Recently built a three host HCI with oVirt node 4.2.5. I am seeing the following error in each hosts syslog often. What does it mean and how can it be corrected? vdsm[3470]: ERROR Internal server error#012Traceback (most recent call last):#012 File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 606, in _handle_request#012 res = method(**params)#012 File "/usr/lib/python2.7/site-packages/vdsm/rpc/Bridge.py", line 197, in _dynamicMethod#012 result = fn(*methodArgs)#012 File "/usr/lib/python2.7/site-packages/vdsm/gluster/apiwrapper.py", line 91, in vdoVolumeList#012 return self._gluster.vdoVolumeList()#012 File "/usr/lib/python2.7/site-packages/vdsm/gluster/api.py", line 90, in wrapper#012 rv = func(*args, **kwargs)#012 File "/usr/lib/python2.7/site-packages/vdsm/gluster/api.py", line 818, in vdoVolumeList#012 status = self.svdsmProxy.glusterVdoVolumeList()#012 File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 55, in __call__#012 return callMethod()#012 File "/usr/lib/python2.7/site-packages/vdsm/common/supervdsm.py", line 53, in <lambda>#012 **kwargs)#012 File "<string>", line 2, in glusterVdoVolumeList#012 File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod#012 raise convert_to_error(kind, result)#012AttributeError: 'str' object has no attribute 'iteritems'

oVirt 4.2.6 + GlusterFS
by radu＠radu.cat 08 Aug '18

08 Aug '18

Hello, I have 24 HP DL360 G7 all with 64G RAM and 1TB SAS disks. What I want to archive is to use all the nodes with ovirt (one will be for the controller + iso domain) and use GluterFS in the same nodes for the storage domain. Idk if anyone tried it before, but I want it to replace my actual "standalone" production hypervisors schema. Thanks in advance

Failed to hot-plug disk
by Punaatua PK 08 Aug '18

08 Aug '18

Hello, I have a problem when i tried to hotplug a disk to a VM. Here is the situation. We use a VM (let's call this backupVM) which is responsible of doing our VM backup by : - Making a snapshot of the VM we want to backup - Attach the snapshot disk - Make the copy using DD - Unplug the snapshot disk and then delete snapshot. For some reason that i don't know, for certain VM, the backupVM cannot hot plug the snapshot disk. I'm using ovirt 4.2.4 Here is what is see in engine.log 2018-08-04 19:52:30,496-10 ERROR [org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand] (default task-61) [361eca85-ca85-4e23-b292-cd8303a1a86d] Command 'org.ovirt.engine.core.bll.storage.disk.AttachDiskToVmCommand' failed: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to HotPlugDiskVDS, error = internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock, code = 45 (Failed with error FailedToPlugDisk and code 45) Here is the vdsm.log 2018-08-04 19:51:38,512-1000 INFO (jsonrpc/5) [virt.vm] (vmId='78ef239f-3cb3-4eef-921f-f989724009ef') Hotplug disk xml: <?xml version='1.0' encoding='utf-8'?> <disk address="" device="disk" snapshot="no" type="file"> <source file="/var/lib/vdsm/transient/225ec856-d661-4374-bb7d-8ea7168fe5f2-b641bb09-325a-4932-a9af-32c907e4a381.D52Nkj" /> <target bus="virtio" dev="vdg" /> <serial>c312a0c3-8c58-472f-99ad-cfbabb42337d</serial> <driver cache="writethrough" error_policy="stop" io="threads" name="qemu" type="qcow2" /> </disk> (vm:3859) 2018-08-04 19:51:38,672-1000 ERROR (jsonrpc/5) [virt.vm] (vmId='78ef239f-3cb3-4eef-921f-f989724009ef') Hotplug failed (vm:3867) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 3865, in hotplugDisk self._dom.attachDevice(driveXml) File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 98, in f ret = attr(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 130, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 92, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 570, in attachDevice if ret == -1: raise libvirtError ('virDomainAttachDevice() failed', dom=self) libvirtError: internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock here is libvirtd log in /var/log/messages libvirtd: 2018-08-05 05:51:38.637+0000: 4967: error : qemuMonitorJSONCheckError:389 : internal error: unable to execute QEMU command 'device_add': Failed to get shared "write" lock Do you guys have any idea of what going on ?

VirtIO in new upgraded 4.2.5 for FreeBSD is very poor (could not use)
by Paul.LKW 08 Aug '18

08 Aug '18

Dear All: I just upgraded my oVIrt-4.2.4 to 4.2.5 and nightmare begin, FreeBSD VMs hangs once the VM's VirtIO harddisk is some loading (eg. extracting a big tar ball, portsnap extract, etc.), I tried to create a VMs using back the IDE do not has any problem but got slow IO performance once using VirtIO it will hang as it like. I also tried to create another VMs with VirtIO-SCSI it seems the hang problem no occur but I got the oVirt-Host loading over 40 when VM harddisk have some little job, so conclusion is if you guys will using FreeBSD as guest please do not upgrade at the moment. In fact I feel every time the new version always have problem and causing user to nightmare. BR, Paul.LKW

Space in entity names (VM and Network) in oVirt
by Hari Prasanth Loganathan 08 Aug '18

08 Aug '18

Hi Team, I have VM's and Network's in oVirt with space in the name. How can I perform an exact search for the following name *Name1*: Aug X X *Name2*: Aug X X X 1) I try to search with space in the name, It is not working. https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug X X It is not returning any result. 2) I try to search with encoded value for space in the name, It is not working. (encoded value for space is %20) https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug%20X%20X 3) I try to search like below with '*' for space and end up getting both the values in response, https://172.30.60.42/ovirt-engine/api/networks?search=name%3DAug*X so what is the correct way to search the name with space ?

Re: Update to 4.2.5, Cant start VMs
by Vincent Royer 08 Aug '18

Indeed the Storage domains are via NFS served by Windows Server 2016. the workaround says "use NFSV3", I'm afraid this will break my existing installation. For now, all my VMs are running on one host that is still on 4.2.0.

Update to 4.2.5, Cant start VMs
by Vincent Royer 07 Aug '18

07 Aug '18

I updated the engine, and one of my nodes to 4.2.5. I'm attempting to re-start the VMs that were pinned to it, and migrate another VM to it so that I can update my other node. When I try to start the VMs that were pinned to the host, I get: VM Tuning3 is down with error. Exit message: XML error: Multiple 'scsi' > controllers with index '0'. To fix this I tried to detach the disk and re-attach it, no luck. When I try to migrate a running VM to this host, I get: Host Letty has network interface which exceeded the defined threshold [95%] > (bond0: transmit rate[0%], receive rate [97%]) The host I'm migrating FROM gets a similar error, and the VM does not migrate. I tried the different migration policies without any luck. I did successfully migrate the Hosted Engine to the new host, no errors. Thanks for any advice! Vincent

better understand ovirt-engine functions
by stuartk＠alleninstitute.org 07 Aug '18

07 Aug '18

I've been reading through documentation https://www.ovirt.org/documentation/architecture/architecture/ https://www.ovirt.org/documentation/self-hosted/Self-Hosted_Engine_Guide/ But am struggling still to understand the role ovirt-engine plays. Would anyone have recommends for additional reads? The problem I'm tackling currently looks like this: - We have (2) oVirt Data Centers, each populated by a single Cluster. The Data Centers are physically & network-wise 'distant' from one another - hosted-engine runs on (3) of the (4) Hosts in Data Center A / Cluster A. hosted-engine does not run on Data Center B / Cluster B - When we disrupt network connectivity around Cluster A (yes, that's Cluster *A*), Hosts in Cluster B crash (requiring a power cycle) and Guests in Cluster B get stopped and paused I'm struggling to understand why mussing with Cluster A affects Cluster B. From pcaps, I can see plenty of TLS traffic from Cluster A's Hosts -- presumably from ovirt-engine running on Cluster A -- exchanged with Cluster B. So, during my last maintenance window, I put hosted-engine into maintenance mode ... but Hosts/VMs in Cluster B were still affected. Where do I go to better understand what ovirt-engine does when it is 'managing' Hosts & VMs? --sk

Datacenter of several Hosts with Local Storage ? (share Logical Network)
by jeanbaptiste＠nfrance.com 07 Aug '18

07 Aug '18

Hello, My question is pretty simple :) Is there a way to configure Local(s) Storage Datacenter with more than 1 host ? The goal is is to share some Datacenter simple parameters between several hosts (with Local storage) like Logical Networks ? If it is not possible what is the best way / workaound to do this ? To compare, on Xenserver, it is possible to configure a "Pool" of some hosts which have Local Storage, but which share same Logical network configuration.. (I do not say XS is better^^, far from it !) Thanks for all :) Jean-Baptiste

MoM - Not working ? How to use it ?
by jeanbaptiste＠nfrance.com 07 Aug '18

07 Aug '18

Hello, I'm trying to test Memory balloon useful functionality, but l'm unable to make it work successfuly. Firstly, I enable the MOM on my Cluster: Memory Balloon Enable Memory Balloon Optimization Secondly, I configure a VM virtual machine like this: On system tab: Memory Size : 28672 MB Maximum memory : 28672 MB On Ressource allocation tab: Memory Allocation: Physical Memory Guaranteed : 2048 MB Memory Balloon Device: Enabled Thirdly, I test 1- I boot the VM. After boot VM consume 200MB 2- I lauch perl program which consume 26GB. 3- During this, Host RAM usage is near 90% 4- I stop the perl program, and on guest side, RAM usage drop down to 200Mo 5- On host side, RAM usage keep to 24 - 26GB. I wait some time to show if the qemu-vm process drop is host-ram-usage. Ram usage keep to 24GB. 6- I try to launch another VM like the first one (but with 8GB RAM and 2GB Guaranteed) , on the host (to "force" Mom ?) but I'm unable to lauch it, Host free mem is insufficient I change MoM log to debug to show something: 2018-07-31 11:49:31,887 - mom.RPCServer - INFO - ping() 2018-07-31 11:49:31,888 - mom.RPCServer - INFO - getStatistics() 2018-07-31 11:49:31,888 - mom.Monitor - DEBUG - Field 'mem_free' not known.

Tuning and testing GlusterFS performance
by Jayme 07 Aug '18

07 Aug '18

So I've finally completed my first HCI build using the below configuration: 3x Dell PowerEdge R720 2x 2.9 GHz 8 Core E5-2690 256GB RAM 2x250gb SSD Raid 1 (boot/os) 2x2TB SSD jbod passthrough (used for gluster bricks) 1Gbe Nic for management 10Gbe nic for Gluster Using Replica 3 with no arbiter. Installed the latest version of oVirt available at the time 4.2.5. Created recommended volumes (with an additional data volume on second SSD). Not using VDO First thing I did was setup glusterFS network on 10Gbe and set it to be used for glusterFS and migration traffic. I've setup a single test VM using Centos7 minimal on the default "x-large instance" profile. Within this VM if I do very basic write test using something like: dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync I'm seeing quite slow speeds, only 8mb/sec. If I do the same from one of the hosts gluster mounts i.e. host1: /rhev/data-center/mnt/glusterSD/HOST:data I get about 30mb/sec (which still seems fairly low?) Am I testing incorrectly here? Is there anything I should be tuning on the Gluster volumes to increase performance with SSDs? Where can I find out where the bottle neck is here, or is this expected performance of Gluster?

Unable to revive host after a reboot
by Julius Schwartzenberg 03 Aug '18

03 Aug '18

Hi, I recently had to shutdown my oVirt system which contains both the engine and the host. After it came back up, the host was not able to initialize anymore from the oVirt UI. First it kept getting stuck in a loop with setting "ExecutingStarted: Jul 30, 2018, 9:06:21 AMSetting Host pc331 to Non-Operational mode." This was being repeated over and over again. It also gave this error: Host pc331 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' Even though I am using that interface (ovirtmgmt) to access the system and 'ip addr show' shows that it's set up properly. I tried some more things, including upgrading the host, When I do that, the status changes to 'Installing' and later to 'Install Failed'. Here are the engine.log, vdsm.log and ovirt-host-deploy*.log: https://drive.google.com/open?id=13vIUDVjPynmAK0pnFRLabDfUlG1lmkpI https://drive.google.com/open?id=10Zm2dDpxM2k5A2bEs_l6gOv_yWv4cjlN https://drive.google.com/open?id=1AieWMzRuA0gZj3x5yDH1AGnsT2E3VtOM Any idea what is going wrong (what I'm doing wrong) and how to solve it? Thanks in advance! Best regards, Julius
