Sometimes we need to resurrect an old VM to help simulate a live physical setup to migrate data and functionality and hence this attempt. If any user has a template for LXC that has Oracle 11.2.0.4 installed in it with Apache Tomcat and webapps running it would be useful as most Oracle Linux Server 5.8 links are dead now, not even in the official mirrors.
Yes, this is primarily a guest issue, but the community can share experience on the use case of Proxmox in such instances. There are issues with control of Oracle Linux Server 5.x in PVE6+ as LXC/KVM. In KVM we have Mouse synch issues and no way to yum install gpm and it's ilk.
