XEN을 쓰는 가상 서버 호스팅이나 클라우드 호스팅 등을 쓴다면, 일반 커널이 아니라 XEN 커널을 써야 한다. 커널을 잘못 바꾸면 운영체제가 뜨지 않아 복구하기 어렵게 되므로, 바꾼다면 종류를 잘 확인하고 신중하게 갱신해야 한다.
아래는 2014. 1. 31에 배포된 2.6.18-371.4.1.el5판 커널로 바꾸는 방법이다.
일반 커널로 판올림하기
# wget http://ftp.daum.net/centos/5.10/updates/x86_64/RPMS/kernel-2.6.18-371.4.1.el5.x86_64.rpm
# rpm -ivh kernel-2.6.18-371.4.1.el5.x86_64.rpm
# rpm -ivh kernel-2.6.18-371.4.1.el5.x86_64.rpm
XEN 커널로 판올림하기
# wget http://ftp.daum.net/centos/5.10/updates/x86_64/RPMS/kernel-xen-2.6.18-371.4.1.el5.x86_64.rpm
# rpm -ivh kernel-xen-2.6.18-371.4.1.el5.x86_64.rpm
# rpm -ivh kernel-xen-2.6.18-371.4.1.el5.x86_64.rpm
