Hi, Dear All I was trying to do the live VM migration with Xen. There are two hosts, host1 and host2. Both hosts has Fedora Core 6 as the host operating system. And I created a XEN guest, XEN1, at host1. Now I want to migrate XEN1 from host1 to host2 using the live migration feature of XEN. First, I edited /etc/xen/xend-config.sxp on host1 and hosts to: #(xend-unix-server yes) (xend-relocation-server yes) (xend-relocation-port 8002) (xend-relocation-address '') (xend-relocation-hosts-allow '') #(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$') Then, I restart xend on host1 and host2: service xend restart Then, I exported the /var/lib/xen/images on host1 via NFS and mount this directory to host2. And the mount is successful. After that I start XEN guest on host1: xm create xen1 However, I found that the Virtual Machine Manager of FC6 didn't work. It said: Unable to open to a connection to the Xen hypervisor/daemon. Verify that: -A Xen host kernel was booted -The Xen service has been started. But when I use "xm list", Domain-0 is running, and xen1 is blocked. Finally, I run "xm migrate -l xen1 host2", it failed, the error message is: Error: /usr/lib64/xen/bin/xc_save 4 1 0 0 1 failed. Anybody know how to slove this problem? Thanks a lot. Regards, angel -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
