@jalalsfs : unfortunately, still not able to reproduce the issue with dynamips, I'm guessing you're using it for IOS, if so, Cisco provide vIOS images with work perfectly in KVM - probably in other virt platforms too, however I only tested KVM.
NB. dynamips is not in proper fedora, this update is unrelated :)
It orphaned , I tried to fix the security bugs but upstream does not accept patches anymore.
There's a couple alternative lightweight httpd with static content support only (darkhttpd)
