[gentoo-hardened] hardened and 64bit

[Marcel Meyer]

Hi,

I want to set up a new hardened system which will host the usual LAMP 
(perhaps only within a VM?) and a vmware-server (since I wasn't able to 
find a OSS (para-)virtualisation solution which would support using 
grsecurity without hassles [*]).

Does anybody here has experiences when it comes to 64bit and a hardened 
gentoo system (no SELinux, just grsecurity and the default stuff ;-) )?

I would like to stay with "stable/amd64" and not "testing/~amd64". So can I 
assume everything works as flawlessly as with "x86"? Or should I be careful 
and stay with 32-bit "x86"? This would be my first amd64 system so asking 
in advance seems to be the less nerve-wracking way *g*

Thanks,
Marcel

[*]
- linux-vserver/openvz don't use several kernels and therefore different 
  configurations for each "VM"
- XEN needs a lot of patching and is difficult to patch together with 
  grsecurity
- KVM isn't ready yet and my CPUs don't support Pacifica either ;-)
- Qemu is not very powerful (performance wise)
