Hello Everyone, I'm currently looking into how Xen(PV) Disk I/O works. And I want to know how they works in source level. As we know, HVM uses QEMU and the PV / PVHVM uses Dom0 backend driver. And I could find that the Dom0 kernel(driver/block/xen-blkback/blkback.c) do disk I/O in LVM-backed VBD. But, I want to use File-backed VBD rather than LVM-backed VBD. I found that if I use file-backed VBD, then they don't use Dom0 backend driver. So, Can I use backend driver in file-backed I/O? and I want to know how the file-backed VBD works in PV domain. Thank you very much. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
