[one-users] Beginner questions: Opennebula 2.2.1

[Neumann, Steffen]

Hi,

I think you understood things correctly,
in ONE you create and shutdown instances, 
and you get new VM IDs for every cycle.

So in our HPC setup, we get "fresh" virtual compute nodes 
with every onevm create. 

What exactly do you want ? Do you need the changes to be persistent ?

yours,
Steffen

Hi!


I'm experimenting with opennebula 2.2.1 on Centos 5.5 i686. So far I am
pleased with the results. I got two KVM nodes and am running two VMs.

Since I am a beginner I can't seem to wrap my head around the lifecycle
of VMs. I looked at the documentation and the shown lifecycle... When I
shutdown a VM instance it is not shown in "onevm list" anymore. I read
that this is normal. If I then want to start it again I have to run
"onevm create centos.one" which is ok, but how do I automate this
process so oned can start it on its own or am I missing something? I am
used to the way virt-manager does things as it leaves an entry for a VM
instance even if its shutdown and keeps the VM ID number... Any thoughts
on this?

One other thing is when I have a VM running on a node and I run
"poweroff" in the VM instance, the VM shuts down and the nodes "virsh
list" shows the VM as not running anymore. On the "oned" server "onevm
list" still shows the VM instance as running. Shouldn't it recognize the
new state of the VM and report something?


 Thanks!
