Fixpermissions command fails with permission denied on EVE-NG VM

Post by akehan » Thu Dec 25, 2025 1:32 am

Hi everyone,

I’m running EVE-NG Community Edition on VMware Workstation, and I’m having an issue with the fixpermissions command. After uploading new images (Cisco IOSv and IOU), the nodes fail to start, so I tried running:

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions


However, I keep getting a permission denied error, even when logged in as root. I verified that I’m using the correct credentials and that the filesystem is not mounted as read-only. The VM otherwise seems to be running fine, and disk space is sufficient.

Has anyone experienced this before? Is there something specific I should check (filesystem, ownership, or VM configuration) before running fixpermissions? Any help would be appreciated.

Thanks in advance!

You need to enable virtualization in bios and VM, check with kvm-ok command if it's enabled or not.
