[Qemu-discuss] How to use IO throttling and IO burst

[Alexandre LAURENT]

Hi,

I am using QEMU 1.7.1 and I would like to know how to use the 'drive' options :

- bps_wr

- bps_wr_max

- bps_rd

- bps_rd_max

Can you explain me how to limit IO access between two VMs, where one would be limited and the second one have full IO access. My point is to give full IO access to the limited one when the second is doing nothing.

Thanks for your help,

Best regards,

Alexandre
