KVM Cobbler Unattended Batch installation operating system

2016-12-10

Initial configuration address: Http://www.cnblogs.com/shenzhonglin/p/6126466.html Cobbler: A tool for automated network installation systems that integrates PEX, DHCP, DNS, TFTPD, sync, and other services. Can be for everyone to manage the installation of operating system Kvm:linux system with the virtualization software, self-search for information learning.

Create a virtual host: Copy MAC address to cobbler Create cobbler system run to implement unattended installation Some small pits:1, DHCP: Obtain an address, configure DHCP correctly, and determine the DHCP service startup. DHCP is Cobbler sync before it starts. 2, the installation system cannot find the Kickstarts file, when creating the profile, make sure the file name is correct3, Xamnage boot installation prompt SDA problem. When created, hard disk resources are not too small. OPS knows the default allocation system disk resource space
