Hi
Right now I have a OpenNebula server, running the front end (SunStone)
and host all on one machine. It works great. Lets refer to this as the
master.
I am trying to add a new host (reffered to as the host) to run more
VM's. I am attempting to migrate from the master to the host without
success. Firstly, what is installed:
MASTER
uname -a
Linux MASTER 3.2.0-4-amd64 #1 SMP Debian 3.2.35-2 x86_64 GNU/Linux
cat /etc/debian_version
7.0
ii opennebula 3.4.1-3.1 amd64 controller
which executes the OpenNebula cluster services
ii opennebula-common 3.4.1-3.1 all empty
package to create OpenNebula users and directories
ii opennebula-sunstone 3.4.1-3.1 all web
interface to which executes the OpenNebula cluster services
ii opennebula-tools 3.4.1-3.1 all
Command-line tools for OpenNebula Cloud
ii ruby-opennebula 3.4.1-3.1 all Ruby
bindings for OpenNebula Cloud API (OCA)
ii kvm 1:1.1.2+dfsg-5 amd64 dummy
transitional package from kvm to qemu-kvm
ii qemu-kvm 1.1.2+dfsg-5 amd64 Full
virtualization on x86 hardware
ii libvirt-bin 0.9.12-5 amd64 programs
for the libvirt library
ii libvirt0 0.9.12-5 amd64 library for
interfacing with different virtualization systems
ii python-libvirt 0.9.12-5 amd64 libvirt
Python bindings
HOST
uname -a
Linux HOST 3.2.0-4-amd64 #1 SMP Debian 3.2.35-2 x86_64 GNU/Linux
cat /etc/debian_version
7.0
i opennebula-common 3.4.1-3.1 all empty
package to create OpenNebula users and directories
ii opennebula-node 3.4.1-3.1 all empty
package to prepare a machine as OpenNebula Node
ii libvirt-bin 0.9.12-5 amd64 programs
for the libvirt library
ii libvirt0 0.9.12-5 amd64 library for
interfacing with different virtualization systems
Reading /usr/share/doc/opennebula-node/README.Debian it tells you what
to do, I followed those instructions, everything completed successfully.
Things I find odd... kvm/qemu-kvm packages are not installed on the HOST
but that README file says to ensure that the kernel modules are loaded
which they are.
oneadmin@MASTER:~$ onehost list
ID NAME CLUSTER RVM TCPU FCPU ACPU TMEM FMEM
AMEM STAT
2 MASTER.matrix Internal 16 3200 2509 200 126.1G 27.2G
22.1G on
4 HOST.mat - 0 1600 1600 1600 31.5G 31.1G 31.5G on
But that said, here is what happens in the VM's log when I try to migrate:

I can work out this operation is that is not permitted, is it a
permissions issue? What host is this error originating from.. is it
saying the MASTER does not have access to that file or the HOST? I have
no idea.
Any help appreicated.
Thanks
