Hi, Today after I reinstalled my hypvervisors I just got 15MB of RAM inside my guests. I hade this problem on one of my hypervisors before but if I started the VMs on the other hypervisors and then migrate the VM to the "faulty" hypervisor all was ok. Just because of that behavior I then started to reinstall my hypervisors today. I am using Centos 6.3 with Dreyous 3.1 repo. After the install i enabled and installed the Intel(Fake) CPU-package on all of the hypervisors. Now when Im trying to start a VM I only got 15MB of RAM inside the WM, almost impossible to boot of course. One of the machines is definied to use 2048MB and has 2048MB as "guaranteed memory". I have attached the vdsm.log from the hypervisor that the VM try to start on. Regards //Ricky
