Proxmox 4.0 questions

[lweidig]

I realize that many times this is not discussed prior to being here. However, I have need of getting a very recent version of qemu / kvm up and running so that we are able to put ESXi inside of a KVM system AND run a 64 bit operating system. We LOVE Proxmox, but currently with limited 3.x / 4.x kernel support there is not a new enough version to have the features needed to make this work. They seem to have been introduced in the 3.17+ kernels from a number of posts we have read.

I can run 32 bit OS'es in ESXi virtualized under KVM with the current 3.4 Proxmox, but that does not help us.


Also, just inquiring as we have a TON of OpenVZ machines running if there will be some sort of migration process for these or if we will need to start planning for a couple of pools.

Would even be willing to alpha test a new release at this point as we can dedicate hardware to this one application and leave it just running without other machines for a while.

Otherwise, and this is not desired can people suggest their favorite distro's for getting VERY new kernels and qemu / kvm support. We will probably just go with Ubuntu as we have a lot of familiarity with that and I do see the 4.x kernel available.

Thanks as always!

Hi,
I am not an expert but: even if it works, apart from the obvious overhead of having 1 VM into a virtual hypervisor running into a physical hypervisor,
You will have to manage those VMs with ESXi tools, even if you LOVE proxmox... including HA and backups
so I really can't guess what are the pros of this setup. except for testing/fun purposes. But it may be me, of course.

Yes, I realize all of those things. The purpose is that the application server we are needing to use ONLY supports running as a VMWare Image (well at least according to them, I intend to try and just run it KVM direct when it comes). So rather than dedicating the entire machine to this one application as I do not want to start running many other machines under ESXi this would be the ideal solution. The application has its own backup facilities so the that is taken care of. It is so close with the current Proxmox, but just needs some of the supported features in the latest Qemu/KVM (and therefore kernel) versions.

Hi,
About the Kernel we will stay on Redhat kernel current 3.10, but you can compile easy your own.
About OpenVz migration to PVE 4, there will be a solution to do this.
