[Users] python-sdk : how to modify a vm to "Run on" a "Specific" host and set "Migration Options
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
Hi, take a look at vm.start.__doc__ it should have all the answers you're looking for, as about migrate options, these two [1] are responsible for pinning vm to specific host, possible options for the 'affinity' can be seen at <vm_affinities> [2].

Hi Michael Pasternak, Thanks for the info. I was able to modify the VM as : vm_placement_params = params.VmPlacementPolicy(host = params.VM(name=rhev_host_name), affinity = "pinned") vm_obj.set_placement_policy(vm_placement_params) vm_obj.update() Thanks much !! thanks, Karthik On Sat, Dec 28, 2013 at 11:51 PM, Michael Pasternak <mpastern@redhat.com>wrote:
