cloudstack network limitation
Hi all,
I find the network banwidth between VMs in my cloudstack server are
extremely slow while bandwidth in my environment is 1000Mbps. I want
to update some configuration to up the network speed between VMs. I
have update global settings such as network.throttling.rate and
vm.network.throttling.rate. However, it does not work! Could you
please tell me how to update network configurations about bandwidth?
ps: I use cloudstack 4.2, KVM hypervisor, advanced zone and isolated network

Thanks and Best Regards,
DuJun

Hi Kirk,
- The primary interface did end up with the network speed as per the service
offering. In my case, the service offering has a 2Gbps interface.
- The secondary interface ended up with the network offering default, which
is a 1Gbps service.
<interface type='bridge'>
<mac address='06:8b:22:00:00:57'/>
<source bridge='breth0-65'/>
<target dev='vnet2'/>
<model type='virtio'/>
<bandwidth>
<inbound average='256000' peak='256000'/>
<outbound average='256000' peak='256000'/>
</bandwidth>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
<interface type='bridge'>
<mac address='02:00:60:ea:00:04'/>
<source bridge='breth0-107'/>
<target dev='vnet3'/>
<model type='virtio'/>
<bandwidth>
<inbound average='128000' peak='128000'/>
<outbound average='128000' peak='128000'/>
</bandwidth>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</interface>
Looks to me that your docs (thanks for contributing them) is applicable for KVM too.

Re: cloudstack network limitation
Posted by Kirk Kosinski <ki...@gmail.com>.
Hi, the rate limiting functionality is complicated. It can be affected
by the type of network (shared or isolated), the direction of the
traffic, the hypervisor running the instance or virtual router, the
Network Offering for the network, the Compute Offering for the instance,
the System Offering for the virtual router, and the
(vm.)network.throttling.rate parameters in Global Settings.
So there are many places to check. It is explained in the docs:
http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Admin_Guide/network-rate.html
I wrote much of this section, but I think it might be out of date. I
didn't know support for rate limiting with KVM had been added. I think
the example at the end might be wrong for KVM, but the rest should be valid.
Best regards,
Kirk

Hi Marty,
Stop and then start VM instead reboot VM can update the value of "inbound |
outbound",
root@cloudstack-ubuntu:~# virsh dumpxml i-2-3-VM | egrep "inbound|outbound"
<inbound average='2560000' peak='2560000'/>
<outbound average='2560000' peak='2560000'/>
However, the real transportation speed is still the same, it's only about
600KB/s, which is far less than 2560000bps.
Do you have any idea?

Hi DuJun,
Can you confirm you are fully stopping the VM, the starting it as opposed
to just rebooting it?

@Nux @Marty
As you can see, I use DefaultIsolatedNetworkOfferingWithSourceNatService and
I update network rate to 20000Mbps. Meanwhile, I reboot the VMs. However,
inbound and outbound value are all the same!
root@cloudstack-ubuntu:~# virsh dumpxml i-2-3-VM | egrep "inbound|outbound"
<inbound average='25600' peak='25600'/>
<outbound average='25600' peak='25600'/>
Egress Default PolicyDenyAvailabilityRequiredCreated by systemYesSpecify
VLANNoSpecify IP rangesNoConserve modeYesNetwork Rate (Mb/s)20000 Mb/sTraffic
TypeGuest
So, I feel confused about how Cloudstack limit the network rate for guest
VMs.

I assume you are stopping and relaunching the VM.

As I said initially this may be bound to the network offering. Eg

Hi Marty,
My problem is that even though I have update global settings about network
rate, but inbound and outbound are not affected. Look like that:
root@cloudstack-ubuntu:~# virsh dumpxml i-2-3-VM | egrep "inbound|outbound"
<inbound average='25600' peak='25600'/>
<outbound average='25600' peak='25600'/>
No matter what I set for network rate in global settings, inbound and
outbound for VM are always the same!

Hi Du Jun,
You can find my thread here
http://mail-archives.apache.org/mod_mbox/cloudstack-users/201310.mbox/thread?5,
I was having the exact same issue.
My conclusion "It appears upgrading (Linux) VM kernels to 3.5 fixed the
Inbound traffic issue. Drivers for e1000 on Windows are (apparently)
provided by Microsoft but are the latest version. I have a feeling this
issue was brought in a few KVM releases ago."
To use Windows VMs I would recommend changing their OS Type in Cloudstack
to, 'Other PV'. 'Windows PV' may also work but I have not tested it.

You will need to adjust the following settings:
network.throttling.rate
vm.network.throttling.rate

I think there is a network limit imposed of 200 Mbps in the network
offering, check it out. This limit is enforced via `tc`, see the man
page to learn how to show current limitations.

Hi Marty,
Thanks! I am the root of my Cloudstack cluster. BTW, could you please
tell me the "key words" of your previous question? Maybe I can search
it using Google.

Hi,
What type of guests are you experiencing this with?
There should be a mail archive (on mailmark?) where I raise and resolve the
issue.
Unfortunately I can't find it ATM, but will send you a link later on if I
get a chance.
Good luck!
