Re: [libvirt] [PATCH 4/5] Add support for qemu's guestfwd

This patch allows the following to be specified in a qemu domain: <channel type='pipe'> <source path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> This will output the following on the qemu command line: -chardev pipe,id=channel0,path=/tmp/guestfwd \ -net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0 * docs/schemas/domain.rng: Add <channel> and <guestfwd> elements * proxy/Makefile.am: add network.c as dep of domain_conf.c * src/conf/domain_conf.[ch]: Add xml parsing/formatting for channel and guestfwd * src/qemu/qemu_conf.c: Add argument output for guestfwd * tests/qemuxml2(argv|xml)test.c: Add test for guestfwd domain syntax --- docs/schemas/domain.rng | 89 ++++++---- proxy/Makefile.am | 1 + src/conf/domain_conf.c | 189 ++++++++++++++++++-- src/conf/domain_conf.h | 6 + src/qemu/qemu_conf.c | 64 +++++++ .../qemuxml2argv-channel-guestfwd.args | 1 + .../qemuxml2argv-channel-guestfwd.xml | 26 +++ tests/qemuxml2argvtest.c | 4 +- tests/qemuxml2xmltest.c | 1 + 9 files changed, 332 insertions(+), 49 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-channel-guestfwd.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-channel-guestfwd.xml diff --git a/docs/schemas/domain.rng b/docs/schemas/domain.rng index 0a6ab61..b75f17e 100644 --- a/docs/schemas/domain.rng +++ b/docs/schemas/domain.rng @@ -930,6 +930,19 @@ definition doesn't fully specify the constraints on this node. --> <define name="qemucdev"> + <ref name="qemucdevSrcType"/> + <interleave> + <ref name="qemucdevSrcDef"/> + <optional> + <element name="target"> + <optional> + <attribute name="port"/> + </optional> + </element> + </optional> + </interleave> + </define> + <define name="qemucdevSrcType"> <attribute name="type"> <choice> <value>dev</value> @@ -944,43 +957,36 @@ <value>pty</value> </choice> </attribute> - <interleave> - <optional> - <oneOrMore> - <element name="source"> - <optional> - <attribute name="mode"/> - </optional> - <optional> - <attribute name="path"/> - </optional> - <optional> - <attribute name="host"/> - </optional> - <optional> - <attribute name="service"/> - </optional> - <optional> - <attribute name="wiremode"/> - </optional> - </element> - </oneOrMore> - </optional> - <optional> - <element name="protocol"> + </define> + <define name="qemucdevSrcDef"> + <optional> + <oneOrMore> + <element name="source"> <optional> - <attribute name="type"/> + <attribute name="mode"/> </optional> - </element> - </optional> - <optional> - <element name="target"> <optional> - <attribute name="port"/> + <attribute name="path"/> + </optional> + <optional> + <attribute name="host"/> + </optional> + <optional> + <attribute name="service"/> + </optional> + <optional> + <attribute name="wiremode"/> </optional> </element> - </optional> - </interleave> + </oneOrMore> + </optional> + <optional> + <element name="protocol"> + <optional> + <attribute name="type"/> + </optional> + </element> + </optional> </define> <!-- The description for a console @@ -1044,6 +1050,24 @@ <ref name="qemucdev"/> </element> </define> + <define name="guestfwdTarget"> + <element name="target"> + <attribute name="type"> + <value>guestfwd</value> + </attribute> + <attribute name="address"/> + <attribute name="port"/> + </element> + </define> + <define name="channel"> + <element name="channel"> + <ref name="qemucdevSrcType"/> + <interleave> + <ref name="qemucdevSrcDef"/> + <ref name="guestfwdTarget"/> + </interleave> + </element> + </define> <define name="input"> <element name="input"> <attribute name="type"> @@ -1158,6 +1182,7 @@ <ref name="console"/> <ref name="parallel"/> <ref name="serial"/> + <ref name="channel"/> </choice> </zeroOrMore> <optional>
