An administrator cables all interfaces on a newly added AHV host and starts migrating VMs to it. Users report that network connections are much slower to the VMs after the migration. What is a possible reason for this issue?
A.
The host still has the default bond configuration
B.
The VMs do not use the same interfaces as the CVM
C.
The network is slower because the host is farther away
D.
The CVM on the node has not fully joined the cluster
Should be A
default bond is active-backup which is the slowest.
Chances are the other hosts are configured to use both 10G ports hence why users are seeing faster speeds when connecting to their vm's.
The correct answer is D, until data resiliency is completed on the CVM (new host CVM), traffic will be passing over the network and not pulling from local disks , yes the default bond is active backup, but in order to saturate a 10GB uplink you would need a crazy amount of traffic so changing to balance tcp, or slb is just increasing the pipe bandwidth, local data will be 20GB pipe any day.
