Hi i tried to perform a live migration of a vm in xen, created from an image shared between two computer nodes in a network through glusterfs located at same path location in both nodes. But the migration failed. Can any one explain me how to setup such a migration?
The server, which was a third node, was exporting the image file of the vm to the same location in both the nodes so that the after migration too the image path remains the same. Mounting the glusterfs was done with option -d disable. Besides as i saw in some article i tried 'tap:aio' instead of 'file' but that resuiltedin failure of booting of the vm from node 1 itself.Also the same xend-config.sxp file is there on both nodes. Saw in the technical FAQ that a live migration using glusterfs by xen is possible, I wonder what i did wrong? Can anyone help me on this trouble? -- Thanks & Regards visco
