CRAN: How to list a non-Sweave doc under "Vignettes:" on package page?
Hi, is it possible to have non-Sweave vignettes(*) in inst/doc/ be listed under 'Downloads' on CRAN package pages? For instance, in my R.rsp package I have a inst/doc/report.pdf (part of the source *.tar.gz) that is not detected/listed. The PDF is not based on a Sweave vignette but an *.tex.rsp vignette that is dynamically created via inst/doc/Makefile. It is listed (*) BTW, can the

vignettes: .png graphics or pre-compiled .pdf
In a package I'm working on there is a vignette with a number of graphs that result in huge .pdf files, so the .pdf for the vignette is around 17 Mb. If these graphs are converted to .png, and the .tex file is compiled with pdflatex, the resulting .pdf is ~1 Mb. I'm reluctant to put the .Rnw file into the package as is, generating the huge .pdf for the vignette. I first tried

Strange behavior of QoS
Hi, I'm having some weird problem with the setup of the QoS on a bridged network. As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected). Using 1280 units I get a speed og 5Mbps. I'm aware of peak and

Incremental Backups
Hello. Is someone performing incremental backups via libvirt for qemu/kvm machines? I'm still having a hard time to find a nice procedure. I mean is it possible to make a full backup of an image on monday a do the next days of the week incremental backups? Another way could be mount the image and rsync its contents. Does that makes sense? Also i read in qemu changelog: --- Support for a

adjusting the map of France to 1830
I'm doing some analyses of historical data from France in 1830 on 'moral statistics' that I'd like to show on a map. I've done most of my analyses in SAS, but a few things would work better in R. To do this, I have to adjust the modern map, library(maps) map('france') to adjust for changes in departments (86 in 1830, to 97 now). I've read the documentation

Disk-only internal snapshot
Hi all, it's possible to do an internal snapshot with the --disk-only option (for qcow2 images)? The following command virsh snapshot-create-as my-dom my-snap my-description creates an internal snapshot but the following virsh snapshot-create-as my-dom my-snap my-description --disk-only creates an external snapshot. Thanks, Davide. -------------- next part -------------- An HTML

Block device IO limits
Hi all, is there a way to limit the throughput (or the number of operations per seconds) of a block device? I ask because I've a couple of misconfigured VMs that are performing a lot of disk activity (swapping I'd bet but I haven't access to their OS). Since their storage is on a NFS share they are slowing down other VMs on the same share. Thank you. Davide.

Changing QoS on-the-fly
Hi all, it's possible to change/add the QoS settings for a running domain? I edited the domain definition with virsh but it seems to have no effect until I shut down the domain. libvirt version 0.9.13 kvm-qemu version 1.2.0 Best, Davide. -------------- next part -------------- A non-text attachment was scrubbed...
