Hi,
When I use 'virConnectOpenAuth' function to connect to '192.168.1.102'
libvirtd with ssh,
Code below, the screen print the dialog "root(a)192.168.1.102's password:" ,
and only
After I type the password, the connection can be created.
Libvirt has to spawn an external SSH process for +ssh URIs, so we can't hook
it up into our auth callbacks.
How can I connect to libvirtd with ssh automatically? No need to type
the password manually.
You need to setup SSH public keys + SSH agent
char *au[2] = {"root", "xxxx"};
virConnectAuth auth = {
credTypes,
sizeof(credTypes) / sizeof(int),
virConnCb,/* callback function, actually was not be called after
connect*/
au /* user and password */
};
conn = virConnectOpenAuth("qemu+ssh://192.168.1.102/system", &auth, 0);
virConnectOpenAuth() doesn't do anything useful for '+ssh' URIs.
There is however a alternative 'libssh2' URI that does use the
callbacks. eg qemu+libssh2://hostname/system
This is less tested & potentially buggy, but it might be ok for your needs

Daniel
