[Xen-devel] Another migration question

[Stefan Berger <stefanb@xxxxxxxxxx>]

Hi!

  I had a look at the migration code in the kernel 
(arch/xen/kernel/reboot:__do_suspend()). I am surprised that migration 
actually seems possible when the block device frontend has mounted a 
device. Shouldn't it rather refuse to be suspended, assuming that the 
partition can be migrated to another machine and possibly harm a 
filesystem there? I would also think that there should be a user-level 
daemon trying to unmount hard drive partitons before any migration is 
initited. I suppose the same problem will arise with the USB driver.

Regards,
    Stefan Berger
