[Users] Problems using the PythonSDK

[Karli Sjöberg]

Hi!

We´re in the process of building an orderportal where our customers will be able to log in, select a virtual machine template, type in a desired hostname and it will be automatically created, and they recieve a mail explaining what they´ve gotten themselves into:). For this I figured the PythonSDK would be the best choice but I´m having trouble using it. What we´ve done so far is:

1) Create a new VM from a template; OK. I found an example and it worked OOTB
2) Rename the new VM´s disk from ${TemplateName}_Disk1 to ${VMName}_Disk1; Not OK. I found an example of how to change the name of a VMNic and that works, but using the same method to change VMDisk´s name does not (FYI, the VM only has one VNic and VDisk):
>>> from ovirtsdk.xml import params
>>> from ovirtsdk.api import API
>>> api = API(url='https://${ENGINE}:443/api',<https://storm.slu.se:443/api',> ca_file='${CACERT}', username='admin at internal<mailto:'admin at internal>', password='letmein!')
>>> vm = api.vms.get(name='VMName')

>>> vmnic = vm.nics.get(name='*')
>>> vmnic.name
'nic1'
>>> api.vms.get(name='VMName').nics.get(name='*')
'nic1'
>>> vmnic.name='nic2'
>>> vmnic.update()
>>> api.vms.get(name='VMName').nics.get(name='*')
'nic2'
>>> vmnic.name
'nic2'

>>> vmdisk = vm.disks.get(name='*')
>>> vmdisk.name
'TemplateName_Disk1'
>>> api.vms.get(name='VMName').disks.get(name='*')
'TemplateName_Disk1'
>>> vmdisk.name='VMName_Disk1'
>>> vmdisk.update()
>>> vmdisk.name
'VMName_Disk1'
>>> api.vms.get(name='VMName').disks.get(name='*')
'TemplateName_Disk1'

See? Am I holding it wrong?

3) Create a snapshot called "Origin", so if a customer calls in and says they´ve borked it completely, we´ll just revert to it´s "Origin" and they´re up and running again; OK, found another OOTB example, thank you.
4) Add the customer to VM´s Permissions with an appropriate role; Not OK. I have found no examples on how to do this and just don´t know where to start looking. BTW, creating a new VM with Python results in Permissions completely empty, no inheritance either. Don´t know if that is intended...
