At work I'm building a proof of concept virtualized 4 node cluster on a 6 CPU 256Gb real memory RHEL 6.2 server. Each node is going to be a RHEL 6.2 64bit server on one cpu with 2Gb of memory. That leaves 2 CPU's for the hyper-visor and more then 1/2 the memory. The solution is that once the 4 nodes are up with there product stack, users can clone them in to a new 4 node cluster, mess it up, then delete the clones.
RHEL 6.2 has the following packages for KVM ( aka the hypervisor, etc ) qemu-kvm-tools-0.12.1.2-2.209.el6_2.4.x86_64 qemu-kvm-0.12.1.2-2.209.el6_2.4.x86_64 libvirt-0.9.4-23.el6_2.4.x86_64 virt-manager-0.9.0-7.el6.x86_64 libvirt-client-0.9.4-23.el6_2.4.x86_64 virt-viewer-0.4.1-7.el6.x86_64 As you can see it's older and missing kvm-virtio which I am not sure is going to present a problem. I need to demo this solution ASAP so that 32 CPU server can be ordered so that many 4 and 2 node clusters can be run on the same system. While also being available on reservation for 32 CPU HPC jobs. Questions: - Anyone know of any good resources for KVM/Virtualised server documentation as in howto or walk thoughts? - Any information on how to setup the network in this environment for bridged and insights on kvm-virtio would be appreciated. - RHEL 6.2 has a QXL video driver which matches KVM's virtulized video adapter, anyone know anything about that? or can point me in the right direction. - The network does not need to route outside of the hypevisor node ( users login to the node and ssh to the nodes), so is there a driver or known settings for optimal response. - Any documents on techniques of cloning nodes would also help, since new names and IP would need to be used in the final solution since many 2 or 4 node clusters will need to run side by side. I will be more then willing to present this as a talk using CentOS 6.2 ( since it's the free version of RHEL http://www.centos.org/ ) later in the year. Any assistance is appreciated, and will be recognized in said talk. -- /** ** Joe Apuzzo ** Call Sign: KD2AKU ** PGP/GPG: pub key ID BB5C7 **/
