Zir,
Thanks for the response. I really thought that would work, as the problem does
seem to follow the chipset but alas no change. I added intremap=off per your
suggestion and found the nox2apic, which I presume will enable xAPIC instead.
I searched for information about setting a bit to do
The Nehalem era X58, 5500 and 5520 Chipsets had a notoriously broken Interrupt

Thanks for the reply.
There is no problem with USB on the host or guest when this happens, nor are
there any errors on the console or in the logs. One of the first things I did
was test without USB passthrough, and there was no difference. Furthermore,
I've tested many kernels outside of
Oh I saw your other thread but didn't see this one where you show usb
passthrough... I've seen usb passthrough fail with an i7 5820K and X99
chipset on some kernels between 4.9 and 4.13 (but 4.13.11 works fine).
... 4.10 is in that range, but I didn't test that one on the X99. And I
don't have
To put it another way, running concurrent VMs when at least one VM has an
assigned GPU will always result in a GPU driver crash, unless all VMs and all
their attached media reside on the root disk. I've been able to replicate this
consistently across three motherboards, all with the X58
