Fix included in qemu-kvm-rhev-2.3.0-7.el7
Reproduce this bug using the following version: RHEL7.2 host: kernel-3.10.0-302.el7.x86_64 qemu-kvm-rhev-2.3.0-6.el7.x86_64 RHEL7.1 host: kernel-3.10.0-229.12.1.el7.x86_64 qemu-kvm-rhev-2.1.2-23.el7_1.8.x86_64 Steps to Reproduce: 1. boot a guest with a floppy (no image) in src RHEL7.2 host and RHEL7.1 host: /usr/libexec/qemu-kvm -cpu Penryn -name test3 -S -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off -m 1000 -realtime mlock=off -smp 2,maxcpus=4,sockets=4,cores=1,threads=1 -uuid 7347d748-f7ce-448f-8d49-3d29c9bcac30 -no-user-config -nodefaults -rtc base=utc -no-shutdown -boot strict=on -drive file=/mnt/rhel7_1_qcow2,if=none,id=drive-ide0-0-0,format=qcow2 -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -spice port=5901,addr=0.0.0.0,disable-ticketing,seamless-migration=on -k en-us -device qxl-vga,id=video0,ram_size=134217728,vram_size=67108864,vgamem_mb=16,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 -msg timestamp=on -monitor stdio -device intel-hda,id=sound3,bus=pci.0,addr=0x6 -device hda-duplex,id=sound3-codec0,bus=sound3.0,cad=0 -net none -drive file=,if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0 -boot menu=on -serial unix:/tmp/tty0,server,nowait 2. Type "Ctrl+c" into grub command 3. Hit the tab key a few times after the fd0 (don't hit return) grub > boot (fd0) 4. Do migration (qemu) migrate -d tcp:10.66.8.244:5800 5. Carry on hitting the tab during migration Actual results: after step4 and step5, migration is failed and qemu-kvm in dst host quits with: (qemu) qemu: warning: error while loading state for instance 0x0 of device 'fdc' 2015-08-07T03:56:04.069912Z qemu-kvm: load of migration failed: No such file or directory
Test this bug using the following version: RHEL7.2 host: kernel-3.10.0-302.el7.x86_64 qemu-kvm-rhev-2.3.0-15.el7.x86_64 RHEL7.1 host: kernel-3.10.0-229.12.1.el7.x86_64 qemu-kvm-rhev-2.1.2-23.el7_1.8.x86_64 RHEL7.0 host: kernel-3.10.0-123.17.1.el7.x86_64 qemu-kvm-rhev-1.5.3-60.el7_0.11.x86_64 Use the same steps of comment #8 to test, the results is as following: Hosts Machine Type Results ---------------------------------------------- 7.2->7.1 -M rhel7.1.0 pass 7.2->7.1 -M rhel7.0.0 pass 7.2->7.1 -M rhel6.6.0 pass 7.2->7.1 -M rhel6.5.0 pass 7.2->7.0 -M rhel7.0.0 pass 7.2->7.0 -M rhel6.5.0 pass
