Hi all In commit a52a4c471703e995ceb06f6157d70747823e8a0d said:
The VFIO configuration space stays untouched, so the guest OS may choose to skip restoring the BAR addresses as they would seem intact. The PCI device may be left non-operational. While the guest OS choose to restore the BAR addresses only when pci device no_soft_reset is not set. So we may not reset the BAR address when no_soft_reset is set. Thanks. Louis
