SSHFS and NASS Shares in Libvirtd/Qemu
In this article, we will discuss how to use SSHFS and NASS shares in Libvirtd/Qemu, with a focus on the global topic of managing and accessing remote storage in a virtualized environment.
What is SSHFS?
SSHFS (Secure SHell FileSystem) is a filesystem client based on the SSH protocol. It allows you to mount a remote filesystem via SSH and interact with it as if it were a local directory. This can be useful for accessing and managing remote files and directories in a secure and convenient way.
Setting up SSHFS
To use SSHFS, you will need to have SSH access to the remote server and the sshfs package installed on your local machine. You can install it using your package manager, for example:
sudo apt-get install sshfs
Once you have the sshfs package installed, you can mount the remote directory using the following command:
sshfs user@remote:/path/to/remote/directory /local/mount/point
Replace user@remote with your SSH login credentials and /path/to/remote/directory with the path to the remote directory you want to mount. /local/mount/point is the local directory where the remote directory will be mounted.
Using SSHFS with Libvirtd/Qemu
To use SSHFS with Libvirtd/Qemu, you will need to create a NASS share and mount it using SSHFS. Here's how to do it:
- Create a NASS share on the remote server and make sure it is accessible via SSH.
- Mount the NASS share on the local machine using SSHFS.
- Create a Libvirtd/Qemu storage pool that points to the mounted NASS share.
- Add a storage volume to the storage pool and attach it to the virtual machine.
Code Example
Here is an example of how to create a Libvirtd/Qemu storage pool that uses a NASS share mounted with SSHFS:
# Create the storage pool
virsh pool-define-as my-nass-pool --type dir --target /local/mount/point
# Start the storage pool
virsh pool-start my-nass-pool
# Add a storage volume to the pool
virsh vol-create-as my-nass-pool my-nass-volume 10G
# Attach the storage volume to the virtual machine
virsh attach-device my-vm --driver qemu --file /path/to/my-nass-volume.qcow2 --subdriver qcow2
