First there are things that can be "hotpluged", which the current design doesn't mention: - NIC cable (sometimes requested on ganeti-user) - CD-ROM images - perhaps CPU (with qemu 1.5 release from yesterday) Second, for an unknown reason, I must use kvm-0.15 on SLES11, which has device hotpluging backported. It would be nice to detect the hotplug feature by parsing some monitor command like "help" etc. Third concerns growing a disk. From my storage point of view, this is the most ideal workflow adding storage to a VM. Mostly considering fully virtualized SAN with shared-block disk template. Think of extra zoning/ACL, mutlipathing, grouping, I/O monitoring for every disk. And a layering violation with LVM inside the VM: the volume manager is the SAN. And last but not least security. the handling of kvm:chroot=true and kvm:security_model=pool should be addressed sooner then later. I wouldn't believe, that all your synnefo VMs run as root? In issue 263 I solved disk-hotpluging with chroot and dropped privileges (works for me). Thanks for listening. Sascha.
