Ilari Mäkelä wrote: Hi!I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I'm using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I'm using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it's own. So basicly both of my virtual servers use a network card (physical one) of their own. The problem is that I can't get ssh or ping to work between my dom0 and domU's. I can get ssh connection to and from my other linux server using dom0 or one of my domU's and connection to internet works also. Here are my domU config files:inno:/home/iler# cat /etc/xen/i28 kernel = "/boot/vmlinuz-2.6.18-6-xen-amd64" ramdisk = "/boot/initrd.img-2.6.18-6-xen-amd64" memory = 512 name = "i28" vif = [

Hi, I think you might want to check this: Here is ifconfig from dom0: eth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3422 errors:0 dropped:0 overruns:0 frame:0 TX packets:2133 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:347388 (339.2 KiB) TX bytes:417210 (407.4 KiB) Interrupt:16 Base address:0x6000 Especially the hardware address.
