It's a network device, so I believe you'll need _netdev in your fstab options.

Could you please explain in more detail ? Thanks

I can't resolve
That line works on /etc/fstab of Ubuntu 20.04
That line doesn't work on the /etc/fstab of Linuxmint and Debian

Ubuntu probably stuffed in some hooks elsewhere that Debian / Mint didn't do for some reason or other. Could even be that Ubuntu just stuffs the 9p modules into initramfs (I don't know what Ubuntu does in that regard).

Basically "_netdev" in /etc/fstab tells the mount system to chill out and wait for the network to come up before trying to mount the device.

What shall I add there? Thanks

Something like this:

/hostshare /hostfiles 9p trans=virtio,version=9p2000.L,rw,_netdev 0 0

[satimis]

Something like this:

/hostshare /hostfiles 9p trans=virtio,version=9p2000.L,rw,_netdev 0 0

Tried your suggestion, adding the line on /etc/fstab

~$ cat /etc/fstab

Code: Select all

#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#

# / was on /dev/sda5 during installation
UUID=2eeaa27a-c0f3-4316-a4d0-f537ab9c2ae8 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/sda1 during installation
UUID=BD9F-09F1  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0
/hostshare /hostfiles 9p trans=virtio,version=9p2000.L,rw,_netdev 0 0

Reboot Linuxmint guest.

This time it can reboot without problem. Host /Home/KVM_Share folder seems mounted, but unable to display its content -> files

On Terminal run;
$ sudo mount -t 9p -o trans=virtio /hostshare hostfiles/

Code: Select all

mount: /home/satimis/hostfiles: /hostshare already mounted on /hostfiles.
