Subject: [PATCH] qemu_namespace: Introduce qemuDomainNamespaceSetupPath()
|
|
|
ab7a78 |
|
|
|
ab7a78 |
Sometimes it may come handy to just bind mount a directory/file
|
|
|
ab7a78 |
into domain's namespace. Implement a thin wrapper over
|
|
|
ab7a78 |
qemuNamespaceMknodPaths() which has all the logic we need.
