Question
When performing verification job, only network verification fails and the verification report shows that access to the host's internal system is possible.
Answer
Issue Description
There are several reasons why the verification job only fails during the network verification phase:
- Restricted by verified virtual machine resources
- Restricted by verification duration
Resolution
Restricted by verified virtual machine resources
- For verification hosts with larger source (CPU, memory, etc.) machines, we recommend using the same size (CPU, memory, etc.)configuration as the source machine for verification testing. You can configure it during verification job configuration. The following is for your reference.

Restricted by verification duration
The pass rate of verification job can be improved by extending the Verification Time and appropriately reducing the Startup Detection Time.

- Startup Detection Time: how many packets need to be pinged before network verification is successful, one packet per second.
- Verification Time: the running time of the verification job. If the network verification fails within this time, an error will be reported and the job will exit.
