Thanks it helped but am not sure of the reason.
The log contains -

for c in cfg['cpus'].split(','):
AttributeError: 'list' object has no attribute 'split'
Hence, I commented out the following from the DomU's configuration file
-
#cpus = "0"
#vcpus = 2
Now I can do save/restore (I have 1 cpu on my machine right now)

Subject: [Xen-users] xm save/restore failing; ideas ?
Hi,
I had save/restore working earlier and am not sure what
is causing
it to fail now -
=====================================
[root@localhost ~]# xm list
Name ID Mem VCPUs State
Time(s)
Domain-0 0 257 1
r-----
74.3
debian_3.1 9 128 2
-b----

[root@localhost ~]# xm save debian_3.1 /tmp/t
[root@localhost ~]# ls -l /tmp/t
-rwxr-xr-x 1 root root 134368760 May 23 13:39 /tmp/t
[root@localhost ~]# date
Wed May 23 13:39:45 IST 2007
[root@localhost ~]# xm list
Name ID Mem VCPUs State
Time(s)
Domain-0 0 257 1
r-----

[root@localhost ~]# xm restore /tmp/t
Error: Restore failed
Usage: xm restore <CheckpointFile> [-p]
Restore a domain from a saved state.
-p, --paused Do not unpause domain after
restoring it
=====================================
Any thoughts/sugegestions ?
Have a look at /var/log/xen/xend.log, and see if it's got something
useful in there. Most likely, the save-file is messed up somehow. [It
looks about the right size, a few meg above 128M, but it doesn't mean
that there isn't something wrong in there...]
