[CentOS] Virtual NICs (aliases like eth0:1) won't come up after reboot

I found under CentOS 4 a few years ago that the OS would only bring up  
virtual interfaces starting with 0:0 and increasing sequentially -- if  
there was a gap, it would stop at that gap point.

	Good: eth0, eth0:0, eth0:1, eth0:2...
	Bad: eth0, eth0:0, eth0:2  (system would only start 0 and 0:0)
	Bad: eth0, eth0:1, eth0:2  (system would only start 0)

This last case looks like yours --in your config, after eth0, you  
started with eth0:1.
