network bandwidth issue
Hi all
ACS 4.17.2
Hypervisor KVM
We are seeing strange behaviour on the network bandwidth within guest VM's
VMs are able to send at full speed - 1Gb/s but are only receiving at 200Mbits/s - can anyone shed any light on this behaviour?
BR

Thanks Jordan
I figured it out in the end.
I set the "vm.network.throttling.rate" and the "network.throttling.rate" global settings both to 1000mb\s and restarted the mgmt. service.
The issue was we had to stop any VM's that had a compute offering with NULL value on the network rate and start them again to pick up the new setting - just restarting the VM's doesn't work.
After doing this the VM's are now receiving at 1Gb\s as well as sending at 1Gb\s

Hey Gary,
One thing that comes to my mind is that the default Network offering limit is 200 MBps.
You can check it from the GUI in the Network Offerings section.
Best regards,

Hey Gary,
One thing that comes to my mind is that the default Network offering limit
is 200 MBps.
You can check it from the GUI in the Network Offerings section.
Best regards,
