Virtual machine not starting

[mammutserver]

I created a virtual machine for Ubuntu on my FreeNAS server. Virtualization is enabled in the BIOS (see the settings in the picture below).
I tried different things from different forums but the virtual machine still exits with this errormessage:

[EFAULT] VM NextcloudVM failed to start: 20/09/2020 16:50:04 Listening for VNC connections on TCP port 5714 20/09/2020 16:50:04 Listening for VNC connections on TCP6 port 5714 ROM boot failed: unrestricted guest capability not available fbuf frame buffer base: 0x882e00000 [sz 16777216]

While I know your question is about running a VM in FreeNAS... If you desire to run a VM then you should seriously consider using ESXi or Proxmox. I myself like ESXi. FreeBSD is just not that mature for VMs.

With all that said, you need to provide a little more information for some help, which version of FreeNAS are you running, how much RAM do you have, what is your system configuration (hardware) and how are you setting up the VM.

Unfortunately I don't see what Nextcloud has to do with Ubuntu, my ignorance I suspect.
