I'm using libvirt 0.10.2 and I had qemu-kvm 1.1.1 running all my VMs. I used libvirt's managedsave command to pause all the VMs and write them to disk and when I brought up the machine again I had upgraded to qemu-kvm 1.1.2 and attempted to resume the VMs from their state. It unfortunately fails. During the life of the VM I did not attempt to adjust the amount of memory it had via the balloon device unless of course libvirt did behind the scenes on me. Below is the command line invocation and the error: LC_ALL=C PATH=/bin:/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin HOME=/root USER=root QEMU_AUDIO_DRV=spice /usr/bin/qemu-kvm -name expo -S -M pc-1.0 -cpu Penryn,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -uuid 19034754-aa3f-9671-d247-1bc53134e3f0 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/expo.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x4 -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/expo.img,if=none,id=drive-ide0-0-0,format=raw,cache=none -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=23,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:0b:29:d9,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -spice port=5901,addr=127.0.0.1,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -incoming fd:20 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 char device redirected to /dev/pts/7 qemu: warning: error while loading state for instance 0x0 of device 'ram' load of migration failed Let me know what specifics I can provide to make this easier to debug.
