Re: [Xen-devel] Limit I/O for individual disks of VM

[Tõnis Bramanis <tonis@xxxxxxxxxx>]

Hello

and thank You for the answer. Has anyone of You tried to limit i/o on 
the VMs?
I have about 40 containers and when the i/o gets too high, the host will 
crash with this error:
[23959.739698] sd 4:0:0:0: rejecting I/O to offline device
5       [23959.771158] Buffer I/O error on device dm-0, logical block 40259

This is not a support request! I am just referring why i would like to 
limit the disks i/o.
Regards,
Tõnis Bramanis
