DESCRIPTION:The bhyve hypervisor recently gained the ability to add or remo
 ve emulated PCI devices to a running virtual machine [1].\nThis talk will 
 showcase the key design and implementation details that went into adding s
 upport for ACPI-based hotplugging to the bhyve(8) hypervisor.\n\nWe'll sta
 rt with a deep dive into bhyve(8)'s device emulation model and the related
  parts of the virtual machine initialization process. Using this overview\
 , we will analyze the limitations of bhyve's current device emulation mode
 l and explore the key architectural changes that were required to enable r
 untime PCI device hotplugging.\nWe will then explore the newly implemented
  PCI hotplugging mechanism\, starting with a bird's-eye view of the intera
 ctions between the hypervisor and the guest and continuing with each compo
 nent of the mechanism\, diving into key implementation details along the w
 ay.\nThe talk will also include a demo of bhyve(8)'s new PCI hotplugging c
 apabilities and the overall workflow for adding or removing PCI devices fr
 om a virtual machine. We will end with an overview of upcoming work for CP
 U and memory hotplugging.\n\n[1] https://lists.freebsd.org/archives/freebs
