[Xen-users] xl save/restore command

[Melanie Desaive <desaive@xxxxxx>]

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,

Melanie
