Issues with Shaping in VMmanager
 

I have a VMmanager, and a VDS with QcoW file system. The set incoming/outgoing parameter for VDS setting is 97657.

In reality, I get 300 kilobytes/s (approximately 2-3 megabits). If the set parameter is removed, then I get around a gigabit.

Given that I have not changed any tamplates or other settings, why is the Shaper not functioning correctly? What can I do to fix this issue?

Hi MikeB,

For limiting data transfer speed for virtual machines Vmmanager uses libvirt. VMmanager set parameters to vds's xml file.

Please show us a result of command execution

virsh dumpxml billmgr |egrep "inbound"

Also please show us libvirt version.

<bandwidth>
<inbound average='97657'/>
<outbound average='97657'/>
</bandwidth>

libvirt version: 0.10.2

There is problem in this libvirt version. The newest version 1.2.3 works properly with tc.
So, you can update libvirt manually.

Also, we are thinking about put 1.2.3 version into our own repository and use only this version of libvirt for VMmanager.
