If the memory of guest OS is changed constantly, the live migration can not be ended ever for ever.
We can use the command 'virsh migrate-setmaxdowntime' to control the live migration. But the value of maxdowntime is diffcult to calculate because it depends on the transfer speed of network and constantly changing memroy size. We need a easy way to control the live migration.
This patch set add the support of forcing guest to suspend at timeout. With this patch set, when we migrate the guest OS, we can specify a timeout. If the live migration timeouts, auto-suspend the guest OS, where the migration will complete offline.
Ping Hi, eric and Daniel P. Berrange do you have time to review this patch set? Any comment or suggestion to this patch set?
