Does virtink support mount a PVC into some path in vm?

[weixiao-huang]

Sometimes, we want to mount a PVC into the VM to persistent some data. For example, we have a PVC called my-data and we want to mount it into /data path into vm. So does virtink support it? To do this thing, I think there're two hands:

1. mount volume from host machine into VM (hostPath or local-path-provisioner)
2. mount volume from network (directly mount ceph rbd from network into VM) So does virtink support one of the two method above?

yes, virtink already support PVC, 1) for Block PVC you can use it directly, 2) for filesystem PVC, need make sure a disk image file named asdisk.img in PVC root path. a better way is use DataVolume, which will create disk.img for filesystem PVC root path automatically. this is an example VM with Datavolume.

But how to specify the volume's mount path in the VM? I've seen the docs about the DataVolume but it seems that I didn't find some examples about specifying the volume mount path

@weixiao-huang To mount a disk to a path inside a VM, you have several options:

• Use the mount command to mount the disk manually inside the VM
• If you want the mount to be persistent across reboots, you could add it to the /etc/fstab file
• You could also use cloud-init to do the mounting when booting the VM, please refer to cloud-init doc for how to do that

All Virtink could do is provide a volume as a VM disk to the VM, but the mounting part should be taken care of inside the VM.

@weixiao-huang I'm closing this issue, feel free to reopen it if you want.
