>>Quick questions - can 3.4 nodes coexist with 4.0 nodes on a cluster? 

3.4 nodes will not see 4.0 nodes.

It's possible to upgrade all nodes to jessie/proxmox 4.0, at the same time,
without reboot host. (and without stop the vms)

Then live migration is possible. (and reboot host when it's node)

I have sent a mail some months ago about it, but I need to test it again.

Woot! and Wow! 

Quick questions - can 3.4 nodes coexist with 4.0 nodes on a cluster? 

I did see that you can't live migrate VM's from one to the other.

Hi all! 

We are proud to announce the final release of our Proxmox VE 4.0 - based on the great Debian Jessie. 

Watch our short introduction video - What's new in Proxmox VE 4.0? 

Linux Containers (LXC) 

The new container solution for Proxmox VE is fully integrated into our frameworks, e.g. this includes our advanced storage plugins like ZFS, Ceph or even DRBD9, full IPv6 support and much more. LXC works with all modern and latest Linux kernels. 

Bash completion 

All our CLI tools support now advanced bash completion, Linux experts will just love it! 

New Proxmox VE HA Manager for High Availability Clusters 

The new HA manager dramatically simplifies HA setups – it works with only a few clicks on the GUI, test it! And it elminates the need of external fencing devices, watchdog fencing is automatically configured. 

Important wiki articles and release notes
