OLS Day 2
Were does kernel documentation hide ?
It hides in all kind of different places, in /usr/src/linux/Documentation which isn't on the web
, in papers, in blogs, in Google Video, even in flashfiles .. so Google won't find them, or at least not all of it .
Rob Landley had a 6 month fellowship with the Linux Foundation focusing on cleaning up the documentation ...
The results is http://www.kernel.org/doc/, now if we could only turn it into a Wiki ..
After Robs talk I went into Measuring database performance with NFSv4 .. sadly this Netapp focussed talk covers a proprietary database that I don't care about. The speaker claims that his proprietary vendor prefers NFS to store it's data .. if that's the case I wonder why they are focussing on their own Clusterfilesystem (OCFS2)
Maybe he should have focussed on an open database .. Obviously Netapp is in the business of selling their storage and not Cluster filesystems but I find it hard to believe.... also the fact that they only talk about client optimalization because the server side its a proprietary device wasn't really helping their case.
Obviously I went to the Virtualization of Linux Servers: a comparative study talk which had a standing room, but I'll save my thoughts on that one for a separate post.
Just one thought here .. there is a new benchmark in town namely the number of kernels can you build per hour :)
Next talk was the the Corosync Cluster Engine. Corosync.org isn't up yet but and the source code is about to be released but it aims at becoming the common cluster infrastructure that can be used by different cluster toolsm It will be used as a backend for Pacemaker and is already used by RedHat folks ..
Werner gave an interesting talk on the building of the openMoko NEO during which "nobody" said FSO is Android done right .. FSO being FreeSmartphone.org Werner described the traditional problems a young engineering company has to go trough in order to go from prototype to actual mass production.
So over the past couple of days I ran into people that have much more time to travel and go to events than I do , so who have been to both the Xen summit and the KVM Forum interesting to know that the KVM summit had about 50-60 people and the Xen summit about 100 people now these are developer summits .. not end user conferences like with other technologies.
After dinner there was a BOF about Direct Function assignment benefits by folks from Neterion
The advantage is that it Eliminates overhead of network virtualization
Allows support for a large number of guest with a compact number of ports.
Allows using native OS drivers as is ..
The idea of using bonding of a physically PCI bridged device with a virtual NIC sounds really tempting to enable migration of Virtual machines with a hardware dependency , however I still have some thoughts on that.
