    What's in the Xen configuration file of that vm?

    The configuration file :
    kernel = '/boot/vmlinuz-2.6.27-11-server'
    ramdisk = '/boot/initrd.img-2.6.27-11-server'
    memory = '256'
    root = '/dev/xvda2 ro'
    disk = [
    'file:/home/xen/domains/xen3.example.com/swap.img,xvda1,w',
    'file:/home/xen/domains/xen3.example.com/disk.img,xvda2,w',
    ]
    vif = [ 'ip=87.255.77.58,mac=00:16:3E:6E:64:89,bridge=eth1' ]


    name = 'xen3.example.com'
    console='hvc0'
    on_poweroff = 'destroy'
    on_reboot = 'restart'
    on_crash = 'restart'


    root@xen3:~# dmesg | grep eth

    Can you try
    Code:
    vif = [ 'ip=87.255.77.58,mac=00:16:3E:6E:64:89' ]
    instead of
    Code:
    vif = [ 'ip=87.255.77.58,mac=00:16:3E:6E:64:89,bridge=eth1 ' ]
    ?

    What's in /etc/xen/xend-config.sxp?

    Thank you for helping

    Thank you
    ufw firewall blocks network connections from xen virtual mashine.
    If I disconnect it Internet works on xen:)
