Re: [Xen-users] XCP modifying cloned vms

[George Shuklin <sector-bl@xxxxxxxxx>]

Good day.

I spent some time on this problem and found three separate solution:

1) Use preseed/kickstart to create new VM by automated installation
2) Configure a 'mother' VM (wich one is cloned) with script, reading data from 
xenstore/pvargs and setting up system.
3) Detach vdi from cloned VM, attach it to 'master', perform configuration, 
reattach back to cloned VM

After few tests I decide to use 1st method, as most puristic (new ssh keys, 
clean history, access log, etc). And, with debian preseed it does not take too 
much time: about 2 minutes on gigabit link to network storage.
