Re: [one-users] Live migration fail

[Campbell, Bill]

Amier, 
Yes, each KVM node will need to be able to authenticate with each other 
directly, so you'll need to do one of the following: 


* Create a key on each node and ssh-copy-id to each kvm node 
* Use the same key/pair that is used to communicate from OpenNebula to the 
nodes between nodes (i.e. copy the /var/lib/one/.ssh directory to each node). 

We use the second one and it works well, but either should work.

Go to machine 10.23.24.13 and as oneadmin execute:

ssh 10.23.24.19

Most probably you have an old fingerprint for that host in the known_hosts file

Hey All,

I just tried to live migrate a VM, but got a message it failed:

migrate: Command "virsh --connect qemu:///system migrate --live one-810
qemu+ssh://10.23.24.19/system" failed: error: Cannot recv data: Host key
verification failed.: Connection reset by peer

See https://plakbord.cloud.nl/p/hBkytAtcPG627NLYrUS18AAB.

qemu process is running as user oneadmin. user oneadmin can succesfully ssh
to the node. Am I missing something here?

Hi,

yes, you need shared storage for live migration. However, please note that
regular migration will work perfectly and the machine state will be
preserved.

[one-users] (live) migration

[Johan Kooijman]

All,

I'm testing with a ONE right now, and running into an issue I can't
explain. I created VM's on a Ceph datastore, that works fine. Cloning &
snapshotting does. But when I want to migrate a VM to another host:

Mon Aug 11 21:16:24 2014 : Error restoring VM: Could not restore from

Hello

Is it right opennebula currently does not support live migration without 
shared storage? I get this error when trying.

Fri Jul 11 22:14:32 2014 [VMM][E]: migrate: Command "virsh --connect 
qemu:///system migrate --live one-11 qemu+ssh://192.168.122.200/system" 
failed: error: unable to resolve '/var/lib/one//datastores/0/11/disk.1': No 
such file or directory

[Jaime Melis]

Hi Stefan,

Apologies, but I still don't understand if there's a bug here or not.

Could you please open a bug report with instructions on how to replicate
the issue?

Regards,
Jaime

Re: [one-users] Live migration leads to UNKNOWM state

[Stefan Ivanov]

We have 3 datastores with the following ids:
0 - system
101 - ceph_data
102 - system_mc
Live migration happens without a problem when we move the data from the 
datastore directory to the migration target machine datastore directory before 
that.

Hi Stefan,

can you verify if after a while the vms reverts back to the RUNNING state.

Can you also manually confirm that the VM is indeed in the target server (by 
running virsh -c qemu:///system list)

[one-users] Live migration leads to UNKNOWM state

[Stefan Ivanov]

I`m running OpenNebula + CEPH + KVM. When I try to make live migration from one 
host to other everything looks good, no have errors, process is running on 
right host but Virtual machine go to UNKNOWN state(RUNNING(host1) -> MIGRATE -> 
RUNNING(host2) -> UNKNOWN(host2)). In vm log I see this: VM running but it was 
not found. Boot and delete actions available or try to recover it manually, New 
VM state is UNKNOWN.

About my configuration:

Re: [one-users] live migration error

[Jaime Melis]

Hi,
why do you have this line in your oned.conf?


> arguments  = "-t 15 -r 0 kvm -l migrate=migrate_local",
>

I think you should comment that line out.

Jaime

Re: [one-users] Live migration doesn't work _ SOLVED

[Jan Benadik]

  
  
This error description in oned.log is a little bit confused.
The issue was - wrong DNS resolving (or - to be honest - my mistake
in /etc/hosts).

Live migration works well if IP and names are set correctly.

[one-users] Live migration doesn't work

[Jan Benadik]

  
  
Hi all,

I have two nodes with Ubuntu 12.04 Server (KVM) , OpenNebula 3.6.0
(SQLite), shared datastore (NFS), a small number of VM running on
that. If I try to run live migration (via Sunstone), nothing happens
and this error message in oned.log appears :

Tue Jul 17 19:33:26 2012 [ONE][E]: SQL command was: INSERT

  error: columns vmid, last_poll are not unique
  Tue Jul 17 19:33:31 2012 [InM][I]: --Mark--

Can somebody help me where I did something wrong?

Can you give us more information? Like the log files for the VM that
failed and opennebula configuration.

Re: [one-users] live migration fails on ubuntu 11.04

[samuel]

I did a full verification and turned out to be the same problem, a wrong
entry in /etc/hosts. One of the node's entry was not propoerly set
(mispelled domain) and it made impossible for one node's Kvm connect to the
other one.

In order to find out the problem I increased libvirt's debug level to
maximum and I saw thew wrong remote host.domain error.

Thank you very much for the support and apologies for the noise,

Samuel.

Re: [one-users] live migration fails on ubuntu 11.04

[Javier Fontan]

I cannot see any info that leads me to find the problem. Have you
tried migrating VM's manually, that is, using libvirt/kvm manually,
not OpenNebula. Also check that both machines have the same processor
and libvirt/kvm versions.

Re: [one-users] live migration fails on ubuntu 11.04

[samuel]

The error happened to be a wrong entry in the file /etc/hosts, where the
remote node's IP was set to the local one and there were several errors.

However, it is not yet possible to perform live migration on the same
escenario (normal migration works perfectly), I always end up with the
following error:

Can anyone provide help on this issue? How can I debug the live migration?

Re: [one-users] live-/migration not working, uknown error

[Adnan Pasic]

Hey everyone,
sorry for spamming, but I thought it might be a good idea to share with you how 
I found out how to fix this issue!!! It was quite tedious actually.

After reviewing the logging documents, I set the following environment variables

export LIBVIRT_DEBUG=4
export LIBVIRT_LOG_OUTPUTS="1:file:/var/log/virsh.log"

Once that was set, I ran the following to monitor the log file: tail -f 
/var/log/virsh.log

When I ran the live migration this time around, this was the output I received 
on that error

23:35:47.102: error : server_error:7231 : operation failed: migrate failed: 
migrate "tcp:scott:49154"
migration failed

As you can see from this, it was trying to live migrate using the hostname 
"scott" instead of the actual IP once it established the session on both ends 
using ssh. To fix this, I simply modified the /etc/hosts file and included 
scott to resolve to the remote system and voila, it worked like a charm and 
quickly.

Hope this is helpful to anyone getting random UNKNOWN ERROR messages, and 
thanks to the mailing list for helping so selflessly every time!
Keep up the good work!

Regards, Adnan

CHeck out the list archives, in opennebula-2.2 
you need to change qmeu to qemu+ssh in one of the scripts.

If you don't find it, ask again.

[one-users] live migration fails on ubuntu 11.04

[samuel]

Hi folks,

After few tricks to the standard configuration (controller exporting via NFS
opennebula directories to 2 other nodes) seems to work except for one point:
live migration.

When starting live migration (from sunstone web interface), the following
problem appears:

Tue Jun  7 17:12:51 2011 [VMM][I]: Command execution fail: 'if [ -x
"/var/tmp/one/vmm/kvm/migrate" ]; then /var/tmp/one/vmm/kvm/migrate one-131
node1; else  exit 42; fi'
Tue Jun  7 17:12:51 2011 [VMM][I]: STDERR follows.
Tue Jun  7 17:12:51 2011 [VMM][I]: error: Requested operation is not valid:
domain is already active as 'one-131'
Tue Jun  7 17:12:51 2011 [VMM][I]: ExitCode: 1
Tue Jun  7 17:12:51 2011 [VMM][E]: Error live-migrating VM, error: Requested
operation is not valid: domain is already active as 'one-131'
Tue Jun  7 17:12:51 2011 [LCM][I]: Fail to life migrate VM. Assuming that
the VM is still RUNNING (will poll VM).

I'm using qemu+ssh transport with the following version:
$ virsh version
Compilado contra la biblioteca: libvir 0.8.8
Utilizando la biblioteca: libvir 0.8.8
Utilizando API: QEMU 0.8.8
Ejecutando hypervisor: QEMU 0.14.0

Installed version of open nebula is 2.2.

Could anyone shed some light on this issue? I've looked in the Internet and
found some posts relating to qemu bugs but I'd like to know whether can I
get more information about this issue.

Thank you very much in advance,
Samuel.

Re: [one-users] live-/migration not working, uknown error

[Adnan Pasic]

Hey Carlos,

thank you soo much for your help. By now I can finally migrate my machines
normally. The only problem I’, still having is the Live Migration!

This is what the log says:

 

n May 30 12:35:39 2011 [LCM][I]: New VM state is MIGRATE

Mon May 30 12:35:40 2011 [VMM][I]: Command execution fail: 'if [ -x

CPU   : 18

Memory: 524288

Net_TX: 300

Net_RX: 1248

 

 

Is it possible that I somehow messed up the TLS encryption? I configured my
cloud according to this website
http://hpc.uamr.de/wissen/opennebula-workshop/

 

In one point on the website it says: “For live migration and secured VNC,
Transport Layer Security needs to be set up. A step by step guide can be
found in the TLS Setup Guide of Libvirt”.

However, I didn’t dothis part of the tutorial since I didn’t find these
steps in any of the other guides I was reading, including the official
opennebula-guide. Is there something I missed? Do I have to perform this TLS
Setup? A tiny bit of further help would be more than appreciated J

Thanks in advance!

Update: Okay, the issue with "virsh list" is gone. But still the problem
with migration / live migration pertains. 

Do you have to do some extra steps for live migration to work? Do you need
to create TLS keys or something, or is the standard tutorial enough for
everything to work?

 

The error still says: 

[VMM] [E]: Error saving VM state, error: Failed to save domain one-26 to
/srv/cloud/one/var//26/images/checkpoint

 

It seems the folder checkpoint can't get created, or the creation of the
folder is missing somewhere in the scripts, because when I browse through to
the folder /images there is no checkpoint folder inside.

 

I hope those infos are sufficient to narrow down the possible mistakes?

[one-users] live-/migration not working, uknown error

[Adnan Pasic]

Hello everybody,
a new day, a new issue :)
I was able to successfully create my cloud and connect the clusternodes to my 
front-end. Even the test-VM "ttylinux" is running as expected on one of the 
nodes. Or so it seems... 

The problem I am having right now is, that when I start a migration or 
live-migration I get the following errors:

Tue May 24 12:58:32 2011 [LCM][I]: New VM state is MIGRATE
Tue May 24 12:58:33 2011 [VMM][I]: Command execution fail: 'if [ -x

Tue May 24 13:01:17 2011 [LCM][I]: VM is suspended.
Tue May 24 13:01:17 2011 [DiM][I]: New VM state is SUSPENDED

As you can see in the log, I first tried to do a live-migration and then a 
normal migration right afterwards. unfortunately, both tries ended 
unsuccessfully.
I was searching for an error, but all I could find was one strange thing: When 
I initiate a "virsh list" on the node where the VM is running, I don't get any 
results.
Could this be the problem? And if so, how could I resolve it???


Thank you!

Re: [one-users] live migration

Dear Paolo,

You can extend the TM driver to query the core for the list of
physical hosts registered, but it requires a bit of fiddling with the
OCA library.

As an alternative, maybe libvirt hooks can be used to refresh the configuration.

Regards,

I'm using a custom LVM transfer manager driver which needs to refresh
the configuration each time a VM is moved to another host.

Actually my driver works correctly only with off-line migration.

There is a way to obtain the list of opennebula registered nodes from
the transfer manager driver?

Thanks...

Hi there,

since livemigrate functionality assumes shared FS, no transfer manager
call is performed by the OpenNebula core during livemigration.

Hope it helps,

AFAIK, it ssh-launches,  on the machine where the  migration begins, a
command called "migrate"  that (at least for KVM  hypervisor) issues a
virsh "migrate --live" on the destination machine.

Only the devil knows why one of my machine can not be used as starting
point for a migration (and no, I  was wrong in a previous post on this
list, I did not solve it :[ ).

Re: [one-users] live migration using occi-storage fails

[Harder, Stefan]

Hi Javier,

I've added the chmod line to the script but nothing changes. The images
still have 600 permissions instead of 644 needed for a working live
migration. I also restarted one.

By the way, thank you all again for the tutorial!

Stefan

Re: [one-users] live migration using occi-storage fails

[Javier Fontan]

Hello Marco,

To change the permissions of the image uploaded by OCCI server you can
edit $ONE_LOCATION/lib/ruby/cloud/image.rb. Around line 102 there is
this function:

--8<--
def copy_image(path, move=false)
if move
FileUtils.mv(path, image_path)
else
FileUtils.cp(path, image_path)
end
self.path=image_path
end
-->8--

You have to add there a line so it looks like this:

--8<--
def copy_image(path, move=false)
if move
FileUtils.mv(path, image_path)
else
FileUtils.cp(path, image_path)
FileUtils.chmod(0666, image_path)
end
self.path=image_path
end
-->8--

Feel free to change permissions parameter to suit you needs and tell
me if that solves the problem.

Bye

Re: [one-users] live migration using occi-storage fails

[Strutz, Marco]

Hello Javier.

As described in the documentation[1] umask is not set in "/etc/exports":
/srv/cloud  10.0.0.6(rw)

If I upload an image via "occi-storage create " an image will be 
created in "/srv/cloud/images. This image has rw-permission only for 
"oneadmin":"
-rw--- 1 oneadmin cloud

The migration fails for that permissions until I change it to
-rw-r---r- 1 oneadmin cloud
Then the migration works fine.

If I manually create a file as oneadmin in "/srv/cloud/images" via "touch 
testfile", then "testfile" has correct (read) permission which works fine for 
migration:
onead...@b:/srv/cloud/images$ touch testfile && ls -la testfile
-rw-r--r-- 1 oneadmin cloud 0 2010-06-25 10:57 testfile


Occi-server run's as "oneadmin" user:
$ ps aux | grep "ruby"
oneadmin  3038  0.0  0.0  31032  4472 ?SNl  Jun11   8:17 ruby 
/srv/cloud/one/lib/mads/one_vmm_kvm.rb
oneadmin  3049  0.0  0.0  37860  5140 ?SNl  Jun11   9:39 ruby 
/srv/cloud/one/lib/mads/one_im_ssh.rb im_kvm/im_kvm.conf
oneadmin  3063  0.0  0.0  30560  3988 ?SNl  Jun11   7:44 ruby 
/srv/cloud/one/lib/mads/one_tm.rb tm_nfs/tm_nfs.conf
oneadmin  3077  0.0  0.0  30320  3652 ?SNl  Jun11   7:35 ruby

/srv/cloud/one/lib/ruby/cloud/occi/occi-server.rb


I'm clueless about further testing. Could you please assist? I would appreciate 
it.

I have add read permission.. now the live migration works! (My setup uses KVM 
as hypervisor)
Thanks!

onead...@v:~/var/36/images$ ls -la disk.0 
-rw-rw-rw- 1 oneadmin cloud 41943040 2010-06-11 14:13 disk.0


What can I do to have the read-permission automatically set by OpenNebula every 
time a virtual machine is deployed via OCCI? Is this read-only file permission 
a bug in the OCCI implementation, should I open a ticket?

Hello,

Those write only permissions are probably causing that error. xen
daemon uses root permissions to read disk image files. As the
filesystem is nfs mounted these permissions are enforced for root user
and that can cause the problem.

Re: [one-users] live migration using occi-storage fails

Hello,

Those write only permissions are probably causing that error. xen
daemon uses root permissions to read disk image files. As the
filesystem is nfs mounted these permissions are enforced for root user
and that can cause the problem.

Re: [one-users] live migration using occi-storage fails

[Strutz, Marco]

Hello Javier.


The destination node "v" uses a shared storage (via nfs) to access /srv/cloud 
and "disk.0" can be accessed from both machines ("v" and "b"). A symlink seems 
not no be used for the image(s):


id=36:

onead...@v:~/var/36/images$ ls -la /srv/cloud/one/var/36/images/disk.0 
-rw--w--w- 1 oneadmin cloud 41943040 2010-06-11 14:13 
/srv/cloud/one/var/36/images/disk.0



id=38:

onead...@v:~/var/36/images$ ls -la /srv/cloud/one/var/38/images/disk.0 
-rw-rw-rw- 1 oneadmin cloud 41943040 2010-06-11 14:55 
/srv/cloud/one/var/38/images/disk.0

onead...@v:~/var/36/images$  ls -la /srv/cloud/images/2
-rw--- 1 oneadmin cloud 41943040 2010-06-09 10:36 /srv/cloud/images/2

onead...@v:~/var/36/images$ ls -la /srv/cloud/images/ttylinux.img
-rw-r--r-- 1 oneadmin cloud 41943040 2010-03-30 13:57 
/srv/cloud/images/ttylinux.img



The file-permissions seems to be different. Could that be a potential problem?




thanks
Marco

Hello,

Can you check that /srv/cloud/one/var//36/images/disk.0 is accessible
from destination node (I suppose "v")? Also check if that it is a
symlink the target file is readable there.
