Re: [Users] tuned profile for Centos hosts -- new Bugzilla or Regression
I did not run into this problem at all ( neither on my cos6.4 nor on my 6.5 hosts ). The "virtual-host" profile was chosen automatically, installation of vdsm was literally as simple as adding the following lines in the %post section of my kickstart file: rpm -ivh http://ovirt.org/releases/ovirt-release-el.noarch.rpm rpm -ivh http://mirror.1000mbps.com/fedora-epel/6/i386/epel-release-6-8.noarch.rpm yum -y update epel-release yum -y install vdsm On Mon, Jan 6, 2014 at 11:09 PM, Ted Miller wrote: > I posted a script (a while back) to get oVirt running on Centos hosts. > > One of the items in it has to do with what "tuned" profile to use.

Re: [Users] Network profile lost after host edit
To test this further I setup another 3.3.2-1.el6 ovirt-engine. I'm not seeing the same problem on the new engine. I'm going to try and move all configuration/VM's etc from the problem ovirt-engine install to the new one to see if the problem re-appears. I'll let you know how it goes.

It does remind me of one bug though; could it be that pressing the "Show Advanced Options" is what triggers the strange behavior? What version of oVirt engine are you running? Both 3.3.1 and 3.3.2 should be quite stable as far as this dialog is concerned, so upgrading might be a good idea. As for workarounds, it sounds like a GUI issue so I don't think there's anything you can do apart from upgrading the engine.

Re: [Users] GlusterFS Distributed Replicate
Hi, I finally got around to running some tests on our environment, are you getting the same case where as when one host drops the VM ends up in a paused state and can't be migrated? With your case, you should be able to obtain full HA, quorum is just a protection for split brain. If you enable the migration policy to migrate all VMs, in theory the VMs from the crashed node I assume should migrate to the other node when it sees the node is offline. I was wondering if this may be because of the VM reads directly from the gluster storage server and there doesn't seem to be any fail over? Would a NFS solution with keepalived across the two servers fix this issue as the connection would be isolated to IP address rather than the single gluster node? I'm not too familiar with completely how the libgfapi protocol works. Could anyone else chime in? Cheers, Andrew.

Re: [Users] Deleting Storage Connection
As Itamar said, there is a nicer way to do it. In order to delete a connection, you can do it also via REST-API. You'll need a plugin for your browser (I'm using Rest client for Firefox). Go to storageconnection under api using 'GET': https://hostname:443/api/storageconnections Under that, you'll see your old ISO domain connection (by UUID), use DELETE, in order to remove it. Just remember, you'll be able to remove a connection only if it's not used by any domain. Hope it helped.

[Users] Experience with low cost NFS-Storage as VM-Storage?
Hi, I'd like to ask around if someone does run oVirt with NFS backed Storage provided by simple servers (no SAN or NAS) and what your experience is so far? In particular I'm interested what happens if there is a connection loss to the NFS-Volume. How does this affect running vms and the compute nodes they run on? I suspect they would first write their changes to RAM instead of virtual HDD. But once the RAM is full, does just the vm become unresponsive or does the whole compute node die? I couldn't test this yet myself, but my limited experience with NFS-Servers tells me, that they become unresponsive if they are under heavy load and I'd like to know how this affects the vms and computenode. Thanks! PS: Bonus question: Does someone utilize the NFS-Servers also as computenodes ? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

Re: [Users] Deleting Storage Connection
Hi, actually I think your description is far to shorthanded for everyone except for people who already know how to delete a storage connection and how to do it via REST. However there is a quite accurate wiki site with a more detailed explanation: http://www.ovirt.org/Features/Manage_Storage_Connections#Delete_connection_.28DELETE.29 But it didn't work when I tested it the last time in 3.1.x But it should work in 3.3.2.

Re: [Users] [QE] 3.4.0 Release tracker
Hi, I already wrote it in the BZ, but I'll duplicate here for faster feedback: I'm willing to implement this if I can get some guidance in my leisure time, if nobody else does this already. The BZ states "The limitation is fictitious, and there is no gain in maintaining it." and I strongly agree on this. I don't know the exact parts of the source which must be altered but I assume it's more or less just removing checks?

Re: [Users] Experience with low cost NFS-Storage as VM-Storage?
> Hi, > >I'd like to ask around if someone does run oVirt > with NFS backed Storage provided by simple servers (no SAN or NAS) > and what your experience is so far? We are running OVirt (still in test phase) on three self build equal Ubuntu NFS servers over Infiniband (50 Euros for a ConnectX card + 50 Euros a cable + 400 Euros a switch). Due to massive bandwidth the bottleneck are the SATA disks and the RAID controller. I fixed some info at http://www.ovirt.org/Infiniband Our soon to be replaced ESX infrastucture uses the same platform. > In particular I'm interested what happens if there is a connection > loss to the NFS-Volume. You can be sure that the applications in your VMs will get stuck. They usually flush their write caches in regular intervals. This is directly translated into a NFS write on the hypervisor. At least it should be configured that way otherwise you could loose data in case of a crash. E.g. VM thinks data is persisent, but it was only cached in the hypervisor RAM. > How does this affect running vms and the compute nodes they run on? The hypervisor has no problems at all (except you run a df command) and the VMs usually will continue their operation after NFS recovers. Nevertheless the are lot of timeout settings in the architecute stack that may stop a running application inside the VM. Expect do have a lot of manual cleanup after a NFS failure. > I suspect they would first write their changes to RAM instead of virtual HDD. > But once the RAM is full, does just the vm become unresponsive or > does the whole compute node die? That would be bad practice. See above. > I couldn't test this yet myself, but my limited experience with > NFS-Servers tells me, that they become unresponsive if they are under > heavy load and I'd like to know how this affects the vms and > computenode. Defining heavy load is basically some kind of I/O calculation. A simple example from our setup. - Each NFS server has a RAID6 consisting of 14 SATA disks (7.2K) - The top-loaded NFS server runs a minimum of 140 8K I/Os per second - Assuming a random pattern we speak of 140 Read-Modify-Write cycles - That translates to roughly to 6*140=840 I/Os per second. - The 14 SATA disks offer a maximum of 14*90=1260 I/Os per second - No wonder that the NFS server gives usually a 20% wait I/O usage. > Thanks! > PS: Bonus question: Does someone utilize the NFS-Servers also as > computenodes ? We spearated that stricly. Otherwise we would go with a Gluster FS. Markus P.S. We leave VMWare because live storage migration of OVirt VMs gives us the possibility to reduce the complexity on the storage side.

Re: [Users] Creation of preallocated disk with Gluster replication
Hello, Do you need more informations about this issue ? Do you think this problem is likely to show up in other cases ? I mean, is that an expected behaviour with my environment, or is it unexpected ? Is there a way to limit the bandwidth usage for creation of pre-allocated disk so that it doesn't impact production ?

Re: [Users] Migration Failed
Hi guys, Apologies for the late reply. The VM (Tux) was created about 2 years ago, it was converted from a physical machine using Clonezilla. It's been migrated a number of times in the past, only now when trying to move it off node03 is it giving this error. I've looked for any attached images/cd's and found none unfortunately. Thank you so much for your assistance so far. Regards. Neil Wilson.

Here is how it's done (more detailed): 1) Install Rest-Clien plugin: https://addons.mozilla.org/he/firefox/addon/restclient/ wouldn't using the cli be simpler? 2) Access your setup using the plugin: Use GET method in order to get the storage connections. Attaching screenshot(29) so you can see how it should look like. 3) After you get into the storage connection list, You need to find the relevant connection. In order to know which connection to delete, look for the connection path you need to delete. It's specified under the connection. For example: storage_connection href= "/api/storageconnections/c1b8fe9f-e85b-4146-9a29-227ae845eb6c" id="c1b8fe9f-e85b-4146-9a29-227ae845eb6c"> lion.qa.lab.tlv.redhat.com nfs /export/elad/elad16 The export path from the nfs server is: lion.qa.lab.tlv.redhat.com , /export/elad/elad16 Now that you know which connection to remove, use DELETE method and pass the connection you want to remove. It's done by copying the UUID of the connection from the Response box to the URL box. It should look like this: https://elad-rhevm3.qa.lab.tlv.redhat.com:443/api/storageconnections/d2d13260-9164-4311-bb27-f5a0e09981b7 Also, you'll have to specify the host which will perform the removal. It's done like this: Under the 'Request' box, add: host_name Last thing you'll have to do is to add a header: In the top of the screen you have 'Headers' option. Pick 'Custom Header' and specify: name: Content-Type value: application/xml Press SEND.

Sven, Elad was giving further information on a tool added in 3.3 version which allows an easy way of editing the db (without manual commands in db). Before that, he listed the tables needed to be cleaned in the db. Perhaps you mean that not everyone know what sql commands they need to run in order to clean the lines from the tables?

[Users] Bad volume specification
I have a couple ESXi Win 7 images on VMDKs that I converted to raw using
qemu-img convert.
Under ovirt 3.3.1 I then used a procedure posted here previously where
you create a VM, add a disk, then copy over the converted image onto the
oVirt created image and away you go.
I did this twice under oVirt 3.3.1 and it worked great.
Now I have built a new oVirt 3.3.2 system and tried the same thing, and
I get the error:
VM win7-01 is down. Exit message: Bad volume specification {'index': 0,
'iface': 'virtio', 'reqsize': '0', 'format': 'raw', 'bootOrder': '1',

The original oVirt 3.3.1 system that has now been upgraded to 3.3.2
still boots this same disk image just fine.
I'm guessing it's upset because apparentsize and truesize are different?
Why did 3.3.1 seem not to care but 3.3.2 does now?
Any way I can true these up? I've tried a few things with qemu-img but
haven't gotten the magic right yet.

No quick answer pops to mind. Could you share your vdsm.log from the
vmCreate line up until the error you have quoted?

[Users] Need to recreate public RSA key on node
Hi, I inadvertently overwrote my root authorized_keys file on my host/node (copied instead of appended :( ), so I need to find the proper public RSA key to put back there for ovirt-engine. But I can't seem to find the private (or public) key on the Engine. There is no actual account "ovirt-engine" on the Engine. Where does this key come from? Any other suggestions on an easy way to recreate the file? This is my only node, and it hosts my Primary Data Domain, so I don't think I can easily remove/re-add it. My node was up at the time, and surprisingly it remains up and operational at least for now. What is the remote root ovirt-engine login used for? -Bob ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Creation of preallocated disk with Gluster replication
Grégoire- I think this is expected behavior. Well, at least the high glusterfsd CPU use during disk creation, anyway. I tried creating a 10 G disk on my test environment and observed similar high CPU usage by glusterfsd. Did the creation on the i5 system, it showed 95%-105% cpu for glusterfsd during creation, with the core2 system running ~35-65% glusterfsd utilization during the creation. Minor disk wait was observed on both systems, < 10% peak and generally < 5%. I imagine my ZFS cached backends helped a lot here. Took about 3 minutes, roughly what I’d expect for the i5’s disk system. Network usage was about 45% of the 1G link. No errors or messages logged to /var/log/messages. Depending on what your test setup looks like, I’d check my network for packet loss or errors first. Then look at my storage setup and test pure throughput on the disks to see what you’ve got, maybe see what else is running. Did you use an NFS cluster or a PosixFS cluster for this?

Bought some cheap SSDs and just grabbed systems and platters I had around for it. Testbedding and getting some experience with the self hosted engine, since I’d like to move to it once it’s released. Also looking forward to testing native gluster on this setup. I have a production ovirt cluster with a linux zfs based NFS storage server, the backend has been very stable since I got rid of Nextenta and went to linux. Sounds odd, I know, but couldn’t get good support for a community nextenta server I inherited. I was having driver level box lockup issues with openSolaris that I couldn’t resolve.

[Users] no VM network connection
Hi all, Need some pointers here. I created one VM successfully with network connection. New VMs and clone can't seem to get network connections. I have ovirt 3.3.2-1.el6 on CentOS6.5. Two virtualization nodes are on 6.5 with GlusterFS. Both nodes have bond0 on management subnet and bond1 on subnet1. bond0 has an IP assigned and bond1 has no IP assigned (just link up) I created a VM with two NICs attached to two the logical networks. This VM1 works fine with both network connections. This VM can be started on either node fine with network connections. When I tried to build a new VM or build one from the template of VM1, I can't seem to get another network connection working on these new VMs. Yes, they have logical network attached to them.

Hi Blaster,
Have you added the second disk after upgrading oVirt version?
An explicit address setting mechanism has been introduced recently,
which might cause such problems between minor versions.
Can you please attach the full engine/vdsm logs?

[Users] SSD Caching
[20:42] is anybody out there using a good RAM+SSD caching system ahead of gluster storage? [20:42] sorry if that came through twice [20:44] im thinking about making the SSD one giant swap file then creating a very large ramdisk in virtual memory and using that as a block level cache for parts and pieces of virtual machine disk images [20:44] then i think the memory managers would inherently play the role of storage tiering ie: keeping the hottest data in memory and the coldest data on swap [20:45] everything i have seen today has been setup as "consumer" ===> network > SSD cache > real disks [20:45] but i'd like to actually do "consumer" ===> RAM+SSD cache ===> network ===> real disks [20:46] i realize doing a virtual memory disk means the cache will be cleared on every reboot, and I'm ok with that [20:47] i know this can be done with NFS and cachefilesd(fscache), but how could something be integrated into the native gluster clients? [20:47] i'd prefer not to have to access gluster via NFS [20:49] any feedback from this room is greatly appreciated, getting someone started to build managed HA cloud hosting ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Hi, It may be related to the IPv6 bounce we got from a spam filtering service recently.

Will keep everyone posted, we'll see if it makes a difference. Thanks, Dave.

Hi Blaster,
Have you added the second disk after upgrading oVirt version?
An explicit address setting mechanism has been introduced recently,
which might cause such problems between minor versions.
Can you please attach the full engine/vdsm logs?
Thanks,

Subject: [Users] virt-io SCSI duplicate disk ID
So twice now under oVirt 3.3.2 I have added 2 virtio-scsi devices to a single
virtual host.
After doing so, the VM would fail to boot due to duplicate disk ID. The first
time I thought it a fluke, second time’s a bug?
Fortunately they were empty data disks and I was able to get around the
problem by deleting one and recreating it.

With NFS you set up the network with LACP and let that load-balance for you (and you should probably do that with iSCSI as well but you don´t strictly have to). I think it has to do with a chance of trying to go beyond the capacity of 1 network interface at the same time, from one Host (higher bandwidth) that makes people try iSCSI instead of plain NFS. I have tried that but was never able to achieve that effect, so in our situation, there´s no difference. In comparing them both in benchmarks, there was no performance difference at all, at least for our storage systems that are based on FreeBSD. /K ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Experience with low cost NFS-Storage as VM-Storage?
There's are already enaugh articles on the web about NFS problems related locking, latency, etc Eh stacking a protocol onto another to fix problem and then maybe one more to glue them together. Google for the suse PDF " why NFS sucks", I don't agree with the whole sheet.. NFS got his place,too. But not as production filer for VM.

Multipathing (and the load-balancing it brings) is what really separates iSCSI from NFS. What I´d be interested in knowing is at what breaking-point, not having multipathing becomes an issue. I mean, we might not have such a big VM-park, about 300-400 VMs. But so far running without multipathing using good ole' NFS and no performance issues this far. Would be good to know beforehand if we´re headed for a wall of some sorts, and about "when" we´ll hit it... /K > > On Jan 9, 2014 8:30 AM, "Karli Sjöberg" wrote: > On Thu, 2014-01-09 at 07:10 +, Markus Stockhausen wrote: > > > Von: users-boun...@ovirt.org [users-boun...@ovirt.org]" im > Auftrag von "squadra [squa...@gmail.com] > > > Gesendet: Mittwoch, 8.
