How to share a folder between KVM host and guest using virt-manager?

  • 772

For some time now, I've been using virt-manager to manage my virtual machines. When I want to copy a file from the host to the vm, I have been using scp to copy via ssh over the network. This is kind of tedious, and there must be a way to share a folder similar to VirtualBox. So how can I best share a folder between a KVM host and guest using virt-manager?

  1. You could use 9p sharing as described at http://www.linux-kvm.org/page/9p_virtio .

    Other possibilities include usage of a network file system like NFS or CIFS/Samba.

  2. 9p just works on QEMU KVM Ubuntu 18.04 guest/host

    I'm not sure why it wasn't working before, but now it just works. I basically just add to the QEMU CLI:

    -virtfs local,path=/path/to/share,mount_tag=host0,security_model=mapped,id=host0

    and mount on guest as:

    sudo mkdir /mnt/9p
mount -t 9p -o trans=virtio,version=9p2000.L host0 /mnt/9p

    Exact setup described at: How to run Ubuntu desktop on QEMU?
