pls try with latest kernel (from pvetest repo, based on RHEL64, pve-kernel-2.6.32-22-pve: 2.6.32-107)
Thanks Tom, it's all working now, a BIG thanks to the Proxmox team
Problem: I had Proxmox stable V3 running nicely on a Intel i5 quadcore. The motherboard USB subsystem died so I upgraded to a new mobo: Intel DZ87KLT.75K and CPU: Intel Core i7 4770K (quad core with quad threading), Haswell. socket 1150.
Proxmox refused to start with the following error at bootup: "unsupported cpu family 6 model 60"
What I did:-
1) moved the boot drive to a spare i5 machine and booted it.
2) Changed /etc/udev/rules.d/70-persistent-net.rules to suit the new machines network cards
3) Edited /etc/apt/sources.list as below
deb
http://ftp.au.debian.org/debian wheezy main contrib
# PVE packages provided by proxmox.com
# deb
http://download.proxmox.com/debian wheezy pve
# PVE packages provided by proxmox.com
deb
http://download.proxmox.com/debian wheezy pvetest
# security updates
deb
http://security.debian.org/ wheezy/updates main contrib
4) Ran 'apt-get update"
5) Ran apt-get upgrade
6) Rebooted, Proxmox ran
7) Moved boot drive to machine with the new Haswell cpu and booted
8) Deleted everything in /etc/udev/rules.d/70-persistent-net.rules
9) Rebooted
10) Proxmox ran fine, network worked fine as Udev had redone /etc/udev/rules.d/70-persistent-net.rules to suit the new motherboard
11) Started a VM that was installed and running before I had the new CPU problem, and it's working perfectly
