Here's what is spitted by xend.log:

What is wrong?

When I try to start a VM with disk protection offered by Remus, I simply get the following error:
Error: [Errno 2] No such file or directory: 'lsepc32:9000|aio:/dev/vg0/lvol0'

In the config file I have:
disk = ['tap:remus:lsepc32:9000|aio:/dev/vg0/lvol0,xvda,w', 'tap:remus:lsepc32:9000|aio:/dev/vg0/swap,xvdb,w']

The problem remains when I try to use the IP address instead of "lsepc32". Everything works correctly without Remus supplement in "disk=" field. The paths to the LVM partitions are exactly the same on the primary and the backup. I have built everything yesterday from the latest unstable sources.

Where is the catch?

Thankful,
Darko
