[Xen-users] Live Migration Query

Hi,

I''m performing live migration. I see something weird happening that I
cannot
explain:

Once I fire xen migration at the source:

[root@src ~]# xm migrate --live FC8.domU dest
Error: /usr/lib/xen/bin/xc_save 23 3 0 0 1 failed
Usage: xm migrate <Domain> <Host>

Migrate a domain to another machine.

Options:

-h, --help           Print this help.
-l, --live           Use live migration.
-p=portnum, --port=portnum
                    Use specified port for migration.
-r=MBIT, --resource=MBIT
                    Set level of resource usage for migration.

[root@src ~]#

If I do a xm list, I can see the domain here:

[root@src ~]# xm list
Name                                        ID   Mem VCPUs      State
Time(s)
Domain-0                                     0   499     1     r-----
1517.6
FC8.domU                                     3   500     1     -b----
3.6


While at the destination, I see a hanging domU as :

[root@dest xen-images]# xm list
Name                                        ID   Mem VCPUs      State
Time(s)
Domain-0                                     0   502     1     r-----
1646.1
FC8.domU                                     3   500     0     -bp---
0.0


Can anyone help me with this save failed problem and it will also be great
if anyone can explain me what exactly happened here.

Thanks,
Asim

Check your Xen logs (/var/log/xen/*) on both sides - probably, some 
incompatibility - are Xen versions on both sides the same?

Re: [Xen-users] Live Migration Query

Am using the same Xen version on both machines:

These are the last few lines from the log:

Try to clear the log files (but not remove), do a migration, and then 
look for errors.

Is the storage available from both machines?

Re: [Xen-users] Live Migration Query

Well, I cant see any error. I truncated the file and the log is attached.
The storage is nfs shared. The VM is on file based disks on this shared
storage at the source.
I cannot find any errors in the log files.

What version of Xen are you using? I had a similar problem when trying to 
migrate a 32bit guest under a 64bit host with Xen 3.04. Xen 3.2 solved this 
issue for me.

Re: [Xen-users] Live Migration Query

I''m using Xen 3.1.4. It is a 32 bit host on a 32 bit kernel for dom0
but the
machine is 64 bit.
Did you get this error as well => ERROR Internal error: Couldn''t
enable
shadow mode

I thought it has something to do with PAE mode.

Thanks,
Asim
