It appears to only occasionally work. Here is my setup: 2 Identical Machines: Intel(R) Xeon(R) CPU 3050 @ 2.13GHz 8G Ram Debian Lenny 64bit Vanilla 2.6.28.7 kernel (loading kernel modules, not KVM-84 modules) KVM-84 Both machines are attached to an NFS server for the guest files. Trying to transfer hosts using virtio for net and controller. Guests are running 2.6.28.7 with KVM enhancement stuff built in. host started with: /usr/local/kvm/bin/qemu-system-x86_64 -name lenny64/1 - -m1024 -nographic -monitor telnet:localhost:5501,server,nowait - -serial telnet:localhost:5601,server,nowait - -drivefile=/home/lenny64/hdisc.img,if=virtio,cache=writeback,boot=on - -netnic,macaddr=52:54:00:12:00:01,model=virtio-nettap,ifname=tap1,script=/etc/kvm/kvm-ifup-br0 - -daemonize Migration Host Started With host started with: /usr/local/kvm/bin/qemu-system-x86_64 -name lenny64/1 - -m1024 -nographic -monitor telnet:localhost:5501,server,nowait - -serial telnet:localhost:5601,server,nowait - -drivefile=/home/lenny64/hdisc.img,if=virtio,cache=writeback,boot=on - -netnic,macaddr=52:54:00:12:00:01,model=virtio-nettap,ifname=tap1,script=/etc/kvm/kvm-ifup-br0 - -daemonize -incoming tcp:0:4601 Execute migrate tcp:migrationhost:4601 Sometimes it moves without a problem, other times the migrated host hangs without reponse...
