Hi,
I'm using QEMU (2.1.50) with Fedora 20 based host (3.15.6-200). While
doing PCI-passthrough of PMC-Sierra 8001 SAS adapter, the *host* does a
hard lockup even before guest kernel starts running. BIOS in use is
SeaBIOS 1.7.5. Despite enabling various debugging options, I do not see
any messages on the serial console.
The device is detached from host driver and bound to pci-stub, followed
by this command -
qemu-system-x86_64 guest.img --enable-kvm -smp
14,sockets=2,cores=7,threads=1 -nographic -device pci-assign,host=b:d:f
This device works fine with host, similarly other devices I have work
fine with guest through pci-pt. Any pointers to debug further will be
greatly appreciated.
Thanks,
nt
