Hi all: As we know, "32768~61000" are random ports reserved for customized use. 49152-49215 is in that range. We think that setting migration port into this range, is a little risky. Because other applications may have already taken these ports before we migrate a guest, then the migration job would fail.
So, why did we choose "49152-49215" as the default port range for migration, any specific purpose? Thanks in advance.
I'm not sure why this specific port range was chosen and it doesn't really matter since we can't change the default. But you can configure libvirtd (in /etc/libvirt/qemu.conf) to use any range you wish. Jirka
