Subject: [PATCH] virsh: Make domif-setlink work more than once

In virsh, we have this convenient domif-setlink command, which is
|
|
|
735c6b |
just a wrapper over virDomainUpdateDeviceFlags() and which allows
|
|
|
735c6b |
setting link state of given guest NIC. It does so by fetching
|
|
|
735c6b |
corresponding <interface/> XML snippet and either putting
|
|
|
735c6b |
state=''/> into it, OR if the element already exists setting the
|
|
|
735c6b |
attribute to desired value. The XML is then fed into the update
|
|
|
735c6b |
API.
|
|
|
735c6b |
|
|
|
735c6b |
There's, however, a small bug in detecting the pre-existence of
|
|
|
735c6b |
the element and its attribute. The code looks at "link"
|
|
|
735c6b |
attribute, while in fact, the attribute is called "state".
