Information

EID is the Environment ID used by the PVA Agent to identify a container or a virtual machine. This EID must be unique for all containers and virtual machines in a Parallels Virtual Automation (PVA) managed infrastructure.

This article describes how to regenerate the EID for a container.

Resolution

On Linux:

Find the container EID:
```
~# cat /vz/private/CTID/.vza/eid.conf
```

Remove the EID cache file:

~# rm /var/opt/pva/agent/etc/configs/EID

Use the uuidgen utility to obtain a unique EID:
```
~# uuidgen | tee /vz/private/CTID/.vza/eid.conf
5187b2c8-a3a1-42f6-8d23-343effde0d10
```
NOTE: Replace CTID with the actual container ID.
Restart the PVA Agent to apply these changes:
```
~# pvaagent restart
```

On Windows

Find the container EID:
```
type C:\vz\private\CTID\.vza\eid.conf
```

Remove the EID cache file:

del C:\vz\PVA\Agent\Data\etc\configs\EID

Stop the PVA Agent:
```
sc stop pvaagent
```
Use the newvpsid utility to obtain a unique EID:
```
newvpsid > C:\vz\private\CTID\.vza\eid.conf
```
NOTE: Replace CTID with the actual container ID.
Start PVA Agent
```
sc start pvaagent
```
