https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251046 Anatoli <me@anatoli.ws> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |me@anatoli.ws --- Comment #7 from Anatoli <me@anatoli.ws> --- Hi All, > Even then I'm not sure why it's useful to jail the bhyve process - what d= oes it buy you? The idea to run bhyve inside jail is to provide an additional layer of secu= rity for potential vm-escape vulnerabilities in bhyve. This is the way VMs are executed on Linux (protected by AppArmor and SEL) a= nd Illumos. Currently it's possible to run bhyve in jail, but not with PCI passthrough. > A better solution would be to extend pci(4) so that bhyve can use it to d= o everything required for PCI passthrough. Mark, could you please give us a hint on what should be done to extend pci(= 4) so jail changes are not needed? We are willing to implement this, but need = some guidance. One more security improvement that bhyve needs is to run it without root, b= ut that's another story for another report. --=20 You are receiving this mail because: You are the assignee for the bug.=
