Description Jun Li 2014-01-20 09:04:42 UTC 
Description of problem:
qemu-kvm core dump when boot with 128  virtio-blk-pci data disks via PCIe-switch.
when boot with virtio-blk-pci data disks between 128 and 232, hit this issue too.
BTW, boot guest with system disk not under pcie-switch downstream. So this is different with bug 987322 and bug 1055416.
In this bug, can see seabios GUI and can boot guest. When booting guest kernel, qemu-kvm core dump.

Version-Release number of selected component (if applicable):
3.10.0-67.el7.x86_64
qemu-kvm-rhev-1.5.3-37.el7.x86_64
seabios-bin-1.7.2.2-6.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot guest as the following via multi-pcie.sh shell script.
# ./multi-pcie.sh 128
# cat script/multi-pcie.sh

Can you please test it again with 7.3? (it may be fixed already)

Hi Marcel
  
  Didn't reproduced the issue with kernel-3.10.0-350.el7.x86_64 and qemu-kvm-rhev-2.5.0-1.el7.test.x86_64, but hit another issue: guest didn't boot up with 12  virtio-blk-pci data disks via PCIe-switch.

The reproduced steps:
1.boot guest as the following via multi-pcie.sh shell script.
# ./multi-pcie.sh 12
# cat multi-pcie.sh
#!/bin/sh

MACHINE=q35
SMP=4,cores=2,threads=2,sockets=1

    then
        CLI="$CLI -device ioh3420,bus=pcie.0,id=root.$ustreamId,slot=$ustreamId"
        CLI="$CLI -device x3130-upstream,bus=root.$ustreamId,id=upstream$ustreamId"
    fi

   qemu-img create -f qcow2 /home/disk/disk$blkDiskId  100M

Actual result:
guest didn't boot up and didn't select the device which boot up, please check the pic through attachment
