Question about the remote Authentication in the libvirt Java bindings
Dustin:
I am adding this response to the libvirt list as well so that others may
see it.
The authorization is done via a callback. The ConnectAuthDefault() that
you are using is one such implementation. You could create your own
subclass of ConnectAuth, and override the method:
public abstract int callback(Credential[] cred);
And then provide the username/password in that fashion. Look at the
ConnectAuthDefault in the case statement how it choos...

It could be interesting to try different libvirt drivers.
eg "test:///default"

JVM crashes during GC
Hi,
Could you tell me if the following is some known issue?
While performing the following simple test, I see my JVM crashing
(consistently):
1. Open a connection to an ESXi driver/host (passing ConnectAuthDefault
instance).
2. Close the connection.
3. Invoke GC
When GC is triggered, at some point, some unallocated native memory is
being tried to release. That's failing.
The error thrown is:
java(78745,0x70000241e000) malloc: *** error for object 0x7fd5df561390:
pointer being freed was not allocated...
