My CPU is reported by Intel to support the AES-NI native instructions. http://ark.intel.com/products/65707
However, /proc/cpuinfo does not list the aes flag (which is what I guess is preventing me from installing the aesni-intel kernel module -- my ultimate goal is to have dm-crypt use the benefits of HW acceleration).
VT-d and VTx is enabled on BIOS but according to flags is not. Also before I use virtualization with vmware. I try to use XEN HVM now. According to my cpuinfo I can't because vmx flag is not preset. I'm not understand why.
I want to install kvm on my desktop PC to learn virtualization, my cpu is intel Core i3, and I found it support VT-x on intel's page, I also enabled virtualization in BIOS,
however, I cann't find vmx flag from /proc/cpuinfo.
I have intel celeron d 3.06ghz processor . Now I am using 32 bit Ubuntu and I wish to upgrade to 64 bit Ubuntu if my processor allow. My doubt is how to identify 64 bit processor with cat /proc/cpuinfo command. it shows
How can I tell whether my processor has a particular feature? (64-bit instruction set, hardware-assisted virtualization, cryptographic accelerators, etc.) I know that the file /proc/cpuinfo contains this information, in the flags line, but what do all these cryptic abbreviations mean?
For example, given the following extract from /proc/cpuinfo, do I have a 64-bit CPU?
