Hi, Hoping I am using the right mailing list for this request for help. I created a glusterfs, and sucessfully copied a kvm disk image to it, but when I tried to start the guest, I received these error messages. I'd appreciate any insights into what happens, and suggestions to fixes or workarounds. The same image started fine when it resides in a local fs. Thanks in advance.
