SLES 10 Linux Guest Operating Systems Can Cause Poor Networking Performance in Virtual Machines (461197)

Details

My virtual machine with SLES 10 Linux guest demonstrates poor networking performance. Is there a fix to this problem?

Solution

Poor networking performance has been observed in virtual machines with SLES 10 Linux guests, but other versions of Linux guests based on the 2.6 kernel can also cause this behavior.

This problem hasn't occurred in virtual machines with RHEL 4, but it might occur if certain non-default driver functions are enabled.

To work around this problem:

  1. Open the /etc/modprobe.conf file, or create a /etc/modprobe.d/vmware file if /etc/modprobe.conf doesn't exist.

  2. Add the following to the end of the file:

install pcnet32 /sbin/modprobe -q --ignore-install vmxnet; /sbin/modprobe --ignore-install pcnet32 $CMDLINE_OPTS
