Logs attached. xenstore-ls below.I had two domains running. One with root-fs using tap:aio:/mnt/instance_image_store_1/3811, and a second dom-U on tap:qcow:/mnt/instance_image_store_0/3811.qcow, which was set up as a COW overlay of image file /mnt/instance_image_store_0/3811 (not the same as the tap:aio: image for the first domU - the directories differ in their last digit). Then both dom-U's also had/have a swap partition (vbd phy:) on /dev/VolGroupDomU/instance_swap_store_1/0 and a second vbd phy: on /dev/VolGroupDomU/instance_ephemeral_store_1/0. The 'xenstore-ls' also shows qcow:/mnt/instance_image_store_2/3811.qcow which I don't think should be there at all (maybe from a previous failed attempt). Could this be related to tap:qcow: mounts not umounting? I previously set up a test tap:qcow: device in dom0 using 'block-attach 0 ...', then mounted it, which seemed to work OK. However 'umount ...' then hung (seemingly in the kernel - I had to reboot to get rid of it).
