In the previous version Windows balloon driver didn't keep the current balloon size between hibernation/resume and restarts.
The problem was fixed by keeping the current balloon size between restarts and hibernation/resume cycles and adjusting the balloon size according to this value.

another addinfo: test this with version 'virtio-win-1.4.0-1.el6.noarch' not hit this issue.maybe is a regression problem.

Vadim i both 'used (qemu) system_reset' and 'reboot' to test this issue. both hit this probelm. test 2 senarios for this bug. version: host: # uname -r 2.6.32-285.el6.x86_64 # rpm -q qemu-kvm qemu-kvm-0.12.1.2-2.295.el6.x86_64 senario 1) guest: kernel:2.6.32-285.el6.x86_64 test on rhel6.3 guest five times for this senario boot rhel6.3 guest-->change balloon size ---> reboot guest --->the balloon size changed to the correct value. senario 2) guest:kernel 2.6.18-325.el5 test on rhel5.8 guest boot rhel5.8 guest--->change balloon size--->reboot guest ---> the balloon size changed to the correct value . addinfo, 1)all the tests both use '(qemu)system_reset' and 'reboot' guest to test. 2)test win2008r2-64 guest five times ,three times can hit this probelm. Also hit the similar issue on win2k8-64 after resume from S3, following is the details: kernel-2.6.32-279.el6.x86_64 qemu-kvm-0.12.1.2-2.295.el6.x86_64 virtio-win-prewhql-30 Steps: 1. Start guest with CLI: /usr/libexec/qemu-kvm -m 7G -smp 3 -cpu Penryn,+x2apic -usb -device usb-tablet -drive file=win2k8-64-killed.qcow2,format=qcow2,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,id=hostnet0,script=/etc/qemu-ifup0 -device e1000,netdev=hostnet0,mac=90:10:1a:75:50:03,bus=pci.0,addr=0x4 -uuid ee19a2c1-ecf0-4073-bcf0-08304313f391 -rtc base=localtime -no-kvm-pit-reinjection -monitor stdio -name win2k8-64-fun -spice disable-ticketing,port=5931 -vga qxl -bios /usr/share/seabios/bios-pm.bin -device virtio-balloon-pci,addr=0x6,bus=pci.0,id=balloon1 -chardev socket,id=111a,path=/tmp/monitor-win2k8-64-balloon-30,server,nowait -mon chardev=111a,mode=readline 2. evict memory: (qemu) balloon 1024 (qemu) info balloon balloon: actual=1024 3. sleep guest 4. Wake up guest and check the memory: (qemu) info balloon balloon: actual=7168 Actually result: Memory come back to the Max value 7168M instead of 1024M. Best Regards, Dawn Postponed to RHEL6.5, due to capacity constraints, and under the assumption that no customer is using virtio-win ballooning. Should be fixed in build 35 http://download.devel.redhat.com/brewroot/packages/virtio-win-prewhql/0.1/35/win/virtio-win-prewhql-0.1.zip Verified the bug on virtio-win-prewhql-0.1-35 Reproduced the issue on virtio-win-prewhql-0.1-30 steps, 1.start guest, /usr/libexec/qemu-kvm -m 7G -smp 3 -cpu Penryn,+x2apic -usb -device usb-tablet -drive file=win2k3-64.qcow2,format=qcow2,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,mac=90:10:1a:75:50:03,bus=pci.0,addr=0x4 -uuid `uuidgen` -rtc base=localtime -no-kvm-pit-reinjection -monitor stdio -name 2k3 -spice disable-ticketing,port=5931 -vga qxl -bios /usr/share/seabios/bios-pm.bin -device virtio-balloon-pci,addr=0x6,bus=pci.0,id=balloon1 -chardev socket,id=111a,path=/tmp/monitor-win2k3-64-balloon-30,server,nowait -mon chardev=111a,mode=readline 2. evict memory: (qemu) balloon 1024 (qemu) info balloon 3. sleep&wake guest or reboot guest Expected results,the balloon value is 1024 Actual results,the balloon value is 1024 So,the bug has been fixed on virtio-win-prewhql-0.1-35,thanks.
