I need to compile a 2.6.27 xen-kernel to upgrade because I have problems getting nfsv4 to work on my current setup. I am following this guide.

I’m writing this because I had problems when compiling. I got an error on the common_64.o. I didn’t find anything when searching this error. So I was grateful when I found this post, that led me past the error. In this post the option CONFIG_IA32_EMULATION=y is mentioned. And when I activate that option in menuconfig, I can continue compiling.

update 090712: I managed to compile the kernel. I also found a post explaining that my problem booting a standard Ubuntu-kernel in a domU shouldn’t exist. This led me to do another search for reasons why my domU wouldn’t boot. And as I found out, ofcourse, my only problem is that I don’t get any console (as in xvc0.., xm console). I haven’t sorted that out yet. I will update when I do. The updated kernel, a 2.6.27-14-server from ubuntu repos., made my nfs-problems disappear. =) \o/ I will now proceed with getting nfs4 and with auth against Zeroshell krb5 working.

It seems that the days when you needed to keep you computer clean and tidy are gone. With the operatingsystems only require a few percent of your harddrive this might be less of a problem. But my experience is that it still fills up and you may lose focus from the “system-near” files and
only try to clean up your other data (like larger mediafiles or old backups).

I most recently used this tool when my Windows-partition on my work-laptop.

jDiskReport – Cross platform using java (Mac/Windows/Linux)

There are many similar tools for both Windows and Linux. jDiskReport is the best free one I’ve found.
In Ubuntu you can install a gnome tool but I don’t remember the name of the package right now. I will update this when I do. For KDE there is Filelight. But I haven’t tried it yet.

This Google-page has a summary of a bunch.

I found myself in a bit of a dilemma again because I’m still running Ubuntu Hardy Heron (8.04) on my server. In the long run I will probably migrate my Xen-machines to running on KVM in line with Ubuntu 8.10 and 9.04. But for now that’s another project.

I have a Digikam installation on a Ubuntu Hardy that runs quite well. My problem recently arose when I tried to convert RAW images with the built in rawconverter (residing in the kipi-plugins package). I also tried using plainly dcraw wich is the utility that the rawconverter plugin is based on. Both of them returns an image that has a yellow tint. Diggin further I have come to the conclusion that new support for my camera is added in dcraw 8.89 and therefor I’m trying to build my own updated support for this into Digikam so that I can convert theese images until I decide to upgrade to the latest stable Ubuntu, Jaunty (9.04) or later.

I have succeded in compiling kipi-plugins and required packages that didn’t already exist or needed update. The problem now is that it seems like i need to upgrade Digikam too because it crashes using the new kipi-plugins.

My conclusion now is that I am probably better off trying to get that machine upgraded to Ubuntu 9.04 Jaunty.

I’m using Digikam on my laptop to manage my photos. I recently bought a new camera using. And now I’m trying to setup an centralized environment on my server (running xen). Although the thought of editing high-resolution photos through VNC doesn’t seem like a great idea, it seems possible to at least use the tagging and managing features in Digikam. Using X11 forwarding is even slower, especially when displaying the images. The tests I’ve done so far has been over wifi (11G) , so if I would use wired LAN it might work good enough. The original idea on how to transfer the images to the server was simply to connect the camera directly via USB (ptp), passed through to the virtual guest server. But that just doesn’t seem to work. The passthru possibilities in Xen isn’t good enough. I’ve managed to get mass-storage devices to function, using pci-passthru, but my camera can only handle USB-ptp mode. So for now, as a workaround, I’ve setup a samba share on the network for importing pictures (basicly a predefined folder on the virtual server). And I’m thinking about buying a card-reader to the server. If anyone got any tips on this, please let me know.
