Created attachment 1288307 [details] guest xml Description of problem: Start guest with the xml in the attachment. Reboot guest, qemu will crash. The error message from qemu log: qemu-kvm: hw/nvram/fw_cfg.c:879: fw_cfg_modify_file: Assertion `index < fw_cfg_file_slots(s)' failed. 2017-06-14 12:43:27.809+0000: shutting down, reason=crashed Version-Release number of selected component: libvirt-3.2.0-10.el7.x86_64 qemu-kvm-rhev-2.9.0-10.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Define a guest with xml in the attachment. # virsh define rhel7.3.xml 2.Start guest: # virsh start rhel7.3 3.After guest boots up fully, reboot guest: # virsh reboot rhel7.3 Actual results: qemu crash when reboot guest Expected results: qemu doesn't crash Additional info: 1. Change machine type to pc-i440fx-rhel7.4.0, can't reproduce. 2. Delete any one of the following elements from xml, can't reproduce: 1) <bootmenu enable='yes' timeout='3000'/> 2) <bios useserial='yes' rebootTimeout='0'/> 3) <maxMemory> and <numa>.... 4) <controller type='pci' index='1' model='pci-expander-bus'>... 5) <panic model='isa'> 3. This is NOT a regression, I can reproduce on RHEL7.3.z: qemu-kvm-rhev-2.6.0-28.el7_3.10.x86_64
