Hi, I am using an iSCSI SAN and running Xen 3.1.0 (Ubuntu Gutsy, AMD64). I am also using LVM+CMAN+CLVMD, so the device paths are all the same on different nodes. When I migrate a HVM domain from Node-1 to Node-2, The domain migrates, but does not run. The "xm list" command on Node-2 does not list any state, its all dashes. "------". When I try to migrate the domain back to Node-1, where it belonged originally, I get this error in the logs: xc_save: timed out waiting for qemu to switch buffers I understand this is from the function qemu_flip_buffer() in xc_save.c. Anyone has a clue as to what might be wrong here? Regards, -- Shuveb Hussain. Money has nothing to do with Happiness, But, Poverty has a lot to do with Sorrow.

Anyone has a clue as to what might be wrong here?That often means that qemu-dm has died. The earlier symptom might be a clue that qemu-dm never started properly at all.
