Vboxmanage bandwidthctl disk does not work for Windows Linux

[RohitJ]

Hi,

I have tried running as per the advice in the manual:

VBoxManage bandwidthctl "VM name" add Limit --type disk --limit 20M
VBoxManage storageattach "VM name" --storagectl "SATA" --port 0 --device 0 --type hdd
--medium disk1.vdi --bandwidthgroup Limit
VBoxManage storageattach "VM name" --storagectl "SATA" --port 1 --device 0 --type hdd
--medium disk2.vdi --bandwidthgroup Limit

However, when I run fio benchmark to check I am always getting a bandwidth which is not related to the limit I set.

So, I ran the fio benchmark with ioengine=posixaio to make sure that the io is asynchronous, however I see no difference.

This runs fine on a MAC and there are issues with Windows, Ubuntu and RHEL6.

Please advise!

This should probably be reported to bugtracker if you want to get it fixed.
