Re: [libvirt] [PATCH] Allow a HTTP URL for cdrom ISO image

From: Aline Manera <alinefm(a)br.ibm.com&gt; QEMU/KVM already allows an HTTP URL for the cdrom ISO image so add this support to libvirt as well. The xml should be as following: <disk type='network' device='cdrom'> <source protocol='http' name='/url/path'> <host name='host.name' port='80'/> </source> </disk> Signed-off-by: Aline Manera <alinefm(a)br.ibm.com&gt; --- src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 7 ++++ .../qemuxml2argv-disk-cdrom-network.args | 5 +++ .../qemuxml2argv-disk-cdrom-network.xml | 37 ++++++++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 6 files changed, 54 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-cdrom-network.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-cdrom-network.xml
