Hello everybody,

I am currently trying to figure out, what the xl commands "save/restore" are exactly doing in case I leave the domain running after issuing the save command.

I tested the following szenario:


Saving domain with "xl save -c <domain> <statefile>"

After completion creating a new file on domU.

Destroying domU

Restore domU with "xl restore <statefile>" -> The new file disappeared from domU.

Shutdown domU

Recreate domU from configfile with "xl create <configfile> -> The file is back again.


Does the save command checkpoint the domUs filesystems so that it can be used to create kind of a snapshot?

Can someone point me to some in depth documentation or maybe give a short summary, what the command is actually doing?

Many thanks in advance.

Kind regards,
