I run several VMs in Libvirt, host is Debian 12. I’m want to create one dedicated to Samba sharing. What is the best way to expose more disks to a QEMU host? I have 6 SSDs I want to utilize on this VM.
- Creating a filesystem hardware node (virtiofs or virtio-9p)?
- A physical disk exposed to the VM via a Storage hardware node?
- Something more exotic like a zfs storage pool?
Best for me is more about reliability than anything else. I have tried sharing folders before using the Filesystem hardware node and Plan 9 but it was a little wonky when it came to permissions. I may not have set it up right, however.
I am partial to a LVM storage pool.
If there is nothing particularly distinct about any of your drives, then just lump them together into a volume group and add that as a storage pool to libvirt. Then you can divvy them out in whatever capacities you want.
Disclaimer: I don’t have any experience with ZFS, but I suspect it probably serves a similar role and might possibly be just as well or better suited.
