It doesn't happen on every guest, but the probability of this error is very high. Yes, I am using qcow images. Zhao, it seems like i just dont want to happen on my host can you please give me as much information about the guest/host and even on how you save the vm? Here are the commands we are using to do the test: qemu-img create -b /share/xvs/img/app/ia32p_UP.img -f qcow2 /share/xvs/var/tmp-img-1 qemu-system-x86_64 -m 256 -net nic,macaddr=00:16:3e:25:b8:87,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/xvs/var/tmp-img-1 migrate “exec:dd of=FILENAME(/share/install/a.img)” qemu-system-x86_64 -m 256 -net nic,macaddr=00:16:3e:25:b8:87,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup -hda /share/xvs/var/tmp-img-1 -incoming stdio FILENAME(/share/install/a.img) Both linux guests and windows guests have the problem. The host is a woodcrest with 8GB memory. The backend file of qcow is on a nfs server. thanks Yunfeng - This SF.net email is sponsored by: Microsoft Defy all challenges.
