I need to be able to install new virtual machines with Oracle VM. There's console button in the web interface which opens VNC connection to specified Virtual guest but it haven't been able to get it to work yet.

There's some info available here: http://oss.oracle.com/oraclevm/manag...README-console

I converted the rpm to tgz package and installed it. It installs the packages to /opt.

I also tried info in the following link:

Firefox's about:config lists the ovm-console plugin active and when I press the console button in the web page it opens up a new window. The window doesn't prompt for missing plugin but it won't open the VNC display either.

Any ideas how to get this thing working?

As an alternative I installed tigervnc from Aliens repo but it has problems with the mouse cursor. My laptop mouse cursor goes at different pace than the vnc client cursor so it makes its use very hard.

Edit, forgot to mention that I checked and tightvnc-java package is installed on the Oracle VM manager and the console button works on Windows and on Fedora when I tried it. So the issue seems to be limited to my Slackware64 setup.

While this isn't a solution, here's what I'd try:

Try to identify the differences between the environment of a working installation and yours (e.g., Fedora vs. Slackware). Pay especial attention to the PATH and CLASSPATH variables if they are present.

IIRC, rpm2tgz doesn't perfectly figure out post-install scripts. I'd pull apart the rpm to see what any post-install setup scripts do and make sure to do the equivalent on the Slackware machine.

Hmm, I don't know if anyone else is running linux at office and using the Oracle VM. I could install virtual client with fedora and test the differences.

Ah, good catch. Gotta see if the rpm does some installation magic to make the plugin work.

Would firefox output any log for plugin errors? I tried to browse ~/.mozilla but couldn't pinpoint anything.

Sorry, I don't know that. I'm not a java dev/web dev/heavy app user. I'm just a lowly windows dev. ;v)

ISTR, though, some sort of java console thingy you can run in the browser. I don't know if that would help.

Okay, just checked the post-install script but it only makes the symlink which exists on my system.

I think Java isn't the issue here as it is only running on the server-side and it appears to work.
The issue is with the local VNC plugin which isn't Java based.
