# VM and devices for start-passthrough-vm.sh.
#
# Copy to conf/passthrough-vm.conf next to the scripts:
#   cp conf/passthrough-vm.conf.example conf/passthrough-vm.conf
#
# The script looks for it relative to its own location, so this works both in a
# checkout and deployed at /opt/ergosteur. Override with PASSTHROUGH_VM_CONFIG.
#
# Give the VM onboot: 0 so that Proxmox's own autostart leaves it alone, and
# point its hostpci entries at resource mappings rather than PCI addresses:
#   qm set <vmid> --onboot 0
#   qm set <vmid> --hostpci0 mapping=<mapping-id>,pcie=1

VMID=100

# One entry per resource mapping the VM uses: "<mapping-id> <lookup> <args>".
#
#   by-id <vendor:device:subvendor:subdevice>
#       Exactly one device in the host must have these IDs, and it must already
#       be on vfio-pci (or have no driver). Read them from sysfs:
#       cat /sys/bus/pci/devices/<addr>/{vendor,device,subsystem_vendor,subsystem_device}
#
#   by-netdev <interface> <mac> <vendor:device:subvendor:subdevice>
#       For one port of a multi-port NIC, where every port has the same IDs:
#       the device behind <interface>, which must be pinned to <mac> by a .link
#       file in /etc/systemd/network so that its name survives renumbering. Note
#       that the ports of one card need not share a subsystem ID; read it from
#       the port itself.
