Subject: [Qemu-devel] Hang using PXB w/ DMI-PCI w/ PCI bridge
Date: Tue, 4 Oct 2016 15:57:24 +0100 [thread overview]
Message-ID: <20161004145724.GN5578@redhat.com> (raw)
With the following command line, the guest will hang, with
no output displayed at all - not even the BIOS displays:
qemu-system-x86_64 \
-machine accel=kvm \
-name guest=f23x86_64,debug-threads=on \
-machine pc-q35-2.6,accel=kvm,usb=off,vmport=off \
-m 8000 \
-smp 8,sockets=8,cores=1,threads=1 \
-numa node,nodeid=0,cpus=0-3,mem=4000 \
-numa node,nodeid=1,cpus=4-5,mem=2000 \
-numa node,nodeid=2,cpus=6-7,mem=2000 \
-uuid ac4c9e05-6137-4bde-a33a-5c3623f44fb2 \
-no-user-config \
-nodefaults \
-device sga \
-device i82801b11-bridge,id=pci.1,bus=pcie.0,addr=0x1e \
-device pci-bridge,chassis_nr=2,id=pci.2,bus=pci.1,addr=0x0 \
-device pxb-pcie,bus_nr=214,id=pci.3,numa_node=0,bus=pcie.0,addr=0x2 \
-device pxb-pcie,bus_nr=234,id=pci.4,numa_node=1,bus=pcie.0,addr=0x3 \
-device pxb-pcie,bus_nr=254,id=pci.5,numa_node=2,bus=pcie.0,addr=0x4 \
-device i82801b11-bridge,id=pci.6,bus=pci.3,addr=0x0 \
-device i82801b11-bridge,id=pci.7,bus=pci.4,addr=0x0 \
-device i82801b11-bridge,id=pci.8,bus=pci.5,addr=0x0 \
-device pci-bridge,chassis_nr=9,id=pci.9,bus=pci.6,addr=0x0 \
-device pci-bridge,chassis_nr=10,id=pci.10,bus=pci.7,addr=0x0 \
-device pci-bridge,chassis_nr=11,id=pci.11,bus=pci.8,addr=0x0 \
-netdev user,id=hostnet0 \
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:9f:58:3c,bus=pci.2,addr=0x1 \
-chardev stdio,id=charserial0 \
-device isa-serial,chardev=charserial0,id=serial0 \
-display none
Removing both the 3rd and 4th pci-bridge devices (id=pci.10 & pci.11)
fixes it.
I'm unclear if this is a mistake in my configuration, or a bug
in QEMU or a bug in SeaBIOS ?
Regards,
Daniel
