Okay,
it seems to be that the Storage IO is the Problem - every Write and Read Pr=
ocess takes a lot of time
Sometimes the copy Job stops with 0/Byte and the traffic goes up and down l=
ike a mountain.
But the Storage Read and Write M/s looking fine... I don't get it
Any toughts?

Hey Guys,
We Deploy a lot of Templates. We got our Training Environment build in Ovir=
t.
Our Problem - when we Deploy the Same Template. The VM=B4s getting slower e=
very Time we deply a new VM from that Template.
And I really don't know why. RAM locking good - CPU and Network looking goo=
d.
But it take about 15 Minute to create a new Template based VM - normaly it =
takes about 30 Seconds.
I checked nload and the Interface traffic - but its not really high.
Can someone explain why its getting so slow and how to troubleshoot?
