KVM Guest Windows XP Network Problem

[aheissen]

Hi,
both of my KVM Windows XP Guests cannot be reached from the network.
Both Guest have no problem to access any other computer on the network.

Setup of both hosts:
virtio vmbr0

I checked the MAC and they have both different addresses.
IP of the guests is from DHCP Server on network.

please help
thanks
Andreas

What is your network setup (/etc/network/interfaces)?

 

[aheissen]

It is the default configuraton from setup:

osha001:~# cat /etc/network/interfaces
# network interface settings
auto lo
iface lo inet loopback

iface eth1 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.2
bridge_ports eth1
bridge_stp off
bridge_fd 0

Isn't the windows firewall playing tricks with you ?

You could try enabling remote desktop (which will poke a hole to port 3389, so you could telnet into it to just check if it's answering) or disable the firewall completely.

It works like a dream (i tried with xp/2003/2008) with the virtio drivers.

It is a newly configured Windows XP System and it does not answer to ping from the KVM Host.

Okay, let's rephrase my answer:

My version of xp _standard_ doesn't answer to ping (due to the windows firewall)

Done from my kvm host:
# ping 192.168.0.124
PING 192.168.0.124 (192.168.0.124) 56(84) bytes of data.
--- 192.168.0.124 ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 2999ms

However:
# arp -an
? (192.168.0.124) at 46:E1:A9:C6:C3:34 [ether] on vmbr0

It is active/working.

So no ping doesn't mean there could be something wrong with the host, it could be the guest (firewall) that is blocking.

Ymmv of course.

uhh - I am stupid - I tried it before but now I switched off the firewall and all worked fine
Thanks for pushing me in the right direction again!
