The virtual infrastructure is Xen Server
If you stop / start the VM, it will stop during the running process. In case of restart (shutdown -r now), it will start. Is there a cause during kernel-related processing?
When I switched the kernel used at startup and stopped / started the server, As of March 19, 2018, it stops during booting only for the latest kernel.
NG kernel (latest): kernel-3.10.0-693.21.1.el7.x86_64 OK kernel (one before the latest): kernel-3.10.0-693.17.1.el7.x86_64
After installing the OK kernel, delete the NG kernel. Overwrite the kernel related packages with the old version.
Check kernel version
# rpm -qa | grep kernel
# uname -a
Check the kernel to be deleted and the rescue file corresponding to the kernel to be deleted (Check the file name under / boot)
# sha1sum /boot/vmlinuz-0-rescue-08564da404bc43dabf31941d25b25cb1 /boot/vmlinuz-3.10.0-693.21.1.el7.x86_64
ce98558979b4397fa8b7b59bcbd69ecd4cf38c19 /boot/vmlinuz-0-rescue-08564da404bc43dabf31941d25b25cb1

→ Since the hash value is the same, delete this rescue file later
Install OK kernel
# rpm -ivh --force http://mirror.centos.org/centos/7/updates/x86_64/Packages/kernel-3.10.0-693.17.1.el7.x86_64.rpm
Install kernel related packages (remove → install)
# rpm --oldpackage -Uvh http://mirror.centos.org/centos/7/updates/x86_64/Packages/kernel-headers-3.10.0-693.17.1.el7.x86_64.rpm
# rpm --oldpackage -Uvh http://mirror.centos.org/centos/7/updates/x86_64/Packages/kernel-tools-3.10.0-693.17.1.el7.x86_64.rpm http://mirror.centos.org/centos/7/updates/x86_64/Packages/kernel-tools-libs-3.10.0-693.17.1.el7.x86_64.rpm
※kernel-tools-libs and kernel-Trying to install tools separately
Then, I got a dependency error, so it's no good.
--------------------------------------------------------------
error:Lack of dependency:
kernel-tools-libs = 3.10.0-693.17.1.el7 is kernel-tools-3.10.0-693.17.1.el7.x86_Required for 64
--------------------------------------------------------------
Erase the NG kernel
# rpm -e kernel-3.10.0-693.21.1.el7.x86_64
Verification
# rpm -qa | grep kernel
Delete rescue file for NG kernel (Judgment by time stamp / If you don't know, you may leave it alone) ・ Vmlinuz-0-rescue-xxx → Confirmed at the beginning ・ Initramfs-0-rescue-xxx → The same time stamp as the above file
# cd /boot
# rm vmlinuz-0-rescue-f444db9ee4694d4da94a6801fda39bff initramfs-0-rescue-f444db9ee4694d4da94a6801fda39bff.img
Recreate grub config file
# grub2-mkconfig -o /boot/grub2/grub.cfg
Try stopping / starting the server
# shutdown -h now (→ then start)
# rpm -qa | grep kernel
