Cause

This issue is caused by the communication issue between glance-api and ESXi vmkernel port because NFC communication is used for downloading a glance image.

For example, if MTU of vmkernel port is set to "9,000", glance-api and vmkernel port tries to use "MSS=8960" for TCP communition. However, MTU configurations of Openstack controller nodes are "1,500" by default. As a result, packet with larger size than 1500 are dropped at vNIC of an Openstack controller node running glance-api.

Resolution

This issue can be fixed by troubleshooting network issues.
For example, this issue can be fixed by matching MTU among vmkernel port and Openstack contoller nodes.
