You must first install some services in Yum and then install them in RPM.

yum -y install dracut linux-firmware xfsprogs kmod kexec-tools rpm -ivh kernel-3.10.0-693.el7.centos.toa.x86_64.rpm

After the restart, run uname-R to view the version.3.10.0-327.el7.x86_64Changed3.10.0-693.el7.centos.toa.x86_64

Runlsmod | grep toaCheck whether the Toa module is loaded. If it is not loaded, you can usemodprobe toaCommand to enable.

[[email protected] ~]# lsmod | grep toatoa                    12745  0 [[email protected] ~]# 

The Toa module can be automatically loaded upon startup.

Succeeded
Note: The above command is successfully tested only on the vmvm, and fails on both hyper-V and the physical machine. hyper-V is lost after the compilation is successful, the physical machine cannot start centos6.5.

April August 29, 2018: after testing, in hyper-V, the centos6.x system encountered the problem of NIC loss after kernel compilation.
