I am trying to connect to the virtualbox hypervisor through libvirt java
binding.
I am on Ubuntu 10.04 and I have installed libvirt-0.85, libvirt-java-0.4.6
and virtualbox-ose-dkms. I have configured libvirt project and its java
binding at Eclipse and the default test of the binding runs properly. When I
try to run a simple test in java with the connection:
conn = new Connect("vbox:///session", false)
I get the following exception: "exception caught:org.libvirt.
LibvirtException: Failed to start the nwfilter driver: Is the daemon running
?"
If I try to do the same thing, but instead of using the java biding I use
virsh, it works. I am able to connect and start the virtual machine
successfully, although none of the nwfilter commands work in virsh.
(The nwfilter-list command shows this error: Failed to list network
filters. This function is not supported by the connection driver:
virConnectNumOfNWFilters)
If I run the same java test using the Test hypervisor connection, things
work properly.
I don't know if I have to install or configure something else in order to
get the nwfilter working or if virtualbox doesn't provide support for it,
and if it doesn't provide, how can I get rid of this exception and use
virtualbox virtual machine connection through java binding ?
My objective is being able to use libvirt library commands in a software (in
java) which uses virtualization to run jobs in different machines, but
without the connection to the hypervisor I can't do anything.
I apologize if this question has been already answered. I have tried hard to
get the answers for it looking at forums and also in the discussions of this
list, but I couldn't.
What am I missing?
Thanks!
