Edits that redefine a domain read the wrong XML: - boot menu/order, vCPU hotplug and QoS read XMLDesc(0), which has no secrets, so every such edit, even on a stopped VM, removed the VNC password from the definition; - console, video, CPU, memory and title/description edits read the live XML, so on a running VM pending changes (e.g. a new memory size) were reverted and runtime state was written into the definition. All of them now read VIR_DOMAIN_XML_INACTIVE | SECURE (PERSISTENT_XML). The console setters take the first graphics device of that definition instead of looking it up by the live type. Disk resize no longer redefines the domain. A running VM's image files grow through blockResize, since qemu-img cannot take the lock QEMU holds; block volumes (e.g. LVM) are grown by the storage pool first and QEMU is then told the new size. Live tests reproduce the losses on a RHEL qemu-kvm host; unit tests check the XML flags, the console setters and the resize paths in CI.
