Wed Jan 26 00:36:58 UTC 2011
* src/qemu/qemu_command.c (qemuBuildCommandLine): Emit smartcard
options.
(qemuAssignDeviceAliases): Assign an alias for smartcards.
(qemuBuildControllerDevStr): Manage the usb-ccid controller.
* tests/qemuxml2argvtest.c (mymain): Add new tests.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-host.args: New
file.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-host-certificates.args:
Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-passthrough.args:
Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-controller.args:
Likewise.
Notes:
v2: new patch
v3: reject ',' in cert name, alias for host smartcard use, output
usb-ccid controller separate from rest of command line, enforce at
most one smartcard for now
