Hi,
Thanks for the suggestion. I'm not necessarily saying this patch itself has an
issue, just that it is the point in the git history at which this slow boot
time issue manifests for us. This may be because the patch does actually fix
the other issue I described above related to BAR assignment not working
correctly in versions before that patch, despite boot being faster back then.
(in those earlier versions, the PCI devices for the GPUs were passed through,
but the BAR assignment was erroneous, so we couldn't actually use them - the
Nvidia GPU driver would just throw errors.)
After I initially posted here, we also discovered another kernel issue that was
contributing to the boot times for this config exceeding 5 minutes - so with
that isolated, I can say that my config only takes about a 5 minutes for a full
boot: 1-2 minutes for `virsh start` (which scales with guest memory
allocation), and about 2-3 minutes of time spent on PCIe initialization / BAR
assignment for 2 to 4 GPUs (attached). This was still the case when I tried
with my GPUs attached in the way you suggested. I'll attach the xml config for
that and for my original VM in case I may have configured something incorrectly
there.
With that said, I have a more basic question - do you expect that it should
take upwards of 30 seconds after `virsh start` completes before I see any
output in `virsh console`, or that PCI devices' memory window assignments in
the VM should take 45-90 seconds per passed-through GPU? (given that when the
same kernel on the host initializes these devices, it doesn't take nearly this
long?)
I'm going to attempt to profile ovmf next to see what part of the code path is
taking up the most time, but if you already have an idea of what that might be
(and whether it is actually a bug or expected to take that long), that insight
would be appreciated.
Thanks,
Mitchell Augustin
