There are seven different vzkernel RPMs which are shipped with every Virtuozzo release.

• vzkernel-2.4.20-version.i686.rpm
  
• vzkernel-smp-2.4.20-version.i686.rpm
• vzkernel-enterprise-2.4.20-version.i686.rpm
  
• vzkernel-smpnosplit-2.4.20-version.i686.rpm
• vzkernel-entnosplit-2.4.20-version.i686.rpm
• vzkernel-2.4.20-version.athlon.rpm
• vzkernel-smp-version.athlon.rpm

athlon
kernels are built for AMD Athlon processors, i686 kernels are for Intel
processors. Note that i686 kernels should be compatible with AMD Athlon
processors too.



smp
kernels are for servers with simmetric multiprocessor architecture
(e.g. servers with two processors), as well as for systems with
hyperthreading enabled. There kernels support up to 4 GB of RAM.



enterprise kernels are SMP kernels which support up to 64 GB of RAM.



nosplit
kernels are kernels with 4GB split feature disabled, which provide
better performance on heavily loaded systems that have not many
processes running.



Please don’t forget to install the corresponding version of vzmodules RPM.



Since kernel version 2.4.20-021stab028.18 (released in September, 2005), all kernels include NFS client support.
