[Xen-users] Disks shared by default ?

[Sébastien Chaumat <sebastien.chaumat@xxxxxxxx>]

Hello,

 I just realized that in recent xen version (xl stack)  phy: disks are shared by default between domUs:

eg: 

disk        = [ '/dev/VGdomU/test-ext4,raw,xvda2,w' ]

can be used in multiple simultaneous domUs without a warning (learned the hard way).

When this the change from 'w!' syntax to simple 'w' for shared disk  occured ? what was the rationale for it ?

I could not find this information.

Is there any option to forbid sharing vbd accross domU by default ?

Thanks,

Sébastien
