Getting error while trying to add VmPool using ovirtsdk4 version of the python api
by Manuel Luis Aznar 10 Feb '17

10 Feb '17

Hello there, I am trying to add a VmPool to oVirt using the python ovirtSDK4 with following lines: I am omitting the import packages lines and connection lines. system_service = connection.system_service() vm_pools_service = system_service.vm_pools_service() templates_service = system_service.templates_service() clusters_service = system_service.clusters_service() tplist = templates_service.list(search='name=prueba') tpl=None biggest=-1 for t in tplist: ver = t.version if ver.version_number > biggest: biggest = ver.version_number tid = t.id tpl = t c = None for cluster in clusters_service.list(): if cluster.name == 'Pruebacluster': c = cluster pool = ovirtsdk4.types.VmPool(name='PRUEBA',size=1,type =ovirtsdk4.types.VmPoolType('manual'),template=tpl,cluster=c) vm_pools_service.add(pool=pool) I am getting the following error: Fault reason is "Request syntactically incorrect.". Fault detail is "For correct usage, see: https://ovirt.example.com/ovirt-engine/api/v4/model#services/vm-pools/metho…". HTTP response code is 400. I am a newbie in using this version of the API, suppose this is quite easy problem. Thanks for all the answers to come, Manuel

Team, After a host update on my cluster, All of my Windows vm's running the vdagent from the ovirt tools are running at 100% CPU utilization. Any ideas why would this happen? Regards, -- Fernando Fuentes ffuentes(a)txweather.org http://www.txweather.org

Importing existing (dirty) storage domains
by Doug Ingham 09 Feb '17

09 Feb '17

Hi All, My original HE died & was proving too much of a hassle to restore, so I've setup a new HE on a new host & now want to import my previous data storage domain with my VMs. The problem is when I try to attach the new domain to the datacenter, it hangs for a minute and then comes back with, "Failed to attach Storage Domain data2 to Data Center Default" It's a gluster volume, and I'm able to mount & write to it via the CLI on the host, without issue. It's also using the same gluster volume options as the initialized master domain. I get this in sanlock.log: 2017-02-09 14:54:57-0300 1698758 [9303]: s10:r12 resource 60455567-ad30-42e3-a9df-62fe86c7fd25:SDM:/rhev/data-center/mnt/glusterSD/localhost:data2/60455567-ad30-42e3-a9df-62fe86c7fd25/dom_md/leases:1048576 for 3,15,12533 2017-02-09 14:54:57-0300 1698758 [9303]: open error -5 /rhev/data-center/mnt/glusterSD/localhost:data2/60455567-ad30-42e3-a9df-62fe86c7fd25/dom_md/leases 2017-02-09 14:54:57-0300 1698758 [9303]: r12 acquire_token open error -5 2017-02-09 14:54:57-0300 1698758 [9303]: r12 cmd_acquire 3,15,12533 acquire_token -5 Any ideas? -- Doug

Host DNS
by Todd Punderson 09 Feb '17

09 Feb '17

I changed my DNS servers since installing my hosted engine and hosts. I've manually set my /etc/resolv.conf to have the correct nameserver entries. But I found when I rebooted that it was being overwritten. I did some googling and found that in /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt (My management network name) there is a nameservers config that gets applied when vdsm starts which updated my ifcfg files. I edited that file to include my correct name servers. Now, if I choose a host, go to the network interfaces tab, then click "Setup Host Network" when I exit out with the "Save" checkbox checked, the file in the vdsm directory is being changed back to my old nameserver entry. I searched all over the hosted engine UI and I can't find where that's old entry is coming from. Where do I go to change this? Thanks

Info on oVirt 4.1 and qcow2 v3 format
by Gianluca Cecchi 09 Feb '17

09 Feb '17

Hello, after upgrading to oVirt 4.1 and setting cluster/datacenter to version 4, new images and snapshots should be created in qcow2 v3 format, based on bugzilla included in release notes: https://bugzilla.redhat.com/827529 Correct? What about existing disks? Is there any way to convert? What in case I have an old disk, I create a snapshot in 4.1 and then delete the snapshot? Will the live merged disk be in v3 format or v2? Thanks, Gianluca

Re: [ovirt-users] USB 2.0 compatibility -- RESOLVED!
by Jonathan Woytek 09 Feb '17

09 Feb '17

I was finally able to resolve this. So that maybe other users can find how to fix this if they run into the same issues: tl;dr: Edit the virtual machine in question, go under Console, make sure SPICE is chosen for graphics, and under "USB Redirection" choose "Native." When you reboot the VM, it will have both UHCI and EHCI (2.0) controllers. Now, any USB 2.0 devices that you attach will work correctly. Long version: I struggled with this for quite a while. While doing some additional research, I found a note in the 4.1.0 release notes referencing BZ 1373223. This particular note was for ppc64 architecture systems, but it curiously said that enabling USB Redirection under SPICE would change the USB controllers available on the host. I dug a little deeper into the bug thread and found a couple of references that seemed to indicate that x86/x86_64 exhibited the same behavior. Apparently, UHCI (1.1) is the default because it supports SmartCards, but the EHCI (2.0) controller does not. So, turning on USB Redirection under SPICE settings for the console enables an EHCI controller, thereby enabling devices that require USB 2.0. Personal opinion: This is really obfuscated. It would be great if this switch lived somewhere more obvious. Even if that doesn't happen, this should exist in a document somewhere. Maybe it does and I couldn't find it, but I tried! jonathan -- Jonathan Woytek http://www.dryrose.com KB3HOZ PGP: 462C 5F50 144D 6B09 3B65 FCE8 C1DC DEC4 E8B6 AABC
