[Xen-devel] HVM Migration issues : qemu_flip_buffer

["Shuveb Hussain" <shuveb@xxxxxxxxx>]

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,
