Re: [ovirt-users] Guest PXE boot with 2 NICs : MAC order
Indeed, if you're using oVirt 3.4 and up, and you supply all the NICs whenever you create the VM (not afterwards - as part of the new VM dialog), the NICs should receive MAC addresses according to their ordering by names, e.g. nic1 will always get a lower MAC address than nic2. For a newly-created VM this should guarantee that nic1 will indeed end up the first NIC inside the guest OS and be used by PXE. If this is something you do a lot, then I'd suggest creating a new template as such and create VMs from that.

Re: [ovirt-users] oVirt management network
The situation you got to (where there are ovirtmgmt bridges over both bond0 directly and over the bond0.231 VLAN device), likely via manual intervention, is indeed inconsistent from oVirt's perspective. You should be able to SSH into the host and run something like brctl delif ovirtmgmt bond0, then refresh capabilities on the webadmin console and get to a situation where ovirtmgmt is configured only on top of the VLAN device. Succeeding networking operations on the host should then work as expected... On 31/03/15 14:03, Bojan Popovic wrote: Of course. Here it is: net As you can see on the lower part of the screenshot, ovirtmgmt is on top of the bond0.231 interface and on top of bond0 also.

Since you have connectivity to the host, we can tell that you have un-tagged traffic to the host. In most (sane) cases, the IP address on the untagged network is different from the vlan'ed one. To use the latter, you'd need to remove the host from the cluster, and add it back with its second address. Did you define ovirtmgmt as a vlan-tagged network?

Re: [ovirt-users] mixing tagged and untagged vlans on a same interface
What Martin said is correct, let me just add that originally this limitation was put in place because in older kernels the bridge for the untagged network could see tagged traffic over the same physical interface, which was a security loophole (as a VM using the untagged bridge could sniff all the traffic on the physical interface).

Right now that's a 'configurable option' inside network interface settings on the VM in the manager (ie, plugged, not plugged, and link state up /down) If I'm not mistaken, once you have direct access to the PCI device you'll be able to query for its actual state using e.g. ethtool.

This does work well on linuxhost1, i.e. one can ping and surf outbound and ssh / tigervnc in via 192.168.12.30. I did name the major bridge ovirtmgmt after endless trying. Of course, linuxhost1 and the engine ovirt1 can ping each other with no difficulties whatsoever. - In the web interface of the hosted engine, however (Hosted Engine Network.pdf, page 3) the required network ovirtmgmt is initially not connected to bond0 (while it is in reality connected, as ifconfig shows). When dragging ovirtmtgt to the arrow pointing to bond0, it does not work. The error message is Bad bond name, it must begin with the prefix 'bond' followed by a number. This is easy to understand, as bond0 is a combination of bond and the number zero. Please point me to the right direction.

I meant the case of, say, Engine going down while VMs continue to chug bandwidth. One of these VMs dies (say, the user shuts it down). When Engine wakes up, it would find the VM in Down state. I wonder if Vdsm should keep the last tx/rx used by this VM so Engine can collect it, and charge the VM properly. A similar case can occur if a host is rebooted while Engine was away. But there I see no way to keep trace of the unaccounted-for badwidth. This would require a double failure - first the engine losing connectivity to the host, then at a later point the host/VM shuts down. If the engine loses connectivity but the host/VMs remain operational, then as soon as the engine regains connectivity it'll be brought up to speed (traffic could be missed if the RX/TX counters on the host/VMs exactly wrapped around during that period, which is highly unlikely). If the host/VMs go down without the engine losing connectivity, the engine should continue to accumulate statistics correctly. So the problem isn't grave (though I'll document those cases in the feature page), and the solution won't be trivial. Would you really want vdsm to track this data?

Re: [ovirt-users] change network MTU settings without taking all the VMs down?
Hi Darrell! There's currently no clean way to do this - we'll be looking to fix this in 3.6 (https://bugzilla.redhat.com/show_bug.cgi?id=1055454). You haven't mentioned which version of oVirt you're running - if it's 3.4 or lower, I think it would suffice to change ifcfg files on your hypervisors and restart the network service. The network will then appear as out-of-sync in the GUI, but should be fully functional with MTU 1500. You'd also want the network configuration to be saved in case of future rollbacks - Dan, how would that be done? If you're running 3.5, I think you need to run some vdsm shell commands on the hypervisor as we've added an abstraction layer for configuration persistence above ifcfg files - again I'll ask Dan to chime in. As for getting the engine network configuration to MTU 1500 (for future hypervisor configuration and for networks to not appear as out-of-sync on existing ones) without taking down all the VMs (or hot-unplugging NICs) at one point - I don't think there's currently a way other than hacking the DB... Just leaving the network out-of-sync on the hosts could result in inconveniences later on when configuring host networking. Is it worth the trouble of getting MTU 1500 instead of 1448? I presume the difference in performance would be negligible. Or are you experiencing incoming frames being dropped due to having 1500 bytes instead of 1448?... Either way, as you mentioned taking down the VMs can be a last resort, or wait for 3.6 where it should be simpler :) Yours, Lior.

In the Add Bricks dialog, it seems like the IP Address field is a list box - I presume the items contained there are all IP addresses configured on the host's interfaces. 1. a. May I suggest that this contain network names instead of IP addresses? Would be easier for users to think about things (they surely remember the meaning of network names, not necessarily of IP addresses). 1. b. If I correctly understood the mock-up, then configuring a Storage Network role only affects the default entry chosen in the list box. Is it really worth the trouble of implementing this added role? It's quite different than display/migration roles, which are used to determine what IP address to use at a later time (i.e. not when configuring the host), when a VM is run/migrated in the cluster. If not for Storage network role, how would we default which network to use. In fact, we are planning to remove the drop down to choose network from the Add Brick UI, to avoid confusion and just use the network with this role, if available - otherwise use the host address. (host_address in vds_static) If the list box goes, then yeah, somehow you'll have to mark the network used for gluster traffic, so a role would be good. However, if you keep the list box, any order would be fine (maybe alphabetic with the management network as default?). Will update page accordingly 1. c. A word of warning: sometimes a host interface's IP address is missing in the engine - this usually happens when they're configured for the first time with DHCP, and the setup networks command returns before an IP address is allocated (this can later be resolved by refreshing host capabilities, there's a button for that). So when displaying items in the list box, you should really check that an IP address exists for each network. 2.

I think moving networks or changing their IP addresses via Setup Networks should be blocked if they're used by gluster bricks. In the suggested feature, there is no real storage role. The storage role title means only default value for glusterfs IP. For example, once a brick was created, nothing protects the admin from accidently removing the storage network, or changing its IP address. Another proof that this is not a real role, is that it affects only GUI: I am guessing that REST API would not make use of it at all. (maybe I'm wrong; for sure, REST must be defined in the feature page) REST API that lists the available networks (with IP addresses) would be used to select the network and pass to the create gluster volume API I'll update the feature page with the REST API changes as well. If REST allows to choose the network used for gluster traffic, then I think so should the GUI - I would not drop the list box from the design in that case. Maybe that's the behavior we want. But alternatively, Engine can enforce a stronger linkage between the brick to the network that it uses. When adding a brick, the dialog would list available networks instead of the specific IP. As long as the brick is being used, the admin would be blocked/warned against deleting the network. Is there a way to block against changing IP address used by a network? Yes, this should be implemented at least in the canDoAction() method of SetupNetworksCommand (most of it is done in the SetupNetworksHelper class). And perhaps this should be blocked in the GUI as well. Note that by the time 3.6 is released, the REST (and probably GUI) are supposed to work with a different backend command that is currently being implemented - so maybe you'll need to modify that instead, or on top of the changes in SetupNetworksHelper. I'm missing a discussion regarding the upgrade path. If we would opt to requiring a single storage role network in a cluster, in an upgraded cluster the management network should take this role. There would not be any change to existing volumes on upgrade, as bricks have already been added. Users can use the Edit brick option to update the network to be used, if required as mentioned in Change network used by brick I suspect Dan referred to the upgrade path of the engine itself - if you add a new Gluster Network boolean column to the DB, it will initially be null for all current networks. You'd likely need to write an upgrade script to assign the role by default to the existing management networks in each cluster. 3. Adding to 2, perhaps using DNS names is a more valid approach? 4. You're using the terminology role, but it might be confusing, as we have roles with regards to permissions. Consider changing storage usage and not storage role in the feature page. Well, we've already been using this terminology for a while now concerning display/migration roles for networks... That's probably the terminology to use.

Re: [ovirt-users] [Feature review] Select network to be used for glusterfs
Hi Sahina! :) Cool feature, and I think long-awaited by many users. I have a few comments: 1. In the Add Bricks dialog, it seems like the IP Address field is a list box - I presume the items contained there are all IP addresses configured on the host's interfaces. 1. a. May I suggest that this contain network names instead of IP addresses? Would be easier for users to think about things (they surely remember the meaning of network names, not necessarily of IP addresses). 1. b. If I correctly understood the mock-up, then configuring a Storage Network role only affects the default entry chosen in the list box. Is it really worth the trouble of implementing this added role? It's quite different than display/migration roles, which are used to determine what IP address to use at a later time (i.e. not when configuring the host), when a VM is run/migrated in the cluster. 1. c. A word of warning: sometimes a host interface's IP address is missing in the engine - this usually happens when they're configured for the first time with DHCP, and the setup networks command returns before an IP address is allocated (this can later be resolved by refreshing host capabilities, there's a button for that). So when displaying items in the list box, you should really check that an IP address exists for each network. 2. Storage Network: if you intend to keep this role in the feature (I don't think it adds a lot of functionality, see article 1b), it might be better to call it Gluster Network - otherwise people using virt mode might think this network is gonna be used to communicate with other types of storage domains.

Re: [ovirt-users] Unable to reinstall hosts after network removal.
I think pressing the Refresh Capabilities button at the hosts main tab might help after you remove the IB interface - this forces the engine to update its DB state to what's reported by the hypervisor.

Or have you removed those networks from the host directly (where you should used the: 1. virsh net-destroy 'the-network-name' 2. virsh net-undefine 'the-network-name' ) can you report the output of 'virsh -r net-list' ? Then after removing network from data center the hosts went to unusable. What was the host's status prior to removing its networks ? Was it up ? Every time after reinstall the host claims that the network is not configured, but it s already removed from network tab in DC. What is the missing network name ? Is it 'ovirtmgmt' ? Where from it gets the old configuration? the old interfaces also restored every time on the reinstalled hosts. The hosts via vdsm reports their network configuration via the 'getCapabilities' verb of vdsm. You can try running it on the host: vdsClient -s 0 getVdsCaps and examine the nics / neworks / bridges / vlans / bonds elements. Which DB table is in charge of dc-networks? The retrieved information from vdsm is reported to 'vds_interace' table. The dc networks are stored in 'networks' table and networks attached to clusters are stored in network_cluster table. I wouldn't recommend on deleting entries from the tables directly.

Re: [ovirt-users] EXTNET Hook and Libvirtd Default Network Setup
Hi Andrew, In the medium term I think that might be easier and more scalable - oVirt should allow you to not have to deal with libvirt plumbing. Re-reading your original e-mail, I only now understand that you're using the default network to setup NAT, and that you weren't adding iptables rules on your own. If you do prefer to go with that, I have very little knowledge of libvirt's NAT. Maybe others on the list know more... Yours, Lior.

Hello everyone!
I just finished setting up our new demo Ovirt implementation, but am

The host {hostname} did not satisfy internal filter Network because
network(s) are missing.
This reminds me of issues with missing boot protocol for the display
network on hosts (there's a bug on improving the error message for
that). Does ovirtmgmt have a boot protocol and IP address configured on
the hosts?
This is trying to launch vm with the Cirros image from the OVirt glance
repository. This is confusing, because we only have one network defined
(the ovirtmgmt network), and each of our 4 nodes shows it attached and
indicated as functional.
Our nodes are all CentOS 6.6 installations, with the ovirtmgmt bridge
bound to eth2. If I go to Networks/ovirtmgmt under my datacenter, and
click on the Networks tab at the top, select the ovirtmgmt network, and
Hosts tab at the bottom, it shows that ovirtmgmt network is up on all 4
nodes. Even if I tell the VM to not attach itself to any networks at
all, the machine fails to start with the same error. Have done a lot of
google searching to no avail.
We're also worried we did not get our gluster storage network set up
right. We added the Storage Domain as type Data (Master)/GlusterFS, but
it looks like Ovirt is using Fuse rather than the new libgfapi
functionality - since we can see the gluster mounted
/rhev/data-center/mnt/glusterSD/ with fuse.glusterfs, which would
indicate we are not using the native Gluster integration. However, the
latest info I can find seems to indicate that the gluster integration
should be working in latest CentOS builds.
Thanks for any help anyone can give me! The boss wants this demo sooner
rather than later!

Hi Harald, Could you perhaps refine your question? Also, what do you mean by console user - are you referring to a VM? The hardware of a host is the principal factor in determining the best computing power of a VM, but of course there'll always be some overhead (i.e. it'll never be equal to the host's computing power). If you elaborate we could give you a better answer. Yours, Lior.

Hi Tibor, On 13/11/14 13:41, Demeter Tibor wrote: Hi, I have a 3 node gluster based cluster. There are 3x3 Nic with bonding. Sometimes the management is very slow because high gluster traffic. Is it possible to separate ovirtmgmt network from glusterfs traffic? I have only one interface (ovirtmgmt) for all of services (migration, etc). I just wondering I will make three VLANs for these services and use the QoS function. But how can specify glusterfs for use an other vlan for gluster traffic an a other one for management? This generally sounds like a good plan, but note that QoS on the host-level will only become available in oVirt 3.6 (it might become available soon on master, if you're feeling lucky...). VM-level QoS (available since 3.3) won't help you with administrative traffic (i.e. traffic that isn't going into / coming out of the VMs themselves). Also, I have more questions about this: - If I specify a VLAN on ovirtmgmt, then what happend on nodes? I'm afraid the nodes will lost the connection with each other nodes. If the switch allows this VLAN to reach all hosts, there shouldn't be a problem; since oVirt 3.4 the VLAN tagging should propagate to all active hosts. However, see my comment below concerning VM network. - Is it possible on a live system? What will happen with the mounted glustefs based datastores? I'm not knowledgeable about gluster specifics, but let's see if I can help. What's the current situation with the gluster network, is it already VLAN-tagged? If it is and you're not moving it to another interface on the hosts, I *think* things should be fine. - What does vm network mean on ovirtmgmt interface? Can I use this for seperate network traffic? This means that a bridge is created for this network on hosts. If VMs don't use this network (i.e. virtual interfaces are assigned profiles of ovirtmgmt), you can make it non-VM (with no VLAN tagging) and have it assigned to the same host interface as VLAN-tagged networks (I would say this is less risky than VLAN-tagging ovirtmgmt). My plan is - vlan.101 ovirtmgmt - vlan 102 glusterfs - vlan 103 migration - vlan 104 display What is the recommended procedure of this?

But how can specify glusterfs for use an other vlan for gluster traffic an a other one for management? This generally sounds like a good plan, but note that QoS on the host-level will only become available in oVirt 3.6 (it might become available soon on master, if you're feeling lucky...). VM-level QoS (available since 3.3) won't help you with administrative traffic (i.e. traffic that isn't going into / coming out of the VMs themselves). Also, I have more questions about this: - If I specify a VLAN on ovirtmgmt, then what happend on nodes? I'm afraid the nodes will lost the connection with each other nodes. If the switch allows this VLAN to reach all hosts, there shouldn't be a problem; since oVirt 3.4 the VLAN tagging should propagate to all active hosts. However, see my comment below concerning VM network. - Is it possible on a live system? What will happen with the mounted glustefs based datastores? I'm not knowledgeable about gluster specifics, but let's see if I can help. What's the current situation with the gluster network, is it already VLAN-tagged? If it is and you're not moving it to another interface on the hosts, I *think* things should be fine. - What does vm network mean on ovirtmgmt interface? Can I use this for seperate network traffic? This means that a bridge is created for this network on hosts. If VMs don't use this network (i.e. virtual interfaces are assigned profiles of ovirtmgmt), you can make it non-VM (with no VLAN tagging) and have it assigned to the same host interface as VLAN-tagged networks (I would say this is less risky than VLAN-tagging ovirtmgmt). My plan is - vlan.101 ovirtmgmt - vlan 102 glusterfs - vlan 103 migration - vlan 104 display What is the recommended procedure of this?

[ovirt-users] Cumulative VM network usage
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.

Re: [ovirt-users] Vlans and subnets
Hi Demeter, This is an issue others have stumbled onto before, so it probably needs to be fixed; it's sort of a chicken-and-egg problem. For the time being, I think the workaround is to set up your storage network manually on the host as vlan101 (in an oVirt-compatible manner) before running engine-setup. In engine-setup you would then name the vlan102 device for the management network (which is used to communicate with hosts). Setting up the storage network in an oVirt-compatible manner can be performed by pre-installing vdsm (i.e. yum install vdsm) yourself on your first host, then run something like: vdsClient -s 0 addNetwork bridge=storageNetworkName vlan=101 nic=eth0 \ BOOTPROTO=dhcp I hope I got it approximately right, can't commit that it's accurate :) I've also added specific answers to your questions below, please let us know if this does the trick or if you require more assistance.

Also, I have an another connection (eth1) with different subnet for internet acces and this is the default route. I would like to separate ovirt services, networks and glusterfs to different vlans/subnets by security reasons. But I don't know what services need to be on same vlan/subnets. My questions/goals - which services need to connect to another ? Could you be more specific? The management network is used to communicate between the engine and the hosts, the storage network is only used by the hosts (and not the engine) as far as I know. - Is hosted engine's vm need to be on same network with gluster ? To my understanding no, see above point. - Is hosted engine's vm need to be on same network with vdsm hosts? Yes, see above point :) - I want to separate ovirt/gluster networks from ovirt VM-s/public internet access Not sure how much separation you're looking to get, but shouldn't be a problem. For example, You can put the additional (public) networks on different VLANs and make sure to tag/untag packets as they enter/leave your oVirt deployment. Keep in mind to also configure the additional networks on the hosts and VMs. - I don't want to extra traffic on router Not sure about your topology, but if your hosts are on the same broadcast domain then there's no reason why this traffic will put unnecessary load on your router.

Re: [ovirt-users] Network usage is not updating in the ovirt panel

Re: [ovirt-users] Network usage is not updating in the ovirt panel
Hi Shanil, This file transfer should have been below the traffic threshold to be displayed; as you can see in your third screenshot, the average transfer rate was 213 KBps, which is about 1.5 Mbps, which is about 0.15% of the NICs' speed - whereas you'd only see traffic above 1%. You would need a higher-intensity transfer to verify... And in fact, using your QoS settings, you will never see any traffic, as your traffic limit is only 0.2% of the NICs' speed! And for future reference, when you take screenshots of the VM/interfaces secondary tab, it's best that you also click on the specific VM interface that should see the traffic - so its RX/TX rate is displayed in the statistics tab at the bottom-right.

I'm actually having issues across the board...maybe its because I'm
going against the design ideals but I was told that in order to use the
local storage on the box and sacrifice VM migration capabilities, all

Wait, what? :) This doesn't sound right. What is it that you're trying
to achieve exactly? I'm guessing you'll be able to achieve the same
thing just by pinning VMs to hosts (via the VM dialog) and using a
single DC.
However, I'm not sure you even need to do that... I don't use local
storage so I don't really know, but things will probably work even if
you don't do anything special (except migration might not work).
Second pain point is adding additional networks aside from the initial
management network doesn't seem to be very intuitive. I'm a network
engineer for a living...and I can't figure it out.
Third pain point is ovirt management UI requires a restart semi
frequently due to crashing.
Could you give any further details? Version you're using, exact
symptoms? This isn't by design :) And I haven't run into anything of the
sort.
I added the network under the networks tab, but I noticed it doesn't ask
any interface questions (ok, it could technically attempt arp on all
interfaces like a citrix netscaler). I notice theres no ifconfig changes
on the host. I also notice that the other interface has a bridge named
exactly as the management name in the UI; ovirtmgmt, which is bridged to
eth0. OK, so I create a bridge called utility (my network name) and
mapped it to a vlan tagged interface I had setup on eth1.21. Everything
looks identical to how ovirt setup the initial network. The interface
itself works, I can see things on the network etc. Traffic passes.
You shouldn't have to configure anything manually on a host, e.g. set up
bridges, oVirt does this for you. Once you create the network in the
tab, you can assign it to hosts by heading to the Host/Interfaces
secondary tab and clicking Setup Host Networks.
Once you do that - VMs using that network should be able to run on that
host.
Trying to run the VM results in errors because its failing network
filters, says it doesn't exist etc. All I want to do, is create a VM
with some memory, some disk, with a nic on a network, across individual
machines. My PXE provisioning will take over from there. Whats the best
way to do this? Sorry for all the questions -- your guys' response is
great, and I really appreciate the help thus far.
The exact message I get is:
Error while executing action:

It does not matter if template or instance type since instance types just
inherit the behavior of the templates so are inheriting also the bug/missing
logic etc.
For me it seems like a bug but not sure. Is there a reason why the NICs are
ignored when the VM is created from a template with NICs using API?
What I think is that since the NIC can have different profiles assigned and
this can be edited on the FE, this functionality of sending different profile
for the specific NIC is just not implemented on API level, so the API just
completely ignores the NICs.
What do you think Lior?
If I correctly understand what you mean, then that is the current
intended behavior - supplying NICs as part of VM creation isn't
supported, and there's this RFE to support it:
https://bugzilla.redhat.com/show_bug.cgi?id=69
My two original suggestions will apparently have to suffice until this
RFE is realised; either properly configuring the template's NICs before
VM creation or modifying the VMs' NICs following creation.
Hope this helps! Let us know please :)

I have gone back to my networks and checked them thoroughly and can’t see any issues, I have migrated the VM from one host to another and the condition persists in that it can ping the host that it is running on and the host can ping it (providing I turn off the firewall) numerous reboots etc and no change.

After setting it all up, loading the drivers etc it looks fine, but it seems like it has no network connectivity. This is odd as it is obtaining a DHCP address and it looks like it can browse for other windows systems on the network. But I can’t ping it, it can’t ping out and I can’t remote desktop into it. Normally this sounds like a firewall problem, but I disabled that immediately. It is using the virtio driver. It is connected to the default network ovirtmgmt which has a dhcp server on it. Ovirt-engine says the interface is up and connected and windows thinks it is connected to an unknown network with out internet access. I can’t ping the default gateway from the VM console. Seems silly, but I’ve kind of run out of things to try on this now. I am using VLAN tagging on the ovirt-engine network side of things and it is plugged into a trunked port… but I wouldn’t think that has anything to do with the VM itself as I am not doing anything with VLANs on the VM itself, it is just connected to it. All the host network/interfaces are pingable in the cluster as well.

Re: [ovirt-users] oVirt 3.5 test day - OptaPlanner integration
So the second test day went even worse - at first I had issues with missing packages for Fedora 20 (fixed during the test day itself) and started working on Fedora 19 instead. Then I hit some issue with HTTP requests from the ovirt-optimizer machine to the ovirt-engine (on port 80) seemingly being redirected to HTTPS - is this a change that took place after the first test day? Feature owner was very kind in helping me even though he was on a day off, built a patched-up package for me to test and found that connecting to port 443 works as expected (patches pushed to gerrit on the very same day). Unfortunately this was already late into the test day and I haven't gotten to test any non-trivial host/VM setup.

Re: [ovirt-users] Is there are fix or workaround for the Ovirt 3.3 Cluster and VDSM 4.14?
Hi! An upgrade would fix it. The general issue hasn't yet been fixed (looking at BZ 1077110) and I don't know whether it'll be backported when it does. I would edit the engine's DB and append 4.14 to the option_value column of the vdc_options table where option_name=SupportedVDSMVersions, then restart the engine. I think this should be enough.

I am a newbie to ovirt and I had a couple of questions and I was hoping I could get some help. 1. Does ovirt support openvswitch without going through Neutron? So far all the documents that I came across uses Neutron as an external network provider. At the moment it doesn't. However, this has been talked about and will probably be implemented at some point (though not sure when). In fact, if you're a developer, you could help make it happen yourself! A lot of the necessary nfrastructure has been recently laid down by this feature, which would only require someone to implement an OVS configurator: http://www.ovirt.org/Feature/NetworkReloaded 2. Is there a support for macvtap in ovirt? I couldn’t find anything on macvtap. Not at the moment, and I myself am not knowledgeable about macvtap. However, since Google tells me it should play well with libvirt, I'm guessing support for that might also be added by implementing a dedicated configurator. Following the said Google search however, I would be very interested to hear why it interests you, since oVirt handles bridge and tap device creation. What would be the gain in using specifically macvtap? I'm asking because this if there's good reason to do this, it might be prioritized in the future. Yours, Lior. I would appreciate your help.

[Users] Network custom properties
Hello all, Introducing the oVirt 3.5 feature of network custom properties: http://www.ovirt.org/Features/Network_Custom_Properties Essentially, this feature aims to solve two RFEs, that request the ability to set bridge and ethtool options on host interfaces from the GUI/REST: https://bugzilla.redhat.com/show_bug.cgi?id=1080984 https://bugzilla.redhat.com/show_bug.cgi?id=1080987 It will do so by adding custom properties (key:value pairs) to networks assigned to host interfaces, which can in turn be acted upon via hooks when e.g. a Setup Networks command is triggered. Two predefined keys will include bridge_opts and ethtool_opts, but any arbitrary custom property could be supplied as well. Please take a look at the detailed feature page and let me know if you have any comments. Yours, Lior. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Logical Network VLAN Tagging and DataCenters
Hi Simon, I think what you're experiencing is this: https://bugzilla.redhat.com/show_bug.cgi?id=1070835 So this is not by design, there shouldn't be any issue with having the same VLAN ID defined across multiple DCs. Should be fine when oVirt 3.4.1 is released, or using nightly build. Yours, Lior.

I am seeing a situation where if I have two Datacenters, both with a logical network that have the same vlan tag. E.G. DC = London, Logical network = prod, VLAN = 123 DC = Paris, Logical network = prod, VLAN = 123 If I edit one of the VM’s running in the “London” datacenter, the VM NIC shows up as empty even though if I click on the VM and go to the “Network Interfaces” tab at the bottom of the screen it lists up the “prod” network under “Network Name”. All works OK for VM’s that are assigned a logical network that is only defined once (i.e. has not been added to both datacenters). This configuration is on oVirt Engine 3.3.2-1.el6.

When trying to put such networks together via the Setup Networks dialog, users are currently informed that non-tagged VM networks can't exist on the same interface as tagged VM networks, and are advised to detach the non-tagged network.

Re: [Users] [SOLVED] Re: Networking questions (LONG)
Hi Alan, May I just inquire about the two alternative solutions that had been proposed here, and why you opted against? As a reminder, I'm referring to: 1. Using a firewall VM with one vNIC per VLAN network. 2. Using VDMS hooks to simulate TRUNK. Both of these should allow migration, etc. without any additional procurement, and require only the one firewall VM. Are the Lanner and dual-firewall solutions simpler? Yours, Lior. On 21/01/14 05:07, Alan Murrell wrote: I just thought I would reply back to my own thread with what my team and I have come up with. While I have marked this as Solved, don't get too excited; it is not exactly the resolution we were looking for, but is acceptable nonetheless. After some further digging around, we found that it is possible to pass hardware (including a NIC) through to a guest. Unfortunately, this renders the guest unable to be migrated to another host automatically. In a single-server setup (which many of our clients' setups are via VMware, currently0, this would not make a difference, since there is no other host to migrate to anyway. Son in those cases, not much changes. For multi-server setups, we have two choices: 1.) Forgo the virtual firewall and purchase a Lanner or similar hardware to install the firewall onto. Since a multi-server setup (at least two server + SAN) typically runs a minimum of $10K-$15K in hardware alone, an addition $300 or so for the Lanner (or similar hardware) would not increase the overall cost of the project in a significant way. (This option could of course be used in a single-server setup as well, but hardware cost is usually more of a factor with these setups for our clients) 2.) Setup a firewall guest on two of the hosts, and configure them in an active-passive fashion. As long as both of the hosts with the firewall VMs do not go down at the same time, then there should not be an issue. If a host with a firewall VM goes down, the other firewall VM will take over. So, those are the work-arounds that we have come up with (nothing new to anyone here, I am sure) until such time as OpenVSwitch gets adopted into oVirt/RHEV as either an easy-to-enable option, or as the standard/default switch. Anyway, this post was really more of a closure post so anyone coming across this thread in the future does not wonder what the ultimate outcome was. :-) -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Unfortunately can't rely on engine-vdsm duo to help out. Anything above the host line on the diagram is physical setup and is the only configuration that doesn't disconnect me from the net.

Once this survives service network restart I can proceed to VDSM install and then its straight forwardthat is until I'm trying to SYNC ovirtmgmt on host inside. I should mention after ovirt engine is working I destroy default cluster and create new local one. Obviously I cannot access logs since access to host is no longer but entire setup is scripted including provisioning so I can easily rebuild entire setup within 15 or so minutes by running a script. Anyone who would like to benefit from my findings can use this script and gain access to my host and learn with me on how to overcome this. From the above information I understand that you are still in the initial stages of installation and are not scared of starting anew. If that is the case, I would suggest that you do start from a clean DC again. Try to configure the management network as non-VM prior to adding any host, then add the hosts. As far as I know, this should provision the network correctly on the hosts to begin with (it should work when synchronizing it as well, but let's try this way and see if it works better). Script will provision the host (fresh os install), log in, get the files: ifcfg-eth0, ifcfg-ovirtmgmt, ifcfg-ovirtmgmt-range0, ovrit_answers and route-ovirtmgmt, then install epel 6-8, install pgp, localinstall ovirt-el6.10-1. install bridge-utils, upgrade, set hostname, then after reboot ssh alive, set local data,images,iso folders, install ovrit-engine, set ipv4 forwarding and proxy_arp=1, restart-network, and run engine-setup with ovirt_answers including cli and stop iptables as engine and vdsm rules still prevent connection if on. that's it. working system in 15 mins still to do is engine-api calls to create local cluster, join engine with vdsm local and setup private network with pfSense instance as router/nat/dhcp for 10.0.0.0/24 http://10.0.0.0/24 Peter ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

That would be doable, except I am not sure if there is a limit to the number of vNICs a VM could have and/or if there is an OS-level limit to how many? It is also a bit messier IMO, but that is more of a personal issue than a technical one, and one I could probably get over :-) oVirt does not enforce any sort of limit on the number of vNICs. I personally don't know about KVM or your VMs' OS, but this should be Googleable. When you say that oVirt currently doesn't allow creating VLANs inside VMs, are you referring to the use of VLAN interfaces like I describe (e.g., eth1.1, eth1.2, eth1.10, etc.)? If so, is that an oVirt limitation, or a KVM one? Yes, sorry, I realise now that my phrasing was only half-understandable. I indeed meant that oVirt doesn't support attaching more than one network to the same vNIC (be it VLAN-tagged or not). I doubt that this is a KVM limitation (but I'm no expert on KVM), I think it's just something that we haven't yet found a strong case for in oVirt. I have seen examples where one can create a Trunk with KVM and Open vSwitch, and I thought for some reason oVirt used Open vSwitch, but none of the commands I tried from the examples were found. A check of http://www.ovirt.org/Features/Node/OpenVSwitchSupport shows that indeed there does not appear to be any integration yet, and it is only 60% done :-( I actually know nothing of the link you provided, but I can offer alternatives. If you REALLY want to use OVS with oVirt NOW, you could take advantage of its integration with OpenStack Neutron. That would require you to install another machine (should be possible on an all-in-one setup too) as a Neutron server. This might go smoothly or it might cause you some headaches. http://www.ovirt.org/Features/Detailed_OSN_Integration It will probably become possible in the future to use OVS with oVirt directly (although I can't promise or commit on the time frame) by leveraging a development process that's going on in VDSM networking right now. In fact, if you're a developer you could help make it happen and control the time frame yourself by contributing to an OVS backend. http://www.ovirt.org/Feature/NetworkReloaded With regards to using the dummy interfaces, I realised I probably do not need to add them to a bridge, since they would be physical NICs in production (this is just for testing). I initially did create the ovirtvm bridge before I realised that, but have made them stand-alone NICs with no IPs attached to them, but they are not green in oVirt when I try to attach my logical networks to them under Networks Hosts vmhost01 Setup Host Networks. When I am in Setup Host Networks, I see my dummy interfaces, but they have a red dot instead of a green one (like what eth0 has). I can my logical networks to them, but the Network Device Status has a red arrow pointing down. Here are my ifcfg-dummy* files: I'm not an expert on these things, but this Down status is basically the administrative link state on the host. From my experience when logical networks are attached via the Setup Networks dialog, it does go up, although I haven't tried without an IP address. Also, it's worth trying to see if the actual networking works even if the NIC shows as down, or to ifup the NIC manually if it doesn't. --- ifcfg-dummy0 --- DEVICE=dummy0 ONBOOT=yes TYPE=Ethernet DELAY=0 BOOTPROTO=none NM_CONTROLLED=no STP=no --- ifcfg-dummy0 --- My ifcfg-dummy1 is identical, except of course it has DEVICE=dummy1 in it. The interfaces do come up on the host, but as I said, in Setup Host Networks they have a red dot instead of a green one. Perhaps I do need to assign an IP? I can maybe assign a dummy one (i.e., one that I would never use)? -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Networking questions (LONG)
Hello Alan, On 09/01/14 10:07, Alan Murrell wrote: Hello, I am evaluating oVirt as a replacement/alternative to VMware deployments we typically do. I have installed and all-in-one setup on a test box (which itself used to be an ESXi server), but it only has one NIC. I trying to duplicate our typical configuration we do in VMware, which is this: 1.) we create several port groups on the vSwitch, each assigned a VLAN ID, such as: - VLAN001 (VLAN ID: 1) - VLAN002 (VLAN ID: 2) - VLAN009 (VLAN ID: 9) - VLAN010 (VLAN ID: 10) - VLAN200 (VLAN ID: 200) - TRUNK (VLAN ID: 4095 - in VMware-world, VLAN ID 4095 is all VLANS and basically just passes the VLANs through to whatever is attached to the port group for the VM to handle) 2.) We assign VMs to port groups appropriate for the VLAN they are part of. 3.) The only VM that has a NIC assigned to the TRUNK port group is the firewall (which is Linux), and we create VLAN interfaces on it (i.e., eth1.1, eth1.2, eth1.10, eth1.200). The firewall VM acts as the router between the various VLANs. To replicate the above in oVirt, I created logical networks for each VLAN, and assigned the appropriate VLAN ID. It seems oVirt/KVM does not have an equivalent for VMware's VLAN ID of 4095, so after some searching around, so for the TRUNK network, I left it with no VLAN assigned. Because i cannot add VLAN and non-VLAN networks to the same physical NIC, after some searching around, it looks like I may have to utilise two NICS: one for the VLAN networks and one for the TRUNK network. That is true. One non-VLAN network can in fact sit on the same NIC with VLAN networks, but it has to be non-VM. However, I'm not sure that you in fact need a TRUNK VM network in oVirt. If you want your firewall VM to get all traffic from the VLANs, you could create a vNIC for each network, to which you'll attach a profile (oVirt's equivalent of port group if I'm not mistaken) of the corresponding network. The host can remain with just the VLAN networks attached to its NICs, without a designated TRUNK. This way the firewall VM will get something like eth1 for VLAN 1, eth2 for VLAN 200 and so forth, which might be close enough to what you described on your previous setup (oVirt currently doesn't allow creating VLANs inside VMs). And if I correctly understood your needs it will save you the trouble you described below (well, you would need the one dummy interface). Because, at this point, I am not yet concerned with making the test VMs I will be setting up be accessible from outside the virtual lab environment (i.e., everything will communicate within my oVirt server/network for now), I am trying to make use of dummy interfaces, but I am not sure the best way to make use of this. I am able to create the dummy* interfaces and have them show up in oVirt, but I am not sure of how they should be setup. Here is what I am *thinking* should be done, but want to make sure it is correct before getting too deep: - I will use the physical NIC for management, therefore the ovirtmgmt bridge with eth0 assigned to it will remain as-is - Create two dummy interfaces: dummy0 and dummy1 - Create a new bridge, ovirtvm and assign dummy0 and dummy1 to it This is something that currently can't be done from within the oVirt engine, but if my above suggestion works for you then it won't be needed. - Attach the VLAN-enabled networks to dummy0 - Attach the TRUNK network to dummy1 Would the above be the way to go about this? The one thing I am not sure of is whether or not having no VLAN assigned (on the TRUNK network) accomplishes the same this as the VLAN ID 4095 in VMware: will oVirt/KVM just pass the traffic through for the VM attached to it to deal with? Thanks for reading this far, and I appreciate any help you might be able to lend in the above. -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Network profile lost after host edit
Hey Simon, It actually doesn't surprise me that it's related to the template, because we had other issues that were template-related in this dialog. However, I haven't been able to reproduce it myself when working from the master branch. So either it got fixed between 3.3.1 and now, or I just didn't try anything complex enough. If you could find some consistent way to reproduce the bug (BTW, it's definitely a bug and not by design), then we could determine whether it has indeed been solved in the meantime. And if not, we'll make sure that it's fixed. Yours, Lior. On 12/12/13 23:52, Simon Barrett wrote: Lior, I'm running 3.3.1. I think it may be related to how I created the VM's.

Re: [Users] Host Network QoS feature
Hi Sven, Thanks for your input, see response below. On 25/11/13 10:59, Sven Kieske wrote: Hi, I have two thoughts on QoS: First: You mention just QoS for VMs, Hosts and in the future DCs, what about Cluster level QoS? Good point. Cluster level would be similar in implementation to DC level (and might be as useful), the point being that both are relatively complex and out of the scope of this current feature. I'll update the feature page to mention the cluster level as well. Second: It would also be very useful to track some statistics, like traffic consumed per vm / host, e.g. for accounting, maybe the ceilometer project from openstack could provide some of this information? It might be useful to integrate with Ceilometer, oVirt will definitely try to leverage OpenStack wherever possible. Specifically for the billing use case (which relates more to VM QoS than to host QoS), maybe someone who knows more about SLA than me would care to comment. What do you think?

Re: [Users] What should be the default for adding network from specific Cluster
The upside is that we'd keep consistency with the context (i.e. operation as part of specific cluster). The downside would be that users might not always aware of the context and thus might be confused by the different behavior of the seemingly same dialog.

In 3.3 we can add Network from the DataCenter tab and then that network will be attached to all Clusters of that DataCenter. When adding network from specific Cluster the default behavior today is to attach that network to all the Clusters under the same DataCenter as well. We think that the right behavior should be add that network by default only to the Cluster from which we add that Network from. Any feedback will be appreciated.
