ovirt 4.0.6 - live disk migration fails
by Maton, Brett 24 Nov '16

24 Nov '16

If I try to migrate a disk of a running VM to another storage domain it fails with the following message: Operation Cancelled Error while executing action: User is not logged in. Migrating disks of stopped VM's continues to work. Probably a bug ?

Storage questions
by Oscar Segarra 24 Nov '16

24 Nov '16

Hi, I'm planning to deploy a scalable VDI infraestructure where each phisical host can run over 100 VDIs and I'd like to deploy 10 physical hosts (1000 VDIs). In order to avoid performance problems (replicating 1000VDIs changes over gluster network I think can provoque performance problems) I have thought to use local storage for VDI assuming that VDIs cannot be migrated between phisical hosts. ¿Is my worry founded in terms of performance? ¿Is it possible to utilize local SSD storage for VDIs? I'd like to configure a gluster volume for backup on rotational disks (tiered+replica 2+ stripe=2) just to provide HA if a physical host fails. ¿Is it possible to use rsync for backing up VDIs? If not ¿How can I sync/backup the VDIs running on local storage on the gluster shared storage? If a physical host fails ¿How can I start the latest backup of the VDI on the shared gluster? Thanks a lot

Recommended Ovirt Implementation on Active-Active Datacenters (Site 1 and Site2) - Same Cluster
by Rogério Ceni Coelho 24 Nov '16

24 Nov '16

Hi Ovirt Jedi´s !!! First of all, congrats about the product !!! I love Ovirt !!! I am using Ovirt 4.0.4 with 10 hosts and 58 virtual machines on two Active-Active Datacenters using two EMC Vplex + two EMC VNX5500 + eight Dell Blades + 8 Dell PowerEdge M610 and two M620 Servers. Half servers are on Site 1 and Half servers on Site 2. The same with VMs. All Sites work as one and have redundant network, storage, power, etc etc etc ... I want to know what is the best way to set that VM number 1 runs on Site 1 and VM number 2 runs on Site 2 ? On Vmware 5.1 we use DRS Group Manager and on Hyper-V we use Custom Properties on hosts and on VMs. What we use on oVirt without segregate on two different Datacenters or two different clusters ? Thanks in advance.

Hi, I upgraded my engine host from 4.0.2.7 to 4.0.4 and when I attempt to login via a aaa provider I get: java.security.cert.CertificateExpiredException: NotAfter: Fri Nov 04 00:19:18 GMT 2016, What certificate is this referring to? The certificate from the aaa provider expires in 2063. It was fine until the upgrade. Thanks for any help, Cam

GFS2 and OCFS2 for Shared Storage
by Fernando Frediani 23 Nov '16

23 Nov '16

Has anyone managed to use GFS2 or OCFS2 for Shared Block Storage between hosts ? How scalable was it and which of the two work better ? Using traditional CLVM is far from good starting because of the lack of Thinprovision so I'm willing to consider either of the Filesystems. Thanks Fernando

OVN Provider setup issues
by Andrea Fagiani 23 Nov '16

23 Nov '16

Hi all, I've been messing around with the ovirt-ovn-provider [1] and I've run into some issues during the initial setup. I have a 5-node cluster (running the hosted-engine VA), LEGACY virtual switch; this test was done on a single host. Following the instructions from the aforementioned blog post, I have downloaded the ovirt-provider-ovn and ovirt-provider-ovn-driver rpms, and built the rpm packages for: - openvswitch (2.6.90) - openvswitch-ovn-common - openvswitch-ovn-host - openvswitch-ovn-central - python-openvswitch I set up a dedicated VM for the OVN controller, installed ovs and ovn-central, started the ovn-northd and ovirt-provider-ovn services. So far so good. I then moved on to the oVirt host and installed the above packages (minus ovn-central) as well as the ovirt-provider-ovn-driver provided, started the ovn-controller service and ran # vdsm-tool ovn-config <ovn controller IP> <host management IP> Executing the suggested checks I noticed that something didn't quite go as planned. Below is the /var/log/openvswitch/ovn-controller.log from the host machine. There are no firewalls involved (not even on the servers) and I also tried disabling SELinux but to no avail. Any ideas? Thanks, Andrea [1] http://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ 2016-11-07T14:22:09.552Z|00001|vlog|INFO|opened log file /var/log/openvswitch/ovn-controller.log 2016-11-07T14:22:09.553Z|00002|reconnect|INFO|unix:/var/run/openvswitch/db.sock: connecting... 2016-11-07T14:22:09.553Z|00003|reconnect|INFO|unix:/var/run/openvswitch/db.sock: connected 2016-11-07T14:22:09.555Z|00004|reconnect|INFO|tcp:10.100.248.11:6642: connecting... 2016-11-07T14:22:09.555Z|00005|reconnect|INFO|tcp:10.100.248.11:6642: connected 2016-11-07T14:22:09.556Z|00006|ofctrl|INFO|unix:/var/run/openvswitch/br-int.mgmt: connecting to switch 2016-11-07T14:22:09.556Z|00007|rconn|INFO|unix:/var/run/openvswitch/br-int.mgmt: connecting... 2016-11-07T14:22:09.557Z|00008|pinctrl|INFO|unix:/var/run/openvswitch/br-int.mgmt: connecting to switch 2016-11-07T14:22:09.557Z|00009|rconn|INFO|unix:/var/run/openvswitch/br-int.mgmt: connecting... 2016-11-07T14:22:09.557Z|00010|rconn|INFO|unix:/var/run/openvswitch/br-int.mgmt: connected 2016-11-07T14:22:09.557Z|00011|rconn|INFO|unix:/var/run/openvswitch/br-int.mgmt: connected 2016-11-07T14:22:09.558Z|00012|ofctrl|INFO|OpenFlow error: OFPT_ERROR (OF1.3) (xid=0x9): OFPBMC_BAD_FIELD OFPT_FLOW_MOD (OF1.3) (xid=0x9): (***truncated to 64 bytes from 240***) 00000000 04 0e 00 f0 00 00 00 09-00 00 00 00 00 00 00 00 |................| 00000010 00 00 00 00 00 00 00 00-22 00 00 00 00 00 00 00 |........".......| 00000020 ff ff ff ff ff ff ff ff-ff ff ff ff 00 00 00 00 |................| 00000030 00 01 00 04 00 00 00 00-00 04 00 b8 00 00 00 00 |................|

Cloning a VM with Ceph/Cinder based disk leaves disk in locked state
by Thomas Klute 22 Nov '16

22 Nov '16

Dear oVirt Users, we're using cinder (based on the Kolla setup) to provide storage for ovirt. Everything works fine except the clone process of a VM. Cloning a VM with NFS based storage works as expected, thus I think it's the cinder integration that causes the problem here. When cloning a VM with cinder/ceph-based storage we see, that the VM clone is created, the attached image is cloned as well, but the disk/image remains in locked state. We then need to issue a "update images set imagestatus=1 where imagestatus=2;" on the engine to make the VM clone work. Is this a bug in the cinder integration? Thanks and best regards, Thomas engine.log: 2016-11-21 10:00:20,216 INFO [org.ovirt.engine.core.bll.CloneVmCommand] (default task-19) [2dd83801] Lock Acquired to object 'EngineLock:{exclusiveLocks='[vm-vertr-kp-klon=<VM_NAME, ACTION_TYPE_FAILED_OBJECT_LOCKED>]', sharedLocks='[897d96c8-0ea9-4d06-b815-66a42b63c49b=<VM, ACTION_TYPE_FAILED_VM_IS_BEING_CLONED>, e5e06033-e099-4efe-a5cd-9de2ebc0238b=<DISK, ACTION_TYPE_FAILED_DISK_IS_USED_FOR_CREATE_VM$VmName vm-vertr-kp-klon>]'}' 2016-11-21 10:00:21,290 INFO [org.ovirt.engine.core.bll.CloneVmCommand] (default task-19) [] Running command: CloneVmCommand internal: false.

engine-setup failed on master on Centos 7
by Martin Perina 22 Nov '16

22 Nov '16

Hi, if you have recently tried to install master engine on Centos 7, you may have encountered following error during engine-setup: Failed to execute stage 'Misc configuration': Command '/usr/bin/ovirt-aaa-jdbc-tool' failed to execute This is currently tracked by [1] and it's caused by faulty slfj4 1.7.10 package in virt7-ovirt-common-candidate repository. We have untagged faulty package from the repository, but to fix the error you need to downgrade package version to slf4j 1.7.4 provided by Centos [2]. Sorry for inconvenience Martin Perina [1] https://bugzilla.redhat.com/show_bug.cgi?id=1394656 [2] http://mirror.centos.org/centos/7/os/x86_64/Packages/slf4j-1.7.4-3.el7.noar…

Hi, I have deployed a CENTOS 7.2 server in oVirt infraestructure (vdicmysql01) and I want to connect the console session using SPICE from my Windows 10 client. I have installed Remote Viewer but when I click on the console icon on the VMs: [image: Imágenes integradas 3] It downloads the .vv file and it launches the console: [image: Imágenes integradas 4] But keyboard does not work and I cannot interact with machine. I have also tried to connect from users portal but It does not appear: [image: Imágenes integradas 5] Anybody has experienced the same behaviour? Thanks a lot.

Hello friends. After I have updated one host with "yum update -y", I have this message and the host fails to connect to storage server (ISO type) (other host not updated yet are working fine): Thread-25::WARNING::2016-11-21 17:26:18,152::lvm::376::Storage.LVM::(_reloadvgs) lvm vgs failed: 5 [] [' WARNING: lvmetad is running but disabled.

I currently have two different ovirt installation: Ovirt3: 7 hosts linked to Compellent iscsi storage running ovirt 3.5.6 Ovirt4: 4 hosts linked to (same) Compellent iscsi storage running ovirt 4.0= .4 I'm currently moving my guests from ovirt3 to ovirt4. Since iscsi storage is linked to both installations, my high level approach= is: 1) Shutdown VM in ovirt3. 2) Maintenance + detach + remove VM storage in ovirt3 3) Change LUN mapping via iscsi storage manager from ovirt3 to ovirt4 4) Import storage in ovirt4 5) Import VM in ovirt4 6) Run and cheers with high grade liquor. GOTO step 1 for different VM= . Now, as soon as I perform step 3 (remove mappings from LUN), ovirt3 goes cr= azy and eventually forces me to reboot all hosts one by one. I tried different low level approaches to unmap LUN mpath'ed from hosts wit= h inconsistent results. A notable error log extract is: Nov 8 15:30:52 sovana vdsm root ERROR Process failed with rc=3D1 out=3D'\n= udevadm settle - timeout of 5 seconds reached, the event queue contains:\n = /sys/devices/virtual/block/dm-39 (8603)\n /sys/devices/virtual/block/dm-3= 9 (8604)\n /sys /devices/virtual/block/dm-39 (8605)\n /sys/devices/virtual/block/dm-39 (86= 06)\n /sys/devices/virtual/block/dm-39 (8607)\n /sys/devices/virtual/bloc= k/dm-39 (8608)\n /sys/devices/virtual/block/dm-39 (8609)\n /sys/devices/v= irtual/block /dm-39 (8610)\n /sys/devices/virtual/block/dm-39 (8611)\n /sys/devices/vi= rtual/block/dm-39 (8612)\n /sys/devices/virtual/block/dm-39 (8613)\n /sys= /devices/virtual/block/dm-39 (8614)\n /sys/devices/virtual/block/dm-39 (86= 15)\n /sys/ devices/virtual/block/dm-39 (8616)\n /sys/devices/virtual/block/dm-39 (861= 7)\n /sys/devices/virtual/block/dm-39 (8618)\n /sys/devices/virtual/block= /dm-39 (8619)\n /sys/devices/virtual/block/dm-39 (8620)\n /sys/devices/vi= rtual/block/ dm-39 (8621)\n /sys/devices/virtual/block/dm-39 (8622)\n /sys/devices/vir= tual/block/dm-39 (8623)\n /sys/devices/virtual/block/dm-39 (8624)\n /sys/= devices/virtual/block/dm-39 (8625)\n /sys/devices/virtual/block/dm-39 (862= 6)\n /sys/d evices/virtual/block/dm-39 (8627)\n /sys/devices/virtual/block/dm-39 (8628= )\n /sys/devices/virtual/block/dm-39 (8629)\n /sys/devices/virtual/block/= dm-39 (8630)\n /sys/devices/virtual/block/dm-39 (8631)\n /sys/devices/vir= tual/block/d m-39 (8632)\n /sys/devices/virtual/block/dm-39 (8633)\n /sys/devices/virt= ual/block/dm-39 (8634)\n /sys/devices/virtual/block/dm-39 (8635)\n /sys/d= evices/virtual/block/dm-39 (8636)\n /sys/devices/virtual/block/dm-39 (8637= )\n /sys/de vices/virtual/block/dm-39 (8638)\n /sys/devices/virtual/block/dm-39 (8639)= \n /sys/devices/virtual/block/dm-39 (8640)\n /sys/devices/virtual/block/d= m-39 (8641)\n /sys/devices/virtual/block/dm-39 (8642)\n /sys/devices/virt= ual/block/dm -39 (8643)\n /sys/devices/virtual/block/dm-39 (8644)\n /sys/devices/virtu= al/block/dm-39 (8645)\n /sys/devices/virtual/block/dm-39 (8646)\n /sys/de= vices/virtual/block/d I really need your help to sort this out as I'm actually blocked in my task= .

Could not get access to ACL tech driver 'ebiptables'
by Kenneth Bingham 21 Nov '16

21 Nov '16

I imported a guest from its iscsi storage domain and clicked the green UP button, but the guest failed to start. This was the first time vdsm tried to create a temporary storage domain for a host other than hosted_engine. I'm using the same chap credential that was used with the same iscsi storage domain with the old instance of Manager. It looks like it wasn't able to get permission to do something, but everything was set up with sudo-as-root. I used CentOS 7.2 with the ovirt-release repository and hosted-engine script to deploy Manager. >From /var/log/vdsm/vdsm.log on the host where it tried to start: Thread-23385::ERROR::2016-11-19 02:12:41,907::vm::765::virt.vm::(_startUnderlyingVm) vmId=`c3125d32-ae2a-4d2f-af4c-13661d90ddf9`::*The vm start process failed* Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 706, in _startUnderlyingVm self._run() File "/usr/share/vdsm/virt/vm.py", line 1996, in _run self._connection.createXML(domxml, flags), File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 123, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 917, in wrapper return func(inst, *args, **kwargs) File "*/usr/lib64/python2.7/site-packages/libvirt.py*", line 3611, in *createXML* if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: internal error: *Could not get access to ACL tech driver 'ebiptables'* >From /usr/lib64/python2.7/site-packages/libvirt.py which raised the error: def createXML(self, xmlDesc, flags=0): """Launch a new guest domain, based on an XML description similar to the one returned by virDomainGetXMLDesc() This function may require privileged access to the hypervisor.

Unexpected behaviour during creating VM using oVirt API
by Roman Chukov 20 Nov '16

20 Nov '16

Hello, I am trying to create a virtual machine from a template using oVirt API. Somehow like this: --- def createVM(connection, cluster, vmname, vmtemplate): try: param = params.VM( name=vmname, \ cluster=connection.clusters.get(name=cluster), \ template=connection.templates.get(name=vmtemplate), \ use_latest_template_version = True ) except: print "Could not construct a request to oVirtapi,please check parameters which were being sent to" return None try: connection.vms.add(param) except: print "I was not able to commit my request into oVirt api." return None return "OK" --- Everything is fine when I have only ONE version of a template. But I am used to create several number of versions for one template because it is quite flexible. In this case, when I run my script, I receive an "AmbiguousQueryError" error even if an option "use_latest_template_version = True" is used. I revised file /usr/lib/python2.7/site-packages/ovirtsdk/utils/filterhelper.py and found near line 30 that this error is raised unquestionably: -- if len(result) > 1: raise AmbiguousQueryError(query) return result[0] if result else None -- It seems quite strange. Either I do not understand the meaning of option "use_latest_template_version" or using of this option does not make sense, I mean query constructed in params.VM() function will not be passed by filterhelper.py in current implementation. I made a small patch that allows me to use the latest version of the template during VM creation: -- if len(result) > 1 : result = result[len(result) - 1] return result #raise AmbiguousQueryError(query) return result[0] if result else Nonepython-2.7.5-34.el7.x86_64 -- But I am still not sure that original behaviour of filehelper.py is unexpectable. I would be very pleasant if you explain me this issue. My OS is CentOS 7. I use Python python-2.7.5-34.el7.x86_64. Version of ovirt-engine-sdk is ovirt-engine-sdk-python-3.6.8.0-1.el7.centos.noarch -- Thanks in advance, Roman A. Chukov. https://asgardahost.org

oVirt 4.0.5 and SHE console from gui
by Gianluca Cecchi 20 Nov '16

20 Nov '16

Hello, In a clean environment configured in 4.0.5 I used VNC for hosted engine VM console during setup. In web admin gui I see that the graphics protocol for the Hosted Engine VM is indeed VNC and Video Type VGA. I have verified that if I configure a VM with VNC graphics (video type both cirrus and vga tried) I'm able to connect to it with remote-viewer from Linux client and with virt-viewer in a W2012 client. A part from the usual command hosted-engine --add-console-password and related vmcviewer one from console, can I connect to the VNC engine console also from web admin gui? Both from Windows and Linux I get error Unable to connect to the graphic server C:\Users\Admini~1\Appdata\Local\Temp\console-12.vv Unable to connect to the graphic server /tmp/mozilla_g.cecchi0/console.vv Can I setup console to spice after install? And in case can I connect to its console from webadmin gui then? Thanks, Gianluca

Multiple Data Storage Domains

--Apple-Mail=_6EA3CA6C-F1CA-43B1-A0ED-5EC9B2DD6690 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 I am having an issue in a Hosted Engine GlusterFS setup. I have 4 = hosts in a cluster, with the Engined being hosted on the Cluster. This = follows the pattern shown in the docs for a glusterized setup, except = that I have 4 hosts. I have engine, data, iso and export storage = domains all as glusterfs on a replica 3 glusterfs on the first 3 hosts. = These gluster volumes are running on an SSD Hardware Raid 6, which is = identical on all the hosts. All the hosts have a second Raid 6 Array = with Physical Hard Drives and I have created a second data storage = domain as a glusterfs across all 4 hosts as a stripe 2 replica 2 and = have added it to the Data Center.

Once the vm becomes non-responsive it cannot be stopped, removed or = destroyed without restarting the host machine that the VM is currently = running on. The 4 hosts are connected via 10gig ethernet, so should = not be a network issue. Any ideas?

Hi, I don't understand why, but after creating a new storage pool, I have been able to attach the engine to the datacenter.

Storage domain for Engine does not appear
by Oscar Segarra 19 Nov '16

19 Nov '16

Hi, I have created a 3 node gluster (replica 3) and I have made a fresh install of the ovirt engine (4.0.5.5-1). The install process has finishes successfuly but when I connect the ovirt engine the storage domain where Engine lives does not appear. If I try to import it, I'm able to make it appear but i cannot attach it to a Data Center. Has anyone experienced this issue? Thanks a lot.
