[ovirt-users] Re: How to add vnc console for ovirt-engine VM

Hi Xu,

please direct question ovirt user's list rather then directly to a specific
person as others may be able to assist you.

Thanks,

[Dafna Ron]

Correct email for this would be users@ovirt.org (added)

I also suggest that you attach the logs from the engine and the host
machines

Re: [ovirt-users] MoM is failing!!!

[Dafna Ron]

Hi,

Can you please tell us what is the issue that you are actually facing?
:) it would be easier to debug an issue and not an error message that
can be cause by several things.

Also, can you provide the engine and the vdsm logs?

thank you,
Dafna

I am not sure what you mean by Minimal Centos 7 install. do you mean
it's hosted engine install?
can you please check if you can see the package by running yum search vdsm?

this happens on every node in the cluster. i tried the vdsm rpm from

the export domain so far can be accessed fine, already existing

set correctly uid/gid 36, nfsvers 3.


anyone got a hint for me ?

looks like this is what you are seeing.

For the records, I'm using thin provisioned disks here.
Do you mean an internal qemu task which is triggered to
extend a thin provisioned disk to the required size?

yes


This process shouldn't permanently pause the VM, right?

no



Or do you mean something else?

Re: [ovirt-users] 答复: Error after changing IP of Node (FQDN is still the same)

the host ip should also be in the certificates created when we install 
it and in the db.

re-installing the host would be easier and quicker.

Re: [ovirt-users] Missing Storage domain

even if the other hosts can see the domain, it doesn't mean that there

if you checked everything and you are positive that the host can see and 
connect to the domain please restart vdsm to see that there is no cache

Re: [ovirt-users] admin@internal login failure

[Dafna Ron]

the error you are looking for is in the vm log:

kvm: unhandled exit 8021
kvm_run returned -22

this seems to have been fixed in the past (if you do a google search you 
can find related bugs).

can you please make sure you are using the latest packages?

Thanks,
Dafna

Hey Everyone,

I am no longer able to log in with the internal admin account. I'm not
sure if this is related to me doing updates, or re-attaching the
engine to my ipa server.

For both webpage login and the ovirt shell I get the following
messaged in the enging.log file.

2014-07-11 11:01:16,685 WARN

I tried to do a engine-cleanup/engine-setup but that didn't help. I
don't want to lose all the data as this environment has been running
for a while now.

I then tried to remove the ipa domain and log in with the internal
admin user without success. Followed by re-adding my domain and adding
permissions to my ipa admin user which also did not work.

If anyone knows how to correct this that would be very helpful.

Thanks,

great!
this is an old bug that should have been fixed so I think you are using 
older versions of vdsm/libvirt and qemu.

writing (it's set to do that every 2GB I think).

during extend the vm pauses and resumes.

However, this action should not be noticeable by the vm user.

Does the vm pause and resumes or pauses completely? is it noticeable by 
the vm user?


Thanks,

Hi Morten,
My understanding of thin disks on a block domain is that vdsm traps
ENOSPC on the thin lv and uses the mailbox to get the SPM to extend
it.   See a presentation by Nir
http://www.ovirt.org/File:Storage-mailbox.odp
I thought I saw somewhere there were some changes/bugs around that for
allowing mixed data centers (both block and file domains). ...just
looked now and this bz looks relevant
https://bugzilla.redhat.com/show_bug.cgi?id=1083476


So maybe you could check the engine logs and spm logs for that flow
(sorry I can't tell you any specifics about what you should look for )

I just re-ran the test with adding a preallocated disk, and the problem did
_not_ appear. I tried a few times to write large files with dd, but the vm

Re: [ovirt-users] change disk size using a thin provision based template

[Dafna Ron]

I would assume that this is to avoid data corruption.
However it sounds like a good feature request (allow disk resize when 
creating a new vm from a template).

Can you please open it?

Hello,

I am making some tests and this time I want to reduce the disk size 
before create a new vm (in the new vm window )


test:
1) click on new VM
2) select template (centos6.5 , 6GB, 500GB HD , 2 cores)
3) resource allocation : select preallocated disk
4) change disk size  it is not possible !


Why I can not change disk size ?

I know it is based on template who had already  defined (500GB), but  
this template in fact  has only 4GB of actual size in thin 
provisioning allocation policy .


thanks

tamer

Re: [ovirt-users] Live migration failing

[Dafna Ron]

Actually, the best way to debug this would be to look at both des and 
src vdsm logs.

is this happening on all vm's or just one of them?
was this vm launched from an iso? is that iso still available?
are there any snapshots?
what are the vdsm, libvirt and qemu versions?

Thanks.

Its just very odd that I can snapshot any other VM except this one.

I just cloned a new VM from the last snapshot on this VM and it 
created without issue. I was also able to snapshot the new VM without 
a problem.

were these 23 snapshots created any way each time we fail to
create the snapshot or are these older snapshots which you
actually created before the failure?

at this point my main theory is that somewhere along the line you
had some sort of failure in your storage and from that time each
snapshot you create will fail.
if the snapshots are created during the failure can you please
delete the snapshots you do not need and try again

03 - vdsm (8 cpus, 32GB ram , 2TB HD)

My server 01 is the data domain and all new virtual machine is

how can I save each virtual machine on a desired vdsm server ?

server 02 - vdsm : 04 virtual machines running and hosted

server 03 - vdsm : 04 virtual machines running and hosted

server 02 - vdsm : 01 virtual machines running on this server
BUT hosted phisicaly on server 01

is it possible create one DATA DOMAIN for each VDSM host ? I

 hi, thanks for reply

 I am investigating what is and how thin virtualization
works

 Do you know if HADOOP is indicated to work under thin
environment ?
 On Hadoop I will put large workloads and this thin
virtualization utilizes more resources than exists (shareable
environment)
 that is,
 if I have a real physical necessity of 500gb for each hadoop
host and my Thin Virtualization has 2TB on NFS, I can have
only 4
virtual machines (500GB each), or less.

 For this case I believe clone virtual machine is the right
choice. But in my environment it takes 1h30m to build one
cloned
virtual machine.

if you plan to overcommit then go with thin. The drawback
is that
if you of course hit the physical limit the VMs will run
out of
space...
if you plan to allocate 500GB each, consume all of it,
never plan
to grow then go with the clone….yes, it's going to take
time to
write all that stuff. With thin you need to do the same
amount
of writes, but gradually over time while you're allocating
it it

hope it helps

Thanks,
michal




 Am I correct ?

Re: [ovirt-users] Ovirt snapshot failing on one VM

[Dafna Ron]

queries run on the system all the time but the only failure I 
encountered that was caused because of it was with live snapshots on a 
loaded setup in which vm running on the hsm would fail live snapshots if 
the system was loaded and the queries took a long time to come back.
However, since the error you have happens when the vm is down and only 
on that specific vm, I think it's most likely related to a failure 
somewhere in the chain.


Before committing or deleting any of the snapshots, is it possible for 
you to export the vm as is (with the snapshots) to an export domain? 
that way we know it's backed up before doing anything on the chain (and 
actually, this would be a much better way of backing up a vm rather than 
snapshots).


I don't really know what the problem in the chain is or when it 
happened, which is why I want to be cautious when continuing and delete 
of a snapshot would be better than committing it.


I can also suggest creating a new vm from any snapshot you think would 
be an important point in time for you - that case, even if there is a 
problem with the image you have a new vm with this image.


so to recap, lets try this:
1. restart vdsm and try to create a snapshot again
2. export the vm to an export domain without collapsing the snapshots
3. delete or commit the snapshots - if any fail please attach the logs. 
also, if you delete/commit, after each snapshot you can try to create a 
new snapshot to see if the issue is solved

steve,
I did not say that there is a limit. there is no limit and you can
take a 1000 snapshots if you like, I simply said that I think that
it would not be would a good practice to do so.


I'm not trying to be adversarial here, but this is contradictory; if 
there's 'no limit' but 'its not good practice' and we assume that we 
want our virtual infrastructure to run smoothly, then effectively 
there is a limit we just don't know what it is.


I also did not say that this is your current problem with the vm
so you are jumping to conclusions here.


I wasn't connecting the dots between # of snapshots, and the current 
issue, I have other VM's with the same amount of snapshots without 
this problem. No conclusion jumping going on. More interested in what 
the best practice is for VM's that accumulate snapshots over time.


There is a feature slated for 3.5 
http://www.ovirt.org/Features/Live_Merge which merges snapshots on a 
running VM, so I suppose in the long run I won't have a high snapshot 
count.


i simply explained how snapshots work which is that they are
created in a chain, if there is a problem at a single point in
time it would effect the rest of the snapshots below it.


Just for clarity, such a problem would affect the snapshots 'below it' 
means after the problematic snapshot? Example: Snapshot 1,2,3,4,5. #4 
has a consistency issue, snaps 1,2,3 should be ok? I can try 
incrementally rolling back snapshots if this is the case (after vdsm 
restart suggested).


Is there any way to do a consistency check? I can imagine scheduling a 
cronjob to run through a nightly check for consistency issues, then 
roll back to an earlier snapshot to circumvent the issue.


And that we query all images under the base Image so if you have a
lot of them it would take a long time for the results to come back.


That's good to know, is this query done on new snapshot creation only? 
So over time the more snapshots I have, new snapshots will take longer 
to complete?



as for your vm, since you fail to create a snapshot on only that
vm it means that there is a problem in the current vm and it's chain.

I can see when comparing the uuid's that the pool, domain, base

lets see if it's possibly a cache issue - can you please restart

I'll update when I have a chance to restart the services.

are you able to take an offline snapshot? (while the vm is down)
how many snapshots do you have on this vm?

were these 23 snapshots created any way each time we fail to create the 
snapshot or are these older snapshots which you actually created before 
the failure?


at this point my main theory is that somewhere along the line you had 
some sort of failure in your storage and from that time each snapshot 
you create will fail.
if the snapshots are created during the failure can you please delete 
the snapshots you do not need and try again?


There should not be a limit on how many snapshots you can have since 
it's only a link changing the image the vm should boot from.
Having said that, it's not ideal to have that many snapshots and can 
probably lead to unexpected results so I would not recommend having that 
many snapshots on a single vm :)


for example, my second theory would be that because we have so many 
snapshots we have some sort of race where part of the createVolume 
command expects some result from a query run before the create itself 
and because there are so many snapshots there is no such file on the 
volume because it's too far up the list.


can you also run: ls -l 
/rhev/data-center/9497ef2c-8368-4c92-8d61-7f318a90748f/95b9d922-4df7-4d3b-9bca-467e2fd9d573/images/466d9ae9-e46a-46f8-9f4b-964d8af0675b


lets see what images are listed under that vm.

btw, you know that your export domain is getting 
StorageDomainDoesNotExist in the vdsm log? is that domain in up state? 
can you try to deactivate the export domain?


Thanks,

Dafna

Ok.
so it's the qemu bug that Liron sent and I think there is some bug there
with the engine cache since we did not see the job failing in vdsm log.
hopefully there will be a qemu patch for centos soon...

can you migrate the disk off line?

Since LiveStorageMigration is a complicated and long task which divides
into 4 different jobs I asked for the log with the echo before the task
so we can easily follow the task from start to end.

however, I did grep for the task id in the logs you just attached and
there is nothing there.
I'm adding Elad to try and see if he can reproduce ERROR populated by

Thanks Liron,

well, unless the first vdsm log was cut we were not seeing any errors in
the vdsm log (engine was reporting an issue and vdsm did not show any
errors at all), after the engine restart we can see an error in the vdsm
log.
Maurice, was is possible that the vdsm log was cut? if not, there might
be a second bug with engine cache.

The Error we are seeing in the vdsm log now does indeed look like the
live snapshot issue in qemu :)

valid and important discussion indeed.
important enough I think that this should be raised in a separate thread

people may not be aware of a subject change).


Can you please send a new mail with a relevant headline raising this issue?

Ok.
so it's the qemu bug that Liron sent and I think there is some bug there
with the engine cache since we did not see the job failing in vdsm log.
hopefully there will be a qemu patch for centos soon...

Re: [ovirt-users] Snapshot removal

[Dafna Ron]

NFS is wipe_after_delete=true always.
so delete of snapshot will merge the data to upper level image + zero in 
on the data which is why this is taking a long time.

lets try to follow the action in both logs so we can debug it better,
can you do the following?

1. stop the vm and clean all snapshots.
2. add  to the engine and vdsm logs using echo (#echo '' 
/var/log/ovirt-engine/engine.log and #echo '' 
/var/log/vdsm/vdsm.log)
3. start the vm
4. try to live migrate the disk
5. attach the full engine and vdsm logs.

Re: [ovirt-users] HA question

[Dafna Ron]

you need to be more clear on your question it seems very general :)

do you mean, if the engine is down will power management still work?
If so, than the answer is no and with good reason... (lots of them 
actually).
starting from the simplest - if the host reboots and the engine is down, 
most users will not know how to restart the vms without the engine.
even if you do know how to start the vm's without the engine, once you 
restore the engine, there is a chance of split brain.

Re: [ovirt-users] ***UNCHECKED*** Re: HA question

[Dafna Ron]

the answer is no.
HA vm's are re-run by the engine in case of a failure so in case the 
engine is down no actions will be done on vms.

ok... Now I am starting to understand what's going on and if you look at
the vdsm log, the live snapshot succeeds and no other ERROR are
reported. I think it's related to the task management on engine side.

Can I ask you to run in the spm: vdsClient -s 0 getAllTasksInfo
If you have tasks we would have to stop and clear them (vdsClient -s 0
stopTask task ; vdsClient -s 0 clearTask task)
after you clear the tasks you will have to restart the engine

Also, what version of ovirt are you using? is it 3.4? because this was
suppose to be fixed...

here is the explanation from what I see in the logs:

you are sending a command to Live Migrate

]

The fist step is creating the snapshot:

Re: [ovirt-users] Error creating Disks

[Dafna Ron]

Thanks Liron,

well, unless the first vdsm log was cut we were not seeing any errors in 
the vdsm log (engine was reporting an issue and vdsm did not show any 
errors at all), after the engine restart we can see an error in the vdsm 
log.
Maurice, was is possible that the vdsm log was cut? if not, there might 
be a second bug with engine cache.


The Error we are seeing in the vdsm log now does indeed look like the 
live snapshot issue in qemu :)



Thanks,
Dafna

there's open bug on possibly the same issue - but let's verify that it's the 
same
https://bugzilla.redhat.com/show_bug.cgi?id=1009100

what OS are you running? if it's not centos, please try to upgrade libvirt and 
try again.

if it's urgent - as i see that you already stopped your vm during those tries, 
as a temporary solution you can stop the vm, move the disk while it's stopped 
(which won't be live storage migration) and than start it.

ok... Now I am starting to understand what's going on and if you look at
the vdsm log, the live snapshot succeeds and no other ERROR are
reported. I think it's related to the task management on engine side.

Can I ask you to run in the spm: vdsClient -s 0 getAllTasksInfo
If you have tasks we would have to stop and clear them (vdsClient -s 0
stopTask task ; vdsClient -s 0 clearTask task)
after you clear the tasks you will have to restart the engine

Also, what version of ovirt are you using? is it 3.4? because this was
suppose to be fixed...

here is the explanation from what I see in the logs:

you are sending a command to Live Migrate

Re: [ovirt-users] Error creating Disks

[Dafna Ron]

Since LiveStorageMigration is a complicated and long task which divides 
into 4 different jobs I asked for the log with the echo before the task 
so we can easily follow the task from start to end.


however, I did grep for the task id in the logs you just attached and 
there is nothing there.
I'm adding Elad to try and see if he can reproduce ERROR populated by 
engine because of cache.

Re: [ovirt-users] Error creating Disks

[Dafna Ron]

Hi Maurice,

are you getting any errors/alert about restarting the vm in the event 
log (in the webadmin).


I believe that you have a mismatch in the directory link between the db 
and vdsm which was created when you tried to live migrate and failed the 
fist time).


we can see in the vdsm log that createVolume (which is part of the live 
migration) is failing with this error:


OSError: [Errno 2] No such file or directory: 
'/rhev/data-center/a106ab81-9d5f-49c1-aeaf-832a137b708c/b7663d70-e658-41fa-b9f0-8da83c9eddce/images/348effd9-c5db-44fc-a9e5-67391647096b'


so it seems that the engine is pointing to a link that does not exist 
and we need to find on what storage the disk actually exists on and 
where the engine is pointing to.


you can look at the webadmin at the disk and see where it's suppose to 
be and than look in /rhev and see where the disk link is in vdsm (if you 
can see where the disk is actually is - physically in the storage, that 
would be good too).


Thanks,

Dafna

than you stop the vm and fail the AddDisk.


is there a chance you were having problems with your storage?

Re: [ovirt-users] Error creating Disks

[Dafna Ron]

ok.
so the vm was down and you deleted all the snapshots.
in the webadmin, when you select the disk you want to live migrate, is 
it the same storage reported in vdsm?


Thanks,

Hi Maurice,

are you getting any errors/alert about restarting the vm in the event
log (in the webadmin).

I believe that you have a mismatch in the directory link between the db
and vdsm which was created when you tried to live migrate and failed the
fist time).

we can see in the vdsm log that createVolume (which is part of the live
migration) is failing with this error:

OSError: [Errno 2] No such file or directory:
'/rhev/data-center/a106ab81-9d5f-49c1-aeaf-832a137b708c/b7663d70-e658-41fa-b9f0-8da83c9eddce/images/348effd9-c5db-44fc-a9e5-67391647096b'

so it seems that the engine is pointing to a link that does not exist
and we need to find on what storage the disk actually exists on and
where the engine is pointing to.

you can look at the webadmin at the disk and see where it's suppose to
be and than look in /rhev and see where the disk link is in vdsm (if you
can see where the disk is actually is - physically in the storage, that
would be good too).

Thanks,

Dafna

yeah, but is it the same error we see before in vdsm? :)
lets try to follow the action in both logs so we can debug it better, 
can you do the following?


1. stop the vm and clean all snapshots.
2. add  to the engine and vdsm logs using echo (#echo ''  
/var/log/ovirt-engine/engine.log and #echo ''  
/var/log/vdsm/vdsm.log)

3. start the vm
4. try to live migrate the disk
5. attach the full engine and vdsm logs.

Thanks,

Dafna

browsing the ovirt admin page I see 2 occurrences of ovirt version:

I would like to understand what means all these versions, the same

all my doubts together :
What means datacenter in version 3.3(or lower version) when ovirt is 
3.4  ?

what means cluster in version 3.3 when ovirt is 3.4?
what means change the compatibility version for datacenter?
what means change the compatibility version for cluster?

I have this message :

Host is Storage Pool Manager and is in Non Responsive state.
- If power management is configured, engine will try to fence
the host automatically.
- Otherwise, either bring the node back up, or release the SPM
resource.
To do so, verify that the node is really down by right
clicking on the host and confirm that the node was shutdown
manually.



are there any running vm's reported?


No there is no VM running on this host



Try to press the confirm host has been rebooted button
and than
see if you can put the host in maintenance.

If that fails, select the host, in the general tab you
will get
the re-install link.



I am running ovirt 3.4.0-1. I down't know where is the
re-install link but I can't see it.

try to re-install, when install fails the host should change
status to failed installation.

Re: [ovirt-users] Re-add a node

[Dafna Ron]

I think there might be a chance it's related to issues we were seeing 
with engine cache.


James, would you mind testing that? restart of ovirt-engine process 
should clear the cache.
once you restart, log in to the webadmin and if the host is still spm 
and none responsive, can you try confirm host reboot again?


If that still fails, can you please attach the engine log?

Thanks.
Dafna

For extending the VM disk, as Dafna mentioned,  you should use the ovirt-engine

If you'd like to extend your OS disk, there is a nice guide for that. it's not 
an official guide AFAIK, but it works :)

Everything was good, the vm can run on any host, but the live

I can make live snapshot, but it doesn't show on the panel.


So:

- the live migration doesn't work.

Can anyone help me?

Re: [Users] The purpose of Wipe on delete ?

[Dafna Ron]

1. you cannot use this option for nfs based storage since we zero the 
files any way when we delete the disk (the only way to actually delete 
it in nfs).
2. configuration on the storage side is the administrator decision... 
they can choose not to use this option and use a different method on 
storage side.

wipe = writing zero's on the space allocated to that disk to make sure any data

so it's  a security vs speed decision on using this option - since we zeroing 
the disk to make sure any information once written will be overwritten,
a delete of a large disk can take a while.

I think this may be not really useful, zeroing files on modern file systems 
can't grant any kind of security improvement.
According to shred man page:

CAUTION: Note that shred relies on a very important assumption: that 
the file system overwrites data in place.  This is the traditional way to
do things, but many modern file system designs  do  not
satisfy this assumption.  The following are examples of file systems on 
which shred is not effective, or is not guaranteed to be effective in
all file system modes:

* log-structured or journaled file systems, such as those supplied with 
AIX and Solaris (and JFS, ReiserFS, XFS, Ext3, etc.)

* file systems that write redundant data and carry on even if some 
writes fail, such as RAID-based file systems

* file systems that make snapshots, such as Network Appliance's NFS 
server

* file systems that cache in temporary locations, such as NFS version 3 
clients

* compressed file systems

In the case of ext3 file systems, the above disclaimer applies (and 
shred is thus of limited effectiveness) only in data=journal mode, which
journals file data in addition to just metadata.  In both
the data=ordered (default) and data=writeback modes, shred works as 
usual.  Ext3 journaling modes can be changed by adding the data=something
option to the mount options for a particular file system
in the /etc/fstab file, as documented in the mount man page (man mount).

In addition, file system backups and remote mirrors may contain copies 
of the file that cannot be removed, and that will allow a shredded file

Re: [Users] The purpose of Wipe on delete ?

[Dafna Ron]

wipe = writing zero's on the space allocated to that disk to make sure 
any data once written will be deleted permanently.


so it's  a security vs speed decision on using this option - since we 
zeroing the disk to make sure any information once written will be 
overwritten, a delete of a large disk can take a while.

Re: [Users] How do you move an host with local-storage into regular Data Center?

[Dafna Ron]

you did not remove the storage before moving the host.
If you select the force remove DC option it should clean all object 
under that DC (just make sure you are selecting the one you want to 
remove ;))

Hi all,
I need your help to clean up my DataCenter.

I'm new to this wonderful product so I'm exploring to understand what's offered.
I'm talking about 3.4.0beta3 (Centos 6.5).

In the beginning it was a normal system with two hosts, an iSCSI
storage, and the engine installed as a regular KVM guest on another
host (external to the oVirt setup).
So far so good.

Then I selected one of the two hosts, put it in maintenance mode,
clicked on Configure Local Storage, accepted the defaults for Data
Center, Cluster and Storage, put in an appropriate path to local
storage...
Now I have another DC (hostname-Local), another Cluster
(hostname-Local) and another SD (hostname-Local). This host has been
migrated from the original Cluster and it is now in the
hostname-Local Cluster. Nothing to regret, I was expecting something
like that.

Obviously I have now a single host in my main DC and so I'm unable
to do migration of VMs and so on.

After some tests I decide to go back to the original situation.
I put again the host in maintenance mode, Edit, select the correct
DC and the host is now back in his place.

Now I try to remove the spurious DC to clean-up the situation but the
result is an error popup:
Error while executing action: Cannot remove Data Center. There is no
active Host in the Data Center.

OK, I move again the host in. But now when I select the DC the
Remove button is obviously greyed out.

Well, for the moment I'm happy to move again the host into the regular
DC to gain full functionality of my cluster but I would like to clean
my setup removing the other, useless, DC.
Does anyone know how to get out from this?
I'm probably missing something obvious but here I'm stuck.

TIA,
Giorgio.

Re: [Users] Disk Migration

[Dafna Ron]

I don't think that you can configure interface for disk migration.
Disk migration is actually copy of information from the original disk to 
a new disk created on a new domain + delete of the original disk once 
that is done.
it's not actually a migration and so I am not sure you can actually 
configure an interface for that.
adding ofer - perhpas he has a solution or it's possible and I am not 
aware of it.

You can use the same iso's on different DC's and multiple vm's can read

Re: [Users] moving an unplugged/offline disk on a running vm creates snapshots

sounds like this issue only libvirt is not blocking the command.

Re: [Users] [BUG] wrong template shown for vm

[Dafna Ron]

in 3.3 this was the correct behavior if the vm is not linked to the 
template (so if it was a clone and not thin copy it would have Blank 
for template)


in 3.4 there is a new feature which should show the vm name under the 
General tab even if it was created as a clone.

so this should have actually been solved in 3.4

https://bugzilla.redhat.com/show_bug.cgi?id=1068679

when you create a vm from an imported template (from export doomain)
the template info for the vm shows that it is based on the blank template.

I can reproduce this on ovirt 3.3.3-2.el6

it would be cool if someone could try to reproduce this on 3.4 and
on fedora.

Re: [Users] Unable to Remove Template, if VM exists.

[Dafna Ron]

As long as the vm is linked to the template (which means you created the 
vm as a thin provision copy) you cannot delete the template.

what you can do to work around this is:
1. export the vm and template to an export domain
2. delete the vm and template from the source setup only
3. try to import the vm as clone

other way is:
1. create a template from the vm
2. create a new vm from the template (make sure to create a clone and 
not a thin copy this time :))

Re: [Users] Live migration of VM's occasionally fails

Thanks Steve!
I am still perplexed how come one out of two identical vm's would fail 
migration... logic states that they should both fail.

I then deleted a failed posix domain on another gluster volume with

migrated successfully. Perhaps gluster isn't passing storage errors up 
properly for non-dependent volumes. Anyways this is solved for now, 
just wanted this here for posterity.

if so how many snapshots does the vm have.
I think that there are newer packages of vdsm, libvirt and qemu -
can you try to update

Re: [Users] Live migration of VM's occasionally fails

[Dafna Ron]

mmm... that is very interesting...
both vm's are identical? are they server or desktops type? created as 
thin copy or clone? what storage type are you using? did you happen to 
have an open monitor on the vm that failed migration?
I wonder if it can be sanlock lock on the source template but I can only 
see this bug happening if the vm's are linked to the template

can you look at the sanlock log and see if there are any warning or errors?

All logs are in debug so I don't think we can get anything more from it 
but I am adding Meital and Omer to this mail to help debug this - 
perhaps they can think of something that can cause that from the trace.


This case is really interesting... sorry, probably not what you want to 
hear...  thanks for helping with this :)

Are there any increased logging levels that might help determine what

Re: [Users] Stuck Migration

[Dafna Ron]

I think there might be a command to clear the cache.
Omer, is there a command to clear the engine cache aside from restart?

That worked. Was there any other way to do it without a restart?

 I have a vm that is shut down and is somehow stuck in a migration
 state. Im running version 3.3.3-2 on this setup. The vm disk is
 activated and cannot be deactivated, and the vm is shut down and
 cannot be started. When I try to start the vm it tells me that it
 cannot be started because it is in the process of migrating

Re: [Users] Disk Images

[Dafna Ron]

There was a talk in the past to allow edit of the disk as its own entity 
it but I think that some of the disk params are vm dependent so editing 
them for disk only are a problem.

Ayal, do you remember why editing the disk on it's own was not implemented?

On 02/13/2014 07:33 AM, andreas.ew...@cbc.de wrote:

Yes, I know! Why is there this restriction? I have the following scenario: I have a 
recover vm with one bootable disk attached. Now I want to repair some broken 
configs from another vm’s boot disk. First I unattach the device from the broken vm. If I 
forget to remove the bootable flag, then I have to attach the disk again to the broken 
vm. I remove the bootable flag and attach the disk to my „recover vm“.  This is quite a 
long way round.
This could be a feature request, right?

You can just put plain password, it should work...

If you want to encrypt use:

echo -n 'PASSWORD' | openssl pkeyutl -encrypt -certin -inkey 
/etc/pki/ovirt-engine/certs/engine.cer  | openssl enc -a | tr -d '\n'

But Dafna, isn't there a way at UI to re-specify password, so it be encrypted 
by the application?


the problem is that the storage already exists but non-operational and 
we cannot edit a storage in any status other than active.
so if the password changed during a storage issue, the storage cannot 
recover to active state if the password had changed and the luns are not 
visible on the storage and we also cannot edit the password for the 
domain...

In my opinion when I first defined the ISCSI domain and input a wrong
password there was something not correctly managed when I then used
the correct one.
In fact in my opinion it seems there is no correspondence between
storage_domains table and storage_server_connections table.

If I take a glusterfs domain named gv01 I see this:

engine=# select * from storage_server_connections where id=(select
storage from storage_domains where storage_name='gv01');

Instead for this ISCSI domain named OV01

engine=# select * from storage_server_connections where id=(select

Re: [Users] Will this two node concept scale and work?

[Dafna Ron]

Hello List,

my aim is to host multiple VMs which are redundant and are high 
available. It should also scale well.


I'm assuming you are talking about HA cluster since redundancy vm and HA 
vms are a contradiction :)


I think usually people just buy a fat iSCSI Storage and attach this. 
In my case it should scale well from very small nodes to big ones.
Therefore an iSCSI Target will bring a lot of overhead (10GBit Links 
and two Paths, and really i should have a 2nd Hot Standby SAN, too). 
This makes scalability very hard.


This post is also not meant to be a iscsi discussion.

Since oVirt does not support DRBD out of the box i came up with my own 
concept:


check out posix storage domain.
If it supports gluster you might be able to use it for DRBD.



http://oi62.tinypic.com/2550xg5.jpg

As far as i can tell i have the following advantages:

- i can start with two simple cheap nodes
- i could add more disks to my nodes. Maybe even a SSD as a dedicated 
drbd resource.
- i can connect the two nodes directly to each other with bonding or 
infiniband. i dont need a switch or something between it.


Downside:
---
- i always need two nodes (as a couple)

Will this setup work for me. So far i think i will be quite happy with it.
Since the DRBD Resources are shared in dual primary mode i am not sure 
if ovirt can handle it. It is not allowed to write to a vm disk at the 
same time.


not true that you cannot write to the same vm disk at the same time - 
you have a shared disk option




The Concept of Linbit 
(http://www.linbit.com/en/company/news/333-high-available-virtualization-at-a-most-reasonable-price) 
seems to much of an overhead with the iSCSI Layer and pacemaker setup. 
Its just too much for such a simple task.


Please tell me that this concept is great and will work and scale well.
Otherwise i am also thankful for any hints or critical ideas.


Thanks a lot,
Mario

Dafna, I saw you've already opened a bug on that:

just proves I'm getting senile :)

Maor I am not saying that we are not doing a live snapshot :) I am
saying that we need a print in the log that states live snapshot command
was called i.e: Print in the log: LiveSnapshotCommand - this can call
to the rest of snapshotVDSCreateCommand.

Maor,

If snapshotVDSCommand is for live snapshot, what is the offline create
snapshot command?

It is the CreateSnapshotVdsCommand which calls createVolume in VDSM

but we need to be able to know that a live snapshot was sent and not an
offline snapshot.

Yes, at the logs we can see the all process :

First a request to create a snapshot (new volume) sent to VDSM:

Elad, somewhere in this flow we need to know that the snapshot was taken
on a running vm :) this seems like a bug to me.

we did not say that live snapshot did not succeed :)  we said that the
vm is paused and restarted - which is something that should not happen
for live snapshot (or at least never did before).

It's not sure that the restart is related to the live snapshot. but that
should be observed in the libvirt/vdsm logs.

yes, I am sure because the user is reporting it and the logs show it...

as I wrote before, we know that vdsm is reporting the vm as paused, that
is because libvirt is reporting the vm as paused and I think that its
happening because libvirt is not doing a live snapshot and so pauses the
vm while taking the snapshot.

That sounds logic to me, it's need to be checked with libvirt, if that
kind of behaviour could happen.

Elad, can you please try to reproduce and open a bug to libvirt?

From the engine logs it seems that indeed live snapshot is called
(The

This is done right after the snapshot has been created in the VM and it
signals the qemu process to start using the new volume created.

When live snapshot does not succeed we should see in the log something
like Wasn't able to live snapshot due to error:..., but it does not
appear so it seems that this worked out fine.

At some point I can see in the logs that VDSM reports to the engine
that
the VM is paused.

Re: [Users] oVirt 3.3.3 RC EL6 Live Snapshot

[Dafna Ron]

No, the bug is about libvirt pausing the vm's for live snapshot

I am not sure about your question on clock skew... we have to take a lot 
of snapshot to surpass the 5 minutes skew though :)

Just for clarity on that bug report; are you suggesting that the guest 
must go into a paused state to take a snapshot and that the admin 
shouldn't be aware of this state?


Although not horribly concerning for most tasks, wouldn't this lead to 
a 10 second clock skew every time there is a snapshot? Or does the 
guest sync from host hw clock on resume?

Thanks Steve.

from the logs I can see that the create snapshot succeeds and that
the vm is resumed.
the vm moves to pause as part of libvirt flows:

2014-02-02 14:41:20.872+: 5843: debug :

2014-02-02 14:41:30.031+: 5843: debug :
qemuProcessHandleResume:776 : Transitioned guest snapshot-test out
of paused into resumed state

There are bugs here but I am not sure yet if this is libvirt
regression or engine.

I'm adding Elad and Maor since in engine logs I can't see anything
calling for live snapshot (only for snapshot) - Maor, shouldn't
live snapshot command be logged somewhere in the logs?
Is it possible that engine is calling to create snapshot and not
create live snapshot which is why the vm pauses?

Elad, if engine is not logging live snapshot anywhere I would open
a bug for engine (to print that in the logs).
Also, there is a bug in vdsm log for sdc where the below is logged
as ERROR and not INFO:

Thread-23::ERROR::2014-02-02
09:51:19,497::sdc::137::Storage.StorageDomainCache::(_findDomain)

looking for domain a52938f7-2cf4-4771-acb2-0c78d14999e5

If the engine was sending live snapshot or if there is no
difference in the two commands in engine side than I would open a
bug for libvirt for pausing the vm during live snapshot.

Re: [Users] oVirt 3.3.3 RC EL6 Live Snapshot

[Dafna Ron]

Maor,

If snapshotVDSCommand is for live snapshot, what is the offline create 
snapshot command?


we did not say that live snapshot did not succeed :)  we said that the 
vm is paused and restarted - which is something that should not happen 
for live snapshot (or at least never did before).
as I wrote before, we know that vdsm is reporting the vm as paused, that 
is because libvirt is reporting the vm as paused and I think that its 
happening because libvirt is not doing a live snapshot and so pauses the 
vm while taking the snapshot.

 From the engine logs it seems that indeed live snapshot is called (The
command is snapshotVDSCommand see [1]).
This is done right after the snapshot has been created in the VM and it
signals the qemu process to start using the new volume created.

When live snapshot does not succeed we should see in the log something
like Wasn't able to live snapshot due to error:..., but it does not
appear so it seems that this worked out fine.

At some point I can see in the logs that VDSM reports to the engine that
the VM is paused.

Thanks Steve.

from the logs I can see that the create snapshot succeeds and that the
vm is resumed.
the vm moves to pause as part of libvirt flows:

2014-02-02 14:41:20.872+: 5843: debug : qemuProcessHandleStop:728 :
Transitioned guest snapshot-test to paused state
2014-02-02 14:41:30.031+: 5843: debug : qemuProcessHandleResume:776
: Transitioned guest snapshot-test out of paused into resumed state

There are bugs here but I am not sure yet if this is libvirt regression
or engine.

I'm adding Elad and Maor since in engine logs I can't see anything
calling for live snapshot (only for snapshot) - Maor, shouldn't live
snapshot command be logged somewhere in the logs?
Is it possible that engine is calling to create snapshot and not create
live snapshot which is why the vm pauses?

Elad, if engine is not logging live snapshot anywhere I would open a bug
for engine (to print that in the logs).
Also, there is a bug in vdsm log for sdc where the below is logged as
ERROR and not INFO:

Thread-23::ERROR::2014-02-02
09:51:19,497::sdc::137::Storage.StorageDomainCache::(_findDomain)
looking for unfetched domain a52938f7-2cf4-4771-acb2-0c78d14999e5
Thread-23::ERROR::2014-02-02
09:51:19,497::sdc::154::Storage.StorageDomainCache::(_findUnfetchedDomain)
looking for domain a52938f7-2cf4-4771-acb2-0c78d14999e5

If the engine was sending live snapshot or if there is no difference in
the two commands in engine side than I would open a bug for libvirt for
pausing the vm during live snapshot.
