We just released Proxmox VE 3.0. Its based on the great Debian 7.0 release (Wheezy) and introduces a great new feature set:

VM Templates and Clones

Under the hood, many improvements and optimizations are done, most important is the replacement of Apache2 by our own event driven API server.

A big Thank-you to our active community for all feedback, testing, bug reporting and patch submissions.

Release notes


Upgrade from any 2.3 to 3.0

Install Proxmox VE on Debian Wheezy

Best regards,

Proxmox VE project leader
Congratulations! Just upgraded from 2.3 without problems using the script.
My router kvm seems snappier, but that may just be wishful thinking ;)
I just upgraded my 2.3 as well - No complications except a package blocking the upgrade, removed the package and everything started up smooth.

Good job guys!
Be careful when using the upgrade script and read manual before run it!
./pve-upgrade-2.3-to-3.0 --purge

This command will remove the package mdadm and I have some troubles for restore LVM with pv on softRAID... It's my fault! I have not read the manual before run script. No claims to the update script
I have a trouble, after upgrade 2.3 to 3.0 my cluster from 2 computers, i have alert! /dev/disk/by-uuid/ does not exist. Somebody can help ?
Update with ./pve-upgrade-2.3-to-3.0. Same trouble on both nodes.

If you run
./pve-upgrade-2.3-to-3.0 --purge
you lost mdadm and mdadm.conf
Check it and re-install if needed
No i run it without purge.
And i'm not use raid. 3 disks in lvm.

Loving the new Proxmox 3.0. Just need the billing guys to catch up ;)

Maybe you can help me out? HostBill is waiting for more demand to upgrade their module to 3.0 compatibility. Maybe if you have both HostBill and Proxmox you could send them a quick support ticket?
I not solved trouble with hang up in initramfs, my cluster is exprerimental, not production. i just reinstall all.
I think it's happen because i added HDD to server, and expand local storage.
Just a quick question - does Proxmox 3.0 still use kernel 2.6?

I have updated two Proxmox 2.3 servers to 3.0 today and one of them uses kernel 3.2 (3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2), the other one uses 2.6 (2.6.32-20-pve).
Both work fine... but which one is the right one?
