Re: [PATCH] virsh: Add source-initiator opt to build the initiator of pool XML

For iscsi-direct pool, the initiator is necessary for pool defining: <pool type="iscsi-direct"> ... <initiator> <iqn name="iqn.2013-06.com.example:iscsi-initiator"/> </initiator> ... </pool> Add --source-initiator to fill the initiator iqn for pool-create-as/pool-define-as subcommands. https://bugzilla.redhat.com/show_bug.cgi?id=1658082 Signed-off-by: Han Han <hhan(a)redhat.com&gt; --- docs/manpages/virsh.rst | 5 +++++ tools/virsh-pool.c | 17 +++++++++++++++-- 2 files changed, 20 insertions(+), 2 deletions(-) diff --git a/docs/manpages/virsh.rst b/docs/manpages/virsh.rst index 9187037a56..0482fe8b26 100644 --- a/docs/manpages/virsh.rst +++ b/docs/manpages/virsh.rst @@ -5732,6 +5732,7 @@ pool-create-as pool-create-as name type [--source-host hostname] [--source-path path] [--source-dev path] [--source-name name] [--target path] [--source-format format] + [--source-initiator initiator-iqn] [--auth-type authtype --auth-username username [--secret-usage usage | --secret-uuid uuid]] [--source-protocol-ver ver] @@ -5769,6 +5770,9 @@ the host file system.
