I'm on 3.2.2 el6. Reading that BZ suggests that it is 3.2 related but 
also it speaks of dhw. I don't have the reporting part of ovirt-engine 
installed so don't know it that is causing the zero values.

Re: [Users] Disk statistics

[John Taylor]

I should have pointed to the gerrit that's an external tracker on that. It
shows the root cause is that the disk_image_dynamic table (part of the
engine) isn't getting updated. It's a view of that table that's used for
the stats that you see online and is used by the collector for dwh.

http://gerrit.ovirt.org/#/c/12961/
It says

core: disk_image_dynamic statistics (#892596)


vdsm sends disk statistics per disk, while disk_image_dynamic table
contains disk_image ids (volumes). Hence the update on disk ids that
VdsUpdateRunTimeInfo generates, actually does nothing. A quick fix for
this problem is that VdsUpdateRunTimeInfo now updates by the AI id, so
statistics are saved.

this is a (sadly) known issue in 3.3 beta.
it's supposed to be fixed for GA.
please make sure you are using the correct repo.
the GA version is 3.3.0-4.el6.

reminder to upgrade by re-running engine-setup, not only yum update.

Either you can use the volume set .. option as mentioned in the wikipage
--or --
If the Gluster volume is added / managed to the oVirt UI.. go to 
"Volumes" tab, select the gluster volume and
click on "Optimize for virt. store". That should also set the volume 
options in addition to few other things

[Users] Disk statistics

[Joop]

Hi All,

Because of an question on IRC I looked at 
/api/disks/long-disk-id/statistics but all values (datum) are ZERO. Its 
a disk of a VM that was running a dd if=/dev/vda of=/dev/null so I would 
expect something to show up (Did various webpage refreshes of the 
mentioned stats url). I also have ovirt-guest-agent running on that VM, 
in case it matters and the disk is on a NFS data domain.


What am I missing?

There are only 7 seconds since vdsm's startup until the log ends.
Kumar, would you provide more of vdsm.log?
If now, after several hours, you log into the host and attempt

vdsClient -s 0 getVdsCaps

is vdsm still stuck in its initialization phase, or returns a complete
information?

Hi,
I thought I had replied but apparently I didn't:)
well, the agent is managed by QEMU and oVirt only creates a device in guest for 
use by host's libvirt. Then the oVirt commands for e.g. snapshot or shutdown 
should use qemu-ga for that. AFAIK it wasn't tested thoroughly
If you want to play with it yourself disable the support in vdsm by disabling 
qgaEnable parameter in vdsm.conf

michal

Hi Rene,

Thanks for your reply. My hypervisor is kvm which is already running on
Centos6. Now I understand the fact that I can't simply connect kvm with

yes. you could try to add the host to ovirt-engine, then create a VM, 
then dd the guest into the managed disk by ovirt-engine.
if you use a LUN per disk, you can also use the direct lun disk with 
ovirt-engine without porting/converting the data.




On a different node what is the role of vdsm ?


its the agent on the hypervisor the engine uses to communicate with.

Your hypervisor must be CentOS 6 or Fedora 18/19 in order to be able to
manage it with oVirt (other Linux distributions are still a wip).

As oVirt has a totally different concept as virt-manager you have to
import your machines into oVirt. As Markus already wrote this can be
done using virt-v2v.

Re: [Users] Can not add host to ovirt-engine

[Kanagaraj]

'ovirtmgmt' will be created by engine, you dont need to create one, you 
can check this exists in your host.
from vdsm.log, vdsmd taking time to  complete the initialization. Are 
there any vms running in this host?

fre 2013-09-20 klockan 10:50 + skrev SULLIVAN, Chris (WGK):

Hi,

Just following up on this issue. Turns out the network problems were being 
caused by the bond0 interface.

The initial configuration was two NICs teamed as bond0, which was then bridged 
to the ovirtmgmt interface. With this configuration, RHEL guests could access 
the network normally but Windows guests (XP, 7, 2008 R2) could not. After 
deactivating the bond0 interface and bridging one of the NICs directly to the 
ovirtmgmt interface, both RHEL and Windows guests have fully functioning 
networks.

I am not sure why exactly the bond0 interface was not working as intended. The 
initial configuration had the mode as balance-rr, is this known to cause 
problems? My intention was to have the mode as balance-alb however the bonding 
driver in F19 seems to completely ignore any BONDING_OPTS settings in the 
ifcfg-bond0 file. Attempts to change the bonding mode directly via 
/sys/class/net/bond0/bonding/mode repeatedly failed due to 'the bond having 
slaves', even after the bond had been taken down via ifconfig. I was not able 
to remove the bond0 definition either, even after removing the ifcfg-bond0 file 
and the modprobe.d alias.

Is there a recommended/tested bonding configuration HOWTO for oVirt on F19?


Have you checked the RHEV documentation and searched Microsoft Technet 
for Nic Teaming?


http://technet.microsoft.com/en-us/library/hh831648.aspx - seems MS 
Server 2012 R2 supports a type 4 bond.


An excellent doc about bonding is:

Hi,

we had the same issue (oVirt 3.0 & oVirt 3.2.1) when using balance-rr for VM 
networking:
Windows VM couldn’t access network.

After changing to bond mode to 4 (LACP) , Windows VM networking was possible.

Cheers,

fre 2013-09-20 klockan 10:50 + skrev SULLIVAN, Chris (WGK):



Hi,



Just following up on this issue. Turns out the network problems were being 
caused by the bond0 interface.



The initial configuration was two NICs teamed as bond0, which was then bridged 
to the ovirtmgmt interface. With this configuration, RHEL guests could access 
the network normally but Windows guests (XP, 7, 2008 R2) could not. After 
deactivating the bond0 interface and bridging one of the NICs directly to the 
ovirtmgmt interface, both RHEL and Windows guests have fully functioning 
networks.



I am not sure why exactly the bond0 interface was not working as intended. The 
initial configuration had the mode as balance-rr, is this known to cause 
problems? My intention was to have the mode as balance-alb however the bonding 
driver in F19 seems to completely ignore any BONDING_OPTS settings in the 
ifcfg-bond0 file. Attempts to change the bonding mode directly via 
/sys/class/net/bond0/bonding/mode repeatedly failed due to 'the bond having 
slaves', even after the bond had been taken down via ifconfig. I was not able 
to remove the bond0 definition either, even after removing the ifcfg-bond0 file 
and the modprobe.d alias.



Is there a recommended/tested bonding configuration HOWTO for oVirt on F19?

Well, for what it´s worth, here´s our ifcfg-bond0:
DEVICE="bond0"
NM_CONTROLLED="no"
USERCTL="no"
BOOTPROTO="none"
BONDING_OPTS="mode=4 miimon=100"
TYPE="Ethernet"

And we also have VLAN-interfaces on top of that, and then bridges on top of 
them, and no issues so far.

Found the mode-definitions at "http://www.linuxhorizon.ro/bonding.html":
mode=0 (balance-rr)
Round-robin policy: Transmit packets in sequential order from the first 
available slave through the last. This mode provides load balancing and fault 
tolerance.

mode=1 (active-backup)
Active-backup policy: Only one slave in the bond is active. A different slave 
becomes active if, and only if, the active slave fails. The bond's MAC address 
is externally visible on only one port (network adapter) to avoid confusing the 
switch. This mode provides fault tolerance. The primary option affects the 
behavior of this mode.

mode=2 (balance-xor)
XOR policy: Transmit based on [(source MAC address XOR'd with destination MAC 
address) modulo slave count]. This selects the same slave for each destination 
MAC address. This mode provides load balancing and fault tolerance.

mode=3 (broadcast)
Broadcast policy: transmits everything on all slave interfaces. This mode 
provides fault tolerance.

mode=4 (802.3ad)
IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share 
the same speed and duplex settings. Utilizes all slaves in the active 
aggregator according to the 802.3ad specification.

Re: [Users] Can not add host to ovirt-engine

[Kanagaraj]

'ovirtmgmt' bridge gets created in the host during the 'Initializing' 
phase, may be you can check the existence of this bridge in the host. By 
looking at the log, engine is not able to communicate with the vdsm in 
the host.


Is the there anything in /var/log/vdsm/vdsm.log ?

Thanks,
Kanagaraj

Just to be sure, iptables/firewalld!=Windows Firewall. Is there a rule
in the windows firewall to allow ping or is it disabled?

Don't think so, just converted a Windows2008R2 datacenter guest from
Vmware to oVirt and it ran, after adding virtio drivers or using e1000
and/or ide disks.

Your problem looks like the problem Ren? had with his Solaris guest, its
a recent thread. Turned out that setting -cpu Nehalem by ovirt caused
networking in the Solaris guest to fail.
Don't think this is your problem though since lots of people run Windows
guest without problems.

Re: [Users] Ovirt-engine

[kumar shantanu]

Hi Rene,

Thanks for your reply. My hypervisor is kvm which is already running on
Centos6. Now I understand the fact that I can't simply connect kvm with
ovrit-engine rather I will need to import machines from kvm to ovirt-engine
but my hypervisor will still be kvm ? Am I right ?

On a different node what is the role of vdsm ?

Thanks
Shantanu
