What are the CentOS versions of your host and guest?
As far as I know, virtio disks have never supported rescan from inside the
guest and so there isn't the corresponding "rescan" special file.
I found this old, but interesting thread:
https://forum.proxmox.com/threads/extend-rescan-virtio-disk-in-guest-vm.7989/
Can you confirm your host libvirt version and your guest kernel are ok with
what is referred?
In case you could try with the qemu monitor command.
See also here for a reference of possible qemu monitor commands:
https://qemu-project.gitlab.io/qemu/interop/qemu-qmp-ref.html
And here for consideration regarding RH EL 6 host:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/virtualization_administration_guide/sub-sect-domain_commands-using_blockresize_to_change_the_size_of_a_domain_path
Also here you find reference of command to issue, but somehow the syntax
changes depending on components' versions:
