These changes to the grub.conf should enable your serial console to work correctly. You

should be able to use any number for the ttyS and it should work like ttyS0 .

16. Network Bridge Errors

Red Hat Virtualization can configure multiple Virtualization network bridges to use with multiple

ethernet cards. To successfully configure multiple network bridges for ethernet cards, you must

configure the second network interface by either using the system-config-network TUI/GUI, or

by creating a new configuration file in /etc/sysconfig/network-scripts . You should use a

process to setup multiple Xen bridges. This is an example config file for a second NIC called

'eth1' :

#/etc/sysconfig/network-scripts/fcfg-eth1

DEVICE=eth1

BOOTPROTO=static

ONBOOT=yes

USERCTL=no

IPV6INIT=no

PEERDNS=yes

TYPE=Ethernet

NETMASK=255.255.255.0

IPADDR=10.1.1.1

GATEWAY=10.1.1.254

ARP=yes

Copy the /etc/xen/scripts/network-bridge to /etc/xen/scripts/network-bridge.xen .

Edit /etc/xen/xend-config.sxp and add a line to your new network bridge script (this

example uses "network-virtualization-multi-bridge" ).

In the xend-config.sxp file, the new line should reflect your new script:
