[one-users] VM Failed during "Save-As" on a Running VM+CentOS 6.3 x86_64bit + KVM

[Lawrence Chiong]

Hello,

I encountered another issue while doing demo for the features of "Save-As"
image on a Running VM which I suppose to use as my Base-Image for the rest
of my VM to be deployed. During the process after EPILOG status the VM goes
FAILED as per log below. And my Image being save goes "ERROR" from "LOCKED"
after I deleted the Failed VM.

Scenario:

OpenNebula FE - CentOS v6.3 x86_64bit
OpenNebula Node - CentOS v6.3 x86_64bit
iSCSI Target - CentOS v6.3 x86_64bit
iSCSI initiator - CentOS v6.3 x86_64bit

sidenote: I'm wondering on /var/lib/one/remotes/tm/iscsi/mvds as it starts
the error

Thank you.
