<devel@
lists.libvirt.org>:
Currently, only vendor/product and bus/device matching are
supported for USB host
devices. Neither of these provide a stable and persistent
way of assigning a guest
a specific host device. Vendor/product can be ambiguous.
Device numbers change on
every enumeration.
This patch adds a bus/port matching, which allows a specific
port on the host to be
specified using the dotted notation found in Linux's
"devpath" sysfs attribute.
The path series is based on the previous work of Thomas
Hebb: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/message/7U3HFUW3DGDOSF4RIBRZJINKFDYCE2ZH/
This resubmission includes Daniel's patch which extends the
USB hostdev test logic.
Maximilian Martin (7):
tests: validate an XML config with USB vendor/product set
virusb test data: add devpath files for port addressing
domain_conf, virhostdev, virusb, virusb test: add bus/port
matching
schema: add USB port attribute
tests: validate an XML config with USB bus/port set
nodedev: add USB port to nodedev XML
docs: add description for USB port matching
