[Users] VM payload
by René Koch (ovido) 01 Jan '14

01 Jan '14

Hi, I created a vdsm hook script for passing payload information (vm name) to a virtual machine, which is placed in before_vm_start folder on my hypervisor (CentOS 6.5). If I create a new virtual machine out of a template some strange things happen: When starting the vm the first time I can see that the vdsm script is executed, but no additional cd drive is shown in this vm. But after shutting down the vm and powering on again, the cd drive appears. Here's the vdsm hook I use: https://raw.github.com/ovido/ovirt-stuff/master/hooks/50_payload I don't really get why the payload isn't working when starting a vm the first time. This happen on oVirt 3.2 and 3.3. Thanks a lot for help! -- Best Regards René Koch Senior Solution Architect ============================================ ovido gmbh - "open source solutions" Brünner Straße 163, A-1210 Vienna Phone: +43 720 / 530 670 Mobile: +43 660 / 512 21 31 E-Mail: r.koch(a)ovido.at ============================================

[Users] VM not starting up
by Nauman Abbas 31 Dec '13

31 Dec '13

Hello all, First of all thank you for your help, I've finally managed to get my Cluster configured properly but now that I create VMs I'm facing another problem. Whenever I start my VM I get this error. "VM TestVm is down. Exit message: Child quit during startup handshake: Input/output error." I've googled around but haven't found any satisfactory solution. If anyone can help out it would be great. Regards Nauman Abbas Assistant System Administrator (LMS), Room No. A-207, SEECS, National University of Sciences & Technology, + 92 321 5359946

[Users] python-sdk : how to modify a vm to "Run on" a "Specific" host and set "Migration Options
by karthik S 30 Dec '13

30 Dec '13

Dear Users, I am karthik, based in Mountain View, CA. I have been using python ovirtsdk for QA Automation tests for RHEV-M for past two months. My knowledge on ovirtsdk is intermittent at this stage. I want to do the below actions that we do on rhev-M using python ovirtsdk. On, RHEV-M UI ============ 1) right click a offline VM >> Edit >> Host >> "Run On:" >> Specific >. choose a hostname 2) right click a offline VM >> Edit >> Host >> "Migration Options:" >> "Do not allow migration" python Code: ========== 1) The VM was imported from export domain to my storage_domain using the code def import_vm(self, source_vm_name, dest_vm_name, storage_domain_name, rhev_host_name=None, cluster_name="Default", async=False): """ Import VM From a Export domain into your storage domain """ timeoutSec=1800 pollInterval=2 exportStorageDomain = self.api.storagedomains.list(type_="export")[0] actionParams = params.Action( storage_domain=self.api.storagedomains.get(storage_domain_name), cluster=self.api.clusters.get("Default"), clone=1, vm = params.VM (name=dest_vm_name, snapshots=params.Snapshots(collapse_snapshots=1), disks = params.Disks(clone = 1), host = params.Host(name=rhev_host_name) )) exportStorageDomain.vms.get(source_vm_name).import_vm(actionParams) start = time.time() while self.api.vms.get(dest_vm_name).status.state != 'down': if time.time() - start > timeoutSec: raise Exception("Timed out (%s) waiting for %s to obtain down status" % (timeoutSec, vm_name)) time.sleep(pollInterval) return self.api.vms.get(name=dest_vm_name)[0] Issue : Upon import, this method did not set the "Run as" to the specified host but "Run as" was set to "Any host in the cluster". Am I missing something ? 2) Secondly, I tried modifying the VM "Run as" hostname with the below code >>> api = API (url = "xx" , username ="XX", pasword ="XX", ca_file = "ca") >>> vm_obj = api.vms.list(name="test_vm_101")[0] >>> vm_obj.set_host="rhev1" >>> vm_obj.update() This did not help either. Seems I am missing something.. 3) finally how to set " "Migration Options" ? Your help would appreciated and will help me to get greater understanding of the SDK itself. Thanks, Karthik

[Users] Attach nfs domain to gluster dc
by Juan Pablo Lorier 30 Dec '13

30 Dec '13

Hi, I've created a new DC in order of been able to create vms on a glusterfs data domain. As ovirt does not allow to share export and iso domains between DCs (nice RFE) I detach those from the actual DC and when I try to attach them to the new DC, I get an error: 2013-12-10 15:19:28,558 ERROR [org.ovirt.engine.core.bll.storage.NFSStorageHelper] (pool-6-thread-46) The connection with details 192.168.128.81:/home/exports/export failed because of error code 477 and error message is: problem while trying to mount target 2013-12-10 15:19:28,577 ERROR [org.ovirt.engine.core.bll.storage.ConnectStorageToVdsCommand] (pool-6-thread-46) Transaction rolled-back for command: org.ovirt.engine.core.bll.storage.ConnectStorageToVdsCommand. 2013-12-10 15:19:28,578 ERROR [org.ovirt.engine.core.bll.storage.NFSStorageHelper] (pool-6-thread-41) The connection with details 192.168.128.81:/home/exports/export failed because of error code 477 and error message is: problem while trying to mount target 2013-12-10 15:19:28,587 ERROR [org.ovirt.engine.core.bll.storage.ConnectStorageToVdsCommand] (pool-6-thread-41) Transaction rolled-back for command: org.ovirt.engine.core.bll.storage.ConnectStorageToVdsCommand. But if I mount the nfs share manually from the hosts, I have no problems. I've been having issues with nfs since I updated to 3.3.1, I have the nfs shares in one of the hosts of the iscsi domain and the other host complaints about not been ablo to access the domains from time to time. The host where the shares are never complaints. Any hints? Regards,

[Users] ovirt-engine 3.3.2 on F20
by Earl Potter 30 Dec '13

30 Dec '13

I'm having a bit of a struggle getting ovirt-engine to install on an F20 box. I first install ovirt-release-fedora.noarch which sets up /etc/yum.repos.d/ovirt.repo and points to $releasever. However, there doesn't seem to be any F20 ovirt repos. Yum is trying to look here: http://resources.ovirt.org/releases/3.3.2/rpm/Fedora/20/ But it seems 3.3.2 is located here: http://resources.ovirt.org/releases/3.3.2/rpm/Fedora/19/ I try changing the repo definition and most everything looks like it's going to install. however, it ends w/ a file conflict between two packages, ovirt-log-collector and sos from F20. Transaction check error: file /usr/lib/python2.7/site-packages/sos/plugins/postgresql.py from install of ovirt-log-collector-3.3.2-2.fc19.noarch conflicts with file from package sos-3.0-3.fc20.noarch file /usr/lib/python2.7/site-packages/sos/plugins/postgresql.pyc from install of ovirt-log-collector-3.3.2-2.fc19.noarch conflicts with file from package sos-3.0-3.fc20.noarch file /usr/lib/python2.7/site-packages/sos/plugins/postgresql.pyo from install of ovirt-log-collector-3.3.2-2.fc19.noarch conflicts with file from package sos-3.0-3.fc20.noarch I'm not really certain how to work around this short of installing an F19 system. Any thoughts would be appreciated. Thank you, Earl
