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

This is my python program:
# ... API init
vms= api.vms.list(query = 'vmname')
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()

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.
