Are you using pygrub to boot, or do you boot from a kernel/ramdisk that
live outside the domU filesystem?

I am using the host kernel, and i made a ramdisk w/o scsi modules to prevent kernel panic. Do u prefer pygrub?

Truthfully, most of our domU instances don't have any swap configured.
Even if we have it, it's only a safety net to buy some time before the
OOM killer destroys a runaway process, so top performance from swap
isn't really a consideration.  RAM is cheap and plentiful nowadays.
Alternatively, you can always create a swap file if you prefer not to
create a dedicated swap volume.

So you just assign enough RAM and forget about the swap....
As already alluded to on this thread, a 64-bit kernel is superior to a
32-bit kernel.  With a bit of care, you can even boot and run a 32-bit
distro from a 64-bit kernel, so there's little reason to suffer with the
tls workaround unless you have ancient hardware that isn't 64-bit

Thnx to fajr the cure was in his reply. i think i might consider 64bit...
