluster and 1 host in it. Now I have these error messages (but the host doesn't exist anymore) : Host apollo01 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" Alerts (2) Events Tasks (0) 2013-Nov-19, 10:37 Host apollo01 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" And on top of that, I can't re-add the host, because oVirt still things he is present.. Anybody knows a solution to this issue? Kind Regards, Koen

[Users] CfP: Virtualisation and IaaS DevRoom at FOSDEM'14
by Itamar Heim 20 Nov '13

20 Nov '13

https://groups.google.com/forum/#!forum/fosdem14-virt-and-iaas-devroom Call for Participation The scope for this devroom is open source, openly-developed projects in the areas of virtualisation and IaaS type clouds, ranging from low level to data center, up to cloud management platforms and cloud resource orchestration. Sessions should always target a developer audience. Bonus points for collaborative sessions that would be appealing to developers from multiple projects. We are particularly interested in the following themes: - low level virtualisation aspects - new features in classic and container-based virtualisation technologies - new use cases for virtualisation, such as virtualisation in mobile, automotive and embedded in general - other resource virtualisation technologies: networking, storage, … - deep technical dives into specific IaaS or virtualisation management projects features - relationship between IaaS projects and specific dependencies (not just virtualisation) - integration and development leveraging solutions from multiple projects Important dates Submission deadline: Sunday, December 1st, 2013 Acceptance notifications: Sunday, December 15th, 2013 Final schedule announcement: Friday January 10th, 2014 Devroom @ FOSDEM'14: February 1st & 2nd, 2014 Practical Submissions should be 40 minutes, and consist of a 30 minute presentation with 10 minutes of Q&A or 40 minutes of discussions (e.g., requests for feedback, open discussions, etc.). Interactivity is encouraged, but optional. Talks are in English only. We do not provide travel assistance or reimbursement of travel expenses for accepted speakers. Submissions should be made via the FOSDEM submission page at https://penta.fosdem.org/submission/FOSDEM14 : - If necessary, create a Pentabarf account and activate it - In the “Person” section, provide First name, Last name (in the “General” tab), Email (in the “Contact” tab) and Bio (“Abstract” field in the “Description” tab) - Submit a proposal by clicking on “Create event" - Important! Select the "Virtualisation and IaaS" track (on the “General” tab) - Provide the title of your talk (“Event title” in the “General” tab) - Provide a 250-word description of the subject of the talk and the intended audience (in the “Abstract” field of the “Description” tab) - Provide a rough outline of the talk or goals of the session (a short list of bullet points covering topics that will be discussed) in the “Full description” field in the “Description” tab Contact For questions w.r.t. the Virtualisation and IaaS DevRoom at FOSDEM'14, please contact the organizers via fosdem14-virt-and-iaas-devroom(a)googlegroups.com (or via https://groups.google.com/forum/#!forum/fosdem14-virt-and-iaas-devroom)

I saw that openldap is now listed as a provider when invoking engine-manage-domains. I'm eager to find more information about this. Does anyone know if there is any updated documentation floating around somewhere ? Found this: http://www.ovirt.org/LDAP_Quick_Start But the article seem only half-finished. Rgds Jonas

[Users] Fence-virt support
by Sander Grendelman 18 Nov '13

18 Nov '13

I'm currently building a ovirt test-environment using nested virtualization on libvirt/kvm. For the most part this works great. However, I can't configure fencing/power management because only hardware BMC's/fencing devices are supported. Is this something that could/should be included in a future oVirt version? Or is there another option/workaround to test power management?

Hi, we're going to branch and build oVirt 3.3.2 beta on Nov 27th. A bug tracker is available at [1] and it shows only 2 bugs blocking the release: Bug 1029792 - VDSM does not report the qemu version in capabilities, if qemu-kvm-rhev is used Bug 1029885 - cloud-init testcase does not work in engine 3.3.1 The following is a list of the bugs still open with target 3.3.2 or 3.3: Whiteboard Bug ID Summary 991267 [RFE] Add TUI information to log file. infra 987982 When adding a host through the REST API, the error message says that "rootPassword" is required, but ... infra 1017267 Plaintext user passwords in async_tasks database infra 1020344 Power Managent with cisco_ucs problem infra 1009899 exportDbSchema scripts generates output file with wrong name infra 1029792 VDSM does not report the qemu version in capabilities, if qemu-kvm-rhev is used integration 1026933 pre-populate ISO domain with virtio-win ISO integration 1026930 Package virtio-win and put it in ovirt repositories integration 1030437 RFE: Configuration of email notifications integration 1022440 AIO - configure the AIO host to be a gluster cluster/host integration 902979 ovirt-live - firefox doesn't trust the installed engine integration 1021805 oVirt Live - use motd to show the admin password network 988002 [oVirt] [network] Add button shouldn't appear on specific network network 987916 [oVirt] [provider] Dialog doesn't update unless focus lost network 987999 [oVirt] [provider] Add button shouldn't appear on specific provider network 906313 [oVirt-webadmin] [setupNetworks] "No valid Operation for <network_name> and Unassigned Logical Networks panel" network 1023722 [oVirt-webadmin][network] Network roles in cluster management should be radio buttons network 997197 Some AppErrors messages are grammatically incorrect (singular vs plural) storage 1016118 async between masterVersion : can't connect to StoragePool storage 987917 [oVirt] [glance] API version not specified in provider dialog storage 1029069 Live storage migration snapshot removal fails, probably due to unexpected qemu-img output ux 906394 [oVirt-webadmin] [network] Loading animation in network main tab 'hosts' and 'vms' subtab is stuck on first view... virt 1007940 Cannot clone from snapshot while using GlusterFS as POSIX Storage Domain Please set the target to 3.3.2 and add the bug to the tracker if you think that 3.3.2 should not be released without it fixed. Please also update the target to 3.3.3 or any next release for bugs that won't be in 3.3.2: it will ease gathering the blocking bugs for next releases. For those who want to help testing the bugs, I suggest to add yourself as QA contact for the bug and add yourself to the testing page [2].

[Users] Fencing virtual machines
by Nicolas Ecarnot 18 Nov '13

18 Nov '13

Hi, In the case I want to setup a virtual cluster amongst many virtual machines, and this virtual cluster needs to fence some VM, what is the best way to achieve this? I guess this has to use something like vdsClient to "unplug" the VM, but I found it hard to find any more information about this. -- Nicolas Ecarnot

Should we be able to > attach to those vms (e.g. win and winbak)? (if you see a behavior change in ovirt, you an also ask/cc on users(a)ovirt.org) in 3.0 we only allowed admin access to the API. in 3.1 we added user level access. main difference is users only get entities they have permissions with User Role on. an user with admin role can ask to get 'all', or just "me as a user" - all VMs which that admin has a User Role to. to not break api backward compatibility, default mode of the API remained 'admin mode', so you need to pass to the API "filter=true" to behave as a user.

[Users] Info on snapshot removal operations and final disk format
by Gianluca Cecchi 17 Nov '13

17 Nov '13

Hello, I'm on oVirt 3.2.3-1 on a Fedora 18 all-in-one test server. I have a Windows XP VM that has a disk in qcow2 format and has a snapshot on it. When I delete the snapshot I see, from the commands intercepted, that the final effect is to have a raw disk (aka preallocated) .... is this correct and always true? Does this mean that even if I create a VM with thin provisioned disks, as soon as I take at least one snapshot and I then delete it I only have raw disks? Or am I missing anything? This what I observed: as soon as I launch delete snapshot operation: raw format of new disk vdsm 30805 1732 6 13:24 ? 00:00:00 /usr/bin/dd if=/dev/zero of=/rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE bs=1048576 seek=0 skip=0 conv=notrunc count=11264 oflag=direct after about 5 minutes: convert from qemu format to raw format vdsm 31287 1732 7 13:29 ? 00:00:08 /usr/bin/qemu-img convert -t none -f qcow2 /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 -O raw /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE at the end probably there is a rename of the disk file and qemu-img info /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 image: /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 file format: raw virtual size: 11G (11811160064 bytes) disk size: 9.5G # ll /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/ total 9995476 -rw-rw----. 1 vdsm kvm 1048576 Nov 16 12:09 6ac73ee2-6419-43a4-91e7-7d4ef2026943_MERGE.lease -rw-rw----. 1 vdsm kvm 11811160064 Nov 16 13:32 d4fa7785-8a89-4d13-9082-52556ab0b326 -rw-rw----. 1 vdsm kvm 1048576 Mar 23 2013 d4fa7785-8a89-4d13-9082-52556ab0b326.lease -rw-rw----. 1 vdsm kvm 1048576 Nov 16 13:29 d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE.lease -rw-r--r--. 1 vdsm kvm 274 Nov 16 13:29 d4fa7785-8a89-4d13-9082-52556ab0b326.meta Thanks Gianluca

Without knowing how the disks are split among the controllers, I don't want to make any assumptions about how shared it actually is, since it may be half and half with no multipathing. While a multi-controller DAS array *may* be shared storage, it may not be. Moreover, I have no idea whether VDSM looks at by-path, by-bus, dm-*, or otherwise, and there are no guarantees that a SAS disk will present like a FC LUN (by-path/pci...-fc-$wwn...), whereas OCFS POSIXFS is assured to work, albeit with a more complex setup and another intermediary layer.

The array you have is the effective equivalent of attaching additional hard drives directly to your computer. It is not necessarily faster than iSCSI or Fiber Channel; almost any nearline storage these days will be SAS, almost all the SANs in production, and most of the tiered storage as well (because SAS supports SATA drives). I'm not even sure if NetApp uses FC-AL drives in their arrays anymore. I think they're all SAS, but don't quote me on that. What differentiates a SAN (iSCSI or Fiber Channel) from a NAS is that a SAN presents raw devices over a fabric or switched medium rather than point-to-point (point-to-point Fiber Channel still happens, but it's easier to assume that it doesn't for the sake of argument). A NAS presents network file systems (CIFS, GlusterFS, Lustre, NFS, Ceph, whatever), though this also gets complicated when you start talking about distributed clustered network file systems. Anyway, what you have is neither of these. It's directly-attached storage. It may work, but it's an unsupported configuration, and is only shared storage in the sense that it has multiple controllers. If I were going to configure it for oVirt, I would: Attach it to a 3rd server and export iSCSI LUNs from it Attach it to a 3rd server and export NFS from it Attach it to multiple CentOS/Fedora servers, configure clustering (so you get fencing, a DLM, and the other requisites of a clustered filesystem), and use raw cLVM block devices or GFS2/OCFS filesystems as POSIXFS storage for oVirt.

[Users] Low quality of el6 vdsm rpms
by Patrick Hurrelmann 16 Nov '13

16 Nov '13

Hi all, sorry for this rant, but... I now tried several times to test the beta 3.3.1 rpms, but they can't even be installed in the most times. One time it required a future selinux-policy, although the needed selinux fix was delivered in a much lower version. Now the rpms have broken requirements. It requires "hostname" instead of "/bin/hostname". This broken requirement is not included in the vdsm 3.3 branch, so I wonder where it comes from? Anyway. So I proceeded and tried to build vdsm myself once again. Currently the build fails with (but worked fine some days ago): /usr/bin/pep8 --exclude="config.py,constants.py" --filename '*.py,*.py.in' \ client lib/cpopen/*.py lib/vdsm/*.py lib/vdsm/*.py.in tests vds_bootstrap vdsm-tool vdsm/*.py vdsm/*.py.in vdsm/netconf vdsm/sos/vdsm.py.in vdsm/storage vdsm/vdsm vdsm_api vdsm_hooks vdsm_reg vdsm/storage/imageRepository/formatConverter.py:280:29: E128 continuation line under-indented for visual indent - How can the quality of the vdsm builds be increased? It is frustrating to spend time on testing and then the hosts cannot even be installed to broken vdsm rpms. - How are the builds prepared? Is there a Jenkins job that prepares "stable" rpms in addition to the nightly job? Or is this totally handcrafted? - How can it be that the rpm spec differs between the 3.3 branch and released rpms? What is the source/branch for el6 vdsm rpms? Maybe I'm just tracking on the wrong source tree...

Re: [Users] from irc
by Bob Doolittle 15 Nov '13

Hi, I had a question on IRC regarding sysprep/sealing of Windows VMs and use in Pools. Basically, if you follow the Quick Start Guide, it says to seal the VM and shut it down before making the Template. My problem with this is that when you start a VM from the Pool, it takes forever to unseal - i.e. to repersonalize itself. That's a bad experience from a VDI perspective - you want the user to get a desktop they can start using ASAP. Itamar responded to me directly via e-mail: > bobdrad: on your question of windows VMs from pool - you can start > them once with an admin for the sysprep to happen, then shut them down. > admin launch of VMs doesn't create a stateless snapshot and > manipulates the VM itself. This raises some questions. I'd love to understand this better. He's asked me to cross this conversation onto the Users list now. 1. My understanding is that a Pool clones VMs on demand from a template. So how does the admin "launch" the template? I thought the only way to exercise a pool is from the User Portal. Is it sufficient to do that as Admin? I thought the persistence only came when launching a VM from the Admin Portal. 2. My understanding of "sealing" a system is that this depersonalizes it - e.g. removes hostname, prepares network for reinitialization, etc. And that the next time the system boots up it re-personalizes. So if one were to restart it, even as admin, this would reverse the sealing process, which would seem to make sealing in the first place pointless. What am I missing? At the moment I don't see the point of sealing a VM before putting it into the Pool (assuming you're using DHCP, anyway). What happens if you don't? Thanks, Bob P.S. I note the behavior of Fedora vs RHEL 6 is quite different in this regard. If you follow the "sealing" process on the Quick Start page for Fedora it seems to have no visible effect, but on RHEL 6 it puts you through a re-personalization dialog which is rather extensive (and again, not really suitable for VDI use).
