Hello, I have a newly created datacenter in 3.2.1 with f18 host where ovirtmgmt is set as vlan. host is installed but after some minutes I get this messages: Host management02 moved to Non-Operational state because interfaces 'em1.311' are down but are needed by networks 'ovirtmgmt' in the current cluster from an operating system point of view it seems that all is ok on the host [root@management02 ~]# ip addr list 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:15:17:b4:99:3c brd ff:ff:ff:ff:ff:ff 3: em2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:15:17:b4:99:3d brd ff:ff:ff:ff:ff:ff inet 213.205.41.202/26 brd 213.205.41.255 scope global em2 4: em1.311@em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovirtmgmt state UP link/ether 00:15:17:b4:99:3c brd ff:ff:ff:ff:ff:ff 5: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:15:17:b4:99:3c brd ff:ff:ff:ff:ff:ff inet 10.39.71.12/26 brd 10.39.71.63 scope global ovirtmgmt 7: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 36:98:c3:39:5f:43 brd ff:ff:ff:ff:ff:ff 8: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 9: bond4: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 10: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 11: bond2: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 12: bond3: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff [root@management02 ~]# ethtool em1 Settings for em1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes [root@management02 ~]# ethtool em1.311 Settings for em1.311: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: on Link detected: yes On engine [root@management01 ~]# ip addr list 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:15:17:b1:1f:e8 brd ff:ff:ff:ff:ff:ff 3: em2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:15:17:b1:1f:e9 brd ff:ff:ff:ff:ff:ff inet 213.205.41.201/26 brd 213.205.41.255 scope global em2 4: em1.192@em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:15:17:b1:1f:e8 brd ff:ff:ff:ff:ff:ff inet 192.168.230.1/24 brd 192.168.230.255 scope global em1.192 5: em1.311@em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:15:17:b1:1f:e8 brd ff:ff:ff:ff:ff:ff inet 10.39.71.11/26 brd 10.39.71.63 scope global em1.311 [root@management01 ~]# ethtool em1 Settings for em1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes [root@management01 ~]# ethtool em1.311 Settings for em1.311: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: on Link detected: yes what can be the cause? what is the check that runs and move the host to non-operational?

[Users] How to import KVM machines into oVirt iSCSI
by Nicolas Ecarnot 12 Apr '13

12 Apr '13

Hi, Reading the docs all day long helped me to setup a nice Data center in iSCSI mode, connected to a big LUN in a san. Many many points are working, mostly thanks to you, people of this list. Apart from this oVirt setup (1 manager, 3 nodes, 1 san), I have a completely separated ubuntu hypervisor running a standalone local KVM with a local storage. I have not a clear view of how I will manage to import these VM into oVirt. Of course, I've read about ovirt-v2v (and its huge amount of dependencies...), but I'm not sure this is the way I have to follow? As far as I've understood, v2v seems to be dedicated to connection between oVirt datacenters, or vmware or Xen plateforms, but I see nothing about the connection to a distant standalone KVM hypervisor. One more thing that is unclear to me, and seems related, is the notion of export / import domain. I read that this principle could allow me to export (then to backup) my VMs. This could help me to import some VMs. But I read that this export domain has to be the same type of my datacenter (iscsi), so this is not helping me with my standalone kvm hypervisor. I'd be glad to get some light on these points. -- Nicolas Ecarnot

[Users] Ipa server inside ovirt itself. ..
by Gianluca Cecchi 12 Apr '13

12 Apr '13

Hello, I have a test environment where I am short of hw. My engine is based on fedora 18 and I would like to test freeipa on centos 6. What are the drawbacks of creating a vm that is also one authentication domain for ovirt itself (apart the obvious ones)? Can i set it so that is the first to start? Can i set a subset of VMs to start only if this one is up and is giving ipa service (for example through a test connect command? ) Thanks Gianluca

Re: [Users] host goes to non-operational because interface down message

Gianluca, Thanks for your so detailed report. But unfortunately I can't find any clue related to this network interface status problem. Sorry for that. Maybe other guy can add more comments. At this moment, I suspect the link of em1.311 and probably its underlying interface em1 went down occasionally and came up in a short time. Is it possible? You could check the system log '/var/log/messages' to find related messages. > Thanks for your input Mark. > At the moment all is well again with the host; anyway I'm going to > give a long explanation of what I did below and so possible reasons > for that situation. > There is also feed for developers answers in that ... > > I cannot connect at the moment to the host to cut and paste in text > but I have access to java console and here is a screenshot containing > the line you requested (captured now that all is ok and host up and > runnign with two VMs): > > https://docs.google.com/file/d/0BwoPbcrMv8mvdmdIMUxTRVRVUzg/edit?usp=sharing > > Which fields are expected to be indicators of problems, as I had yesterday?

Hello, is there any bugzilla tracked for this? At my part I openend https://bugzilla.redhat.com/show_bug.cgi?id=947255 because with some servers I have also the problem that I'm put into a dracut shell with kernel higher than stock f18 initial one. Are there other ones? Anyone already tried latest kernels such as 3.8.5-201.fc18.x86_64? What is the kernel shipped with ovirt-node iso? Can we use it eventually on a standard fedora 18 system? BTW: with my home pc where I have model name : AMD Athlon(tm) II X4 630 Processor and an all-in-one 3.2.1 installation over fedora 18, I have no problems with 3.8.5-201.fc18.x86_64 kernel. Thanks, Gianluca

[Users] ovirt and web portals favicon
by Gianluca Cecchi 11 Apr '13

11 Apr '13

Hello, not a big deal, but could ovirt have its own logo and so map it to the favicon on portals? At the moment I see the well known Red Hat logo.... fedora has its own even if sponsored by Red Hat as I imagine oVirt is... Just for knowledge, not debate... PS: at the moment it seems the ovirt.org has no favicon, so it could be the occasion to make both... Thanks, Gianluca

[Users] VM crashes and doesn't recover
by Limor Gavish 10 Apr '13

10 Apr '13

Hello, I am using Ovirt 3.2 on Fedora 18: [wil@bufferoverflow ~]$ rpm -q vdsm vdsm-4.10.3-7.fc18.x86_64 (the engine is built from sources). I seem to have hit this bug: https://bugzilla.redhat.com/show_bug.cgi?id=922515 in the following configuration: Single host (no migrations) Created a VM, installed an OS inside (Fedora18) stopped the VM. created template from it. Created an additional VM from the template using thin provision. Started the second VM. in addition to the errors in the logs the storage domains (both data and ISO) crashed, i.e went to "unknown" and "inactive" states respectively. (see the attached engine.log) I attached the VDSM and engine logs. is there a way to work around this problem? It happens repeatedly. Yuval Meir

When using a Fedora with Firefox client to access an Ovirt vm, any ideas on how to avoid having to enter root password for the Fedora client when utilizing a local usb device via pass-through?

Hello, what is the status of support for spice console with ie9 (32bit on win7 32bit in my case) and 3.2 final? I have a windows xp vm but when I try to login to console from win7+ie9 I don't get any activex request to install.... ie exact version: https://docs.google.com/file/d/0BwoPbcrMv8mvVHZhYnczY3lKaTA/edit?usp=sharing If after a few minutes I click again on console button I get Error: A Request to the Server failed with the following Status Code: 400 Tried with both admin and user portal.
