Hi Paolo , Jan, Amit Recently we encountered a problem that the virtio-serial can't work after Migration in RH5.5 VM. The bigger problem is, I can't reproduce it. :( It's phenomenon was much like BZ 867366, the usb-table mouse didn't work because the uhci and virtio-serial shard the irq line (using IOAPIC, not MSI). The new interrupt can't be injected to VM because the irq line bit had been set to 1, but the frontend driver never handle it or never know it. Bug 867366 - virtio-serial misses irq delivery on migration https://bugzilla.redhat.com/show_bug.cgi?id=867366 But my qemu is the newest qemu, Both commit 80dcfb8532"virtio-serial-bus: post_load send_event when vm is running" and commit bc6b815d9e " virtio-serial: propagate guest_connected to the port on post_load" are applied. I noticed that Paolo posted another problem maybe have a pertential problem about apic in Comment 23. But this patch https://bugzilla.redhat.com/attachment.cgi?id=635535&action=diff haven't merged into qemu master. Would you give me some clues please? Thanks!
