Re: [Xen-users] How to stop yum update on CentOS 5.1 to modify grub

That's what I'm fearing as well. What if the Xen kernel crashes. In this

I've installed an IPMI2 module in my server. Costs about Eur 50 and
gives you remote monitors (temperature, fans) and serial port-like
console. Saved me a few trips to the DC already.
I guess I'll just exclude the normal kernel from the updates as you
suggest. P.S. Do you know if one could set a backup / fail-safe kernel
in grub, which can automatically boot if thew default kernel gives
problems?
Just set UPDATEDEFAULT to "yes" if you want the latest Xen kernel by
default and to "no" otherwise. Set DEFAULTKERNEL to "kernel-xen" and
simply leave that other kernel around.
Grub is no watchdog. So it cannot detect boot failure. If you want
something like that, arrange a budget and contact me :-)
