Pkg xen devel - Mar 2006 - Test version of the glibc with xen flavour

Hi all,

I have built a test version of the glibc with a xen flavour. It is 
available on http://people.debian.org/~aurel32/xen/ . The only 
difference with the version currently in sid is the presence of the 
libc6-xen package.

If you are using xen, please test it and tell me if it fixes speed 
problems. If everything is ok, I will commit it into our SVN.

Bye,
Aurelien

This is only useful/necessary on i386, correct?  I ask becuase you have 
amd64 packages, but I was under the impression that the /ib/tls 
problem/issue/whatever was i386-specific.

Hi Aurelien,

thanks for your work! I will your packages this evening/night and will report 
you if I had success. I will test libc6-xen in dom0 (host system) as well as 
in a domU (guest system). For both type of xen vm's the libc6-xen package 
will be very usefull.

And btw... it's not only because of speed issues without using this special 
libc6-xen package, it also because of having a solution for users that is 
really user-friendly. Until now almost every xen user moved /lib/tls away to 
disable ntpl. But on upgrading libc6 the /lib/tls directory is existing 
again.

Because sometimes a domU (guest) system is not under control of the same 
person maintaining the dom0 (host) system this was really a problem. Not all 
users / customers / linux beginners are clever enough to move /lib/tls away 
after upgrading libc6/glibc, even if xen warns about that problem at least at 
boot time.

If libc6-xen is installed, the user doesn't have to take care of this
problem
at all. So this is (atleast for me) as important as the speed benefit.

I have just noticed that Xen implies an i686 processor, so the libraries 
could be optimized for i686. I will do that in the final package, but I 
won't rebuild the test one, I need my CPU for other things...
