Most likely seabios is running out of low memory. Can you retest with 1.7.5 rebase builds please? http://people.redhat.com/ghoffman/bz1101500/ (In reply to Gerd Hoffmann from comment #3) > Can you retest with 1.7.5 rebase builds please? > http://people.redhat.com/ghoffman/bz1101500/ Retest with above builds(http://people.redhat.com/ghoffman/bz1101500/), guest can boot up successfully with the same cli as comment #0. # rpm -qa|grep seabios seabios-1.7.5-0.rc1.el7_0.bz1101500.1.x86_64 seabios-bin-1.7.5-0.rc1.el7_0.bz1101500.1.x86_64 Best Regards, Jun Li reproduce this bug with seabios-1.7.2.2-10.el7.x86_64 & qemu-kvm-1.5.3-60.el7.x86_64. according to comment0's steps. #sh 4230877-pcie-capability-of-usb-xhci-to-rc.sh 22 result: 1.HMP output Press F12 for boot menu.
