[Xen-devel] Xen Domain Restore

[Michal Novotny <minovotn@xxxxxxxxxx>]

Hi,
I have read a bug on BZ about the checkpoint file (save file) should be 
deleted after a successful Xen domain restore because it can lead to 
disk corruption. There were 3 options suggested: deleting the file, 
renaming the file to somewhat that won't be restored at dom0 startup 
(like Richard W.M. Jones suggested, renaming it to a dot-file because 
those files are not restored by xendomains script) or having an option 
in xend-config.sxp configuration file.
We may either let libvirt do it itself or we may change xend daemon. 
Anyway I think it would be better to have this option configurable in 
xend-config.sxp with option to override it via xm/virsh. Eg. you may 
have some system running on a read-only file system and all data could 
be on some another system (eg. connected via NFS).
What do you think about that? Any suggestions?

Thanks,
Michal
