No, at this point in time nohting is solved. I just moved from
attempting to migrate to just attempting to get a VM up and running on
the new host.
I will have a look at your suggestions tomorrow morning and report back.

Hi
So, then you have solved you restore issue? The permission issue is
usually because a misconfigured qemu.conf (dynamic_ownership [1]) or a
problem accessing the datastore from the hosts (mount points, mismatch
ID of oneadmin...)
Regarding the network problem you have to create bridge1 in the hosts
and bind it to the target physical Host for the dummy configuration.
However if you are using other modes like 802.1Q then the bridge is
created for you. This depends on how the host was defined. Information
about networking modes and configuration is here[2]

some more on this:
I installed kvm, this was obvious, as well as bridge-utils;
apt-get install kvm bridge-utils -y completed.
does not look to copy, copied manually to HOST
chmod -R 755 /var/lib/one/remotes on MASTER and HOST
Ran it manually on the master and :
oneadmin@MASTER:~$ virsh --connect qemu:///system restore
/var/lib/one//datastores/0/164/checkpoint
Domain restored from /var/lib/one//datastores/0/164/checkpoint works
http://dev.opennebula.org/issues/1324; hashed out == if, pointless
I have a later version anyway.
oneadmin@chaos:~$ /var/lib/one/remotes/vmm/kvm/restore
/var/lib/one//datastores/0/166/checkpoint <-- works as well.
Now I am just trying to deploy a VM on the machine, lets just
instantiate one here and I get:

Now i have not bridge configuration on the MASTER and I have
observed from deleting and creating a VM that OpenNebula is doing
all the interface configurations its self, which I do vaguely
remember getting working last time so I am not sure why its not
working here.
Any thoughts?

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

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
