Is there a performance reason why you have 8 vCPUs assigned to the VM? Unless you are planning an absolutely massive load-balance pool that can actually use this arrangement you should drop this considerably according to VMWare best practice.
My understanding is that, every time you introduce another vCPU, the overhead for context-switches, register flushes, synchronisation and the like increases considerably, especially when you are spreading the vCPUs across different dies. Unless you have applications that absolutely have to have access to the CPU power, you really want to cut the cores to the bare minimum. Try starting with 1vCPU and 4GB RAM and work your way up until you start to hit performance limits. Also, when you are seeing 100% CPU usage, what does the output of the "Top" command show?

I have one testing v2RC1 installation on a vmware virtual machine. I have no more traffic (only tests) and I don't know why, 2 times, system hangs ..... the reason is cpu becomes 100% usage and system becomes unusable.... can anyone help me pleas? I don't think will be a hardware problem, because i have other machines running perfectly, and for this Zen machine I reserved 4Gb RAM and 8 CPU Xeon E5620 I installed ther kernel 2.6.32-5-686-bigmem to allow more than 4Gb RAM (in future I'll assign 16Gb ). May be have to install linux-image-2.6.32-5-vserver-686-bigmem kernel???
