Currently we have an OCaml library for generating the qemu command line (used only by ‘virt-v2v -o qemu’). However we also generate a qemu command line in ‘lib/launch-direct.c’, and we might in future need to generate a ‘-readconfig’-compatible configuration file if we want to go beyond 10,000 drives for scalability testing. Therefore this patch series reimplements the qemu command line code as

Hi, I have a function that I'm writing. The arguments in the function are as follows RFF<-function(qtype, qOpt,...){} i.e., I have two args that are compulsary and the rest are optional. Now when my user passes the function call, I need to see what optional args are defined and process accordingly...what I have so far is..

Hi again, I was just looking around for ESFQ sources, and I see that the main site is down, and only has kernel 2.6.4 patches. Is ESFQ maintained? If so, where can I find patches for 2.6.10?

Hi there, I initially asked about this on r-help and was told this might be a better venue. I?m not really convinced from reading the posting guide, but I?ll give it a shot. It was also suggested that the R-Project doesn?t really care about building with ?non-standard? compilers, but I can?t find any evidence of that on the website (indeed, there?s some mention of successful past builds, and the
