Hello, I am using UML as part of Netkit, to do large scale network emulations. I am interested in the skas3 patch to improve performance. When booting a UML guest system, I get the following output: Checking for the skas3 patch in the host: - /proc/mm...not found: No such file or directory - PTRACE_FAULTINFO...not found - PTRACE_LDT...not found UML running in SKAS0 mode
Suggesting that my Ubuntu 9.10 kernel 2.6.31-20-generic-pae doesn't have the skas patch. After much browsing, the most recent version of the skas patch I could find was at http://uml.linode.com/uml/blaisorblade/patches/skas3-2.6/ and is skas-2.6.20-v9-pre9/ 07-Feb-2007 15:11 I have been unable to apply this to my kernel, many of the folders and files are different to the patch (not suprising given its age). Is the performance boost of applying the skas patches still significant with recent kernels? I am doing large scale emulations, with many virtual machines running Quagga processes. If it is worth it, does someone have a link to installing the patches in a recent version of Ubuntu (or a recent vanilla kernel), or at least a link to the patches? The other alternative is to downgrade my kernel to 2.6.20; would this older kernel performance be offset by applying the skas patches?
