I have worked quite a bit with different Java applications and Proxmox. Â While you can get things to work, I found it easier to just use KVM under Proxmox for Java applications. Â You may use a few more resources, but you have more stability and more of a bare metal machine environment, especially when the application experiences loads. Â Java is just hard to work around sometimes. Â However, with Proxmox, everything works exactly the same just about whether it is a container or KVM. Â I initially tried everything with the OpenVZ container, but soon grew tired of troubleshooting and tweaking every application and just went the KVM route with Java apps.<div>

</div>We have 1GB allocated to our smallest container which also runs a Java<br>
application, albeit not Alfresco, and it worked fine on Lenny/amd64, with Sun<br>
Java 6 underneath.<br>
<br>
Anyway, yeah, that is the sort of tuning I was talking about. :)<br>
<br>
Er, I don't actually know, but you might need to use a veth device rather<br>
than a venet device for the Alfresco SMB share thing to work. Â If that is the<br>
document management thingy which does SMB/CIFS sharing, that is. :)<br>
