Libvirt does not currently expose anything to change this, other than the fact that _if_ qemu supports a way to change it on the command line, you can use <qemu:command> in your XML to add the extra arguments; or if qemu supports it via a monitor command, you can use 'virsh qemu-monitor-command' to change it at runtime. But again, I don't know enough about the situation to know if qemu even exposes a parameterizable block size for virtio, since no one has previously asked for libvirt to start encoding it into its XML as a formal feature. > > The contents of this e-mail and any attachment(s) are confidential and Disclaimers like this are unenforceable when posting to publicly archived lists, and it is considered poor netiquette to leave them in.
