Hello,

I'm build amazon micro instance based on Amazon Ec2 AMI and I have kernel version:

- 3.4.43-43.43.amzn1.x86_64
Code:
# $ s cat /proc/cpuinfo
processor      : 0
vendor_id      : GenuineIntel
cpu family      : 6
model          : 26
model name      : Intel(R) Xeon(R) CPU          E5507  @ 2.27GHz
stepping        : 5
microcode      : 0x11
cpu MHz        : 2266.746
cache size      : 4096 KB
physical id    : 0
siblings        : 1
core id        : 0
cpu cores      : 1
apicid          : 0
initial apicid  : 6
fpu            : yes
fpu_exception  : yes
cpuid level    : 11
wp              : yes
flags          : fpu de tsc msr pae cx8 sep cmov pat clflush mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc up rep_good nopl nonstop_tsc pni ssse3 cx16 sse4_1 sse4_2 popcnt hypervisor lahf_lm dtherm
bogomips        : 4533.49
clflush size    : 64
cache_alignment : 64
address sizes  : 40 bits physical, 48 bits virtual
power management:

What I'm trying to figure it out is to how enable NX(No Execute) Protection on that virtual instance. I tried installing pae kernel but it looks like package is not found for this distro.
I think it might be something related specifically to that AMI and maybe someone had an issue like that in the past, so any input is appreciated.
Thanks !!
