The bug that you refer to does not appear to be related to your issue. What does "pciconf -l" print in your FreeBSD VM? ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe,

Re: bhyve clock problem, solved by kern.timecounter.hardware=TSC-low in /etc/sysctl.conf

2015-04-10 Thread Ryan Stone
Using the TSC as the default timecounter in a VM is dangerous. On some hardware, the TSC is not synchronized across all CPU cores. This means that if a VM migrates from one core to another, it could see the timecounter value go backwards. Time jumping backwards can cause all kinds of hilarity.

HEADS UP: PCI SR-IOV infrastructure has been committed to head

2015-02-28 Thread Ryan Stone
I've just finished committing support for PCI Single Root I/O Virtualization in the pci subsystem to head. This should be a no-op for everyone right now, but there were some minor refactorings in the pci code that could have a lingering bug. I did make sure to test that it boots on a variety of

Would there be interest in virtualization of the ixgbe driver?

2011-01-04 Thread Ryan Stone
At $WORK I've implemented an extension of the ixgbe driver that provides multiple virtualized ixgbe interfaces. The implementation uses the 8259[89]'s virtualization features, so the rx and tx paths of the virtual interfaces are completely independent. From the perspective of everything above
