Create and revert snapshots

[abhisheksha]

Hi,

How can I create a snapshot of a VM and revert it? This is not for simple Routers and switches wherein the config can be exported to a txt file. I'm asking for VMs like Cisco FMC or ISE or NGIPS. Thanks!

fmc itself has export xml file.
ISE has backup too.
Snapshots fir such nodes will fill up your eve hdd very soon...
Qemu nodes like FMC or ISE can be 30Gb large, as lab HDD
If such feature will come make lab clone with all saved HDDs, it will be in EVE pro only.

I imagine what do you mean. Like SEC lab prestage and use it as preconfigured rack every time.
Well it is possible now, but you have to create such rack with all initial configs. Then properly shutdown nodes FMC, ISE, Windows... Soft suchdown from cli..

Then make full clone of this lab.

/opt/unetlab/wrappers/eve_wrapper -a clone -T 10 -O 10 -F /opt/unetlab/labs/CFG\ test.unl

Dont forget change POD numbers

T Source POD
O Destination POD

It is recommended if your lab name does not contain spaces, like "secv5_lab_rack is fine.unl"

If space space in lab name is used, add \ after the word with space

Example of lab name:
sec clone script.unl = sec\ clone\ script.unl

/opt/unetlab/wrappers/eve_wrapper -a clone -T 10 -O 10 -F /opt/unetlab/labs/sec\ clone\ script.unl

NOTE: Cloned lab size will be same as original one !!! Make sure your EVE HDD have space !
