Re: [ovirt-users] Live migration of VM(0 downtime) while Hypervisor goes down in ovirt

[Ranjith P]

Hi,
>>Who's shutting down the hypervisor? (Or perhaps it is shutdown externally, 
>>due to overheating or otherwise?)
We need a continuous availability of VM's in our production setup. If the 
hypervisor goes down due to any hardware failure or work load then VM's above 
hypervisor will reboot and started on available hypervisors. This is normally 
happening but it disrupting VM's. Can you suggest a solution in this case? Can 
we achieve this challenge using glusterfs?
Thanks & RegardsRanjith

I think there are two parts to achieving this:1. Have a script that migrates 
VMs off a specific host. This should be easy to write using the 
Python/Ruby/Java SDK, Ansible or using REST directly.2. Having this script run 
as a service when a host shuts down, in the right order - well before libvirt 
and VDSM shut down, and would be fast enough not to be terminated by 
systemd.This is a bit more challenging.

 Hi Maoz,

 it looks like cannot connect due to wrong setup of ssh keys. Which
 linux are you using?
 The guide for setting the ssh connection to  libvirt is here:
 https://wiki.libvirt.org/page/SSHSetup

 May it helps?

[ovirt-users] 4.2 aaa LDAP setup issue

[Jamie Lawrence]

Hello,

I'm bringing up a new 4.2 cluster and would like to use LDAP auth. Our LDAP 
servers are fine and function normally for a number of other services, but I 
can't get this working.

Our LDAP setup requires startTLS and a login. That last bit seems to be where 
the trouble is. After ovirt-engine-extension-aaa-ldap-setup asks for the cert 
and I pass it the path to the same cert used via nslcd/PAM for logging in to 
the host, it replies:

[ INFO  ] Connecting to LDAP using 'ldap://x.squaretrade.com:389'
[ INFO  ] Executing startTLS
[WARNING] Cannot connect using 'ldap://x.squaretrade.com:389': {'info': 
'authentication required', 'desc': 'Server is unwilling to perform'}
[ ERROR ] Cannot connect using any of available options

"Unwilling to perform" makes me think -aaa-ldap-setup is trying something the 
backend doesn't support, but I'm having trouble guessing what that could be 
since the tool hasn't gathered sufficient information to connect yet - it asks 
for a DN/pass later in the script. And the log isn't much more forthcoming.

I double-checked the cert with openssl; it is a valid, PEM-encoded cert.

Before I head in to the code, has anyone seen this? 

Thanks,

-j

Probably not all ports have been made accessible for VPN users in your 
internal network. E.g. our VPN setup blocks most ports with the 
exception of the usual SSH and http/s ports.  Hence virt-viewer doesn't 
work.


If you have the possibility, connect to a virtual desktop within your 
organization and run your session there.

If I edit the VM, in general settings I see "Other OS" as operating system.
In General subtab after selecting the VM  in "Virtual Machines" tab I again
see "Other OS" in "Operating System" and the field "Origin" filled with the
value "VMware"

During virt-v2v it seems it was recognized as Windows 2008 though...

libguestfs: trace: v2v: hivex_value_utf8 = "Windows Server 2008 R2

libguestfs: trace: v2v: hivex_value_key 11809408

I can send all the log if it can help.

yes
you won’t get any decent performance unless you use virtio drivers. Either 
virtio-block or virtio-scsi

What OS type do you have set for that VM? Make sure it matches the Windows 
version. That enables the hyperv enlightenments settings

Re: [ovirt-users] Ovirt 3.6 to 4.2 upgrade

[Luca 'remix_tj' Lorenzetto]

Hello Gary,

as far as i know upgrade path isn't direct and you have to migrate
first to 4.0, then 4.1 and finally 4.2.

You can migrate vms from 3.6 to 4.0 IIRC. But don't know if mixing 4.2
and 3.6 it's possible.

[ovirt-users] Ovirt 3.6 to 4.2 upgrade

[Gary Lloyd]

Hi

Is it possible/supported to upgrade from Ovirt 3.6 straight to Ovirt 4.2 ?
Does live migration still function between the older vdsm nodes and vdsm
nodes with software built against Ovirt 4.2 ?

We changed a couple of the vdsm python files to enable iscsi multipath on
direct luns.
(It's a fairly simple change to a couple of the python files).

We've been running it this way since 2012 (Ovirt 3.2).

Many Thanks

I seem to remember a similar problem and that deactivating disks of the VM
and the then activating them again corrected the problem.
Or in case that doesn't work, try to remove disks and Then readd from the
floating disk pane...

[ovirt-users] Info about windows guest performance

[Gianluca Cecchi]

Hello,
while in my activities to accomplish migration of a Windows 2008 R2 VM
(with an Oracle RDBMS inside) from vSphere to oVirt, I'm going to check
performance related things.

Up to now I only ran Windows guests inside my laptops and not inside an
oVirt infrastructure.

Now I successfully migrated this kind of VM to oVirt 4.1.9.
The guest had an LSI logic sas controller. Inside the oVirt host that I
used as proxy (for VMware virt-v2v) I initially didn't have the virtio-win
rpm.
I presume that has been for this reason that the oVirt guest has been
configured with IDE disks...
Can you confirm?

For this test I started with ide, then added a virtio-scsi disk and then
changed also the boot disk to virtio-scsi and all now goes well, with also
ovirt-guest-tools-iso-4.1-3 provided iso used to install qxl and so on...

So far so good.
I found this bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1277353

where it seems that

"

For optimum I/O performance it's critical to make sure that Windows
guests use the Hyper-V reference counter feature. QEMU command line
should include

-cpu ...,hv_time

and

-no-hpet

"

Analyzing my command line I see the "-no-hpet" but I dont see the "hv_time"

See below full comand.

Any hints?

Thanks,

Gianluca

Re: [ovirt-users] Cannot Remove Disk

[Andrej Krejcir]

The last workaround I can think of, is to set the quota mode to Audit,
create a new quota and use this new quota for the new disk

Please, can you open a bug and include steps how to get to this state?

Thanks

 Disabling the quota for that DC did the trick. The funny part is it was
 never enabled. I put it in audit mode, tried a delete, got the error... and
 then disabled it.

 Worked, I am a happy camper... Thanks guys.

 The error message means that the data center (storage pool) where
 the quota is defined is different from the data center where the disk 
 is.

 It seems like a bug, as it should not be possible to assign a quota
 to a disk from a different data center.

 To fix it, try setting the quota of the disk to any quota from the
 same data center.

 Andrej​

It shouldn't happen.
I suspect that something went wrong creating the configuration volume on
the shared storage at the end of the deployment.

Alexei, can both of you attach you hosted-engine-setup logs?
Can you please check what happens on

Re: [ovirt-users] Use the "hosted_engine" data domain as data domain for others VM

[Martin Sivak]

Hi,

it should work in general, but there are couple of corner cases to be aware of.

Hosted engine VM should have its disks only on the HE storage domain.
The HE should be installed using the new Node 0 approach (default in
4.2.1+) or it must not use any custom mount options
(https://bugzilla.redhat.com/show_bug.cgi?id=1373930)

For all those reasons we do not recommend using it in production, but
we are not aware about anything that would really block you from doing
it. It just hasn't been tested and polished enough yet.

Best regards

Martin Sivak

Hi,
it will be the default in 4.3.

It's tracked here:
https://bugzilla.redhat.com/show_bug.cgi?id=1451653

I'm not aware of any specific block on 4.2 so it should work on technical
side although it's not the recommended architecture on production systems.
For sure you can actually face some perforce degradation of block device
storage domains (iSCSI and FC) if you have a lot of inactive VMs on the
hosted-engine storage domain due to

No problem.

If you need i can provide you some python-sdk code. I've build an
entire migration tool that interacts with VMware and oVirt to
orchestrate the migration of vms.

Once completed the migration and some cleanup, we'll release it. At
the moment is just a bunch home made libraries connected each other
through a main function that's called through python-rq.

Oooops, sorry!

I misread the window ;-(
The "password" field is under ESXi field, but it is related to vSphere
credentials, not ESXi
In fact inside the window there is only one "password" field.

I just tried and it works. in the sense that with "Load" I see the VMs
inside the DC/Cluster

So you are confirming that using "VMware" import option all fields are

In fact if I don't fill and click "Load", in the ESXi fileds I get the

Re: [ovirt-users] when creating VMs, I don't want hosted_storage to be an option

[Martin Sivak]

Hi,

we got much closer to officially remove the specialty status of both
the domain and the VM in 4.2 with features like Node 0 deployment
(default since 4.2.1) and direct libvirtxml support in engine and HE
(4.2.2 iirc).

There are couple of outstanding issues:

- HE needs to know how to connect all storage domains necessary for HE
VM disks (not 100% related, but close)
- (live) storage migration is not supported yet - HE nodes need to
learn about the new connection details
- changes to gluster topology are not supported yet - same reason as above
- we have a bug with regards to block devices - will be fixed by
https://gerrit.ovirt.org/#/c/87325/
- fencing and SPM role need to be tested a bit more to make sure we
have no surprises there
- old deployments might not have some data in the engine DB
(https://bugzilla.redhat.com/show_bug.cgi?id=1373930)

We will not be adding any additional limits as all seems to work in
the usual cases and we work on removing the remaining restrictions. I
am not 100% certain when it will be finished exactly, but you can use
it now if you are careful (basically do not use custom mount options
and do not add disks to the HE VM that would come from a different
SD!!).

We have two tracking bugs for the related work:
https://bugzilla.redhat.com/show_bug.cgi?id=1455169 and
https://bugzilla.redhat.com/show_bug.cgi?id=1393902 - most of what was
needed was fixed already.

Re: [ovirt-users] Cannot Remove Disk

[Andrej Krejcir]

The error can mean that a quota does not exist for the DC, or was saved in
an invalid state.

Try these steps in the UI:
- Set the quota mode to Audit on the DC
- Check the DC details page, quota tab, if there is a quota defined
  - If not, create one
  - If it is, try editing it and save it. The UI will save a valid quota.

- Set the quota mode back to Disabled.

Hello Martin (and list),
any update on this item to remove specialty of hosted_engine storage?
Any bugzilla RFE or pointer? I think it didn't catch 4.2, correct?

Thanks,

Re: [ovirt-users] Importing Libvirt Kvm Vms to oVirt Status: Released in oVirt 4.2 using ssh - Failed to communicate with the external provider

[Renout Gerrits]

Hi Maoz,

You should not be using the engine and not the root user for the ssh keys.
The actions are delegated to a host and the vdsm user. So you should set-up
ssh keys for the vdsm user on one or all of the hosts (remember to select
this host as proxy host in the gui). Probably the documentation should be
updated to make this more clear.

1. Make the keygen for vdsm user:

   # sudo -u vdsm ssh-keygen

2.Do the first login to confirm the fingerprints using "yes":

   # sudo -u vdsm ssh r...@xxx.xxx.xxx.xxx

3. Then copy the key to the KVm host running the vm:

   # sudo -u vdsm ssh-copy-id r...@xxx.xxx.xxx.xxx

4. Now verify is vdsm can login without password or not:

   # sudo -u vdsm ssh r...@xxx.xxx.xxx.xxx

Re: [ovirt-users] Maximum time node can be offline.

[Martin Sivak]

Hi,

the hosts are almost stateless and we set up most of what is needed
during activation. Hosted engine has some configuration stored
locally, but that is just the path to the storage domain.

I think you should be fine unless you change the network topology
significantly. I would also install security updates once in while.

We can even shut down the hosts for you when you configure two cluster
scheduling properties: EnableAutomaticPM and HostsInReserve.
HostsInReserve should be at least 1 though. It behaves like this, as
long as the reserve host is empty, we shut down all the other empty
hosts. And we boot another host once a VM does not fit on other used
hosts and is places on the running reserve host. That would save you
the power of just one host, but it would still be highly available (if
hosted engine and storage allows that too).

Bear in mind that single host cluster is not highly available at all.

Best regards

Martin Sivak

[ovirt-users] Use the "hosted_engine" data domain as data domain for others VM

[yayo (j)]

Hi,

Is there any problem to use the "hosted_engine" data domain to put disk of
others VM? I have created a "too big" "hosted_engine" data domain so I want
to use that space...

Thank you
