Hello! I''ve got CentOS 5.3 x64 as dom0 and the same OS for domU. I''ve installed it using the following manual: http://www.howtoforge.com/centos_5.0_xen Guest image was taken from stacklet.com Unfortunately, I can''t make domU working with public static IP. When I use bridged networking, the guest don''t have network connection at all. When I use routed networking, the guest does not even start. Virtual network works just fine, but I need to use public static IP given by ISP. Two days of google did not help at all. With best regards, Andrew _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hey Andrew. it gets a bit convoluted when there are multiple problems in the same thread. It would make much more sense if our problems were identical but these are completely different problems. Feel free to start your own thread about this since it will be easier for everyone else to understand. I hope everything works out for you. I''m running CentOS 4 and this is my /etc/xen config file: kernel="/boot/vmlinuz-2.6.26-2-xen-686" ramdisk="/boot/initrd.img-2.6.26-2-xen-686" memory=512 name="backend" root="/dev/sda1 ro" disk=["phy:vg0/backend_root,sda1,w"] extra="4" extra="clocksource=jiffies" extra="console=hvc0 xencons=tty" vif=["bridge=eth0"]> > Hello! > > I''ve got CentOS 5.3 x64 as dom0 and the same OS for domU.
