Hello,
I am testing some from scratch deployment so I created a stateless vm
and wrote small python script to shutdown and start the vm again (to
revert vm state to starting point).
http://pastebin.com/b5yTFEkN
problem is that after stopping the vm there is a running operation of
snapshot removal and when script try to start the vm it fails with
Failed to Start VM:
status: 409
reason: Conflict
detail: Cannot run VM. Related operation is currently in progress.
Please try again later.
Is there a cleaner way than checking status and looping or waiting some
time to end of this operation? (desclaimer: I am new to python so please
don't hit me :-)
Unfortunatelly, no. You always have to poll the API to check the status
of the operation.
ok, I will
Just for info, we have new Python SDK version 4[1]. Python SDK version
3 will be removed someday in future. So you would have to migrate your
scripts, so maybe better to write it in version 4 now, then rewrite it
later.
thanks for link. Unfortunatelly it looks like there is only 3.6.3.0
version of ovirt-engine-sdk-python in Fedora24 repo at this time (and
ovirt-engine-sdk-python-3.6.9.1-1.fc23.noarch.rpm in /ovirt-4.0 repo for
fc23)
It has different name - python-ovirt-engine-sdk4.
http://resources.ovirt.org/pub/ovirt-4.0/rpm/fc23/x86_64/python-ovirt-engine-sdk4-4.0.1-1.fc23.x86_64.rpm
And also, if you don't know Python, but you know Ansible, you can use
Ansible VMs module[2].
thanks once more. I am using ansible and I will try ovirt module for
sure (but python is on my todo list as well ;-)
Cheers, Jiri
