Hi all,
We met a problem on Windows live migration handing. We use Xen 3.3’s
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:
Many thanks!
