My system:

#uname -a

Linux hostname 3.13.0-57-generic #95-Ubuntu SMP Fri Jun 19 09:28:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I am trying build a VM ( https://help.ubuntu.com/community/KVM/CreateGuests ) with this command:

#ubuntu-vm-builder kvm trusty --libvirt qemu:///system

But in the end it fails with this error:

Unpacking linux-image-virtual (3.13.0.58.65) ...

, stderr: grep: /proc/cpuinfo: No such file or directory

**This kernel does not support a non-PAE CPU.**

Looks like I do have a PAE CPU...

 #grep -i PAE /proc/cpuinfo

 flags      : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36

I want to build and host KVM VMs on this server. What am I doing wrong?

UPDATE: I am testing it with --addpkg linux-image-generic
