Do you have some comparasion of IO performance on thin pool vs. qcow2 file on fs? In my case each VM would have its own thin volume. I just want to overcommit disk-space.

...w cpu usage ~40%) nas => dom0 (TSO=0) 860Mbps (stable result, high cpu usage ~170%. some times can stable at ~2000Mbps, not sure how to reproduce) Similar result can be observed when talking to another linux domU. However, linux domU can generally achieve better performance than dom0. 3. As a comparasion, here is a iperf test between linux domU and dom0. dom0 => lin domU ~10300Mbps lin domU => dom0 ~13500Mbps 4. file transfer from external host to nas PS: Here the bottleneck is the network rather than the disk. NFS: 50MB/s FTP: 102MB/s I''m not quite sure about how much perf to exp...

Dumb Question... What is the value of a Domain in a small Samba-server environment? Why is it better than a "security = user"? What are the drawbacks of a Domain in a small (singleserver even) environment? Thanks!

Hello, as usual, I'm few years behind trends so I have learned about LVM thin volumes recently and I especially like that your volumes can be "sparse" - that you can have 1TB thin volume on 250GB VG/thin pool. Is it somehow possible to use that with libvirt? I have found this post from 2014: https://www.redhat.com/archives/libvirt-users/2014-August/msg00010.html which says
