Have you used -M rhel6.0.0 on both src/dest (you should)? Is 6.0 <-> 6.1 releases work and only 6.2 has an issue? (In reply to comment #1) > Have you used -M rhel6.0.0 on both src/dest (you should)? Hi, Dor Sorry for reply late because just coming back from the Chinese National Holiday. Yes, I used -M rhel6.0.0 on both src/dest host. > > Is 6.0 <-> 6.1 releases work and only 6.2 has an issue? Migrate 6.0 -> 6.1 : Succeed, usb mouse works well after migration. Migrate 6.1 -> 6.0 : Failed migration on dest side: (qemu) qemu: warning: error while loading state for instance 0x3f0 of device 'fdc' load of migration failed Hmm. Failed to reproduce this locally so far. Having two mouse pointers sounds like we are not in absolute mouse mode any more. Can you please check what the "info mice" monitor command prints before and after migration? Image file name suggests this is a win7 guest. Is this correct? Does this happen with other guests (rhel 6.2, winxp) too? What machine type (-M rhel6.x.0) did you use for the 6.2 <=> 6.2 test (comment #7)? Does it make a difference whenever you use rhel6.1.0 or rhel6.2.0 ? (In reply to comment #10) > Hmm.

Hi, Amit Yes, I tried win7 and RHEL6.2 guest, both have this problem. > > What machine type (-M rhel6.x.0) did you use for the 6.2 <=> 6.2 test (comment > #7)? Does it make a difference whenever you use rhel6.1.0 or rhel6.2.0 ? When migrating between 2 rhel6.2 host, I use rhel6.2.0. Let me double check when using "rhel6.1.0" later and update here. Bingo! ps/2 mouse active instead of usb tablet, suspected something like this. With rhel6 guest I can reproduce it. Investigating. Things return back to normal after activating the tablet using the "mouse_set" monitor command. Created attachment 527675 [details] 0001-usb-hid-activate-usb-tablet-mouse-after-migration.patch scatch build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=3702585 *** Bug 746604 has been marked as a duplicate of this bug. *** Patch in Comment 14 works fine for rhel6.2 guest migration with -M 6.2.0 Reproduce on qemu-kvm-0.12.1.2-2.196.el6.x86_64 before migration: (qemu) info mice * Mouse #1: QEMU USB Tablet Mouse #0: QEMU PS/2 Mouse after migration: (qemu) info mice Mouse #1: QEMU USB Tablet * Mouse #0: QEMU PS/2 Mouse Verify on qemu-kvm-0.12.1.2-2.199.el6.x86_64 before migration: (qemu) info mice * Mouse #1: QEMU USB Tablet Mouse #0: QEMU PS/2 Mouse after migration: (qemu) info mice * Mouse #1: QEMU USB Tablet Mouse #0: QEMU PS/2 Mouse Test with "-M 6.2.0", "-M 6.1.0", "-M 6.0.0", patch works fine.
