Hi, As to the previous email (Virtual Machine Migration Problems with Fedora Core XEN), I have some ways to solve the problem. To enable the Virtual Machine Manager to run, after changing the configuration file /etc/xen/xend-config.sxp, The line #(xend-unix-server yes) shouldn't be commented. However I have some new problems when I did the migration. During the migration process, I can use "xm list" at source and destination hosts to show what domains are running. It shows that XEN1 (the guest domain that I want to migrate from source to destination host) is migrated, since at source host, the domain name, XEN1, becomes migrate-XEN1, and at destination host, one more domain, XEN1, appears. But after the migration is finished, both of the two hosts don't have domain XEN1. As far as I know, the virtual machine migration just migrate XEN1 from one host to another. XEN1 should be at the destination host after the migration completes. right? It seems that XEN1 flies away. ?? Or maybe the migration is not successful. The domain list shown by "xm list" are not real. ?? And at the source host, I can use "xm create -c XEN1" to start the domain XEN1 again. really weird !! And it can be migrated to the same destination again. Anybody has similar experiences before or know how to slove this problem? Thanks for you time.
