CpuProfileCreator
by cmc 07 Nov '16

07 Nov '16

Hi, I'm having problems creating VMs with the following error message: "User doesn't have permissions to assign the cpu profile" >From the log: 2016-11-03 12:26:36,918 WARN [org.ovirt.engine.core.bll.AddVmCommand] (default task-346) [] Validation of action 'AddVm' failed for user cam@fscfc.co.uk@fscfc.co.uk-authz.

When I go to Clusters->CpuProfile for this cluster, it does show all of these permissions. What am I doing wrong here? Thanks for any help, Cam

Problem creating ovirtmgmt bridge
by Chris Cowley 07 Nov '16

07 Nov '16

I am installing on a 3 node cluster, with gluster as my storage. Each node has a pair of bonds. At the moment, my intention is to use bond0 for all VM traffic, with management (and thus ovirtmgmt) on bond1 along with Gluster (bond1.<vlanid>. Sadly hosted-engine --deploy dies saying: ``` Failed to execute stage 'Misc configuration': Failed to setup networks {'ovirtmgmt': {'ipaddr': u'10.110.84.11', 'netmask': u'255.255.255.0', 'bonding': 'bond1', 'bootproto': u'none', 'gateway': u'10.110.84.1', 'defaultRoute': True}}. Error code: "-32603" message: "Attempt to call function: <bound method Global.setupNetworks of <API.Global object at 0x38e5050>> with arguments: ({u'ovirtmgmt': {u'ipaddr': u'10.110.84.11', u'bonding': u'bond1', u'netmask': u'255.255.255.0', u'bootproto': u'none', u'gateway': u'10.110.84.1', u'defaultRoute': True}}, {}, {u'connectivityCheck': False}) error: 'NoneType' object is not iterable" ``` Is my way of configuring my network even possible? Or do I need to re-think things

Ovirt 4.0.4 - Solaris 11u3 Guest - No networking
by Alfred Angelov 07 Nov '16

07 Nov '16

Hello all, I have browsed the list and found that this issue has been worked on back in 2013 in ovirt 3.4; and the fix was to add hook scripts that would remove the -cpu parameter before VM start. I tried all different (non-Virtio) network drivers with the same problem, the network does not work. Anyone got a workaround or guide how to create a working Solaris 11 guest inside ovirt? -- *Alfred Angelov* IT Manager www.foxt.com | alfred.angelov(a)foxt.com | +46 73 363 00 63 Connect with me on Linkedin <https://www.linkedin.com/in/alfredangelov>

external users problem
by Baptiste Agasse 07 Nov '16

07 Nov '16

Hi all, We use ovirt 4.0.4 with FreeIPA as external provider. The external provider was configured via the 'ovirt-engine-extension-aaa-ldap-setup' command. The authentication works fine, but in the webui, when you go on the 'Active User Sessions', all users uuid is showed as '00000000-0000-0000-0000-000000000000'. Other problem, maybe related, when a user create a VM, by default a permission is created with the role of 'UserVmManager'. On the 'Permissions' pane, we see a line with no value for User, Authorization provider, Namespace. The only value set on this line is the role (UserVmManager in that case). When we try to remove this line, an exception occurs in the webui that prevent deletion of this line. This behavior is verified on all our oVirt environments (oVirt 4.0.4 + FreeIPA) Someone hit the same problem ? Have a nice day. Regards. -- Baptiste AGASSE

Import of OVA fails in 4.0.4
by Derek Atkins 06 Nov '16

06 Nov '16

Hi, I just tried using the OVA import feature in 4.0.4 to import an OVA file created from VMware-Workstation-12. I packaged the OVA, got it onto my ovirt host, and then go the Admin GUI and under the Virtual Machines tab clicked on Import. From there I chose Source: VMware Virtual Appliance (OVA), and selected the (local-to-the-host) path where I put the OVA file. After clicking Load it displayed the vm name in the window. I click on that and click the right arrow to and then Next. Then I select my storage domain to use and continue. It loads the VM and starts to process it internally with virt-v2v, but then it inexplicably fails. The only message in the GUI is: Failed to import Vm <vm name> to Data Center Default, Cluster Default I tried to look into /var/log/vdsm/vdsm.log looking for any errors. I found this: Thread-88166::ERROR::2016-11-05 16:36:09,219::v2v::674::root::(_run) Job u'cdb1e eb7-63f3-46e8-abd5-5292dcc8809a' failed Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 669, in _run self._import() File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 696, in _import self._proc.stderr.read(1024))) V2VProcessError: Job u'cdb1eeb7-63f3-46e8-abd5-5292dcc8809a' process failed exit -code: 1, stderr: virt-v2v: error: unable to rebuild initrd (/boot/initramfs-4.2.6-301.fc23.x86_64.img) because mkinitrd or dracut was not found in the guest If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] I don't understand this error because /usr/bin/dracut certainly exists in the VM.

3.6 to 4.0 Functionality Elevation
by Clint Boggio 06 Nov '16

06 Nov '16

Greetings OVirt Community I have a production system that started life as a OV 3.6 system, and I've recently upgraded the engine to 4.0. I see in the cluster config, a configuration element that indicates the cluster functionality level. It has a drop down that allows me to toggle between 3.6, and 4.0. If I select 4.0 and save, what potential problems could I expect ? Setup; 1 Dedicated engine CentOS7 OV version 4 6 hosts running CentOS7 and OV version 4.0 and 3.6 repos. Main data domain is iscsi over IB. ISO and all other data domains are NFS over IB

Migrate oVirtBackup to sdk v4: How to create a snapshot
by gregor 06 Nov '16

06 Nov '16

Hi, I'm started the migration of my backup tool [1] from sdk v3 to v4. Whats the correct REST URI to create a snapshost from a given VM and how can this be done with the SnapshotsService.add(...) method? This method needs a "snapshot" object, but currently I don't know how to obtain one from a given VM or initialize one which works with the SnapshotsService class. A REST way will also be interesting because the Python SDK is horrible documented and I plan to move to basic REST. Also the Python SDK has lots of bug's which consumes many of the migration time. For example a obtained VmService object get by the VmsService.list(with filter) method has no information about the ID but iterating over all objects from list() without filter result in usable VmService objects. This will later be documented, meanwhile I wrote a workaround. cheers gregor [1] https://github.com/wefixit-AT/oVirtBackup
