Proper way of disabling IPv6 subsytem in RedHat Linux 6 / CentOS 6 (dont unload modules or so)
in /etc/sysctl.conf : net.ipv6.conf.all.disable_ipv6 = 1
in /etc/sysconfig/network : NETWORKING_IPV6=no
in /etc/sysconfig/network-scripts/ifcfg-eth0 : IPV6INIT=”no”
disable iptables6 – chkconfig –level 345 ip6tables off
reboot
done 😉
PS: if you have more eth interfaces, use brain 😉

I have thick provisioned server, and I need move it and shrink it. As Thick option provides flat file of full size , even if OS is few GB, I have full size vmdk file ;( which is harder to copy around. Thin provisioned vmdk disk is possible shrink via ESX shell command ( vmkfstools –punchzero *.vmdk) but what to do if disk is in Thick state ? Its possible, but little bit more complicated.
