[Xen-devel] xm migrate --live fails

hi all,

i would like to do a live migration to another host which fails. bellow the
console output.

host    : debian squeeze 6.0.2.1 amd64
kernel  : 3.0.0
hw      : hp dl 320g5

any glue on that behavior?

by the way, I use it cause it should be a test for remus. remus doesn''t
work
too! the console output below as well.

thanks a lot guy''s ...

walter

[Xen-users] Re: [Xen-devel] xm migrate --live fails

Walter,
 This post IMO should go to xen-users only and not xen-devel.

that said, check the configuration in /etc/xen/xend-config.sxp especially
(xend-relocation-server yes)
(xend-relocation-hosts-allow ....

Re: [Xen-users] RE: [Xen-devel] xm migrate --live fails

HI Walter,

> root@srv-ldeb-xen001:/etc/xen# xl save 9
You''re missing a third parameter... the name of the file where the
status should be saved to.

Should read:
# xl save <domain> <savefile>

This error message here is very misleading indeed:
> Unable to get config file
...or plain wrong :)


Cheers
Carsten

Hi Walter,

Try save, not safe...with V

That works well, given that everything is configured properly:


[root@xen12 ~]# xl save lego lego.sav
Saving to lego.sav new xl format (info 0x0/0x0/589)

[root@xen12 ~]# ll lego.sav

[root@xen12 ~]# xl restore lego.sav
Loading new save file lego.sav (new xl fmt info 0x0/0x0/589)
 Savefile contains xl domain config
Parsing config file <saved>
Daemon running with PID 3713

[root@xen12 ~]# xl console lego

CentOS Linux release 6.0 (Final)
Kernel 2.6.32.43.pvops-1.el6 on an x86_64

Re: [Xen-devel] xm migrate --live fails

You''re missing the second parameter to save, the filename to which to
save.

Try again with the proper command and please also include the output 
from /var/log/xen/xend.log.

You shouldn''t mix xm and xl! They cannot be used at the same time.

Have you configured the relation server & hosts in /etc/xen/xend-config.sxp?

(xend-relocation-server yes)
(xend-relocation-hosts-allow ''^localhost$
^localhost\\.localdomain$'')

Check /var/log/xen/ as well for some extra info. Also, this is more 
suited for the xen-users mailing list :)

[Xen-users] RE: [Xen-devel] xm migrate --live fails

hi pasi,
hi nathan,

i close the thread "xm migrate --live fails"!

solution:

after I reinstalled the second host (receiver) everything worked ok. I dont
know what happened since I install my xen hosts by bash script, so every
host in my environment should be the same to avoid unconsents result while
trace and error.

all commands

- xm/xl migrate
- xm/xl save
- xm/xl restore

as well as remus does work again perfectly, inclusive disk replication.

thanks a lost for your help and time!

walter.
