[one-users] Cgroup blkio with Opennebula

[Ruben S. Montero]

Hi,

If you need to test the blkio you can add something like this:

RAW = [
      TYPE  = "kvm",
      DATA  = "<blkiotune><weight>100</weight></blkiotune>"
]

to the VM templates.


Just in case you missed it, OpenNebula generates <cputune><shares> for cpu
cgroups.This value is based on the CPU template attribute so a VM with
CPU=1 will received twice the shares of other VM with CPU=0.5. More info
here [1].

We may think to add an specific template attribute for the blkio cgroups
driver...

Please keep us updated with the results of your tests.

Cheers

Ruben
