trouble when creating VM snapshots including memory
by Matthias Leopold 12 Jun '17

12 Jun '17

hi, i'm having trouble creating VM snapshots that include memory in my oVirt 4.1 test environment. when i do this the VM gets paused and shortly (20-30s) afterwards i'm seeing messages in engine.log about both iSCSI storage domains (master storage domain and data storage where VM resides) experiencing high latency. this quickly worsens from the engines view: VM is unresponsive, Host is unresponsive, engine wants to fence the host (impossible because it's the only host in the test cluster). in the end there is an EngineException EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues (Failed with error VDS_NETWORK_ERROR and code 5022) the snapshot fails and is left in an inconsistent state. the situation has to be resolved manually with unlock_entity.sh and maybe lvm commands. this happened twice in exactly the same manner. VM snapshots without memory for this VM are not a problem. VM guest OS is CentOS7 installed from one of the ovirt-image-repository images. it has the oVirt guest agent running. what could be wrong? this is a test environment where lots of parameters aren't optimal but i never had problems like this before, nothing concerning network latency. iSCSI is on a FreeNAS box. CPU, RAM, ethernet (10GBit for storage) on all hosts involved (engine hosted externally, oVirt Node, storage) should be OK by far. it looks like some obvious configuration botch or performance bottleneck to me. can it be linked to the network roles (management and migration network are on a 1 GBit link)? i'm still new to this, not a lot of KVM experience, too. maybe someone recognizes the culprit... thx matthias

Re-adding oVirt host.
by Marcin M. Jessa 11 Jun '17

11 Jun '17

Hi guys. I have a two node setup. One server running on CentOS [1] and one server with oVirt node [2]. I added local storage to my oVirt host but I forgot the storage I chose was already in use so it failed. I then got a host entry with local storage which was shown as not configured. I then removed that local storage host but then it completely disappeared from my setup. Then I tried to add it again but oVirt said that host is already defined. I tried different name with the same IP but it also failed saying that that IP is already defined. Is there a way to re-add that previously defined host? How can I bring it back? [1]: oVirt Engine Version: 4.1.2.2-1.el7.centos [2]: oVirt Node 4.1.2 Marcin Jessa.

chrony or ntp ?
by Fabrice Bacchella 11 Jun '17

11 Jun '17

I haven't switched from ntp to chrony. So I have configured my puppet to remove it as it's now part of default installation of rhel. I works well with everything except on vdsm, since last upgrade: # yum erase chrony .. Removing for dependencies: vdsm x86_64 4.19.15-1.el7.centos @ovirt-4.1 2.6 M vdsm-hook-vmfex-dev noarch 4.19.15-1.el7.centos @ovirt-4.1 21 k Why vdsm depends on chrony ? Any time synchronisation solution is good. Is that the role of ovirt to chose for me ?

Hardware for Hyperconverged oVirt: Gluster storage best practice
by ovirt＠fateknollogee.com 11 Jun '17

11 Jun '17

Martin, Looking to test oVirt on real hardware (aka no nesting) Scenario # 1: 1x Supermicro 2027TR-HTRF 2U 4 node server I will install the o/s for each node on a SATADOM. Since each node will have 6x SSD for gluster storage. Should this be software RAID, hardware RAID or no RAID? Scenario # 2: 3x SuperMicro SC216E16-R1200LPB 2U server Each server has 24x 2.5" bays (front) + 2x 2.5" bays (rear) I will install the o/s on the drives using the rear bays (maybe RAID 1?) For Gluster, we will use the 24 front bays. Should this be software RAID, hardware RAID or no RAID? Thanks Femi

ovirt client developpement
by Fabrice Bacchella 11 Jun '17

11 Jun '17

For my ovirt cli, I would like to have unit tests. But there is nothing to test in standalone mode, I need a running ovirt with a database in a known state. Is there some where a docker images with a toy setup, or a mock ovirt engine that can be downloaded and used for that ?

nfs.home.lan already exits with uuid
by Greg Fitzgerald 09 Jun '17

09 Jun '17

Hi, I just replaced my local proxmox server with ovirt for some testing. When I woke up this morning one of my VM's nfs.home.lan was offline. So I tried to power it back on and I received following event message. VM nfs.home.lan is down with error. Exit message: operation failed: domain 'nfs.home.lan' already exists with uuid b6453519-4124-4a47-9fb8-064be743067d. I tried to reboot the physical machine, I also tried destroying the VM (keeping the disk drives) and recreating it and attaching the drive again. Always end up with the same error message. Best Regards, Greg Fitzgerald
