Hi list, I need to move 600+ vms:from one data domain to another, however from what i can see in the GUI i can only move one vm disk at the time which would be very time consuming. I there any way i can bulk move those vm disks? By the way, I can't stop the vms they have to be online during the migration.. Regards Christian

If you're planning to do it that way, make sure you install version 3.x of ovirt-engine-sdk-python. Newer versions (4.x) differ too much in syntax. Also, if you want to move a whole Storage Domain, you might be interested in listing VMs by the storage domain name, i.e.: api.vms.list(query='Storage=myoldstoragedomain') That will return a list of all machines in that storage domain.
for vm in vms: print vm.name for disk in vm.disks.list( ): print " disk: " + disk.name + " " + disk.get_alias() sd = api.storagedomains.get('NEWSTORAGE')
try: disk.move(params.Action(storage_domain=sd))
disk_id = disk.get_id() while True: print("Waiting for movement to complete ...") time.sleep(10) disk = vm.disks.get(id=disk_id) if disk.get_status().get_state() == "ok": break
except: print "Cannot move."
api.disconnect()

This is my python program:
# ... API init
vms= api.vms.list(query = 'vmname')
for vm in vms: print vm.name for disk in vm.disks.list( ):
I personally would not move it disk by disk, VM by VM. It'll take a lot of time and you can usually move multiple disks at a time. How many, depend on your storage bottlenecks usually, but few at a time makes sense to me.
print " disk: " + disk.name + " " + disk.get_alias() sd = api.storagedomains.get('NEWSTORAGE')
try: disk.move(params.Action(storage_domain=sd))
disk_id = disk.get_id() while True:
Not breaking for any kind of timeout or state other than 'ok' ?
print("Waiting for movement to complete ...") time.sleep(10) disk = vm.disks.get(id=disk_id) if disk.get_status().get_state() == "ok": break
except: print "Cannot move."
A bit more information here might help diagnosing what has failed. Y.
