Hi.<br>
<br>
The shutdown make a copy of a Running machine (after make a
shutdown) is... like a ordered shutdown<br>
<br>
onevm delete, just destroy a VM (not make a copy, therefore is
necesary make de scp manual to keep the lasted VM)<br>
<br>
For example.<br>
<br>
imagine that:<br>
<br>
you, in 2011, make a image and upload to openebula repository
(oneimage create ...). That image is a empty OS<br>
<br>
after, you instanciate that image, and install some app (like
tomcat, for example)<br>
<br>
your machine is running during 2011, and in 2012 (365 days later)
you do the following command:<br>
<br>
onevm delete VM-ID<br>
<br>
Now, you LOST your work during 365 days. Because OpenNebula assumes,
that not need make a copy<br>
<br>
If, instead delete, you use "onevm shutdown VM-ID". OpenNebula
update your repository image. Now you have at local repository an
image updated 365 days.<br>
<br>
Hope that help :)<br>
<br>

The problem is at kvm dom0 (not opennebula) i have a
similar problem some times... but i dont know how
solve... <br>
<br>
in my case. when that happend i just return manually the
image to the repository.<br>
<br>
for example, if the image disk is 111, the VM is 4444 and
the dom0 is 99.99.99.99 i do the following<br>
<br>
as oneadmin<br>
<br>
oneimage show 111 | grep SOURCE<br>
<br>
that return the path, similar like that:
/srv/cloud/one/var/images/5963e9e0f2ed9524e90c3b4c1d8b01ab<br>
<br>
then make a backup (backup are your friend)<br>
<br>
cp
/srv/cloud/one/var/images/5963e9e0f2ed9524e90c3b4c1d8b01ab
/srv/cloud/one/var/images/5963e9e0f2ed9524e90c3b4c1d8b01ab.bk<br>
<br>
now, i can shutdown the VM<br>
<br>
ssh VM && shutdown -h now <br>
<br>
check if at dom0 the VM is running (KVM)<br>
<br>
virsh list | grep one-4444<br>
<br>
(if no output, jump to scp command)<br>
<br>
else do: virsh destroy one-4444 (or destroy VMID)<br>
<br>
and after retreive the image:<br>
<br>
scp 99.99.99.99:/path/to/image/4444/images/disk.0
/srv/cloud/one/var/images/5963e9e0f2ed9524e90c3b4c1d8b01ab<br>
<br>
usually disk.0 is the image correct to backup, but see
deployment.0 file to see if you need backup other disk
(deployment.0 file is at disk.0 directory)<br>
<br>
at the last, delete VM under OpenNebula (onevm delete
4444)<br>
<br>
<br>
Sure you yet know the steps, sorry 4 the possible spam :)
<br>
<br>
keep in touch to see if anybody can resolve the problem to
stop an unstoppable VM.
