Summary0014310: Guest freezes with usb/pci passtrough
DescriptionGuest with usb/pci passthrough configuration freezes on startup. Logs does not contain any errors/warnings, guest type (linux, windows) is irrelevant. This behavior was seen and tested on next kernel versions:
- 3.10.0-693.11.1.el7.x86_64
- 3.10.0-693.5.2.el7.x86_64
- 3.10.0-693.2.2.el7.x86_64

The same configuration works fine on next kernel versions:
- 3.10.0-514.26.2.el7.x86_64
- 3.10.0-514.21.1.el7.x86_64
- 3.10.0-514.16.1.el7.x86_64
Steps To ReproduceConfigure guest with usb/pci passtrough and start it.

Issue seems to be fixed with kernel version 3.10.0-693.11.6.el7.x86_64, however I noticed some warnings in logs:
