Hi folks

I would to know if somebody here use remus with xen-unstable...

I deploy two servers with this tools and see some abnormal behavior.

I have this xen HVM:

kernel = "/usr/lib/xen/boot/hvmloader"
device_model = '/usr/lib/xen/bin/qemu-dm'
memory = 512
shadow_memory = 16
name = "Windows-2003"
disk=['phy:/dev/drbd0,hda,w', 'file:/storage/ISOS/win2003-STR2-i386.iso,hdc:cdrom,r']
on_poweroff = 'destroy'
on_reboot = 'restart'
n_crash = 'restart'

I success create a vm on server xen-0 (my master node).
I success migrate the vm to xen-1 (my slave node).
I came back successfully vm to xen-0.

When I run remus -i 100 Windows-2003 xen-slave, I see the vm on slave node turn paused and vm started on master node.
I see remus continuously send packages to slave node.
But after 3 or 5 minutes, I see the the VM on master node enter in suspend mode without any human intervention! :) I see that state of vm on slave node has change also, to started mode ( xm list show a ---b-- state).
After this point, the vm freeze and everything goes to down!!!!

Some details about my enviroment:

Two Dell PowerEdge T300 with 1 GB of memory (I know! It's not enoght) and 160 GB of hard disk.
CentOS x86_64 with kernel compile against xen-unstable...
I have a isolated network to performer live migration and remus...

I hope to be clear here....

Thanks for any help
