[ovirt-users] Ovirt Error after creating a VM image

Hi, I wrote an automation that provisioning a VM using ovirtsdk4 (we are using Ovirt 4.3). In the last week, we notice that sometimes the VM provisioning is failing with this error: "The response content type 'text/html; charset=iso-8859-1' isn't the expected XML" This error is happening when the automation is creating the VM image and waiting for its status to get change from "image-locked", this to be able to set affinity on it and later to start the new VM. So the error is happening while the image is in "image-locked" state. Can you please let me know why it is happening (note that it is occurring like 1 out of 4 attempts) and how can it get fixed? Thanks, Lavi
