I use glusterfs3.3.0 as KVM storage, but I have found the performance in vm is poor.I replied with my phone, but didn't notice that I replied directly. For the benefit of others:I have the same problem as the below bug: https://bugzilla.redhat.com/show_bug.cgi?id=842254 the I/O performance is < 1% of my hardwares capability. Hopefully work on buffering and other tuning will fix this ? Or maybe the work mentioned getting qemu talking directly to gluster will fix this?
Or change your perspective. Do you NEED to write to the VM image?I write to fuse mounted GlusterFS volumes from within my VMs. The VM image is just for the OS and application. With the data on a GlusterFS volume, I get the normal fuse client performance from within my VM.
