I have noticed the below error when one day i was starting up my KVM virtual machines to play around with Docker Swarm.

error: internal error: process exited while connecting to monitor: qemu: could not load PC BIOS 'bios-256k.bin'

There wasn't much information on google or forums and most talked about symlinks that weren't there. Most folks recommended reinstalling seabios and seabios-bin. But unfortunately, reinstalling these packages did not provide the necessary files.

Upon further inspection of the package versions, I noticed that seabios-1.8.2-1.el7 does not provide /usr/share/seabios/bios-256k.bin. Now seabios-bin-1.7.5-11.el7 does provide that file.

Make sure that you are installing seabios-1.7.5-11.el7 and seabios-bin-1.7.5-11.el7. Check that you do not have /etc/yum.repos.d/CentOS-Xen.repo enabled. These packages should be pulled from http://mirror.centos.org/centos/7/virt/x86_64.
