Question

Como posso atualizar o kernel no Centos sem reiniciar?

Answer 1

De man kexec :

kexec is a system call that enables you to load and boot into another kernel from the currently running kernel. kexec performs the function of the boot loader from within the kernel. The primary difference between a standard system boot and a kexec boot is that the hardware initialization normally performed by the BIOS or firmware (depending on architecture) is not performed during a kexec boot. This has the effect of reducing the time required for a reboot.

Para instalá-lo: yum install kexec-tools

Com o KSplice não suportando o seu SO, você está sem sorte.
