Hi All,
I have a multi-VM setup, where I have ovirt engine on one VM and 
VDSM host on another.
Discovering the host from the engine puts the host in Unassigned

When i select setupNetworks and drag-drop the ovirtmgmt to setup over 
eth0, i see the below error in VDSM & host goes to non-operataional

If you just run vdsm to test the functions not related to network, you 
could just disable the libvirt default network before you start up the 
vdsm service.

Re: [Users] latest vdsm cannot read ib device speeds causing storage attach fail

2013-01-24 Thread Mark Wu 

Great work!
The default action for SIGCHLD is ignore, so there's no problems 
reported before a signal handler is installed by zombie reaper.
But I still have one problem: the python multiprocessing.manager code 
is running a new thread and according to the implementation of python's 
signal, only the main thread can receive the signal.

So how is the signal delivered to the server thread?

so the second one raise error.

I patched python source managers.py to retry recv() after EINTR,
supervdsm works well and the issue gone.
Even declared in python doc that:"only the main thread can set a
new signal handler, and the main thread will be the only one to
receive signals (this is enforced by the Python signal
<http://docs.python.org/2/library/signal.html#module-signal> module,
even if the underlying thread implementation supports sending signals
to individual threads). "(http://docs.python.org/2/library/signal.html)
But according to my test script bellow, the child process forker
event if it is not the main thread, also got SIGCHILD, Will it be a
python BUG or feature?


Thanks for sharing your test code. After testing your script and  
looking into the python signal module,
I found that the signal could be received by any thread!  Python 
installs a signal handler wrapper for
all user defined signal handler. The wrapper  just adds the actual 
handler to the queue of pending
calls,  and the main thread check the pending calls and run the actual 
hander before executing the next instruction.
So, the signal interruption can happens to any thread and therefore the 
wrapper could run in any thread.
But the user-defined handler only runs in the main thread. And if the 
signal occurs in non main thread, the main
thread will not be interrupted  and the signal will only be handled 
when the main thread finishes the current instruction.


Please correct me if I am wrong.



I agree with Mark maybe we should use synchronised way to deal
with child process instead of signal handler.
import threading
import signal
import time
import os
from multiprocessing import Process,Pipe
def _zombieReaper(signum, frame):
 print 'sigchild!!!'

def child():
 time.sleep(5)
def sleepThread():
 proc = Process(target=child)
 proc.start()
 pip,pop = Pipe()
 pip.recv()<--This line will get IOError.EINTR by SIGCHLD
def main():
 signal.signal(signal.SIGCHLD, _zombieReaper)
 servThread = threading.Thread(target = sleepThread)
 servThread.setDaemon(True)
 servThread.start()
 time.sleep(30)
if __name__ == '__main__':
     main()

Yes, it could break live migration.  But we could use 
conntrack-tools(conntrack or conntrackd)
to sync the ip conntrack entries related to that VM's ip address before 
resume the VM on dest host.

Just a preliminary idea, not verified yet.



how would floating IP work? wouldn't you need to map it 1:1 with the
NAT'd IP?
Yes, it should have a 1:1 mapping between external ip address and the

Hello,

Has somebody experience with Dell MD3600i and oVirt 3.2.1?

Both switch are in stack mode and storage is connect with four 10Gb 
ports in same subnet (is better to use it without stack as two subnet?)


So, where is problem...I can create iSCSI storage domain, everything 
seems to be OK but when I want to add next host they cannot access 
this iSCSI target (in storage management tools is already added to 
host group)


And during this process I can see only on host console IO error, 
buffer error and kernel BUG: soft lockup -- CPU stuck etc...



Could you please paste the log messages related to the errors above ?


Exists recommended way how involved iSCSI?

Re: [Users] host goes to non-operational because interface down message

2013-04-11 Thread Mark Wu 

Gianluca,

Thanks for your so detailed report.  But unfortunately I can't find any 
clue related to
this network interface status problem.  Sorry for that. Maybe other guy 
can add more comments.


At this moment, I suspect  the link of em1.311 and probably its 
underlying interface em1 went down occasionally and came up in a
short time.  Is it possible?   You could check the system log 
'/var/log/messages' to find related  messages.




Thanks for your input Mark.
At the moment all is well again with the host; anyway I'm going to
give a long explanation of what I did below and so possible reasons
for that situation.
There is also feed for developers answers in that ...

I cannot connect at the moment to the host to cut and paste in text
but I have access to java console and here is a screenshot containing
the line you requested (captured now that all is ok and host up and
runnign with two VMs):

https://docs.google.com/file/d/0BwoPbcrMv8mvdmdIMUxTRVRVUzg/edit?usp=sharing

Which fields are expected to be indicators of problems, as I had yesterday?

You can check the 'state' filed in each interface.



The story:

oVirt is 3.2.1
- create a datacenter of type local_on_host
- create a cluster
- the ovirtmgmt is intended to be vlan tagged but I forget it... damn...
- I add a host (f18) where I prepared network configured with vlan

ifcfg-em1
ifcfg-em1.311

- the host deploy completes successfully --> here in my opinion a
possible bug because ovirtmgmt is not tagged?
- host reboots and apparently all is ok
- I can create local_on_host SD and ISO
- all is up and running without any VM yet

The host is a blade inside an IMS enclosure and I discover that
actually I can configure the storage assigned (second disk of the
blade) as FC and that there is also multipath for this kind of servers
(see the other thread of mine).

The optimal would be to deactivate all and redefine the DC as
Fibrechannel type but it seems not so easy

I probably make an error at this point because instead of directly
putting host into maintenance I follow these steps in the gui:
- expand my DC at the left
- expand STORAGE of that DC on the left
- select my storage domain (LSTORAGE) on the left

On the right pane  I select the line of LSTORAGE and in the bottom
pane I select the "datacenter" label where I then select the line of
my DC.
I choose "maintenance"

--> what is it supposed I have done this way?
Put storage domain in maintenance or DC or what?

Is it supposed to be a correct operation what I've done if the DC is
Up and this is the only SD I have?
Or would it be correct to receive an error from the system?

Because I don't receive any error and I see the SD down and host that
keeps staying with the status "Preparing to maintenance"

I don't remember correctly my steps here, possibly restart of host
that is recognized then as unassigned.
After that I cannot "force remove" the DC and I cannot remove the
cluster or host because it is not in maintenance.

After I also reboot the engine service and restart  the host, it comes
up normally with all the DC with the old config.
At this point I can put host in maintenance and force remove the DC
I create a new DC with same name but with type FC and ovirtmgmt as
vlan tagged and I see that the existing cluster is still present, so I
attach it to the new DC (that has the same name as before).
I also find that there is my host that seems to automatically be in
this cluster.

But at this point when I activate it, it comes up but after a few
minutes I get the message I posted at the beginning
In host details, its network interfaces keep down.
Tried different restarts of host.
So I decide to put host into maintenance and select into the gui to
"reinstall" it.
After this all goes well again..

Sorry for the long story

Gianluca

Since LUN's are mapped to all the machines in the cluster, I guess it is not on

What does  "grep -v ^#  /etc/libvirt/qemu-sanlock.conf"  say?

Have you tried `/usr/lib/systemd/systemd-vdsmd reconfigure` ?

it's not a physical host?


I guess so.  Please the cpuModel:

  new host:
cpuModel = QEMU Virtual CPU version (cpu64-rhel6)
  old host:
cpuModel = Intel(Fake) CPU

Re: [Users] Issue setting IP information for Non-VM networks

A few weeks back I started a discussion about my issues with

The bug is here, https://bugzilla.redhat.com/show_bug.cgi?id=834205.

I've since upgrade to latest ovirt / vdsm and while the issue seems to
be resolved it's now failing in a different way.  Looking at the logs
, it looks like the correct parameters are being passed to vdsm but
the ifcfg-eth* is still left with no IPADDR or NETMASK values.

Attached are logs from when Assigning a Static IP to both eth0 /

After performing the change in the web interface, this is ifcfg-eth1
(missing IPADDR and NETMASK)
# cat ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
HWADDR=00:25:90:4c:91:bf
NM_CONTROLLED=no

I can reproduce this problem with vdsm-4.10.0-6.fc17.x86_64.
It turns out the fix for bz834205 is not backported to oVirt 3.1 branch.
Igor, do you think it should be backported?

I've also run into an issue where in the web interface, the ovirtmgmt
network always reverts back to DHCP as the boot protocol.  The ifcfg
on node will reflect the correct setting after I change to static, but
if I go to re-edit the entry, it's back on DHCP.

I hit this problem before, and filed a bug for it:
https://bugzilla.redhat.com/show_bug.cgi?id=838816

Can someone help please?

It seems it's related http://gerrit.ovirt.org/#/c/4720/.   The 
unnecessary nfs related rpm/commands including rpc-bind were removed 
from ovirt-node. But the service nfs-lock requires rpc-bind, so it

can't start.  I guess so.  Michael,  is it?   Thanks!

On 09/19/2012 11:25 PM, Christopher Maestas wrote:

When you add a fc17 node and look at it, it seems to add:
* ovirtmgmt bridge
* p2p1 interface
* and bond0-bond3.

Where does the bonding information get stored? It doesn't seem to be 
in /etc/sysconfig/network-scripts?



The bonding devices are created dynamically when vdsmd starts.
The reason I ask, is I have two nodes one of which has the bonding 
interfaces up and the other which doesn't. The one that doesn't have 
the bonding interfaces up is failing to be added to the ovirt node list.


I am not sure how the failure of adding host is related to bonding 
interfaces.  You could check the log
/tmp/vds_bootstrap.xx.log and /tmp/vds_installer.xx.log during 
node installation.

As you can see, I have tried many cpu type for launching this guest 
hypervisor, but none of them is accepted by the hypervisor. Plus, I've 
modified each time the family type in the cluster tab, but it is the 
same.

On the hist:

Thanks for your help



What does the command 'qemu-kvm -cpu ?' give ?   Could you please try

I've got error too during definition of nested kvm.

When i run qemu-kvm cpu ? i get: Unable to find x86 CPU definition. do 
you know why? what does this command show?


how do i add your configuration suggestion to my guest cpu?
Here's the output of  "qemu-kvm -cpu ?". It shows us which cpu models 
qemu can emulate.

x86   Opteron_G3
x86   Opteron_G2
x86   Opteron_G1
x86  Nehalem
x86   Penryn
x86   Conroe
x86   [n270]
x86 [athlon]
x86   [pentium3]
x86   [pentium2]
x86[pentium]
x86[486]
x86[coreduo]
x86  [kvm32]
x86 [qemu32]
x86  [kvm64]
x86   [core2duo]
x86 [phenom]
x86 [qemu64]

You can use 'virsh edit' or edit the xml configuration file of the vm to 
specify the cpu model. Just put the cpu definition into the root 
(domain) tag.



core2duo



After that, you should be able to see it in the output of 'virsh 
dumpxml'.  And the cpuinfo from guest should read like this:


#cat /proc/cpuinfo
processor: 0
vendor_id: GenuineIntel
cpu family: 6
model: 15
model name: Intel(R) Core(TM)2 Duo CPU T7700  @ 2.40GHz

Is there any error related in /var/vdsm/vdsm.log ?

Did you try to manually discover and login the iscsi target by the 
following command?


iscsiadm --mode discoverydb --type sendtargets --portal 192.168.122.1 
--discover   // replace the portal address with your iscsi server's ip

When I run "tail -f  /var/log/vdsm/vdsm.log" that log shows the node 
is trying to access NFS based domain which I removed in engine before 
trying to add iscsi data domain. See here:


I am not sure how it got connected to the NFS error. Did you mean 
running "tailf" when you're clicking the "DIscover Targets" button? 
Could you please paste your vdsm.log on http://fpaste.org/

and paste link here?  Thanks.

Re: [ovirt-users] oVirt China User Group?

Get cloud-times involved because probably they could provide resource

the discussion to make the request clear.


A question I have is, when you start adding new content, would we be able to 
have some of it translated into English to use on the ovirt.org?

Thank you so much for the interest! Please reach out to me to coordinate 
community efforts and let me know what you need in terms of content/assistance

Hello,

I'm writing to the list in reference to helping setting up a user group in
China.

As the oVirt community develops rapidly, there is a growing number of users
from China who have deployed oVirt, even in their production environment.
However, there is hardly voice/feedback from these users.

For better spreading oVirt in China, and to help more Chinese users get
into touch with the whole oVirt community, I am going to help setting up a
oVirt user group in China.

Things that the user group might help:
   0. translating articles, discussions, case studies on the oVirt website
   1. organizing online(irc, mailing list) and offline discussions about
oVirt
   2. volunteering in test week
   3. bug fixing
   4. developing features related to localization

By the way, when translating articles, should we setup a new individual
website or just do the l10n work on http://www.ovirt.org? If the former,
should we keep the look and feel the same with the oVirt website?

Great! I have some suggestions.

1. If it is possible, we'd better rent a (virtual/cloud) server inside
China. Sometimes it's very slow to access ovirt.org. Maybe we can also
have a sub-domain name such as cnuser.ovirt.org, and make the outlook of
cnuser the same as oVirt main site.

2. Considering the content, we can start by translating primary pages
and slides in ovirt.org. I think in China most of the technical people
are able to read English, so it is not necessary to translate all the
pages. We shall then provide new content that is different from the
oVirt main site. For example, successful customer stories, technical
experience sharing, and all the things you mentioned in the mail.
