This flags are strage, PAE (Phisical Address Extension ) refers to 32 bits CPU with memory extension .... 

Execute this : 

lshw -c cpu 

If you do not have it instaled : 

apt-get install lshw 

it will show the name of the processor ...

Hi 

I have a problem with a an AMD pc , I can install proxmox so I know it is 64bit , I have updated to the latest version 

pveversion -v 
pve-manager: 2.1-1 (pve-manager/2.1/f9b0f63a) 
running kernel: 2.6.32-11-pve 
proxmox-ve-2.6.32: 2.0-66

vzprocps: 2.0.11-2 
vzquota: 3.0.12-3 
pve-qemu-kvm: 1.0-9 
ksm-control-daemon: 1.1-1 



but I am still unable to start a kvm VM. I checked the boot process and noticed the kvm_amd module not being loaded. I googled this and found it is normally when virtualization is disabled in bios as is checked by the absence of vmx/svm in cpuinfo. None of this seems to be correct , as you can see svm is in cpuinfo 

egrep '(vmx|svm)' --color=always /proc/cpuinfo 
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good extd_apicid pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch lbrv

modprobe -vv kvm_amd 
insmod /lib/modules/2.6.32-11-pve/kernel/arch/x86/kvm/kvm-amd.ko 
FATAL: Error inserting kvm_amd (/lib/modules/2.6.32-11-pve/kernel/arch/x86/kvm/kvm-amd.ko): Operation not supported 

What else can I check , the machine has been powered off , cable unplugged so its not a rebooting issue. 

Thanks
