Hi Jonathan,
I sent an email yesterday on the qemu ML.
"
Please can you try using
qemu-system-arm -machine virt,highmem=off -m 1024M -kernel zImage
-serial stdio
Does your guest support LPAE? This may be the cause.
Thanks
Eric

Title:
Default arm virt machine broken
Status in QEMU:
New
Bug description:
This occurs on qemu_v3.0.0 but not on qemu_v2.12.2 (built from
qemu_v3.0.0 tag on github)
Symptom: You'll see something like this in the kernel output:
[ 1.285210] OF: PCI: host bridge /address@hidden ranges:
[ 1.286246] OF: PCI: IO 0x3eff0000..0x3effffff -> 0x00000000
[ 1.287061] OF: PCI: MEM 0x10000000..0x3efeffff -> 0x10000000
[ 1.287820] OF: PCI: MEM 0x8000000000..0xffffffffff -> 0x8000000000
[ 1.289312] pci-host-generic 4010000000.pcie: can't claim ECAM area [mem
0x10000000-0x1fffffff]: address conflict with /address@hidden [mem
0x10000000-0x3efeffff]
[ 1.290984] pci-host-generic: probe of 4010000000.pcie failed with error
-16
Qemu Command Line: qemu-system-arm -machine virt -m 1024M -kernel
zImage -serial stdio
I can post my zImage if anyone has problems reproducing with their own
zImage.
Note that this problem breaks pci making the machine unusable.
