[Xen-users] pushing updates across lv-based domU clones

["Pallab Chakrabarty" <pchakrabarty@xxxxxxxxxxxxxxx>]

 

 

Hi All,

 

I created a centos domU based on LVM as per below cfg file.

 

The main LVM is :/dev/xen_vg/cent_os and the clone created: /dev/xen_vg/clone1

 

 

Now I want to capture the user changes on the basic volume (xen_vg/cent_os) using the clone.

 

And also incase the baseVM(xen_vg/cent_os) is updated (suppose a new software loaded & require distribution seamlessly to all such cloned domUs), the same should be reflected on the cloned domUs..

 

 

Kindly guide how to achieve this kind of pushing updates across cloned domUs and capturing real delta changes…

 

 

disk = ['phy:/dev/xen_vg/cent_os,sda3,w', 'phy:/dev/xen_vg/guest_partition_lvm_swp,sda2,w' ]

#disk = ['phy:/dev/xen_vg/clone1,sda1,w', 'phy:/dev/xen_vg/guest_partition_lvm_swp,sda2,w' ]

 

 

I could see clone1 is a full copy of the cent_os, after a custom changes are made on clone1 based domU.. how it can be configured to capture explicitly the delta part..

 

 

Thanks in advance,

 

- regards
