Subject: [libvirt-users] How can I open a libvirt remote connection

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.
How can I connect to libvirtd with ssh automatically? No need to type the password
manually.
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);
Thanks,
Kevin

Libvirt has to spawn an external SSH process for +ssh URIs, so we can't hook
it up into our auth callbacks.

You need to setup SSH public keys + SSH agent

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

[Wangkai (Kevin,C)]
Which type of URI can be hooked by auth callback? Qemu+tls?

Maybe I will try this later.

Just use SSH public key authentication with an empty passphrase, just
as you would with any other automated SSH connection.

with reboot you may choose what mode do you want to use:
'acpi', 'agent', 'initctl' or 'signal'
By default, ACPI is used, meaning an ACPI event is send to the guest.
However, when there is no acpid running, this event is silently ignored.
So you have two options:
1) install acpid into the guest
2) use a different method.

It should be stored in '/var/log/libvirt/qemu/fc18guest5.log'. If
there's nothing related, look for errors in
'/var/log/libvirt/libvirtd.log'.

I don't think it has anything to do with the fact that there is a
newline between '-device' and 'scsi-cd'. That's just debug output
of
virt-install.

Command 'virsh list' (by default) lists only running domains, try adding
'--all' as a parameter.
