This issue didn't happen in my last test with host kernel 6.1.0-rc4,kvm commit 549a715b and qemu commit c15dc499. Reproducing Steps: Try to create 2 VFs echo 2 > /sys/bus/pci/devices/0000:98:00.0/sriov_numvfs Actual Result: Error log: No such file:/sys/bus/pci/devices/0000:98:00.0/sriov_numvfs Expected Result: 2 VFs successfully created -- You may reply to this email to add a comment.
