Title:
PCI-passthrough instance creation problem RTX2080Ti
Status in linux package in Ubuntu:
Incomplete
Bug description:
I am running Openstack Ansible Rocky 18.1.8 on Ubuntu 18.04 nodes. I
use PCI-passthrough (IOMMU vfio) on GTX1080Tis and and RTX2080Tis. The
1080s work fine, but 2080 instances take anywhere from 3 minutes to
over 3 hours to start with qemu/KVM and the amount of time varies
randomly, with the averaging being around 1.5hrs. I tried upgrading
the kernel to 5.0.0 and it did not fix the issue. Downgrading the GPU
hosts to Ubuntu 16.04 fixed the issue, they now start in 30 seconds or
less. Sorry, but I do not have any logs. I couldn't find any errors in
any system logs including enabling debugging on libvirtd.
