Hi David,
I try to use yum update but i have this error :
yum update
Loaded plugins: fastestmirror, imgbased-warning
Warning: yum operations are not persisted across upgrades!
The problem is that on the server i have this repository:
ovirt-4.0.repo
ovirt-4.0-dependencies.repo
With this repository it's possible upgrade ovirt only only between minor
releases for example from 4.0.1 to 4.0.6, i want to upgrade the host from

Re: [ovirt-users] [ovirt-devel] Networking fails for VM running on Centos6.7.Works on Centos6.5

2015-11-29 Thread mad Engineer
each vm has 4 nics connected to 4 different  bridges which is
connected to 4 different physical interface in access mode VLAN.No
bonding between interfaces.I have IP assigned on "ovirtmgmt" bridge
which is used for storage,migration,console and VM internet access.All
interfaces are 10G with MTU 9000.
During my test only change i made was booting to centos6.5 kernel.

Facing another issue with PXE booting guest machines switching to old
kernel fixes this too

[ovirt-users] Networking fails for VM running on Centos6.7.Works on Centos6.5

2015-11-28 Thread mad Engineer
hello all i am having strange network issue with vms that are running on
centos 6.7 ovirt nodes.

I recently added one more ovirt node which is running centos6.7 and
upgraded from centos6.5 to centos6.7 on all other nodes.

All VMs running on nodes with centos6.7 as host Operating system fail to
reach network gateway,but if i reboot that same host to centos6.5 kernel
everything works fine(with out changing any network configuration).

Initially i thought it as configuration issue but its there on all nodes.if
i reboot to old kernel everything is working.

I am aware about ghost vlan0 issue in centos6.6 kernel.Not aware about any
issue in centos6.7 Also all my servers are up to date.


All physical interfaces are in access mode VLAN connected to nexus 5k
switches.


working kernel- 2.6.32-431.20.3.el6.x86_64

non working kernel- 2.6.32-573.8.1.el6.x86_64

[ovirt-users] Upgrade oVirt 3.6

2015-11-04 Thread Massimo Mad
Hi,
I tried to do the update manager oVirt, it appears to me the following
message:
Setup will not be able to rollback new packages in case of a failure,
because the following installed packages were not found in enabled
repositories:

python-websockify-0.5.1-1.el6.noarch

I checked on the Epel repository, and version of the package indicated there
isn't.
There is only the version python-websockify-0.6.0-3.el6.noarch.rpm
How can I do if I need the rollback?

[ovirt-users] oVirt Node

2015-10-20 Thread Massimo Mad
Hi,
I want to migrate my hosts from centos centoes 6.x to 7.x and at the same
time move from a normal installation centos with then installed oVirt to
oVirt node.
But I noticed that there is not always the latest release of oVirt node, for
example, the latest version of oVirt node is 3.5.2 and the latest version of
oVirt is 3.5.4.
Where can I find the latest release of oVirt node, or there is a kickstart to
create the hosts.

[ovirt-users] Upgrade Infrastructure

2015-05-04 Thread Massimo Mad
hello,
where can I find a document that explains how to upgrade my oVirt
infrastructure?
My infrastructure is currently composed of host centos 6.x who would like
to upgrade to host centos 7.x.
I can co-exist in the same cluster temporarily host with different releases
or should I create a new cluster and then migrate vm?

 Also I have found that if you don't have the engine in DNS or /etc/hosts

 Hi,
 I've a two nodes hosted-engine ovirt 3.5used storage is NFS4 for the:
 engine, vms, iso and export
 I have many Linux VMs and one Windows 2008 VM.
 The windows 2008 VMs is acting as a second AD, it's the second time in a
 month where the VM hangs and the cpu usage is 100%.I have this problem only
 with this VM only.

 I tried to look into vdsm logs, but no luck so far, all I found
 isGuestMonitor-Win2k8x64-AD2::DEBUG::2015-02-11
 12:01:02,158::vm::486::vm.Vm::(_getUserCpuTuneInfo)
 vmId=`ce0bcb92-90e8-45a7-9b9f-cfed10e920d6`::Domain Metadata is not set

 Is there a log file where I can follow the behaviour of the VM, because
 for now I have no clue about what is causing this problem.
 any advice?
 PS: is there a good solution to gather and analyze all the logs from
 ovirt's hypervisors and engine, storage...etc?

 thanks in advance.

 Hi,

 I looked at the logs and the reason why host vmh-02 wasn't
 restarted is that PM restart failed using both other hosts
 (vmh-01 and vmh-03) with error:

   Test Failed, [Powering off machine @ IPMI:10.9.1.11...Failed

 So we couldn't restart HA VMs on another hosts, because we were
 not sure that host vmh-02 is really down.

 I also noticed that even getting PM status of host vmh-02

Re: [ovirt-users] Adding multiple NFS storage and migrate volumes to other

2015-02-01 Thread mad Engineer
Thank you all for your quick response,
   i have one more
query,if i pause all vms and put hosts to maintenance and then in the
NAS after adding disks can i copy data from share1{with older disks}
to share2{new disks} and later remove share1 and rename share2 to
share1.Finally resume hosts and vms,can this method work?
There is no change in the NFS ip address nor in sharename,only change
is in hard disk type.

This is our backup approach if we can not find one more NAS.

Do you find any issue with this approach.

[ovirt-users] Network performance drop when compared to other hypervisor with vhost_net on for UDP

2015-01-14 Thread mad Engineer
I am running RHEL6.5 as Host and Guest on HP server.
Server has 128G and 48 Core[with HT enabled.]

3 VMs are running 2 pinned to first 24 PCPU with proper NUMA pinning,

Guests:

VM1:
6 VCPU  pinned to 6 PCPU NUMA node 1,with 16G RAM

VM2:
6 VCPU pinned to 6 PCPU on NUMA node 0,with 16G RAM

VM3:
2 VCPU ,no pinning,4G RAM

HOST
host has 10 free CPU+24 HT threads which is not allocated and is available.
Host also runs a small application that is single threaded,that uses ~4G RAM.

Total resource to host is 10 CPU+24 HT=34 and 92G unallocated RAM[VMS
dont even use 70% of allocated RAM] also ksm is not running.

Networking:
Uses linux bridge connected to 1Gbps eth0,with ip assigned on eth0
[This IP is called for accessing application running on host]
All vms use virtio and VHOST is on .

Traffic on virtual machines are ~3MBps and combined traffic on host is ~14MBps

VHOST-pid-of-qemu-process sometimes uses ~35% CPU.


There is no packet loss,drop or latency,but the issue is with the same
setup on Vmware with same sizing of virtual machines,with the only
difference as application running on host has moved to fourth VM.So in
Vmware there are 4 VMs.
Application gives better number ie on KVM that number is 310 and on
vmware it is 570.Application uses UDP to communicate.

I tried removing VHOST,still value is same.(I hope VHOST-NET UDP issue
is solved)

Thanks for any help

 from the top of my head you could try to play with tuned both with guest and

 ###Install###
  yum install tuned
  /etc/init.d/tuned start
  chkconfig tuned on

 ###usage###
 list the profile:
  tuned-adm list

 change your profile:
 tuned-adm profile throughput-performance

 maybe try to experiment with other profiles.

 Total resource to host is 10 CPU+24 HT=34 and 92G unallocated RAM[VMS
 dont even use 70% of allocated RAM] also ksm is not running.

 Networking:
 Uses linux bridge connected to 1Gbps eth0,with ip assigned on eth0
 [This IP is called for accessing application running on host]
 All vms use virtio and VHOST is on .

 Traffic on virtual machines are ~3MBps and combined traffic on host is 
 ~14MBps

 VHOST-pid-of-qemu-process sometimes uses ~35% CPU.


 There is no packet loss,drop or latency,but the issue is with the same
 setup on Vmware with same sizing of virtual machines,with the only
 difference as application running on host has moved to fourth VM.So in
 Vmware there are 4 VMs.
 Application gives better number ie on KVM that number is 310 and on
 vmware it is 570.Application uses UDP to communicate.

 I tried removing VHOST,still value is same.(I hope VHOST-NET UDP issue
 is solved)

 Thanks for any help

Re: [ovirt-users] ksmd high cpu usage from almost a week with just one vm running

2014-12-07 Thread mad Engineer
Thanks Doron,
 Can you confirm this behaviour,i changed (defvar
ksm_free_percent 0.10) and restarted vdsm and now ksmd is behaving
normally.But i don't understand why its behaving aggressively when
free RAM percentages is 22% even though its close to 20 :)

 Hi,
 you can see all the relevant definitions in mom's ksm policy.
 The trigger to run ksm is defined here:
 https://github.com/oVirt/vdsm/blob/master/vdsm/mom.d/03-ksm.policy#L23

 You can change this setting (in each host you have) to something that
 suits your load. We have the below bug opened and hopefully handle it
 in one of the next versions.

 Hi,

 What do you mean by shared iscsi?
 if you created a new iSCSI Storage Domain in the Data Center and it is active 
 then all the hosts should see it while it is Active.

 First step the admin guide:

 and in particular the Storage chapter and the related iSCSI part:

Re: [ovirt-users] shared storage with iscsi

2014-12-04 Thread mad Engineer
sorry i am wrong its the data domain that stores virtual disk images,I
have no idea how ovirt shares block device across hosts.Looks like i
need to try that for understanding how its implemented.In case of
vmware they uses vmfs file system for sharing block device among
hosts.I currently have no issues with my NFS shared storage so dont
have any plan to use iscsi,but just curious how the implementation
is.In my existing non ovirt environment,SAN block devices is exported
and its shared using GFS.Is ovirt using any simillar method to achieve
shared block device.

[ovirt-users] Node down,but ovirt still shows VM as up

2014-06-27 Thread mad Engineer
Hi,
 I am using Cisco UCS C200 M2 as Host running Centos 6.5 and  KVM,


Power Management not working properly,hence even with Node down Ovirt shows
VM as still up,with uptime of VM increasing(on the manager)


if i continue and save the changes its causing problems:

1. HA is not working ( Node status changed to Non responsive but VM status
still up!!
 2. Restart of Host gives wrong information-it shows host as rebooting but
actually nothing is happening to Host!!

While configuring power  management:

On ovirtmanager edited Power management and chose  cisco_ucs with proper
authentication to CIMC,but when clicked on test,it shows


*Test Failed, Failed: You have to enter plug number Please use '-h' for
usage *

What is this plug,i couldn't find anything in CIMC

This can be the reason for failure of HA and restart

Can someone please help me fix this

  vboxmanage clonehd --format RAW VMNAME.vmdk NewVMName.raw
  d.Convert the created RAW file to a qemu2 img:
  qemu-img convert -f raw VM-Name.raw -O qcow2 VMName.qcow2

[ovirt-users] Tune HA timing,is it possible

2014-06-27 Thread mad Engineer
Hi,
 Is it possible to tune time required to reboot VM in case of  host
failures.

in our test  we powered off one of the Host.

Manager was still showing both Guest and Host as UP for around 5 minutes
 and after that it took another 4-5 minutes to start VM.

Is there any tunable parameter that can be modified to bring down the time
required to recognize Host failures.

   I think that's the issue,i havent configured any

  i see Address,Username,Password,SSH port and Type.

  Using HP server with ILO2 so i filled Type as ILO2 but its confusing
 what these

 * Address,Username,Password *are

  are these ILO credentials or My hypervisor credentials


  ILO credentials.

 Hi,

 - Original Message -
  Hi i was testing HA of ovirt,(i am from Xenserver background and trying
 to
  use KVM solution in our environment)
 
  Have 2 hosts with NFS storage and i tested migration between these two
 hosts.
 
  On Host2 while VM was running on it, i unplugged Power cable and it took
 long
  minutes to update that VM is down,okkk now long wait..
  ..
  .
  ...
 
  VM state changed to unkown and not booted on second Node ie Host1
 
  its been half an hour and still the VM is not restarted
 
  What can be the issue?What should i do it make the VM in real HA so that
 it
  will be restarted on the active node.

 We don't restart the VM in that case on purpose, since we really don't know
 what's the status of the VM - the host might have been just disconnected
 from
 the network while the VM is still running (and connected to the storage),
 so if we'll also run the VM on a different host, we'll get split-brain.

 In order to restart HA VMs which were running on host that went down, you
 either
 needs to have power-management defined for that host (for automatic
 restart) or
 to trigger it manually by selecting confirm host has been rebooted when
 the
 host is changed to non-responsive state (and you need to have additional
 host
 which is up of course).

 
  How HA is enabled
  what i did was while creating vm Advanced optionHigh
 AvailabilityHighly
  Available
 
  I am sure this can be a configuration error,Can some one please help me
 with
  enabling HA.
 
  Please Help
 
  Thanks

Re: [Users] Correct way to change graphics adapter?

 Can I change the qemu xml somewhere?

 can you please explain the use case?

We have software developers who need VMs to test their software and for
some test a display of 1280x1024 is necessary. The default cirrus
graphics card is not good enough for that.

But we have some VMs which use a Red Hat Virtual graphics adapter and we
don't know how this happened or how it is configured.

We just figured out that the difference may be connecting with SPICE or VNC.

Is there a different way to change the grapics card permanently?

[Users] Switching storage type?

2014-03-10 Thread mad
Hi,

Is it possible to switch a storage type with VMs still on it?

I have a datacenter with a local storage and I want to switch it to NFS
(or Gluster). Setting up the NFS on the directory is not a problem but I
can't detach the storage with VMs on it.

The next question would be if I could import the domain as NFS if it was
a local storage before.

TIA
