Hello OpenNebula users,<br><br><br>I defined one VM template with the following attributes:<br>CPU=0.5<br>VCPU=1<br><br>As I read in the OpenNebula Documentation, this should give my VM half a processor. The problem is that I don't think the CPU parameter is ever used.<br>
I took a look at deployment.0 and at source code and I found out that only the parameter VCPU is used when KVM is chosen as hypervisor.<br><br>In fact, I ran on my VM the command 'stress -c 50', so it would force the VM to use all the available CPU. The VM used all the processor, and not only half.<br>
<br><br>I was wondering what you guys use to define a hard limit. Can cgroups solve my problem and be easily integrated with OpenNebula?<br><br><br>Cordially,<br><br>Antonio Carlos Furtado<br>
