5.1 passthrough slow boot

tl5k5 · May 4, 2018

Can anyone look at my config below and tell me why my FreeNAS VM is very slow to POST when it starts?
This old thread talks about kernel bugs, but it's surely fixed by now: https://forum.proxmox.com/threads/proxmox-4-0-pci-passthrough-broken-in-several-ways.24178/

Thanks!
