Hi all,
We met a problem on Windows live migration handing. We use Xen 3.3s full
virtualization mode to create and migrate the Windows VMs based on QEMU. The
error information is as follows:
1) log said the migration was successful. However, that migrated VM on the
destination hanged wherein CPU utilization kept about 48%.
2) Using XenTrace, found that the loop consisting of three events as follows:
Event 1: VMEXIT by io instruction;
Event2: VMEXIT by acpi accesses;
Event3: VMEXIT by virtual interrupt.
We guess that acpi support in Xen qemu-dm was not compatible with Windows in the
migration process.
Would you have any suggestions?
We also took a look at the below discussions as follows:
