[Xen-users] tap2:remus:backup_ip:9000|aio:/path_to_disk.img not working - OSError: [Errno 2] No such file or directory

[Manuel Silva <manuel79silva@xxxxxxxxx>]

Hello,

I'm using Xen (installed from source - "hg clone http://xenbits.xen.org/xen-4.0-testing.hg") on Debian Lenny. Dom0 kernel is 2.6.32-bpo.5-xen-686.

Until now I have successfully ran the Lucid Ubuntu as domU guest, defining disks as (and also as file:):
disk = ['tap2:aio:/home/xen/domains/lucid/disk.img,xvda1,w', 'tap2:aio:/home/xen/domains/lucid/swap.img,xvda2,w']

However, when I try "disk = 
['tap2:remus:backup_ip:9000|aio:/home/xen/domains/lucid/disk.img,xvda1,w',
 
'tap2:remus:backup_ip:9000|aio:/home/xen/domains/lucid/swap.img,xvda2,w']" I have no luck.

Please, can you tell me what's wrong? I have spend so many time googling, but no one seems to address this issue.

Can someone tell me if this happens when installing xen hypervisor directly from deb packages (version 4.0 for Debian squeeze)?

I'll appreciate your help (I'm really stuck).
Thanks in advance.

Best regards,
Manuel Silva
