666threesixes666 Posted July 9, 2015 Report Share Posted July 9, 2015 i think you generate entropy on the host then import it to the vm. other tips ive seen are to generate the crypto data then import the data to the vm/server in the wild. i've tinkered with fortuna and csprng https://code.google.com/p/csrng/ i haven't posted this info to the wiki because im not done and haven't tested it under useful conditions. which vm software are you using?

hydrapolic Posted July 17, 2015 Author Report Share Posted July 17, 2015 Hello, I'm using the Funtoo Linux Hosting virtual machine - that is OpenVZ. Entropy can be imported, but it must be generated on demand, because it will eventually drain. Linux itself generates entropy (hw interrupts, keyboard, network), but it's not enough if you have a busy SSL machine. Link to comment Share on other sites More sharing options...
hydrapolic Posted August 12, 2015 Author Report Share Posted August 12, 2015 Fixed by @drobbins by installing haveged on the virtualization machines. Thanks for it! :) Link to comment Share on other sites More sharing options...
