I'm looking for something between that of Proxmox VE and Red Hat Enterprise Linux Virtualization. FuncMan aka upcoming web-based management system and OpenNode main idea is to keep things simple as Proxmox but to use RHEL/CentOS stable codebase and implement some things what Proxmox is missing (for example softraid, stable RHEL kernel, management through libvirt if possible, etc.) > > === Proxmox VE === > It is dead easy to install and use... and it works well... but it lacks the following features: > > 1) KVM VM image management - It would be nice if one could create a VM and use the storage as a base image for other VMs. We are already working on KVM templates to use with OpenNode. We had to create our own template package format (it will be simple tar) to contain besides VM filesystem other needed things - like VM configuration template. > > 2) Tiered user access - It would be nice to give ownership of a VM to a user and let them have some web-based management of it This can happen in future but it should be implemented as separate web panel for VM users probably.

Red Hat open sourced SPICE in January but so far no one has been able to incorporate mhm..need to get more familiar with this. > > == RHEV for Servers === > It claims to have all of the features missing in Proxmox VE BUT it has a number of major annoyances: > > 1) Windows-based Management app - To install their management app you have to put it on a Windows 2000 Server. It uses Microsoft SQL server as a storage back end, Microsoft IIS server as the web-server, and .Net technology for the management app. It requires Microsoft Internet Explorer to connect to the management app. Red Hat is in the process of completely rewriting the management app as a Jboss application but it will be some time before that is available I thought that Red Hat was cooking Ovirt as their next-gen manager. No OpenVZ support still. > > 2) The management app is very error prone and buggy - Granted, the hardware configuration / network I used it on wasn't ideal but it should have worked much better than it did. I was using NFS storage and I was constantly having issues with storage disappearing. Talking to friends it seems to be pretty painful to use with iSCSI targets too. The current management app is just to fragile and error prone to be useful... at least for me. > > 3) The feature set is there but the complexity it adds seems to almost require a very expensive hardware configuration to take advantage of those features. Ovirt also has kind a too complex requirements to start using in smaller datacenters - complex separate storage pool setups etc. > > === OpenNode === > > KVM and LVM provide a lot of functionality... but how does the shared storage need to be implimented to use it? Will one need a clustered filesystem in a clustered machine environment... or will something as open as DRBD work? First goal is to implement local storage management (LVM LV-s, file based images) on OpenNode. After that probably NFS, iSCSI, etc - for shared storage. It should be possible already to manually configure OpenNode for NFS, iSCSI, SAN - like any other RHEL/CentOS host. > > What features will OpenNode offer that Proxmox VE is missing and that RHEV has? Red Hat has not released RHEV for Desktops yet but that is on the roadmap. Will OpenNode offer anything in the way of VDI? Will it offer SPICE remote display capability? OpenNode is currently concentrating on servers virtualization - as VDI is still very much evolving concept. Also KVM IO perfomance is still not ready for serious production use - imagine several Windows VM-s to be used as desktops...I think max 2 VM-s per CPU core is not really appealing and disk IO is way too slow in our tests.. For virtualizing linux desktops we use LTSP OpenVZ template for example. One thing we have in mind is to use FuncMan for not only VM (virtualization) management but also for services management inside VM-s or physical hosts (Samba, Apache, DHCP, etc). So FuncMan could be as general management interface for all server infrastructure. > > I'm sure a lot of people want to know the answers to these questions. :) > > Thanks in advance and TYL, > -- > Scott Dowdle > 704 Church Street > Belgrade, MT 59714 > (406)388-0827 [home] > (406)994-3931 [work] > > ------------------------------------------------------------------------------ > Download Intel® Parallel Studio Eval > Try the new software tools for yourself.
