From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Best method for disk sharing in QEMU/Libvirt? (self.linux)

submitted 1 year ago by Nullpointer to c/[email protected]

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.

Thank you, very helpful! In this case the vm is just a file server. The bulk of the traffic is for Time Machine. In the past I had the host manage samba shares on btrfs but was exploring delegating that to a vm and playing with zfs. This is all home network admin fun, and your response gave some good info.
