[Users] Replacing ISO domain
by Gabi C 09 Jan '14

09 Jan '14

Hello! 1 Ovirt-engine + 2 nodes with Glusterfs on them (replicate), 1 ISO domain, 1 Export domain. ISO domain is created at ovirt-setup time on ovirt-engine host.How can I replace this ISO domain with a new, bigger, one on another machine?

[Users] Creation of preallocated disk with Gluster replication
by gregoire.leroy＠retenodus.net 09 Jan '14

09 Jan '14

Hello, I have a Gluster volume in distributed/replicated mode. I have 2 hosts. When I try to create a VM with a preallocated disk, it uses 100% of the available CPU and bandwidth (I have 1 Gigabit network card). The result is I can't even create a preallocated disk because the engine detects a network failure. I get that kind of messages in /var/log/messages : " Jan 2 14:13:54 localhost sanlock[3811]: 2014-01-02 14:13:54+0100 167737 [3811]: s4 kill 21114 sig 15 count 1 Jan 2 14:13:54 localhost wdmd[3800]: test failed rem 51 now 167737 ping 167718 close 167728 renewal 167657 expire 167737 client 3811 sanlock_ef4978d6-5711-4e01-a0ec-7ffbd9 cdbe5d:1 " And that in the Ovirt Gui : " 2014-janv.-02, 15:35 Operation Add-Disk failed to complete. 2014-janv.-02, 15:35 Storage Pool Manager runs on Host HOST2 (Address: X.X.X.X). 2014-janv.-02, 15:35 Invalid status on Data Center GlusterSewan.

I understand that the creation of a 10 Go disk image generates a lot of traffic, but is there a way to limit it so that it doesn't have an impact on the production ? Furthermore, Why does it use so much CPU ressources ? I can see on my monitoring graph a big peak of CPU usage when I launched the operation (probably until 100%). Thank you, Regards, Grégoire Leroy

Re: [Users] VSDM?s logrotate makes Hosts fill up var, eventually
by Juan Pablo Lorier 09 Jan '14

Hi Dan, If my opinion is worth, I use logs all the time as my setup is evolving all the time and have issues quite often, so I rather use space in logging too much than loose information I need in regular bases. Regards,

So be warned: if you have this hardware check very carefully your network mount points inside Vms If you have already tested this configuration and have this working please let me know.

[Users] Specifying values for cert, key, and CA for ovirt-shell
by Bob Doolittle 09 Jan '14

09 Jan '14

Hi, I want to run ovirt-shell directly (as root) on the Engine. Presumably all the files I need for CA, key, and cert are in the /etc/pki area. But when I use the attached .ovirtshellrc file I get: error: [Errno 336265218] _ssl.c:341: error:140B0002:SSL routines:SSL_CTX_use_PrivateKey_file:system lib How can I specify an appropriate configuration to get this working? I would prefer to keep using SSL if possible. Thanks, Bob

[Users] Bug? in tweak vm instance via REST/JSON 3.3.2
by Sven Kieske 09 Jan '14

09 Jan '14

Hi, we got a problem with starting a vm after changing some of its parameters via REST (JSON) this is the command to create the vm (this works): POST request on https://virt-mgmt-01.internal/api/vms/ {"name":"vr00002","cluster":{"id":"2ad11b5e-9e74-499a-b317-5a9a3027cfca"},"template":{"id":"374a12df-5ffc-4feb-a2bf-c912f059675f"}} Then we tweak memory and cpu: PUT request on https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f {"memory":2048,"cpu":{"topology":{"sockets":1,"cores":1}}} and then we start it: POST request on https://virt-mgmt-01.internal/api/vms/42dba82f-e7ea-40ff-a76e-70056912b47f/… {"vm":{"initialization":{"cloudInit":{"host":{"address":"vr00002"},"networkConfiguration":{"nics":{"nics":[{"name":"eth0","bootProtocol":"STATIC","network":{"ip":{"address":"10.0.1.12","netmask":"255.255.255.252","gateway":"10.0.1.9"}},"onBoot":true}]},"dns":{"servers":{"hosts":[{"address":"46.30.62.99"},{"address":"46.30.62.98"},{"address":"46.30.62.97"}]}}},"users":{"users":[{"name":"root","password":"lPzYG06qV63+Tne7"},{"name":"vr00002","password":"lPzYG06qV63+Tne7"}]},"files":{"files":[{"name":"\/foo\/ip-configuration","content":"extern_v4address1 185.15.194.7\npassword1 lPzYG06qV63+Tne7","type":"PLAINTEXT"}]}}}}} the error we get: Operation Failed","detail":"[Cannot run VM. There is no host that satisfies current scheduling constraints. See bellow for details:]" when we start the vm without altering memory and cpu it starts just fine. Is this not supported via JSON, or is this a bug? PS: BTW there seems to be a spelling bug in the error message ("bellow"). -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Experience with low cost NFS-Storage as VM-Storage?
by Sven Kieske 09 Jan '14

09 Jan '14

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] GlusterFS Distributed Replicate

Hi, in a 2 node cluster you can set the path to localhost:volume. If one host goes down and SPM role switches to the remaining running host, your master domain is still accessible and so your VMs stay up and running.

[Users] too many bouces information message..
by Gianluca Cecchi 09 Jan '14

09 Jan '14

Already received some weeks ago this kind of message I just received today: " Your membership in the mailing list Users has been disabled due to excessive bounces The last bounce received from you was dated 08-Jan-2014. You will not get any more messages from this list until you re-enable your membership. You will receive 3 more reminders like this before your membership in the list is deleted. To re-enable your membership, you can simply respond to this message .. " At the mean time I just re-enabled my membership receiving confirmation message. What could be the reason? I'm only normally using via web my gmail account that I use for other mailing lists too, without any problem.... A difference is that I statistically find more messages from the list that gmails initally puts into spam and that I mark as "not spam".... Any hint here? Thanks, Gianluca

I asked for 3.3.4 target release to be added, but i think folks should consider if to push bugs to 3.3.4, or to 3.4.0 by now.

[Users] Need to recreate public RSA key on node
by Bob Doolittle 08 Jan '14

08 Jan '14

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] Help - Cannot run VM. Invalid time zone for given OS type.
by Dan Ferris 08 Jan '14

08 Jan '14

Hi, Has anyone run across this error: Cannot run VM. Invalid time zone for given OS type. The OS type for these VMs is set to Linux Other. They were all exported from an Ovirt 3.2 cluster and are being reimported into an Ovirt 3.3 cluster. None of these VMs will boot. We also can't delete them because delete protection is enabled and we can't edit the VM to turn off delete protection. Does anyone know what this error means exactly and how to fix it? Thanks, Dan

[Users] Deleting Storage Connection
by Nauman Abbas 08 Jan '14

08 Jan '14

Hello all I want to delete a storage connection since I'm adding an ISO Domain and it gives me the error "Storage connection already exists.". I'm trying to go for this: http://www.ovirt.org/Features/Manage_Storage_Connections#Delete_connection_… But it just shows me some link and some script. I don't know how use it. A little guidance on it would be great. Sorry for being a noob.

[Users] tuned profile for Centos hosts -- new Bugzilla or Regression
by Ted Miller 08 Jan '14

08 Jan '14

--_000_a584ee1c0d4e40a2ae295cf23111628bDM2PR05MB320namprd05pro_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable 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. At the = time I first ran into it, this was a fatal error. It is now just a warning= , so it does not prevent installing a host. But, as a warning, a lot of pe= ople are probably missing it. When using Centos 6 as the host OS, the script tries to install a "rhs-virt= ualization" profile. That profile is not included in Centos. I substitute= d the "virtual-host" profile. I believe that this may be a regression as a result of Bugzilla 987293<http= s://bugzilla.redhat.com/show_bug.cgi?id=3D987293>, where "rhs-virtualizatio= n" was substituted for "virtual-host" for RHEV + RHS. I am guessing that w= hatever is used as a switch to determine RHEV + RHS is also shoving Centos = into that same path, which is not appropriate. My suggestion would be to write the script so that it uses "rhs-virtualizat= ion" when present, and if it is not present, then it falls back to "virtual= -host". (I don't know what (if any) differences there are between the two = profiles.) Should I open a new bug, make a comment on 987293, or take some other path?

[Users] how to temporarily solve low disk space problem preventing start of VM
by Gianluca Cecchi 07 Jan '14

07 Jan '14

Hello, test cluster with two nodes and GlusterFS DC on f19 and 3.3.2, using gluster version 3.4.2 from f19 updates-testing repo. Unfortunately I have only small local disk quite occupied by existing VMs. About 4Gb free. I had VMs started and then I shutdown them. Trying to power on any VM I get: Error while executing action: c6s: Cannot run VM. Low disk space on target Storage Domain gvdata. On SPM node (node02) that is the only one active I have: /dev/mapper/fedora-DATA_GLUSTER 30G 23G 7.8G 75% /gluster/DATA_GLUSTER node01.mydomain:gvdata 30G 26G 4.6G 85% /rhev/data-center/mnt/glusterSD/node01.mydomain:gvdata Can I tweak this low disk warning in any way? How does engine make this kind of check? Thanks in advance Gianluca

[Users] python SDK remove VM once the storage is formatted/detached.
by karthik S 06 Jan '14

06 Jan '14

Is there a way to remove VMs entries from rhev manager using python ovirt-sdk "once the storage becomes unavailble" . - Something equivalent to "Remove from Inventory" in Vmware vsphere. ? Currently I get into the postgres db and delete the entries, manually. -Karthik

[Users] Stopping glusterfsd service shut down data center
by Amedeo Salvati 06 Jan '14

06 Jan '14

Hi all, I'm testing ovirt+glusterfs with only two node for all (engine, glusterfs, hypervisors), on centos 6.5 hosts following guide at: http://community.redhat.com/blog/2013/09/up-and-running-with-ovirt-3-3/ http://www.gluster.org/2013/09/ovirt-3-3-glusterized/ but with some change like setting on glusterfs, parameter cluster.server-quorum-ratio to 50% (due to prevent glusterfs to go down if one node goes done) and option on /etc/glusterfs/glusterd.vol "option base-port 50152" (due to libvirt port conflict). So, with the above parameter I was able to stop/reboot node not used to directly mount glusterfs (eg lovhm002), but when I stop/reboot node, that is used to mount glusterfs (eg node lovhm001), all data center goes done, especially when I stop service glusterfsd (not glusterd service!!!), but the glusterfs still alive and is reachable on node lovhm002 that survives but ovirt/libvirt marks DC/storage in error. Do you have any ideas to configure DC/Cluster on ovirt that remains aware if node used to mount glusterfs goes down? This is a sample vdsmd.log on node that remains on-line (lovhm002) when I stopped services glusterd and glusterfsd node lovhm001: Thread-294::DEBUG::2014-01-05 19:12:32,475::task::1168::TaskManager.Task::(prepare) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::finished: {'info': {'spm_id': 2, 'master_uuid': '85ad5f7d-3b67-4618-a871-f9ec886020a4', 'name': 'PROD', 'version': '3', 'domains': '85ad5f7d-3b67-4618-a871-f9ec886020a4:Active,6a9b4fa6-f393-4036-bd4e-0bc9dccb1594:Active', 'pool_status': 'connected', 'isoprefix': '/rhev/data-center/mnt/lovhm001.fabber.it:_var_lib_exports_iso/6a9b4fa6-f393-4036-bd4e-0bc9dccb1594/images/11111111-1111-1111-1111-111111111111', 'type': 'GLUSTERFS', 'master_ver': 2, 'lver': 3}, 'dominfo': {'85ad5f7d-3b67-4618-a871-f9ec886020a4': {'status': 'Active', 'diskfree': '374350675968', 'alerts': [], 'version': 3, 'disktotal': '375626137600'}, '6a9b4fa6-f393-4036-bd4e-0bc9dccb1594': {'status': 'Active', 'diskfree': '45249200128', 'alerts': [], 'version': 0, 'disktotal': '51604619264'}}} Thread-294::DEBUG::2014-01-05 19:12:32,476::task::579::TaskManager.Task::(_updateState) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::moving from state preparing -> state finished Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::939::ResourceManager.Owner::(releaseAll) Owner.releaseAll requests {} resources {'Storage.2eceb484-73e0-464a-965b-69f067918080': < ResourceRef 'Storage.2eceb484-73e0-464a-965b-69f067918080', isValid: 'True' obj: 'None'>} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::976::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::615::ResourceManager::(releaseResource) Trying to release resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::634::ResourceManager::(releaseResource) Released resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' (0 active users) Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::640::ResourceManager::(releaseResource) Resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' is free, finding out if anyone is waiting for it.

[Users] Cannot add Host. Host with the same address already exists.
by Matt . 06 Jan '14

06 Jan '14

Hi All, Ovirt 3.3.3 I have removed a host from the gui and want to re-add it, there was something wrong with the installation of this host. When adding the host I get: "Error while executing action: Cannot add Host. Host with the same address already exists." It seems that the host is still in the DB somewhere and it is, I see some NULL columns for that host because it's actually not really "there" anymore and stuff like statics are not updated. I need to clean this one out, how can I accomplish this without getting a "dirty" DB ? Thanks! Cheers, Matt

[Users] Another issue - VM Networking
by Dan Ferris 05 Jan '14

05 Jan '14

I've run into another issue with Ovirt 3.3.2. We have a 2 node VM cluster with Fibre Channel storage. After upgrade everything to FC 19 and installing Ovirt 3.3 from scratch one of the nodes has network issues. The issue is that when we start a VM on the node, the VM cannot access the network. No ping, no ssh, nothing. However, if I try to ping the VM, I can see the ICMP traffic on the ethernet VLAN interface and the bridge interface. I cannot see any traffic on the VM tap interface. If we migrate the VM from the faulty node to the other node that works, and then back, the network will start to work. However, if the VM is shut down the network will fail again when it's booted on the faulty node. Does anyone have any ideas about this particular problem? Thanks, Dan

[Users] Stopping glusterfsd service shut down data center
by Amedeo Salvati 05 Jan '14

05 Jan '14

Hi all, I'm testing ovirt+glusterfs with only two node for all (engine, glusterfs, hypervisors), on centos 6.5 hosts following guide at: http://community.redhat.com/blog/2013/09/up-and-running-with-ovirt-3-3/ http://www.gluster.org/2013/09/ovirt-3-3-glusterized/ but with some change like setting on glusterfs, parameter cluster.server-quorum-ratio to 50% (due to prevent glusterfs to go down if one node goes done) and option on /etc/glusterfs/glusterd.vol "option base-port 50152" (due to libvirt port conflict). So, with the above parameter I was able to stop/reboot node not used to directly mount glusterfs (eg lovhm002), but when I stop/reboot node, that is used to mount glusterfs (eg node lovhm001), all data center goes done, especially when I stop service glusterfsd (not glusterd service!!!), but the glusterfs still alive and is reachable on node lovhm002 that survives but ovirt/libvirt marks DC/storage in error. Do you have any ideas to configure DC/Cluster on ovirt that remains aware if node used to mount glusterfs goes down? This is a sample vdsmd.log on node that remains on-line (lovhm002) when I stopped services glusterd and glusterfsd node lovhm001: Thread-294::DEBUG::2014-01-05 19:12:32,475::task::1168::TaskManager.Task::(prepare) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::finished: {'info': {'spm_id': 2, 'master_uuid': '85ad5f7d-3b67-4618-a871-f9ec886020a4', 'name': 'PROD', 'version': '3', 'domains': '85ad5f7d-3b67-4618-a871-f9ec886020a4:Active,6a9b4fa6-f393-4036-bd4e-0bc9dccb1594:Active', 'pool_status': 'connected', 'isoprefix': '/rhev/data-center/mnt/lovhm001.fabber.it:_var_lib_exports_iso/6a9b4fa6-f393-4036-bd4e-0bc9dccb1594/images/11111111-1111-1111-1111-111111111111', 'type': 'GLUSTERFS', 'master_ver': 2, 'lver': 3}, 'dominfo': {'85ad5f7d-3b67-4618-a871-f9ec886020a4': {'status': 'Active', 'diskfree': '374350675968', 'alerts': [], 'version': 3, 'disktotal': '375626137600'}, '6a9b4fa6-f393-4036-bd4e-0bc9dccb1594': {'status': 'Active', 'diskfree': '45249200128', 'alerts': [], 'version': 0, 'disktotal': '51604619264'}}} Thread-294::DEBUG::2014-01-05 19:12:32,476::task::579::TaskManager.Task::(_updateState) Task=`a003cde0-a11a-489e-94c2-611f3d096a81`::moving from state preparing -> state finished Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::939::ResourceManager.Owner::(releaseAll) Owner.releaseAll requests {} resources {'Storage.2eceb484-73e0-464a-965b-69f067918080': < ResourceRef 'Storage.2eceb484-73e0-464a-965b-69f067918080', isValid: 'True' obj: 'None'>} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::976::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::615::ResourceManager::(releaseResource) Trying to release resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::634::ResourceManager::(releaseResource) Released resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' (0 active users) Thread-294::DEBUG::2014-01-05 19:12:32,476::resourceManager::640::ResourceManager::(releaseResource) Resource 'Storage.2eceb484-73e0-464a-965b-69f067918080' is free, finding out if anyone is waiting for it.

[Users] Centos 6.5 host configuration script -- a tale begun
by Ted Miller 05 Jan '14

--_000_22f073c8f28e423a8959bb2687b19cb9DM2PR05MB320namprd05pro_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable I have been working since Monday to get a Centos 6.5 host node added to ovi= rt. Since 6.5 is just out, I figured I might as well use the latest and gr= eatest to build my host. Today I succeeded (I think). I have not actually= added a VM to the host, but at least ovirt is willing to accept that the h= ost is part of the default cluster. My next task will be bringing up glust= er on that same node. Since I will be doing at least three more hosts, I wrote a shell script to = do a the setup that is needed to make the ovirt process succeed. No, I do not have a similar script for the engine. I got that running unde= r Centos 6.4 in a VM, without too much problem. That VM is temporarily run= ning on a KVM host (but that host is not under ovirt). Feel welcome to stare at or run my script and make any comments or observat= ions. * The script is run after a clean install of Centos 6.5 from the "minim= al" ISO. * I will try to remember what each element was there for, if anything i= s not clear. * There are probably a few (not many) things there that are not needed * Mostly they result in doing something ahead of time that ovirt was= going to do later anyway. * Feel free to point out a better way to do whatever needs to be done. * Bits and pieces of the script were stolen from googleing here and the= re. * Parts of the script were cooked up by stewing logs over low heat unti= l something useful bubbled to the top. * The number of clean reinstalls to test the script is beyond count. * I almost broke down and learned how to write a kickstart file (but= didn't). * No guarantees or representations. * So far this script has been tested on exactly one set of bare-meta= l hardware * That hardware is not server-grade. (ovirt keeps complaining bec= ause I have not configured Power Management :) * There are a few things that are personal preferences (things I instal= l on all my Linux machines) * I believe those preferences are clearly marked. * I am leaving them in because they may (incidentally) be installing= some dependencies that influence the outcome of the process. I hope to see a day when a similar script is either not needed, or is avail= able and maintained as part of the Centos distro, or as part of ovirt. Mea= nwhile we try to muddle through. I will copy my script into this webmail interface (OWA) (since I am writing= at home and this is all I have to work with) and see how bad it mangles it= . You'll probably need a wide window so that lines don't wrap, as Microsof= t thinks this OWA interface doesn't ever need to let me specify text as "pr= eformat".

[Users] qemu-img-rhev can't handle "-s" parameter

Hello, I used qemu-img-rhev-0.12.1.2-2.355.el6 successfully with -s parameter, but now qemu-img-rhev-0.12.1.2-2.415.el6 (latest atm) errors out with: convert: invalid option -- 's' What am I missing? Do I need any special rpmbuild switches or something? I see the spec already says "rhev 1" which should be enough. Regards, Lucian -- Sent from the Delta quadrant using Borg technology!

[Users] oVirt@FOSDEM 2014 sync

Hi all, keeping our FOSDEM tradition (from last year ;) we will be using a pad [1] to synchronize our activities which works very well. I'll make sure to print it, so we'll have a hard copy available in place. If you're coming and wish to help, feel free to register inside. Thanks and see you there!

It would be good to understand why this happened in the first place and what is the current situation below. do you know why the snapshots were broken? can you please attach engine and vdsm logs? can you also run tree on /rhev on the host and put results in a file? finally, if you could run a query in the db to get the current snapshots in db and also run lvs (for iscsi) or ls on the image dir in the domain (for nfs)? I am adding Liron, Eduardo and Federico to help investigate this issue and help you remove the snapshots Thakns, Dafna On 01/02/2014 10:53 AM, Maurice James wrote: > I only want to get rid of the snapshots > > -----Original Message----- > From: Dafna Ron [mailto:dron@redhat.com] > Sent: Thursday, January 02, 2014 4:59 AM > To: Maurice James > Cc: users(a)ovirt.org; eduardo Warszawski > Subject: Re: [Users] Broken Snapshots > > do you want to get rid of the snapshot or the entire disk? adding Eduardo. > > > On 01/01/2014 11:16 PM, Maurice James wrote: >> How do I get rid of broken snapshots?

Dear All, Is there a way, when you create a new vm in ovirt, the Name you choose for the vm, reflects the hostname of the vm? Kind Regards, Koen

[Users] Error on Setting up VLAN
by Alessandro Bianchi 01 Jan '14

01 Jan '14

Hi everyone and happy new year first ! I'm setting up a test host using VLAN It holds 2 VM's so I - Stopped the two VMs and removed the "public_10" network from the NIC - edited the "public_10" network, checked "enable VLAN tagging" and set 10 as VLAN identifier - assigned the "new" edited network to the VMs NIC - edited the HOST network, clicked the pencil on the relevant NIC and clicked "sync network" since it showed the network as "not synced" Ovirt tried to setup the network but ended with "cannot up interface" error and I lost contact with the node Ovirt is 3.3.2 on Fedora 19 (it is AIO) Here is the log: 53244 Thread-52989::DEBUG::2014-01-01 16:58:16,938::BindingXMLRPC::974::vds::(wrapper) client [172.16.0.5]::call setupNetworks with ({'public_10': {'nic': 'p5p1', 'vlan': '10', 'ipaddr': '10.0.0.5', 'netmask': '255.255.255.0', 'STP': 'no', 'bridged': 'true', 'gateway': '10.0.0.254'}}, {}, {'connectivityCheck': 'true', 'connectivityTimeout': 120}) {} flowID [49756c97] 53245 Thread-52925::DEBUG::2014-01-01 16:56:39,737::BindingXMLRPC::974::vds::(wrapper) client [172.16.0.5]::call ping with () {} flowID [64a8776] 53246 Thread-52925::DEBUG::2014-01-01 16:56:39,738::BindingXMLRPC::981::vds::(wrapper) return ping with {'status': {'message': 'Done', 'code': 0}} 53247 Thread-52924::ERROR::2014-01-01 16:56:39,802::API::1262::vds::(setupNetworks) bridge public_10 has interfaces set(['vnet0', 'vnet2']) connected 53248 Traceback (most recent call last): 53249 File "/usr/share/vdsm/API.py", line 1260, in setupNetworks 53250 supervdsm.getProxy().setupNetworks(networks, bondings, options) 53251 File "/usr/share/vdsm/supervdsm.py", line 50, in __call__ 53252 return callMethod() 53253 File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda> 53254 **kwargs) 53255 File "<string>", line 2, in setupNetworks 53256 File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod 53257 raise convert_to_error(kind, result) 53258 ConfigNetworkError: (28, "bridge public_10 has interfaces set(['vnet0', 'vnet2']) connected") 53259 Thread-52924::DEBUG::2014-01-01 16:56:39,808::BindingXMLRPC::981::vds::(wrapper) return setupNetworks with {'status': {'message': "bridge public_10 has interfaces set(['vnet0', 'vnet2']) connected", 'code': 28}} ifcfg-p5p1 (before loosing connection) [root@hypervisor ~]# cat /etc/sysconfig/network-scripts/ifcfg-p5p1 DEVICE=p5p1 ONBOOT=yes HWADDR=00:50:fc:85:9b:76 BRIDGE=public_10 NM_CONTROLLED=no STP=no ifcfg-public_10 DEVICE=public_10 ONBOOT=yes TYPE=Bridge DELAY=0 NM_CONTROLLED=no STP=no IPADDR=10.0.0.5 NETMASK=255.255.255.0 DEFROUTE=yes GATEWAY=10.0.0.254 PEERDNS=yes DNS1=8.8.8.8 DNS2=8.8.4.4 How may I amend the configuration files?
