[pve-devel] Proxmox VE 4.0 released!

[Alexandre DERUMIER]

>>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.
