Be careful with glibc versions with VMWare on CentOS.  They haven't 
bothered to update for 5.4, and it's very crashy.  You can get the 
libc.so from 5.3 and put it in its library path to help.  Search on 
'vmware glibc 5.4'.

If you're willing to switch from Xen, you might also try out KVM.  It's 
much easier to deal with than the VMWare tomcat/browser/browser-plugin 
monstrosity, especially if you use X.  I've got a Win2K3 machine here in 
an old version of KVM (less optimized) and launching Firefox only 
briefly moved the CPU meter to 23%.  IOW, it seems normal.
