### xclmgmt driver issues
If the following error is displayed when running [xbutil validate](https://xilinx.github.io/XRT/master/html/xbutil.html#xbutil-validate), it suggests the management driver is not working correctly.
```

- See if the machine is running a [supported hypervisor](common-steps.html#host-machine-and-hypervisor-information)
- Check to see if the drivers are present with
- `lsmod | grep xclmgmt`
- `lsmod | grep xocl`
- [Unload/reload XRT drivers](common-steps.html#unload-reload-xrt-drivers)
- See if a similar issue is posted on [Xilinx forums](https://support.xilinx.com/s/topic/0TO2E000000YKXlWAO/alveo-accelerator-cards)

### Failed to find xclbin
If the following message is displayed when running [xbutil validate](https://xilinx.github.io/XRT/master/html/xbutil.html#xbutil-validate) it suggests there is an issue with the installed deployment package.
```
Test 3 [0000:03:00.1] : Verify kernel
Test 4 [0000:03:00.1] : iops
Test 5 [0000:03:00.1] : Bandwidth kernel
Test 6 [0000:03:00.1] : vcu
Validation completed, but with warnings. Please run the command '--verbose' option for more details
```
Rerun validate adding the `--verbose` switch and look for output including the following
```
Test 6 [0000:03:00.1] : iops
Description : Run scheduler performance measure test
Details : verify.xclbin not available. Skipping validation
Verify xclbin not available or shell partition is not
programmed. Skipping validation.
Test Status : [SKIPPED]
-------------------------------------------------------------------------------
Test 7 [0000:03:00.1] : Bandwidth kernel
Description : Run 'bandwidth kernel' and check the throughput
Details : bandwidth.xclbin not available. Skipping validation
Verify xclbin not available or shell partition is not
programmed. Skipping validation.

```
If either xclbin is not available, follow next steps below.
Next steps:
- [Determine packages installed on the system](common-steps.html#determine-xrt-packages-using-the-package-manager)
- Follow package install steps in [Modifying existing XRT or platform install](modifying-xrt-platform.md)

### xbmgmt commands not working
If `xbmgmt` commands are not working and there are no errors displayed, it may indicate an error with the XRT installation package.
