Re: [libvirt] [PATCHv5 6/9] spicevmc: support new qemu chardev

From: Daniel P. Berrange <berrange(a)redhat.com&gt; Inspired by https://bugzilla.redhat.com/show_bug.cgi?id=615757 Add a new character device backend for virtio serial channels that activates the QEMU spice agent on the main channel using the vdagent spicevmc connection. The <target> must be type='virtio', and supports an optional name that specifies how the guest will see the channel (for now, name must be com.redhat.spice.0). <channel type='spicevmc'> <target type='virtio'/> <address type='virtio-serial' controller='1' bus='0' port='3'/> </channel> * docs/schemas/domain.rng: Support new XML. * docs/formatdomain.html.in: Document it. * src/conf/domain_conf.h (virDomainChrType): New enum value. * src/conf/domain_conf.c (virDomainChr): Add spicevmc. (virDomainChrDefParseXML, virDomainChrSourceDefParseXML) (virDomainChrDefParseTargetXML): Parse and enforce proper use. (virDomainChrSourceDefFormat, virDomainChrDefFormat): Format. * src/qemu/qemu_command.c (qemuBuildChrChardevStr) (qemuBuildCommandLine): Add qemu support. * tests/qemuxml2argvtest.c (domain): New test. * tests/qemuxml2argvdata/qemuxml2argv-channel-spicevmc.xml: New file. * tests/qemuxml2argvdata/qemuxml2argv-channel-spicevmc.args: Likewise.
