Re: [Xen-users] Dom0 issue



You're missing the point.

What did you mean by "if socket 0 starts malfunctioning"? The CPU got
overheat and dead?

If a CPU is dead, then an x86 server is dead. That's it. There's no
difference whether it's xen or not, or whether you use cpu pin or not.

Unless you have another definition of "malfunctioning"?
