Re: Making Copy of KVM VM

Hi gpma,

if the VM ist stopped (not running) using cp is a simple way. BUT to make a copy of the xml file. it's better to use

Code: Select all

virsh-dumpxml [VMName] > [VMName].xml
, because if you change the KVM-Environment or the Domain - you need a DUMP-File!

Re: BIND DNS udp_bad_chksum
