Hosted-Engine Resource Upgrade Method
by Steve Atkinson 21 Nov '14

21 Nov '14

I was wondering what the recommended method is for adding RAM/CPUs etc. to the VM that runs the hosted-engine. If I attempt this from the manager, the response is "Cannot Edit: This VM is not managed by the engine" and I don't readily see a way to make changes to the VMs config from outside of the engine. vdsClient does not show that VM as running either. Thanks -Steve A

Node upgrade issue
by yao xu 21 Nov '14

21 Nov '14

Hi everyone ! I am looking something about ovirt node upgrade . we are using a old version of ovirt node 3.1. Also I test ovirt node 3.5 . Somethings is puzzling me . 1, In ovirt node 3.1 , it seemed I can't upgrade ovirt node ,because of Hostvg's existence. In Hostvg , something like ssh keys are stored here, I know this is important . Is it possible to let the node inherit these things ? so that I can upgrade the node without remove things in hostvg . 2, I made a ovirt-node-iso 3.5 version myself . But when I try to install it , it fails because the issue of selinux . In shell mode , type "localectl" ,it shows this . after setenforce 0 , localectl will work well . -

The motivation for the semicolons was to eliminate the (albeit remote) chance of of this bridge name colliding with a previously-defined network. It was introduced two years ago http://gerrit.ovirt.org/9562 and it is a bit two entrenched by now. Modifying it to another string, while it is used by multiple VM in a distributed cluster of host is a painful hassle. It would be much more advisable for puppet to support all device names acceptable by Linux (anything but ':. \t\0', without adding its own limitations. I have a vague memory that Foreman encountered the same problem, and fixed it. Regards, Dan.

Migrate Ovirt to/from RHEV
by John Gardeniers 20 Nov '14

20 Nov '14

What is the procedure to use when migrating Ovirt to or from RHEV? I'm assuming of course that there's little difference for the two directions. Is it just a matter of detaching the storage domain(s), dumping the engine database and attaching/importing them into the other system? regards, John

How does one add multiple custom properties ? tried: engine-config -s CustomDeviceProperties='{type=interface;prop={vlan=^[a-zA-Z0-9_ ---]+$}}{type=interface;prop={bridge=^[a-zA-Z0-9_ ---]+$}}' but ended up with one call vlan and the other prop :) If can add vlan and bridge then should be able to use a vNIC profile for adding an interface directly to OVS using a custom hook.

You could just make a hook script that runs an after_network_setup hook that does the ovs-vsctl for you ;-) Here you can see the presentation I gave last February at devconf about extending with configurators and hooks. http://blog.antoni.me/devconf14/#/8/1 I linked directly to a before_network_setup hook sample, because it works just like the after_network_setup hook. Instead of logging to systemd, just add that if 'remove' is not in data and network == 'ovirtmgmt', it adds the network bridge to the vswitch with python's subprocess.call or subprocess.check_output. You can send it if you want me to take a look ;-) PS: It is possible to write the hooks in bash, c, perl, etc. But we only have the convenience read_json methods and such for python. If you wanted to, you could have a simple bash hook that just checked if there was an ovirtmgmt bridge and it would add it doing ovs-vsctl in the before_vdsm_start hooking point. That would have the drawback that changing the ovirtmgmt bridge with oVirt UI would leave it disconnected again. > > Thanks, Phil > > ----- Original Message ----- > From: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > To: "Phil Daws" <uxbod(a)splatnix.net> > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > Sent: Monday, 27 October, 2014 9:56:38 AM > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > ----- Original Message ----- > > From: "Phil Daws" <uxbod(a)splatnix.net> > > To: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > > Sent: Monday, October 27, 2014 10:37:18 AM > > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > That is what I tried but oVirt appears to overwrite the bridge information > > on > > boot :( Thanks, Phil > > But before rebooting, does it work as you intended?

Cumulative VM network usage
by Lior Vernia 20 Nov '14

20 Nov '14

Hello, The need to monitor cumulative VM network usage has come up several times in the past; while this should be handled as part of (https://bugzilla.redhat.com/show_bug.cgi?id=1063343) in the mean time I've written a small Python script that monitors those statistics, attached here. The script polls the engine via RESTful API periodically and dumps the up-to-date total usage into a file. The output is a multi-level map/dictionary in JSON format, where: * The top level keys are VM names. * Under each VM, the next level keys are vNIC names. * Under each vNIC, there are keys for total 'rx' (received) and 'tx' (transmitted), where the values are in Bytes. The script is built to run forever. It may be stopped at any time, but while it's not running VM network usage data will "be lost". When it's re-run, it'll go back to accumulating data on top of its previous data. A few disclaimers: * I haven't tested this with any edge cases (engine service dies, etc.). * Tested this with tens of VMs, not sure it'll work fine with hundreds. * The PERIOD_TIME (polling interval) should be set so that it matches both the engine's and vdsm's polling interval (see comments inside the script), otherwise data will be either lost or counted multiple times. >From 3.4 onwards, default configuration should be fine with 15 seconds. * The precision of traffic measurement on a NIC is 0.1% of the interface's speed over each PERIOD_TIME interval. For example, on a 1Gbps vNIC, when PERIOD_TIME = 15s, data will only be measured in 15Mb (~2MB) quanta. Specifically what this means is, that in this example, any traffic smaller than 2MB over a 15-second period would be negligible and wouldn't be recorded. Knock yourselves out :)

Power Management - but no LO?
by Daniel Helgenberger 20 Nov '14

20 Nov '14

Hello, I am toying an idea involving using oVirt's PM capabilities (esp. the cluster power_saving policy) in conjuration with some consumer grate hosts for raw compute applications. Now, these hosts do not have any lights out or BMC capabilities. However, they could be started with WOL packets. Is there a way how this can be done in oVirt? Shutting down hosts with ssh and starting them with WOL? Thanks! -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767

Gluster command[<UNKNOWN>] failed on server ovhost1
by Fumihide Tani 20 Nov '14

20 Nov '14

Please help! I'm hosting an oVirt3.5 Engine server (CentOS6.5) and oVirt3.5 Host servers (CentOS 7.0). Today, I have stopped all oVirt services (ovirt-engine and vdsmd) and updated oVirt3.5 Engine server and ovirt3.5 Host server by "yum update". While update, some new Gluster components were installed. After update, I tried to reboot ovirt3.5 Engine and Node servers, but oVirt is not working. Portal's Events shows that: - Status of host ovhost1 was set to NonOperational. - Gluster command[<UNKNOWN>] failed on server ovhost1. My oVirt servers and VMs are not operational now. How to resolve? Many thanks, Fumihide Tani

Re: [ovirt-users] separate ovirtmgmt from glusterfs traffic
by Juan Pablo Lorier 20 Nov '14

20 Nov '14

Hi, In my experience, having ovirt traffic on the same nic that gluster can make your platafrom unstable. I was using it for large file storage and gluster has so big traffic that ovirt got confused and started marking hosts as unavailable because of hi latency. I've opened an RFE over a year ago, but had no luck with the team to get it done. In the RFE I was asking to have a way in the UI to decide which nic to use for gluster other than the MGMT net that is the one ovirt lets you use. There's another way to do this and it's from outside ovirt. There you have to unregister and re register the bricks using gluster console commands. This way, when you register the bricks, you can specify the IP address of the spare NIC and then the traffic will not interfere with the mgmt. There's a step that I don't recall much, but ovirt is going to need to know that the bricks are no longer is the mgmt IP, maybe someone else in the list can help with this. I can tell you that if you search the list you'll see my posts about this and the replys of those who helped my back then. Regards,

Sizing the master storage domain
by Nicolas Ecarnot 19 Nov '14

19 Nov '14

Hi, I know Itamar explained that the notion of master storage domain will disappear in some releases. But now, with a 3.4 I'm installing, I was wondering : - on my other oVirt setups, I started with one big (iSCSI) LUN, which is the master, and stored as many VMs I could - when space came to miss, I added another LUN, the another... - when I have to do some maintenance (grow, disable, other...) on a LUN, I can move my VM disks amongst the normal storage domains. When Empty, I can switch them off, add others, and so on The only one I can not play with is the master one. I came to think that I had no benefice storing anything on the master storage domain, and use only the normal storage domains. And then, I came to think I had no reason to dedicate a huge LUN for the master. Ok, but according to you, what is the minimum reasonable size for a master storage domain? -- Nicolas Ecarnot

Gluster access tied to one node?
by Chris Adams 19 Nov '14

19 Nov '14

So this may be a dumb question, but here goes... I set up a replicated Gluster volume for VM disk image storage. I specified the path as node9:gluster1 (where node9 is one of the two nodes with a brick). However, when I shut down node9, the VM using that storage automatically gets paused. I thought the replicated storage was supposed to work even if one node was down. Is there some other way to specify the path (did I do that wrong)? -- Chris Adams <cma(a)cmadams.net>

Complete evalution of backup solutions
by Mario Giammarco 19 Nov '14

19 Nov '14

Hello, I am evaluating ovirt and considering backups. I have three solutions: 1) iscsi san that does snapshots 2) Glusterfs 3) ovirt api So I have these questions: - if I use 1) can I import a snapshot as different storage domain? - glusterfs snapshot implementation is ready? Can I do consistent backups of gluster bricks? - is there an opensource backup software that can do incremental backups using ovirt api? Thanks in advance for interest, Mario
