[ovirt-users] oVirt 4.3 - create windows2012 failed due to ovirt-imageio-proxy

Hi, I tried to create windows2012 vm on nfs data domain, but the disk was locked. Found the error message as following: Connection to ovirt-imageio-proxy service has failed. Make sure the service is installed, configured, and ovirt-engine certificate is registered as a valid CA in the browser. Is this known issue? Thanks, Jingjie
