Line 1: Line 1:
 +This error indicates that the cryptographic random bit generator could not be initialised. ​ This usually indicates that there is no good source of entropy available.
  
 +There is a known bug in the Microsoft Hyper-V hypervisor (as used for Microsoft Azure virtual machines), in which the emulated CMOS RTC hardware seems to be incapable of generating an interrupt. ​ This breaks the entropy generation mechanism used by iPXE, and will result in this error. ​ There are some indications that this problem affects only AMD hardware, though this has not been proved conclusively. ​ If you are using Microsoft Azure, then you may be able to work around the problem by using a larger instance (which is more likely to use an Intel CPU).
