Hello, I'm trying to migrate a vm from a fedora 11 host to another fedora 11 host. Both hosts are on the same subnet. Both machines have identical architectures. We use an nfs shared storage mounted, but both machines also have their own hard drives. I get the machines up and running alright. Here's the printout of virsh when I try to do the migration. # virsh list Id Name State ---------------------------------- 1 windowsxp running 2 potato running # virsh migrate 1 qemu+ssh://prodigy/system Password: error: operation failed: failed to start listening VM On the other machine, the log file that gets created under /var/log/libvirt/qemo/windowsxp.log LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -S -M pc -m 512 -smp 1 -name windowsxp -uuid 24d2fd62-ed4f-a321-e264-200b347cfa6c -monitor pty -pidfile /var/run/libvirt/qemu//windowsxp.pid -localtime -no-acpi -boot c -drive file=/var/lib/libvirt/images/windowsxp.img,if=ide,index=0,boot=on -drive file=/aml/iso/windows_xp_sp3.iso,if=ide,media=cdrom,index=2 -net nic,macaddr=54:52:00:01:f1:06,vlan=0 -net tap,fd=19,vlan=0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 -soundhw es1370 -incoming tcp:0.0.0.0:49159 qemu: could not open disk image /var/lib/libvirt/images/windowsxp.img I would think that the virtual machine should copy from the one machine to the other. Isn't libvirt supposed to copy the image file? What's even stranger, I've been trying this for awhile. It's failed every time, except once when it succeded. I don't know what made it succeed in that case and fail in all the other cases. Thanks.
