[one-users] Cannot clone persistent image

Sun Apr 28 21:55:17 PDT 2013

After I restart the Front-end also cannot deploy the VM.

The output of grep -vE '^($|#)' /etc/libvirt/qemu.conf

vnc_listen = "0.0.0.0"

user = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0

The VM log of the failed deployment after restarted with the changes;

By the way, let me clarify again the problem so that the initial problem
will not mislead

The actual problem is not that I could not deploy any VM, but I cannot
deploy any persistent image that I changed into non-persistent image which
I cannot clone also.
