Re: [libvirt] [PATCH 2/2] spice: expose the QEMU disable file transfer option

spice-server offers an API to disable file transfer messages on the agent channel between the client and the guest. This is supported in qemu through the disable-agent-file-xfer option. This patch exposes this option to libvirt. Adds a new element 'filetransfer', with one property, 'filetransfer', which accepts a boolean setting. Default is enabled. Depends on the capability exported in the first patch of the series. --- docs/formatdomain.html.in | 8 +++++ docs/schemas/domaincommon.rng | 11 ++++++ src/conf/domain_conf.c | 31 ++++++++++++++++- src/conf/domain_conf.h | 10 ++++++ src/libvirt_private.syms | 2 ++ src/qemu/qemu_command.c | 9 +++++ ...emuxml2argv-graphics-spice-agent-file-xfer.args | 9 +++++ ...qemuxml2argv-graphics-spice-agent-file-xfer.xml | 40 ++++++++++++++++++++++ .../qemuxml2argv-graphics-spice.args | 5 +-- .../qemuxml2argv-graphics-spice.xml | 1 + tests/qemuxml2argvtest.c | 9 ++++- 11 files changed, 131 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-agent-file-xfer.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-agent-file-xfer.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 68860ef..c11a7d3 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4042,6 +4042,7 @@ qemu-kvm -net nic,model=? /dev/null &lt;streaming mode='filter'/&gt; &lt;clipboard copypaste='no'/&gt; &lt;mouse mode='client'/&gt; + &lt;filetransfer enable='no'/&gt; &lt;/graphics&gt;</pre> <p> Spice supports variable compression settings for audio, @@ -4081,6 +4082,13 @@ qemu-kvm -net nic,model=? /dev/null <span class="since">since 0.9.11</span>.
