to OpenNebula's ecosystem and/or publishing an entry in opennebula's blog?

Hi Chris
We have a solution we are using on Oracle Exalogic hardware (we are using
the bare metal boxes and gateway switches). I think I understand the
requirement, IB accessible storage from VMs is possible
is:

Is there something else I should do?
Image is not marked as persistent, should it be changed?

You can only use the top 2 most significant bytes, the other 4 are reserved
for the ip to mac conversion open nebula does, the most significant byte is
set to 02: because the second bit should be set to 1 for locally
administered mac addresses 00[1]0 :
I suggest you use mac prefixes
I have done a lot of migrations with VMs on Ubuntu, first give some
information about your source and destination, your storage back end,
architecture type, the source and destination host versions etc. Are you
running the same version of kvm,xen,libvirt on both sides? Post as much as
you can
should be enough for virtualizing
machines.

If you use a qcow backing store this is what happens in the background
qemu-img create -backing_store (your original image) -f qcow2 (running

when you save as its

I tried to add some Ubuntu 12.04 hosts into my cluster and had some
problems deploying VMs on these new hosts.. turns out there was a change
from 11.10..
Changes to Ubuntu KVM packages...
So for some reason Ubuntu 12.04 packages creates two kvm binary links

Wasn't this addressed in the ON 3.4? You should look into the qcow2 driver
in 3.4. If you think its fast now wait till you try the qcow2 backing store
driver.. :)

Hi
The new qcow2 data store configuration is amazing, I just have to
congratulate you guys on using the backing store feature of qcow2. It cuts
VM deployment times by a magnitude. This is a MUST HAVE feature and I would
love to hear some feedback on this change because I'm floored, my 8 min VM
