[Bug 229824] Fatal trap 1 when resuming from S3 with a VirtualBox VM running
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229824 John Baldwin changed: What|Removed |Added CC||j...@freebsd.org --- Comment #1 from John Baldwin --- FreeBSD doesn't have a way to let external hypervisors like vbox work across suspend and resume. I did add a hook for bhyve in https://svnweb.freebsd.org/base?view=revision=259782. We would need something similar. The same issue matters for permitting multiple hypervisors being active at the same time (e.g. you can't run both bhyve and vbox at the same time currently). I had been thinking of adding a kind of hypervisor framework to let hypervisors allocate the VMX region and then permit associating it with a given process so that you could do the right vmxon/vmxoff during context switch. Having that would also allow us to more cleanly handle suspend/resume for arbitrary hypervisors. One thing you might be able to do for now is change the vbox driver to set the same vmm_resume_p pointer that bhyve's vmm.ko sets during MOD_LOAD to a function that reinvokes vmxon with the right address on each CPU during resume. Probably both bhyve and vbox should also fail to load in MOD_LOAD if that pointer is already non-NULL which would enforce only one could be used at a time. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

You have to use MSI interrupts for pass-through devices for bhyve. Those errors look as if the guests are trying to use legacy INTx interrupts. -- John Baldwin ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
