Rohit Yadav commented on CLOUDSTACK-1643:
-----------------------------------------
The module loading will fail, but won't be fatal... I can add rule/script that
during each startup/reboot it can check and load the module.
But, if we enable the module and hot migrate it, it can fail as the underlying
HVM changed to a processor that does not support intel aes ni instructions.
> Virtual Router should include AES NI (Advanced Encryption Standard
> Instruction Set) support

> Crypto routines (such as VPN and SSL) that use these instructions run up to
> 10 times faster.
> The fix would be check if aes_intel is available (modprobe) and load it.
