I tried ./configure --disable-system --enable-virtfs and make. But didnt
face any build failure. Could you please share your build failure
information? virtfs-proxy-helper.1 is created inside the fsdev folder.

Pattern:
FOO's PCIDeviceInfo method exit is virtio_FOO_exit_pci(), which calls
virtio_FOO_exit() and virtio_exit_pci().
virtio_{net,serial}_exit() call virtio_cleanup().
virtio_blk_exit() doesn't. Why?
virtio-balloon-pci uses virtio_exit_pci() as exit method. No
virtio_cleanup()?
This patch introduce a fallback mechanism for old systems that do not
support utimensat. This will fix build failure with following warnings:
