1. log in into each dom-U and run
#yum update -y
this will update kernel devel and kernel headers on dom-U
failing to do this will make iptables not able to start
2. fix xen kernel script
this will update latest kernel on dom-U (do this on every dom-U before rebooting them!!)
# /script/fixxenkernel
3. xm list
this will list all dom-U
4. xm reboot
this will reboot dom-U server. or just reboot entire system.
if you have iptables problem after dom-U reboot please install kernel-headers
#yum -y install kernel-devel kernel-headers
iptables: Table does not exist (do you need to insmod?)
then,
#modprobe ip_tables
hope this will save some time to figure up why iptables not working.
remember: i'm using hypervm. fixxenkernel scripts only available on hypervm
