conf: permit auto-assignment of controller indexes Hand-entering indexes for 20 PCI controllers is not as tedious as manually determining and entering their PCI addresses, but it's still annoying, and the algorithm for determining the proper index is incredibly simple (in all cases except one) - just pick the lowest unused index. The one exception is USB2 controllers because multiple controllers in the same group have the same index. For these we look to see if 1) the most recently added USB controller is also a USB2 controller, and 2) the group *that* controller belongs to doesn't yet have a controller of the exact model we're just now adding - if both are true, the new controller gets the same index, but in all other cases we just assign the lowest unused index. With this patch in place and combined with the automatic PCI address assignment, we can define a PCIe switch with several ports like this: <controller type='pci' model='pcie-root-port'/> <controller type='pci' model='pcie-switch-upstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> ... These will each get a unique index, and PCI addresses that connect them together appropriately with no pesky numbers required.

qemu: command: Override HOME variable for system QEMU By default, qemu user's home dir points to '/' which shouldn't be used at all. We therefore pass the HOME variable from the current variable iff not running as SUID, which means that for systemd we never set it. This patch makes sure, that for system QEMU this is always set to libDir/<driver>, session mode is left untouched. Signed-off-by: Erik Skultety <eskultet@redhat.com> Reviewed-by: Daniel P.

qemu: assign nec-xhci (USB3) controller to a PCIe address when appropriate The nec-usb-xhci device (which is a USB3 controller) has always presented itself as a PCI device when plugged into a legacy PCI slot, and a PCIe device when plugged into a PCIe slot, but libvirt has always auto-assigned it to a legacy PCI slot. This patch changes that behavior to auto-assign to a PCIe slot on systems that have pcie-root (e.g. Q35 and aarch64/virt). Since we don't yet auto-create pcie-*-port controllers on demand, this means a config with an nec-xhci USB controller that has no PCI address assigned will also need to have an otherwise-unused pcie-*-port controller specified: <controller type='pci' model='pcie-root-port'/> <controller type='usb' model='nec-xhci'/> (this assumes there is an otherwise-unused slot on pcie-root to accept the pcie-root-port)

The main advantage is that arguments for an option are always on the same line which makes it more easy to see what changed in a diff and prevents re-wrapping of the line if a wrapping point moves over the threshold. Additionally the used output is the same we have in the VM log file when a VM is starting.

qemu: assign nec-xhci (USB3) controller to a PCIe address when appropriate The nec-usb-xhci device (which is a USB3 controller) has always presented itself as a PCI device when plugged into a legacy PCI slot, and a PCIe device when plugged into a PCIe slot, but libvirt has always auto-assigned it to a legacy PCI slot. This patch changes that behavior to auto-assign to a PCIe slot on systems that have pcie-root (e.g. Q35 and aarch64/virt). Since we don't yet auto-create pcie-*-port controllers on demand, this means a config with an nec-xhci USB controller that has no PCI address assigned will also need to have an otherwise-unused pcie-*-port controller specified: <controller type='pci' model='pcie-root-port'/> <controller type='usb' model='nec-xhci'/> (this assumes there is an otherwise-unused slot on pcie-root to accept the pcie-root-port)

conf: permit auto-assignment of controller indexes Hand-entering indexes for 20 PCI controllers is not as tedious as manually determining and entering their PCI addresses, but it's still annoying, and the algorithm for determining the proper index is incredibly simple (in all cases except one) - just pick the lowest unused index. The one exception is USB2 controllers because multiple controllers in the same group have the same index. For these we look to see if 1) the most recently added USB controller is also a USB2 controller, and 2) the group *that* controller belongs to doesn't yet have a controller of the exact model we're just now adding - if both are true, the new controller gets the same index, but in all other cases we just assign the lowest unused index. With this patch in place and combined with the automatic PCI address assignment, we can define a PCIe switch with several ports like this: <controller type='pci' model='pcie-root-port'/> <controller type='pci' model='pcie-switch-upstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> <controller type='pci' model='pcie-switch-downstream-port'/> ... These will each get a unique index, and PCI addresses that connect them together appropriately with no pesky numbers required.

qemu: caps: Always assume presence of 'ide-hd' and 'ide-cd' devices The split of ide-disk into the two separate devices was introduced by qemu commit 1f56e32a7f4b3 released in qemu v0.15. Note that when compared to the previous commit which made sure that no disk related tests were touched, in this case it's not as careful. Signed-off-by: Peter Krempa <pkrempa@redhat.com>
