So starting with the OVirt mailing list. We are using OVirt with FC20 nodes with enabled virt-preview. Thus we are running qemu 2.1.2. Everything is working smoothly including live merge. For testing purposes we compiled qemu 2.1.3 from Fedora koji and updated one of the hosts. Trying to migrate a running VM to the new host fails with the message Unknown savevm section or instance 'kvm-tpr-opt' 0 I guess some incompatibility between the versions. But qemu git history between 2.1.2 and 2.1.3 gives no hints about the reason. Any ideas - or is that migration scenario not supported at all?

status of ovirt 3.5.1 with centos 7.1
by Jason Keltz 15 May '15

15 May '15

Hi. I wanted to check on the status of ovirt 3.5.1 with CentOS 7.1. I'm pretty sure the current 3.5.1 engine has problems with CentOS 7.1 (?), but not sure about vdsm? I know that 3.5.2 will resolve issues with engine... (I'm asking because I've kickstarted CentOS 7.1 as a host, and am having a few problems (eg. unable to talk to power management) and want to avoid debugging if it's already known to be broken... :) Thanks! Jason.

Problems with installing second host with hosted engine
by Tigran Baluyan 15 May '15

15 May '15

Hi, I've stumbled across a very strange bug and been trying to work around it for a couple of days with no luck. So my setup is: Host 1: centos 6.6 with ovirt 3.5 deployed as hosted engine. Had a few problems while deploying it, but eventually got it up and running. Host 2: same centos 6.6, same hardware. While executing hosted-engine --deploy, I am getting this error: [ INFO ] Stage: Setup validation [WARNING] Host name hyp-A2 has no domain suffix [WARNING] Failed to resolve hyp-A2 using DNS, it can be resolved only locally [ ERROR ] Failed to execute stage 'Setup validation': [Errno 2] No such file or directory: '/rhev/data-center/mnt/192.168.1.59: _media_ssd__raid10_ovirt_data__fast/f617dfce-4ac8-495b-a0f3-4f85ce39df27/ha_agent/hosted-engine.metadata' My storage machine is a separate host running RHEL 6.4. /etc/exports looks like this: /media/ssd_raid10/ *(rw,sync,all_squash) /media/ssd_raid10/ovirt *(rw,sync,no_subtree_check,anonuid=36,anongid=36,all_squash) *some other shares* Now here is the strange part: after repeatedly bashing my head against the wall I finally noticed the difference: on the first host it mounts as: 192.168.1.59:/media/ssd_raid10/ovirt/data_fast on /rhev/data-center/mnt/192.168.1.59:_media_ssd__raid10_ovirt_data__fast_ While on the second host it mounts as: 192.168.1.59:/media/ssd_raid10/ovirt/data_fast on /rhev/data-center/mnt/192.168.1.59:_media_ssd__raid10_ovirt_data__fast (note the lack of underscore in the end) That is what caused the problem - this "hosted-engine.metadata" file is actually a symlink. And because of different mount points on the second host it was pointing to nowhere. So I figured, maybe I should add / to the end of the nfs path. So I tried it like this: Please specify the storage you would like to use (iscsi, nfs3, nfs4)[nfs3]: Please specify the full shared storage connection path to use (example: host:/path): 192.168.1.59:/media/ssd_raid10/ovirt/data_fast/ [ INFO ] Installing on first host Please provide storage domain name. [hosted_storage]: As you can see, in this case it doesn't detect that it already has a hosted engine installed. So, I'm out of ideas how to make it work. There is clearly something unstable in the installation scripts, but does anyone have any idea how to make it work? PS: Sorry for my crude English, not really a native speaker. Thanks, Tigran.

I am using ovirt-engine-sdk-java-3.5.0.5.jar According to the SDK API,I can delete a VM using : api.getVMs().get(vmName).getSnapshots().getById(snapshotId).delete(); But there is no way to fetch the snapshot ID of a particular snapshot. Or List<VMSnapshot> vmSnapshots =3D api.getVMs().get(vmName).getSnapshots().li= st(); for (VMSnapshot vmSnapshot : vmSnapshots) { if(vmSnapshot.getDescription() =3D=3D snapshotdescription){ vmSnapshot.delete(); } I cannot use the above snippet of code to delete a snapshot,but the multipl= e snapshots for a vm can be created with the same description. So is there a way to create a snapshot with a snapshot name assigned to it. SO that delete,restore opeartions can be performed based on the snapshot na= me . Thanks, Prashanth R --_000_04352BA62627804FA4254F7542A9CF375C77E45BAZFFEXMB04globa_ Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr= osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" xmlns=3D"http:= //www.w3.org/TR/REC-html40"> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3Dus-ascii"= > <meta name=3D"Generator" content=3D"Microsoft Word 14 (filtered medium)"> <style></style> </head> <body lang=3D"EN-US" link=3D"blue" vlink=3D"purple"> <div class=3D"WordSection1"> <p class=3D"MsoNormal">Hi All,<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">I am facing issue in deleting a VM snapshot.<o:p></o= :p></p> <p class=3D"MsoNormal">I am using ovirt-engine-sdk-java-3.5.0.5.jar <o:p></= o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">According to the SDK API,I can delete a VM using :<o= :p></o:p></p> <p class=3D"MsoNormal">api.getVMs().get(vmName).getSnapshots().getById(snap= shotId).delete();<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">But there is no way to fetch the snapshot ID of a pa= rticular snapshot.<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal" style=3D"text-autospace:none">Or <o:p></o:p></p> <p class=3D"MsoNormal" style=3D"text-autospace:none"><o:p> </o:p></p> <p class=3D"MsoNormal" style=3D"text-autospace:none"><span style=3D"font-si= ze:10.0pt;font-family:Consolas;color:black">List<VMSnapshot> vmSnapsh= ots =3D api.getVMs().get(vmName).getSnapshots().list();</span><span style= =3D"font-size:10.0pt;font-family:Consolas"><o:p></o:p></span></p> <p class=3D"MsoNormal" style=3D"text-autospace:none"><span style=3D"font-si= ze:10.0pt;font-family:Consolas;color:black">     </span><b><span style=3D"font-size:10.0pt;font-family:Consolas;color:#7F005= 5">for</span></b><span style=3D"font-size:10.0pt;font-family:Consolas;color= :black"> (VMSnapshot vmSnapshot : vmSnapshots) {</span><span style=3D"font-= size:10.0pt;font-family:Consolas"><o:p></o:p></span></p> <p class=3D"MsoNormal" style=3D"text-autospace:none"><span style=3D"font-si= ze:10.0pt;font-family:Consolas;color:black">      </span><b><span style=3D"font-size:10.0pt;font-family:Consolas;color:#7F005= 5">if</span></b><span style=3D"font-size:10.0pt;font-family:Consolas;color:= black">(vmSnapshot.getDescription() =3D=3D <u>snapshotdescription</u>){</span><span style=3D"font-size:10.0pt;font-fam= ily:Consolas"><o:p></o:p></span></p> <p class=3D"MsoNormal" style=3D"text-autospace:none"><span style=3D"font-si= ze:10.0pt;font-family:Consolas;color:black">     &= nbsp;   vmSnapshot.delete();</span><span style=3D"font-size:10.0p= t;font-family:Consolas"><o:p></o:p></span></p> <p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:Consolas= ;color:black">      }</span><o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">I cannot use the above snippet of code to delete a s= napshot,but the multiple snapshots for a vm can be created with the same de= scription.<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">So is there a way to create a snapshot with a snapsh= ot name assigned to it.<o:p></o:p></p> <p class=3D"MsoNormal">SO that delete,restore opeartions can be performed b= ased on the snapshot name .<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> <p class=3D"MsoNormal">Thanks,<o:p></o:p></p> <p class=3D"MsoNormal">Prashanth R<o:p></o:p></p> <p class=3D"MsoNormal"><o:p> </o:p></p> </div> </body> </html> --_000_04352BA62627804FA4254F7542A9CF375C77E45BAZFFEXMB04globa_--

HE setup failing: Cannot set temporary password for console connection
by Daniel Helgenberger 13 May '15

13 May '15

Hello, a week ago I set up a HE (3.5.2) with no problems; now this fails. I suspect storage trouble but cannot pinpoint it. Did someth. change there with the recent async release? The storage domain is NFS3 via a 1G link to a ZFS storage appliance. The export is working quite fast; tested with iozone running for over 24h without problems. It starts with the "Verifying sanlock lockspace initialization" phase; which lasts about 7min (!). In the end it seems sanlock is locking the domain down. I can only get it back by stopping sanlock and vdsm. Attached is the full vdsm lock. Thanks! vdsm: Thread-27::ERROR::2015-05-12 19:17:51,470::domainMonitor::256::Storage.DomainMonitorThread::(_monitorDomain) Error while collecting domain 2f83ea82-e110-465d-a2a6-ac30534a9f6a monitoring information Traceback (most recent call last): File "/usr/share/vdsm/storage/domainMonitor.py", line 232, in _monitorDomain self.domain.selftest() File "/usr/share/vdsm/storage/sdc.py", line 49, in __getattr__ return getattr(self.getRealDomain(), attrName) File "/usr/share/vdsm/storage/sdc.py", line 52, in getRealDomain return self._cache._realProduce(self._sdUUID) File "/usr/share/vdsm/storage/sdc.py", line 122, in _realProduce domain = self._findDomain(sdUUID) File "/usr/share/vdsm/storage/sdc.py", line 141, in _findDomain dom = findMethod(sdUUID) File "/usr/share/vdsm/storage/nfsSD.py", line 122, in findDomain return NfsStorageDomain(NfsStorageDomain.findDomainPath(sdUUID)) File "/usr/share/vdsm/storage/nfsSD.py", line 112, in findDomainPath raise se.StorageDomainDoesNotExist(sdUUID) StorageDomainDoesNotExist: Storage domain does not exist: ('2f83ea82-e110-465d-a2a6-ac30534a9f6a',) Detector thread::DEBUG::2015-05-12 19:24:33,163::BindingXMLRPC::1173::XmlDetector::(handleSocket) xml over http detected from ('127.0.0.1', 47076) Thread-93::DEBUG::2015-05-12 19:24:33,166::BindingXMLRPC::1133::vds::(wrapper) client [127.0.0.1]::call vmSetTicket with ('e3d350c5-6254-4908-99e9-d60ca2e046f7', '5435uOVP', '10800', 'disconnect', {}) {} Thread-93::ERROR::2015-05-12 19:24:33,166::BindingXMLRPC::1152::vds::(wrapper) unexpected error Traceback (most recent call last): File "/usr/share/vdsm/rpc/BindingXMLRPC.py", line 1136, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/rpc/BindingXMLRPC.py", line 383, in vmSetTicket return vm.setTicket(password, ttl, existingConnAction, params) File "/usr/share/vdsm/API.py", line 642, in setTicket return v.setTicket(password, ttl, existingConnAction, params) File "/usr/share/vdsm/virt/vm.py", line 4834, in setTicket graphics = _domParseStr(self._dom.XMLDesc(0)).childNodes[0]. \ AttributeError: 'NoneType' object has no attribute 'XMLDesc' and: Thread-91::DEBUG::2015-05-12 19:25:15,152::libvirtconnection::143::root::(wrapper) Unknown libvirterror: ecode: 38 edom: 42 level: 2 message: Failed to acquire lock: No space left on device Thread-91::DEBUG::2015-05-12 19:25:15,154::vm::2294::vm.Vm::(_startUnderlyingVm) vmId=`e3d350c5-6254-4908-99e9-d60ca2e046f7`::_ongoingCreations released Thread-91::ERROR::2015-05-12 19:25:15,154::vm::2331::vm.Vm::(_startUnderlyingVm) vmId=`e3d350c5-6254-4908-99e9-d60ca2e046f7`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 2271, in _startUnderlyingVm self._run() File "/usr/share/vdsm/virt/vm.py", line 3335, in _run self._connection.createXML(domxml, flags), File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 111, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3427, in createXML if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: Failed to acquire lock: No space left on device sanlock: 2015-05-12 19:11:27+0200 4338 [708]: s2 lockspace 2f83ea82-e110-465d-a2a6-ac30534a9f6a:1:/rhev/data-center/mnt/10.11.0.30:_volumes_ovirt_engine/2f83ea82-e110-465d-a2a6-ac30534a9f6a/dom_md/ids:0 2015-05-12 19:11:48+0200 4359 [702]: s2 host 1 1 4338 9f9fb274-9ae8-490e-bfba-72a743b0ebb2.hv01.sec.i 2015-05-12 19:11:48+0200 4359 [702]: s2 host 250 1 0 9f9fb274-9ae8-490e-bfba-72a743b0ebb2.hv01.sec.i 2015-05-12 19:11:48+0200 4359 [707]: s2:r2 resource 2f83ea82-e110-465d-a2a6-ac30534a9f6a:SDM:/rhev/data-center/mnt/10.11.0.30:_volumes_ovirt_engine/2f83ea82-e110-465d-a2a6-ac30534a9f6a/dom_md/leases:1048576 for 3,11,4167 2015-05-12 19:23:26+0200 5057 [708]: s3 lockspace 2f83ea82-e110-465d-a2a6-ac30534a9f6a:1:/rhev/data-center/mnt/10.11.0.30:_volumes_ovirt_engine/2f83ea82-e110-465d-a2a6-ac30534a9f6a/dom_md/ids:0 2015-05-12 19:23:48+0200 5079 [702]: s3 host 1 2 5058 9f9fb274-9ae8-490e-bfba-72a743b0ebb2.hv01.sec.i 2015-05-12 19:23:48+0200 5079 [702]: s3 host 250 1 0 9f9fb274-9ae8-490e-bfba-72a743b0ebb2.hv01.sec.i 2015-05-12 19:24:53+0200 5144 [702]: cmd 9 target pid 4893 not found 2015-05-12 19:25:14+0200 5165 [708]: r3 cmd_acquire 2,9,4893 invalid lockspace found -1 failed 0 name 2f83ea82-e110-465d-a2a6-ac30534a9f6a -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767
