[CRIU] Fwd: Criu Restore Error

[Priyanka Naik]

priyanka at priyanka-Lenovo-G510:~$ sudo mount -t 9p -o
trans=virtio,version=9p2000.L hostshare /tmp/host_files
mount: wrong fs type, bad option, bad superblock on hostshare,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
