I look after a number of CentOS 4.x servers running legacy applications that depend on ancient versions of various things (such as MySQL 3.x) and which can't be upgraded without non-trivial development effort.
I've been considering virtualising them and as a test have been trialling with a company that uses Parallels Cloud Server 6.
However, I've run into a roadblock in that the Parallels Tools installer in PCS6 require a version of glibc higher than that which is available in CentOS 4.x (v2.5 required versus v2.3.4 installed).
Without the guest OS tools installed it's impossible to migrate a VM from node to node or back it up without shutting the VM down first, which is less than useful.
If you are running physical machines now, you don't have that ability anyway...
So I have two questions:
- Does anyone know if there is a version of the PCS6 Tools built
against glibc 2.3.4 available anywhere?
- Is there an alternative virtualisation environment I should be
looking at which fully supports CentOS 4.x as a guest OS? And if so, does anyone have recommendations for a hosting supplier that offers that environment (ideally UK based).
Does it have to be hosted? You could run under KVM/Virtualbox/Vmware, etc. on your own hardware. If you have any internet exposure you can't expect to survive long without update support, though.

True, but that's a reason to try and migrate to a better environment which would allow it.

Yes, it has to be hosted. Aiming to get away from having to own physical hardware with all that entails support-wise.
