Enabling Wake-on-LAN on Proxmox VE server

[clawes]

I am running Proxmox at home with 6 vms to do some software and OS testing.

My server resides in the basement and runs headless.
To conserve energy I don't have this server when not in use.
Normally, I use wake-on-lan magic packet to start up this server when needed. In order to do so, I have to run the following command on the server before shutting it off for the day:

# /usr/sbin/ethtool -s eth0 wol g

Unfortunately, I get the following error message when I run this command:

"Cannot set new wake-on-lan settings: Operation not supported
not setting wol"

This command worked in the past when I had another distro running on this box. So, I suspect that might be because of the network bridging that Proxmox created during installation.
It could also be because of some ACPI configuration. I'm just no sure.

Anyway, I would like to turn of the network bridging via a script when I'm shutting down the server but not sure how to do this.

Any suggestion?

Solved!!!

The problem was due to the proxmox-ve-2.6.18 kernel. I suspect that the NIC driver needed to be updated.

I corrected the problem by upgrading to the latest version:
# apt-get install proxmox-ve-2.6.32

Then rebooted the server.

Hi
I've currently some problems to get WOL working with Proxmox VE 1.7. I think the problem lays in the configuration of proxmox, because I tested the same machine with windows 7 and there it worked perfectly. WOL is enebled all the time (even after reboot and shutdown) when checking it with "ethtool eth0" it says

Supports Wake-on: pumbg
Wake-on: g

The network card is this one

04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
Subsystem: ZOTAC International (MCO) Ltd. Device 0123
...
Kernel driver in use: r8169
Kernel modules: r8169

I think it the problem could be that the network card is shutdown when the system is halted. In order to cinfigure WOL i followed I considered this page http://www.vdr-wiki.de/wiki/index.php/Debian_-_WAKE_ON_LAN#HALT_.2F_Reboot
Does anyone have experience with enabling WOL on a Proxmox VE Server? Do I need to change anything else?

THX
