Re: [libvirt PATCH v5 27/32] schema: add password configuration for ssh disk

Right now, ssh network disks are not usable. There is some basic support in libvirt that is meant to support disk chains that have backing disks located at ssh urls, but there is no real way for a user to configure a ssh-based disk. This commit allows users to configure an ssh disk with password authentication. Implementation will follow. <disk type='network'> <source protocol='ssh' ...> <auth username='myusername'> <secret type='iscsi' usage='secretname'/> </auth> </disk> Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com&gt; --- docs/formatdomain.rst | 27 ++++++++++++++------------- src/conf/schemas/domaincommon.rng | 23 ++++++++++++++++++++++- 2 files changed, 36 insertions(+), 14 deletions(-) diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index 36c6d87907..bf071255c5 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -2718,7 +2718,7 @@ paravirtualized driver is specified via the ``disk`` element. ``network`` The ``protocol`` attribute specifies the protocol to access to the requested image.
