iMovie event library on a network drive, NAS

I was shocked to find that iMovie '09 would not allow storing event libraries on networked disks. The AFP volume would show up, but remain non-functional with a yellow exclamation sign.

Proxmox PCIe passthrough on HP gen8 - failed to set iommu for container

Problem Setting up PCIe passthrough from host to a VM was supposed to be easy. However, being an HP server, there was a bit more to it than usual.

Luckily, HP had issued a customer advisory on this. It describes a convoluted method to disable this RMRR per slot basis. It seems to work for me, so I thought I'd write down some notes if I ever run into this again. Basic setup Proxmox has decent instructions for preparing the host for passthrough setup in general, in summary: -  add  intel_iommu=on to   GRUB_CMDLINE_LINUX_DEFAULT  in the file  /etc/default/grub - add vfio modules to  /etc/modules
