[Xen-users] Can't ping gateway (SOLVED !!!!)

["Jk ." <jankarlitos@xxxxxxxxxxx>]

HI again,

This is the solution to my problem, hope it helps someone in the future.

First of all, thanks to Ramachandran Radhakrishnan for helping me with this.

The problem was my NIC: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)

What happens, is that the NIC's driver sets the HWADRRESS = FE:FF:FF:FF:FF:FF, and that's the same address used in xenbr0

What you need to do, is set the address manually. in Centos you can do this by setting /etc/sysconfig/network-scripts/ifcfg-eth0

you need to set MACADDR=00:00:de:50:f1:45 (just an example)

be sure you set MACADDR and not HWADDR




and that's it !!!!  thanks, to everyone... now i can continue my virtualization process...
