Firstly, it occurred to me that Centos 6 might not provide the virtualization rpms like it did with Centos 5. RH makes this an add-on to their license. Does anyone know if the upcoming Centos 6 will provide the virtualization packages (right away or in the future)?
I installed SL 6.0 on one of my machines, and indeed it provides KVM (Description in French): # yum groupinfo virtualization Loaded plugins: refresh-packagekit Setting up Group Process epel/group_gz | 201 kB 00:00
Group: Virtualisation Description: Fournit un environnement afin d'héberger des clients virtuels. Mandatory Packages: qemu-kvm Optional Packages: qemu-kvm-tools
I think CentOS will do the same for 6.0.
Secondly, I'm not sure I understand the CPU allocation stuff. If I have 6 cores, it appears I can only create VMs that use 6 cores total. Using the GUI for creating a new VM will provide me with a max number I can allocate. Does this mean that I can allocate, for example, 3 VMs that use 2 cores each and never be able to create any other new VMs or does this mean I can create as many VMs as I want but only start VMs that use the max total cores or less?
You can assign multiple VMs to one CPU. For example, you can have a hostmachine with dual-CPUs quadcore, and have 15 VMs or more installed on it, and some of them assigned with two cores or more. It is only more threads on a core.
