Confused by logical networks
by Paul-Erik Törrönen 25 Feb '18

25 Feb '18

I'm not sure how the logical networks should work and would appreciate if someone could shed some light into the matter, I've tried reading the documentation¹ but have not become any wiser :-/ For the sake of argument, I have two hosts in the same cluster/DC, They both have 2 network devices each (let's call them eth0 and eth1). On both hosts the ovirtmgmgt is connected to eth0 and uses the 10.0.0.0/8-network. Host 1 is 10.0.0.1 and host 2 is 10.0.0.2. All four network devices are connected to one switch. Then I create a logical network, mylogic which should be 192.168.1.0/24, which I assign to eth1 on each host, but define only for host 1 an ip-address, 192.168.1.1, host 2 has also the network assigned to eth1, but withouth an ip address. Next I create vm1 on host 1, give it a single virtual network connection to mylogic, and configure the guest to use 192.168.1.2 with gw 192.168.1.1. Obviously I can from the guest ping 192.168.1.1 which is the host address on the logical network as the guest is running on the same hardware where the host ip address is defined. However, and this is where my confusion lies, if I now create another vm, vm2, on host 2, attach its network device to the mylogic network and configure it to use 192.168.1.3 with gw 192.168.1.1, I can not ping neither 192.168.1.1 nor 192.168.1.2. My understanding is that vm2 should be able to ping the wm1 as well as the gateway address defined on host 1. However this does not seem to be the case. What have I missed here? TIA, Poltsi ¹ https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/

VM is locked, servlet , and SpiceVersion.txt problem
by Terry hey 24 Feb '18

24 Feb '18

Hello everyone! Thank for your time to analyize my problem. Totally, i have two question. I encountered vm image lock problem. The following action is what i have to and make the vm image locked. First, i imported a vm. Since it is take too long time to import and the engine.log always repeatly said it was waiting child command id. "2018-02-23 16:37:46,603+08 INFO [org.ovirt.engine.core.bll.ConcurrentChildCommandsExecutionCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-16) [1c44d543-4dcc-429d-a172-386cc860afe0] Command 'ImportVm' (id: '09718bd2-797d-4323-b1ad-1a85604543c3') waiting on child command id: '9e285b2d-c0c7-4a75-8c70-b619b45c6855' type:'CopyImageGroup' to complete " So,I thought the operation was not normal. So, 1. I use "./unlock_entity.sh" to unlock the virtual disk of the vm. 2. Virtual disk was unlocked but vm was still locked. Therefore, i use "./unlock_entity.sh" to show locked vm. But there was nothing. 3. Then i used "./taskcleaner.sh" to clean all task. But nothing happen. Q1: So, now, i would like to ask how to unlock the vm image so that i can delete or use it. Q2: In addition, there are two error or warning appeared in engine.log 1. 2018-02-23 09:57:19,495+08 WARN [org.ovirt.engine.core.utils.servlet.ServletUtils] (default task-272) [] File'/usr/share/ovirt-engine/ui-plugins/dashboard-resources/css/main-tab.d3769419.css' is 2839039 bytes long.

Do you guys have any idea what do they mean? I really appreciate you help. Thank you! Regards Terry

This is a multi-part message in MIME format. --------------3DF9AE3C9E55466CF85B4C9B Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hi, I could successfully upgrade our Ovirt Environment from 4.1.9 to 4.2.1, really great job with the new interface. Everything runs well so far, the only problem I have is when trying to Upgrade the Cluster Compatibility Level from 4.1 to 4.2 it throw an error : Error while executing action: Update of cluster compatibility version failed because there are VMs/Templates [spfy-tscon] with incorrect configuration. To fix the issue, please go to each of them, edit and press OK. If the save does not pass, fix the dialog validation. This VM is a Windows Server 2016 System with a custom property using smbios hook, could that be the problem? The engine log don't help a lot: /2018-02-22 18:49:42,026+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-57) [595850d5] EVENT_ID: CLUSTER_CANNOT_UPDATE_VM_COMPATIBILITY_VERSION(12,005), Cannot update compatibility version of Vm/Template: [spfy-tscon], Message: [No Message]// / Are there some other place to investigate and get some more information about this error?

rebooting hypervisors from time to time
by Erekle Magradze 23 Feb '18

23 Feb '18

Hello there, I am facing the following problem from time to time one of the hypervisor (there are 3 of them)s is rebooting, I am using ovirt-release42-4.2.1-1.el7.centos.noarch and glsuter as a storage backend (glusterfs-3.12.5-2.el7.x86_64). I am suspecting gluster because of the e.g. message bellow from one of the volumes, Could you please help and suggest to which direction should investigation go?

Installing Windows - no virtio-win.vfd as floppy option
by Geoff Sweet 23 Feb '18

23 Feb '18

Howdy all, I'm following this document: https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Windows_Virtu… To launch a couple Windows VM's. The document outlines that the virtio-win.vfd file is automatically installed into the ISO storage domain for the engine host. And that you can upload it to other ISO domains as needed. For the life of me, I can not find that file anywhere across any of my ovirt servers. For reference this is 4.2.0. Am I missing something obvious? Thanks for any help you can offer. -Geoff

Question about sanlock lockspaces
by Artem Tambovskiy 22 Feb '18

22 Feb '18

Hello, I'm still troubleshooting my cluster and trying to figure out which lockspaces should be present and which shouldn't. If HE VM is not running both ovirt-ha-agent and ovirt-ha-broker are down and storage disconnected by hosted-engine --disconnect-storage should I see something related to HE storage domain in sanlock client status output? For some reason on one host I don't see anything and the second one still reports about present lockspace for HE storage domain. Is this normal? [root@ovirt1 ~]# sanlock client status daemon b1d7fea2-e8a9-4645-b449-97702fc3808e.ovirt1.tel p -1 helper p -1 listener p -1 status p 3763 p 62861 quaggaVM p 63111 powerDNS p 107818 pjsip_freepbx_14 p 109092 revizorro_dev p 109589 routerVM s a40cc3a9-54d6-40fd-acee-525ef29c8ce3:2:/rhev/data-center/mnt/glusterSD/ ovirt2.telia.ru\:_data/a40cc3a9-54d6-40fd-acee-525ef29c8ce3/dom_md/ids:0 s 4a7f8717-9bb0-4d80-8016-498fa4b88162:1:/rhev/data-center/mnt/glusterSD/ ovirt2.telia.ru\:_engine/4a7f8717-9bb0-4d80-8016-498fa4b88162/dom_md/ids:0 r a40cc3a9-54d6-40fd-acee-525ef29c8ce3:SDM:/rhev/data-center/mnt/glusterSD/ ovirt2.telia.ru\:_data/a40cc3a9-54d6-40fd-acee-525ef29c8ce3/dom_md/leases:1048576:49 p 3763 As it looks to me lockspace 4a7f8717-9bb0-4d80-8016-498fa4b88162:1:/rhev/data-center/mnt/glusterSD/ ovirt2.telia.ru\:_engine/4a7f8717-9bb0-4d80-8016-498fa4b88162/dom_md/ids:0 shouldn't be present, and it doesn't match to the host_id, but may be I'm wrong here...
