2.4.3 TLS Libraries

Users of the XenLinux 2.6 kernel should disable Thread Local Storage (e.g. by doing

a mv /lib/tls /lib/tls.disabled) before attempting to run with a XenLinux

kernel

. You can always reenable it by restoring the directory to its original location

(i.e. mv /lib/tls.disabled /lib/tls).

The reason for this is that the current TLS implementation uses segmentation in a way

that is not permissible under Xen. If TLS is not disabled, an emulation mode is used

within Xen which reduces performance substantially.

We hope that this issue can be resolved by working with Linux distribution vendors to

implement a minor backward-compatible change to the TLS library.

2.5 Booting Xen

It should now be possible to restart the system and use Xen. Reboot as usual but choose

the new Xen option when the Grub screen appears.

What follows should look much like a conventional Linux boot. The ﬁrst portion of

the output comes from Xen itself, supplying low level information about itself and the

machine it is running on. The following portion of the output comes from XenLinux.

You may see some errors during the XenLinux boot. These are not necessarily any-

thing to worry about — they may result from kernel conﬁguration differences between

your XenLinux kernel and the one you usually use.

When the boot completes, you should be able to log into your system as usual. If you

are unable to log in to your system running Xen, you should still be able to reboot with

your normal Linux kernel.

If you boot without ﬁrst disabling TLS, you will get a warning message during the boot process. In

this case, simply perform the rename after the machine is up and then run /sbin/ldconfig to make

it take effect.
