# Instance Creation Failure

Instance creation can fail in a Linux / KVM environment if the Image Library host is configured using DHCP, and the IP address changes when the lease is renewed.

## Updating IP address of Glance Image Library endpoint in KVM environment

If you are using KVM as your hypervisor, wait for 30-60 seconds after a restart of the Image Library host.

Once the connection with the control plane has been reestablished, follow the steps given below.

1\. Navigate to Infrastructure>Hosts.
