Hi all:
I found a discuss about the libvirt shutdown API maybe hang when
shutdown instance in libvirt community,
https://www.redhat.com/archives/libvir-list/2015-March/msg01121.html
I'm not sure that whether there are some risks when we shutdown
instance in nova.
Three questions:
1. Whether acpi is the default shutdown mode in QEMU/KVM hypervisor
when we shutdown instance using libvirt?
2. Whether acpi is asynchronous mode, and qemu-agent is synchronous
mode when we shutdown instance?
3. If the hypervisor use qemu-agent as default shutdown mode, how we
can deal the hanging issue?
Best Regards.
