Hi,
On an Ubuntu 16.10 host I'm running a Linux Mint 18.1 guest, passing
through a Quadro FX4800. The guest is using the official Nvidia drivers.
I can run the Mint guest once. If I try starting it again, it pegs the
CPU and that's it. However, if I then start a Windows instance with that
card, it starts fine, I stop it, and then I can run the Mint guest
again. But just once. (In that case I notice that the screen comes up
immediately on the Linux guest and I can see the entire boot process,
which is unusual for my configuration .)
Unsuccessful fixes: echo "1" > /sys/bus/pci/devices/0000:02:00.0/reset.
I extracted the card's ROM and put it in a "<rom file='...'/>" tag.
Turning the ROM BAR off.
So it sounds like maybe the FX4800 isn't resetting properly after the
Linux guest has used it, but since Windows doesn't have that issue,
perhaps it's something else.
Any ideas would be appreciated. My config file follows. Thanks,
Steve
