oVirt 4.0 wishlist: oVirt Self Hosted Engine Setup
by Giuseppe Ragusa 29 Nov '15

29 Nov '15

Hi all, I go on with my wishlist, derived from both solitary mumblings and community talks at the the first Italian oVirt Meetup. I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...) I've sent separate wishlist messages for oVirt Node, oVirt Engine and VDSM. oVirt Self Hosted Engine Setup: *) allow virtual hardware customizations for locally-created Engine vm, specifically: allow to add an arbitrary number of NICs (asking for MAC address and local bridge to connect to) and maybe also an arbitrary number of disks (asking for size) as these seem to be the only/most_useful items missing; maybe the prebuilt appliance image too may be inspected by setup to detect a customized one and connect any further NICs to custom local bridges (which the user should be asked for) Regards, Giuseppe

3.6: updating a template in a vm pool causes removal of soundcard and memory ballon device
by Cristian Mammoli 29 Nov '15

29 Nov '15

Hi, when I change template version in a vmpool the souncard and balloon device get cleared, even if the new template has sound and ballon enabled. After that the checkbox are greyed out and cannot be enabled without destroying and recreating the pool... How to reproduce: Create a template with soundcard and memory ballon device Create a pool from the above template VMs and the pool itself have sound and balloon device Create a new Template as version 2 of the original one Check that sound and balloon are enabled in the template Reconfigure the pool to use version 2 of the template VMs and the pool itself have sound and balloon *unchecked* and cannot be enabled anymore

vdsm using 100% CPU, rapidly filling logs with _handle_event messages
by Robert Story 27 Nov '15

27 Nov '15

--Sig_/War1DBdDuKL/JOwM_gN0y1g Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable I'm running oVirt 3.5.x with a hosted engine. This morning I noticed that 2 of my 5 hosts were showing 99-100% cpu usage. Logging in to them, vdsmd seemed to be the culprit, and it was filling the log file with these messages: VM Channels Listener::DEBUG::2015-11-12 08:09:26,292::vmchannels::59::vds::(_handle_event) Received 00000011. On fd= removed by epoll. VM Channels Listener::INFO::2015-11-12 08:09:26,293::vmc= hannels::54::vds::(_handle_event) Received 00000011 on fileno 119 VM Channels Listener::DEBUG::2015-11-12 08:09:26,293::vmchannels::59::vds::= (_handle_event) Received 00000011.

VM Channels Listener::INFO::2015-11-12 08:09:26,294::vmchannels::54::vds::(= _handle_event) Received 00000011 on fileno 119 VM Channels Listener::DEBUG::2015-11-12 08:09:26,294::vmchannels::59::vds::= (_handle_event) Received 00000011. On fd removed by epoll. I googled to see how to change the debug level to turn of DEBUG messages for vdsm, which referred me to libvirtd.conf, but the debug level there was not set, which should have meant a log level of 3 (warnings and errors), so I'm not sure why the log was filling up with DEBUG/INFO messages. I restarted vdsmd, which resulted in those nodes being marked as 'disconnected', but they did eventually recover and loads went back to normal. This may or may not be related to the fact that the 3 hosts where this did not happen can't seem to keep their ha brokers up. I'll be starting a new thread on that shortly.

Hi All, One of our users on ovirt who always was able to login with the AD account, now all of a sudden can't login anymore...

Controlling UI table column visibility and position
by Vojtech Szocs 26 Nov '15

26 Nov '15

Dear developers and users, it's now possible to tweak table column visibility and position through header context menu in WebAdmin's main & sub tabs [1,2]. [1] https://gerrit.ovirt.org/#/c/43401/ [2] https://gerrit.ovirt.org/#/c/47542/ This allows you to turn "unwanted" columns off and re-arrange those which are visible to match your personal preference. Screenshot of customizing VM main tab: https://imgur.com/5dfh8QA There's also RFE [3] to persist (remember) such column settings in the browser, similar to persisting other client-side options. [3] https://bugzilla.redhat.com/1285456 Regards, Vojtech

Mix local and shared storage on ovirt3.6 rc?
by Liam Curtis 26 Nov '15

26 Nov '15

Hello all, Loving ovirt...Have reinstalled many a time trying to understand and thought I had this working, though now that everything operating properly it seems this functionality is not possible. I am running hosted engine over glusterfs and would also like to use some of the other bricks I have set up on the gluster host, but when I try to create a new gluster cluster in data center, I get error message: Failed to connect host <myhost> to Storage Pool Default. I dont want to use just gluster shared storage. Any way to work around this?

VM Network activity on RHEV-M UI
by Marc Seward 26 Nov '15

26 Nov '15

I'm generating network activity on a RHEV 3.5 VM using iperf.The VM acts as an iperf client.On the client,iperf reports that data has been successfully sent to iperf server.The iperf server also shows that it's successfully receiving data from the iperf client.But,network is at 0% on the RHEV-M UI.The client and server are on different private networks. On the same VM,when I generate network activity by fetching a file from a public network using wget,the network column correctly shows activity on the RHEV-M UI for the VM. Could someone help me understand why I am unable to see network activity on the RHEV-M UI when iperf is used? Appreciate your help.TIA.

Hi, I'm trying to add virtual NICs for a new VM.

You are right: I was bothering you with this setup wishlist item *mainly* because further Engine vm modification was impossible/awkward/difficult before 3.6.1 Nonetheless I have seen many cases in which at least a second NIC would be absolutely needed to complete the Engine installation: it is a well known best practice to keep the management network (maybe conflated with the IPMI network in smaller cases) completely isolated from other services and to allow only limited access to/from it, and that network would be the ovirtmgmt-bridge-connected network (the only one available to the Engine, as of now); now think of a kickstart-based Engine OS installation/update from a local repository/mirror which would be reachable on a different network only (further access to the User/Administration Web portal could have similar needs but could be more easily covered by successive Engine vm modifications) The "additional disks" part was (maybe "artificially") added by me out of fantasy, but I know of at least one enterprise customer that by policy mandates separate disks for OS and data (mainly on FC LUNs, to be honest, but FC is supported by hosted Engine now, isn't it?) I absolutely don't know how the setup code is structured (and the recent logical "duplication" between mixins.py and vm.conf.in scares me a bit, actually ;), but I naively hope that changing the two single hardcoded nic/hdd questions into two loops of minimum 1 iteration (with a corresponding generalization of related otopi parameters) should not increase the complexity too much (and could be an excuse to rationalize/unify it further). Obviously I could stand instantly corrected by anyone who really knows the code, but in exchange I would gain for free some interesting pointers/insights into the setup code/structure ;) >> Regards, >> Giuseppe >> _______________________________________________ >> Users mailing list >> Users(a)ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users

oVirt Node roadmap
by Fabian Deutsch 25 Nov '15

25 Nov '15

Hey, in the last few months the Node team spent a lot of efforts in stabilizing Node by closing tons of bugs, rebasing Node onto CentOS 7.2, and in addition adding features like Hosted-Engine - to get Node in shape for the recently released oVirt 3.6.0. But we were also seeing how Node is showing it's age. It becomes more and more challenging to solve bugs and implement features in Node's current architecture. To address these problems, and let Node adjust better to new changes, a few months ago we started to look at how we can change Node, to make it easier to develop, test, and use. This comparison [1] shows a brief summary of our investigations. We especially looked at Atomic and containers [2]. At the bottom line both of them provided us an architecture which would help us to achieve something like 70% of what we need. But during early trials we quickly ran into issues which we experience in similar ways with today's Node. Finally we settled an approach - the idea was around since right from the beginning - which aligns very well with existing technologies which we already use in the oVirt and Fedora/CentOS scope. The new Node will be using anaconda for installation, LVM for upgrades and rollbacks, and Cockpit [3] for administration. The future design is taking care that packages don't need to take special care to work on Node - which was a major obstacle in the past. Node will rather behave (mostly) like a regular host - but with the advantages of an easy & ready to use image, image based delivery and a robust rollback. The current design principles and links to some additional resources are in the wiki [4]. Stay tuned, we are just getting started. On behalf of the Node Team fabian -- [1] http://www.ovirt.org/Node/Specs#Comparison:_Possible_Implementations [2] http://www.projectatomic.io/ ~ http://docker.com/ [3] http://cockpit-project.org/ [4] http://www.ovirt.org/Node/4.0

Problem with Adding Pre-Configured Domain
by Roger Meier 25 Nov '15

25 Nov '15

This is a multi-part message in MIME format. --------------050208060806020800020208 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi All, I don't know if this is a Bug or an error on my side. At the moment, i have a oVirt 3.6 installation with two Nodes and Two Storage Server, which are configured themselfs als master/slave (solaris zfs snapshot copy from master to slave all 2 hours) Now i try to do some tests for some failure use cases like, master storage isn't available anymore or one of the virtual machines must be restored from the snapshot. Because the data n the slave is a snapshot copy, all data which are on the Data Domain NFS Storage, are also on the slave NFS Storage. I tried it to add over WebUI over the option "Import Domain" (Import Pre-Configured Domain) with both Domain Functions (Data and Export) but nothing happens, expect some errors in the vdsm.log Logfile. Something like this Thread-253746::ERROR::2015-11-24 11:44:41,758::hsm::2549::Storage.HSM::(disconnectStorageServer) Could not disconnect from storageServer Traceback (most recent call last): File "/usr/share/vdsm/storage/hsm.py", line 2545, in disconnectStorageServer conObj.disconnect() File "/usr/share/vdsm/storage/storageServer.py", line 425, in disconnect return self._mountCon.disconnect() File "/usr/share/vdsm/storage/storageServer.py", line 254, in disconnect self._mount.umount(True, True) File "/usr/share/vdsm/storage/mount.py", line 256, in umount return self._runcmd(cmd, timeout) File "/usr/share/vdsm/storage/mount.py", line 241, in _runcmd raise MountError(rc, ";".join((out, err))) MountError: (32, ';umount: /rhev/data-center/mnt/192.168.1.13:_oi-srv2-sasData1_oi-srv1-sasData1_nfsshare1: mountpoint not found\n') I checked with nfs-check.py if all permissions are ok, the tool say this: Konsole output [root@lin-ovirt1 contrib]# python ./nfs-check.py 192.168.1.13:/oi-srv2-sasData1/oi-srv1-sasData1/nfsshare1 Current hostname: lin-ovirt1 - IP addr 192.168.1.14 Trying to /bin/mount -t nfs 192.168.1.13:/oi-srv2-sasData1/oi-srv1-sasData1/nfsshare1...

Move cluster between datacenters
by Dael Maselli 24 Nov '15

24 Nov '15

Hello, I have an environment with two data centers with some clusters in each one. Each cluster has one or more dedicated FC storage domains. We have some management problem because adding storage to one cluster means to add it to all nodes of all clusters in the same data center, by the way I found this a little overkill and I think it should be managed like networks. Anyway, to resolve out problems we would like to create a new datacenter and move a cluster from old data center to the new one, obviously with it's own storage domain. Is there a way to do this without export/import all vms? Thank you. Regards, Dael Maselli. -- ___________________________________________________________________ Dael Maselli --- INFN-LNF Computing Service -- +39.06.9403.2214 ___________________________________________________________________ * http://www.lnf.infn.it/~dmaselli/ * ___________________________________________________________________ Democracy is two wolves and a lamb voting on what to have for lunch ___________________________________________________________________

oVirt 4.0 wishlist: oVirt Node
by Giuseppe Ragusa 24 Nov '15

24 Nov '15

Hi all, I'm trying to organize my wishes/hopes for oVirt 4.0 These items derive from both solitary mumblings and community talks at the the first Italian oVirt Meetup. I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...) Since I have related interests/wishes also for Engine and VDSM, I'll send a separate message for each one. Let's start from the oVirt Node: *) oVirt Node complete convergence with Atomic Host: start from Project Atomic tools and define an ISO-installable Atomic Host variant [1] to include gluster, qemu, libvirt, vdsm and all the packages/configurations that an oVirt Node would need (remove unneeded parts) *) add Samba, CTDB and Ganesha to oVirt Node to allow it to be used as a full storage appliance (specifically, I'm thinking of the GlusterFS integration); there are related wishlist items on configuring/managing Samba/CTDB/Ganesha on the Engine and on VDSM *) add oVirt Node ability to host containers (independent of the above mentioned convergence with Atomic); note that Atomic Host has Docker/Kubernetes, but libvirt already has a LXC driver [2] and the Engine could benefit from some added smartness in managing groups of guests etc. in the vm case too; there are related wishlist items on configuring/managing containers on the Engine and on VDSM *) add Open vSwitch direct support (not Neutron-mediated); there are related wishlist items on configuring/managing Open vSwitch on the Engine and on VDSM *) add DRBD9 as a supported Storage Domain type, maybe for HC and HE too; there are related wishlist items on configuring/managing DRBD9 on the Engine and on VDSM *) add oVirt Node ability to fully perform as a stand-alone hypervisor: I hear that Cockpit is coming, so why not Kimchi too? ;) Regards, Giuseppe [1] product.json, I suppose, but I'm starting to learn Atomic now... [2] barring a pending deprecation in RHEL7, but I suppose that a community/Centos-Virt-SIG libvirt build could restore it and maybe RedHat too could support it on a special libvirt build for RHEV (just to remove those support costs from the base RHEL OS offering)
