Re: [Xen-users] xen unstable and TLS

[Daniel Mealha Cabrita <dancab@xxxxxxxxxxxx>]

I'm replying to the list (I guess it's what you wanted, since you've wrote 
that in English).


As I wrote before, what I know is from xen-unstable from a month ago, keep 
that in mind.

It's just a guess, but you might have TLS support somehow broken in your OS 
(either that or xen-tools is currently broken, dunno).

The problem on disabling TLS by brute force (the tls-disabled thing) is that 
xen-tools needs that, so you need to compile xen-tools without TLS.
Since there's no "./configure --dont-use-tls" in xen-tools, in order to do 
that you have to modify the code and make it work without using TLS.

I've got a patch here if you want, but it's against the aforementioned 
xen-unstable snapshot.


About the warnings, you're talking about the ones which basically say 'xen 
will work but things will be slower'?
If is that so, you'll need to switch glibc to one with a 'xen-friendly' TLS 
patch (and stuff in initrd and other static binaries will need recompilation, 
obviously).
