Description Sitong Liu 2017-04-12 07:08:43 UTC 
Description of problem:
Boot RHEL7.4 guest with ivshmem-plain and virtio-blk-pci and the latest seabios-1.10.2-2.el7.x86_64. Guest kernel can not be loaded. I added a guest screen to attachment. If boot guest with ide-driver+seabios-1.10.2-2.el7.x86_64. guest works well.

QE also tested previous seabios version(seabios-1.9.1-5.el7.x86_64). Guest work well. According to bug 1373154, This issue has been fixed with seabios-1.9.1-5.el7.x86_64 before. So it is a regression bug. 

Version-Release number of selected component (if applicable):
seabios-1.10.2-2.el7.x86_64
qemu-kvm-rhev-2.9.0-0.el7.mrezanin201703210848.x86_64
3.10.0-648.el7.x86_64


How reproducible:
100%
