I've just setup a windows 2008 guest, it works very fast, but I had problems with networking, Windows 2008 detects network cards and network connection (pluged), but never get IP by dhcp, I set a static IP but no network connection is possible (Unidentified network).

Other guests openvz works perfect on same hardware.

I tried with e1000, rtl8139 and virtio, all the same.

My Proxmox version is:
PVE01:~# pveversion -v
pve-manager: 1.6-2 (pve-manager/1.6/5087)

is your Proxmox VE in a datacenter? other KVM guests are working?
 
Thanks for your answer:

My Promox VE is located on my local network, and is a 2 server cluster based on HP DL360G6. I've installed a Ubuntu 10.04 KVM and had the same problem.

Hi afugone,

I already had a similar problem with win 2003 R2. Device manager shows e1000 working, but in fact it is not. Tom suggested to install the latest driver from Intel site. See :
http://forum.proxmox.com/threads/41...R2-an-d-kernel-2.6.32-2-pve?p=24209#post24209

You can find the driver there :
http://downloadcenter.intel.com/Sea...uctProduct=Intel®+PRO/1000+MT+Desktop+Adapter

Which virtio driver do you use for Windows 2008 ? If it is 2008 R2, you need a signed virtio driver, which is available via RHEL (or perhaps Fedora ?).

Hopes this helps...

Alain
 
I assume an issue is in the network config inside your guests?

also post the output of 'pveversion -v'
 
I'm sorry for my delay to answer, I was out for some days, here is the pveversion, is the same I sent at the begning, by the way where can I dowload a signed virtio driver, I'm using win 2003 R2. So is better use virtio or e1000?

Thanks for your comments
Regards
Alfredo
