Re: [Xen-users] Frist try of Xen-3.2 on Slackware 12

[xdub <xdub@xxxxxxxxxxx>]

Hi Steve,

With version 3.1.3 of Xen, I am able to boot until this error message,
then the server reboot.

But on Slackware there is no "tls" under "/lib" neither under "/usr/lib".

I read on Gentoo doc that we can disable "tls" flag by setting this
CFLAGS="-mno-tls-direct-seg-refs" before compilling the kernel
(http://gentoo-wiki.com/HOWTO_Xen_and_Gentoo)

So, I am going to try, and rebuild a customized kernel.

To make things more difficult, I am on XFS filesystem (mkinitrd resolved 
this issue).
No need to install "swaret" for GNU GRUB support, version 0.97 do its job,
even with XFS filesystem. Just follow the step by step instructions found on
GNU GRUB documentation ... ;-)

I keep you informed with version 3.1.3 before to make another try with 
version 3.2.
Regards
