Hello, I have the latest xen-unstable which I pulled from the mercurial repository today (changeset:7793:090e44133d40 from 14/11). I tried to use migration and it failed.(details are below). I want to know if this has to do to definitions in /etc/xen/xend-config.sxp on the side who initiates the migration (or maybe on the side to which we want to migrate to ???) I would appreciate if anybody will comment on this: How should relocation parameters in /etc/xen/xend-config.sxp on the "client" (the one who initiates the migration) be set (if at all)? Should any relocateion parameters be set on the "server" (the side we want to migrate to? ) The relocateion paramters I am talking about are: xend-relocation-server (I assume it should be "yes" xend-relocation-port xend-relocation-address '''' xend-relocation-address localhost should "xend-relocation-address localhost" be commented ? or should "xend-relocation-address set to some address ? Should "xend-address localhost" be commented ? (as I understand, specifying ''localhost'' for xend-address prevents remote connections.). What I tried is running the following commands: xm migrate myDomU 127.0.0.1 This hangs (does not return to prompt) and from a different terminal xm-list shows: Domain-0 0 59 1 r----- 101.8 migrating-myDomU 3 32 1 ---s-- 20.4 When I try: xm migrate myDomU 10.0.0.25 where 10.0.0.25 is a different machine on the same LAN (conencted through a hub) I get: Error: can''t connect: Connection refused (which is "ECONNREFUSED" errno). Any ideas ? IB _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello,
Thanks.
1) I am working on 32 bit x86.
2) I triled with the default, unchnaged xend-config.sxp (taken from
/dist/install/etc/xebn)
I ran:
tail -f /var/log/xend.log
xm migrate myDomU 127.0.0.1
I want to add something:
I think my memory division for domo and domU is OK,
but I am not sure:
This was done on a machine with RAM 128 MB.
in grub.conf I have this allocation:
kernel /boot/xen.gz dom0_mem=60000
and in myDomU config file I have mempry set to 32 MB thus:
kernel ="/boot/vmlinuz-2.6.12.6-xen0"
memory = 32
name = "myDomU"
nics = 1
disk =
[''file:/work/dev/tests/feodra_xe_img/fedora.img,sda1,w'']
root = "/dev/sda1"
This is the log I got: (seems to be a problem with restore:
I see "Failed to increase reservation" and other error messages)

Hello, Did anybody succeeded with migration (to local host and/or to other machines running Xen) with default xend-config.sxp with xen-unstable on last week? I begin to suspect that maybe there is a bug somwehere in migration ??

Hi Ian, I just downloaded a new source of xen-unstable today. Maybe the same problem occured to me. I guess for security reasons, migration between hosts is disabled. You have to check your /etc/xen/xend-config.sxp. 1) relocation server (for transferring domains) must be enabled (should be default): #(xend-relocation-server no) (xend-relocation-server yes) 2) relocation server shall accept connections from the network: (xend-relocation-address '''') #(xend-relocation-address localhost) Hope it helps you.

Hello, Thanks. If I am not wrong , the default xend-config comes with these relocation parametrs set as you sussgested (I am far from the Xen machine right now for the next twelve hours). You said:>Maybe the same problem >occured to me.may I ask : 1)Did you/anyonne else succeeded in migrating to another machine with xen-unstable from last week? 2)Did you/anyonne else succeeded in migrating to local machine with xen-unstable from last week? As far as I underastand , there is no reason for "xm migrate domU 127.0.0.1" to fail when using xen-unstable with the default xend-config.sxp. Regards, IB _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, I was able to migrate my VM to localhost without any issues. xen-unstable source was downloaded on 8 Nov. The command I issued was #xm migrate 4 127.0.0.1 <http://127.0.0.1> 4 is DomID This migrated successfully, only difference I found was that, it changes the DomID (Ofcourse!!)

Hi, To tell the truth, I am really confused. I tried migration to local host on two machines after installing from scratch with with no success. (even not migrating to local host). I suspect it may be something silly which I do but I cannot put my finger on it. Or maybe it is really a BUG ,since I did not get a positive answer from anybody who succeeded with migration from a Xen Unsable version from last week : Are you awake , Xen Users? :) I want to verify that it is not a memory problem : maybe I should allocate less mem to the domains than I do. So can you please tell me what is the memory allocation metrics you use: I mean 1) what is the total RAM on the host which performs the migration 2) how much memory is allocated in the grub.conf (menu.lst) or lilo conf for domain 0 (it is in the dom0_mem paramer) 3) how much memory is allocated for your domU. BTW: may I ask: did you try to migrate to a different machine ?

Hi,
Regarding Ian Brown question about Migration:
I have a version of Xen Unstable from yesterday and
migration both to local machine and to a Dom0 on
a different machine works.
You said the error you get is:
"Error: can''t connect: Connection refused"
(which is "ECONNREFUSED" errno).
I assume with high level of certainty that this problem
can be traced to setupRelocation() method in
tools/python/xen/xendf/relocate.py.
This is how this method starts:
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((dst, port))
except socket.error, err:
raise XendError("can''t connect: %s" % err[1])
The default relocation port is 8002. (look at /etc/xen/xend-config.sxp).
Make sure that you "xend-relocation-port 8002" is
uncommneted and you are litening on this port.
The "xend-address localhost" should be commeneted to enable
remote connections.
You can verify this by running that running this python snippest solely
(replacing the dst with the right IP), or simply "telnet dst port"

Rami Rosen

Hi,
Thanks Rami, you were absolutely right !
I had in xend-config.sxp
...
#(xend-relocation-address '''')
(xend-relocation-address localhost)
...
running:
netstat -nl | grep 8002
gave
tcp 0 0 127.0.0.1:8002 0.0.0.0:*
LISTEN
and trying from a different machine:
xm migrate 1 MY_MACHINE_IP_ADDR
gave
Error: can''t connect: Connection refused
and also , from that other machine:
telnet MY_MACHINE_IP_ADDR 8002
Trying MY_MACHINE_IP_ADDR...
telnet: connect to address MY_MACHINE_IP_ADDR: Connection refused
//////////////////////////////////////////////////////////////////////////////
So I changed xend-config.sxp thus:
(xend-relocation-address '''')
#(xend-relocation-address localhost)
and then
netstat -nl |grep 8002
tcp 0 0 0.0.0.0:8002 0.0.0.0:*
LISTEN
LISTEN
and also
telnet MY_MACHINE_IP_ADDR 8002
was OK. (connection started)
and also migrating from a different machine worked!
Thanks again,
IB
