  Thanks for the response.  Is the master release accessible via a repo.?
 
  from your question I understand that you are currently using ovirt 3.2.1
  rather
  than master [to answer Itamar's question from the previous e-mail], and
  that explains
  the slowness of the portals on IE8 that you are experiencing.
 
  Please note that on oVirt master, the performance improvement patches for
  IE8 affect
  only the user portal; unfortunately, the admin portal still suffers from
  performance
  problems on IE8.
 
  with regards to the master release accessibility: I am not sure if we have
  a master
  release; you can build oVirt-engine directly from the code-repo by
  following the
  instructions in the following wiki-page:
  http://www.ovirt.org/Build_and_Install_Engine_RPM
 
  @Itamar/others: do we have some kind of a nightly/weekly/occasionally
  repository of
  ovirt builds/rpms? the IE8 performance patches were introduced to oVirt
  master on March 1
  (almost 2 months ago), so anything rebased from ovirt master at that point
  in time or
  afterwards would be helpful.
 
 yes, there is a nightly build (it changes every night...)
 http://www.ovirt.org/Yum_repo_file
 
 set nightly to enabled (maybe need to disable the others).
 that's for fedora - I think we have one for .el6 now with 3.2.1
 supporting it.
 eyal/moran?


for master branch yes:

current nightly builds are done for fedora 17/18: 
http://resources.ovirt.org/releases/nightly/rpm/Fedora/{17|18}
and for EL6: http://resources.ovirt.org/releases/nightly/rpm/EL/6/


for 3.2.1, we don't have nightly builds, just stable release:
 
http://resources.ovirt.org/releases/stable/rpm/EL/6/noarch/

 
 
  I've been using Fedora 18.  Is usb pass-through not supported for Windows
  clients?
 
  as Itamar mentioned below, spice-devel mailing-list members (CC'd) should
  be able to answer
  this question.

  for the IE8 - some improvements went to master for IE8 performance, but
  i don't think they are in ovirt 3.2.1 (einav?).
 
  that's right: the recent IE8 improvements are not included in ovirt
  3.2.1,
  they are only in master.

is the vm preallocated or thin provision disk type?


This VM has 3 disks :
- first disk to host the windows system : Thin provision
- second disk to store some data : Preallocated
- third disk to store some more data : Thin provision

I'm realizing that amongst the 15 VMs, only this one and another one
that is stopped are using preallocated disks.
I'm regularly migrating some VMs (and stopping and starting and playing
with them) with no issue, and they all are using thin provisioned
disks!

Could this be a common factor of the problem?



also, can you please attach engine, vdsm, libvirt and the vm's qemu
logs?


Relevant logs :



Ok, I'm in the process of collecting the logs and posting them in a
useable manner.

More to come.


Ok, once again, I ran a test and observed the relevant logs.
I tried to isolate the time frames, but it may be long for vdsm.log

Here they are :
* /var/log/libvirt/qemu/serv-chk-adm3.log
http://pastebin.com/JVKMSmxD
* /var/log/libvirtd.log
http://pastebin.com/sWGDCqNh
* /var/log/vdsm/vdsm.log (the BIG one)
http://pastebin.com/bevTEhym

What I can add to help you help me, is that :
- I saw that all my VM appear as tainted. I did not know what that meant
(but RTFMed since), and this does not appear to disturb the other VMs
- Many VMs including the problematic one have been imported from
ovirt-v2v with now such issue.
- This particular VM was also imported, but the starting point was a
vmdk or ova single file.
- Two additionnal data disks were added
- As I said, this is the only running VM stored as pre allocated.

Regards,



One suggestion : I see no obvious errors in the log files. Could this
paused state happen due to a VM's kernel panic?



is this still relevant?


It is!
Further investigations from my colleague shown the following facts :
- This VM has 3 disks. Only one of those disks is responsible for the 
problem
- In this disk, my coworker has found only 3 files (database files) that 
he can do nothing with without leading to the freeze.

- He tried to cat them into /dev/null, and this is leading to the freeze
- He tried to copy them into another disk - freeze!

We see absolutely no evidence of a kernel panic.
Rather, this seems to be related to a network bottleneck between the 
node and the iSCSI SAN, leading to oVirt unable to sustain a sufficent 
bandwidth and freezing the VM.


Since then, we moved to another solution, but for the sake of opensource 
debugging, we did kept the faulty VM for your eyes only :)

  some questions
 
  can we use ootb qemu-guest-agent with ovirt 3.2.1 if we have for
  example a CentOS 6 guest (with qemu-guest-agent-0.12.1.2-2.355)?
  Does oVirt create a virtio-serial port to communicate with libvit and
  does it use libvirt with any options to quiesce  fs on guest?
 
 iirc, it should work - testing/feedback would be welcome.

I believe vdsm does not create the virtio-serial port when starting the VM, so 
you'd have to modify this behaviour with hooks [1].
Once you do that, whenever you create a live snapshot vdsm will notify libvirt 
to quiesce first.
Note that afaik, quiesce in qemu-ga is only supported for Linux guests.  VSS 
quiesce support patches have been submitted, but I'm not sure what the status 
is there yet. 

[1] Hooks preso: http://www.ovirt.org/File:OVirt-hooks-netapp-jan2013.odp

 
 
  Can one use as an alternative the command fsfreeze in CentOS 6.4 guest
  (even if in tech preview) as in :
  https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Technical_Notes/storage.html

Re: [Users] oVirt storage is down and doesn't come up

2013-04-21 Thread Yeela Kaplan
It looks to me like the master it is looking for is no longer there, I'm not 
sure what happened.
What you can try to do to get your storage back up is to create a new storage 
domain(it won't be able to attach since your pool is not connected to the host).
Then right click on the new SD and choose to re-initialize data center.
It will try to reconstruct your master SD.
also, just so that I have more information about the state of your system, 
please attach the result of: 'ls -ltr /rhev/data-center/'.
If you want to make this more interactive, you can connect to IRC.
