Hello,
I had an issue with one VM which required PCIE-passthrough for NICs so I updated GRUB_CMDLINE_LINUX_DEFAULT in the file /etc/default/grub with "intel_iommu=on" then executed grub-update and rebooted the proxmox. After reboot I couldn't ping it and after deeper investigation proxmox claims that my management interface doesn't exist:

But during boot I can clearly see it:

lspci see all my network ports as well:

Any idea why it stopped working after updating my grub and how can I fix it?
