Re: [ovirt-users] Change HostedEngine Storage

[Matt .]

Hi Guys,

Got his sorted out again. Just need to checkout what we can change
about the ca_subject, CN that was previously used when setting it up.

If anyone has info there would be nice.

Cheers,

Matt

[ovirt-users] Change HostedEngine Storage

[Matt .]

Hi guys,


When you want to move your hosted_engine storage you can copy stuff
over but you still need to change the image which contains all config
files.

Is there some documentation about how to do so ?

Thanks,

Matt

File system freezing is implemented using libvirt fsFreese/fsThaw, and is
implemented in the guest with qemu-guest-agent, not ovirt-guest-agent.

You can find the info on using it here:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Using_the_QEMU_guest_virtual_machine_agent_protocol_CLI-libvirt_commands.html

Since 3.6 we use fsFreeze/fsThaw explicitly, so we don't try snapshot twice.

In vdsm log you will find an INFO log before/after fsFreeze/fsThaw, or WARN
log if they failed.

You should check qemu-guest-agent documentation.

Indeed - may be two different issues. Let us know how the NFS works first,
then let's try with iSCSI.

Re: [ovirt-users] Frustration defines the deployment of Hosted Engine

[Vinícius Ferrão]

Hello Adam and Karli,

I will remap uid and gid of NFS to 36 and try again with NFS sharing.

But this does not make much sense, because on iSCSI this should not happen. 
There are no permissions involved and when oVirt runs the hosted-engine setup 
it creates the ext3 filesystem on the iSCSI share without any issue. Here’s a 
photo of the network bandwidth during the OVF deployment: 
http://www.if.ufrj.br/~ferrao/ovirt/bandwidth-iscsi-ovf.jpg

So it’s appears to be working. Something happens after the deployment that 
brokes the connections and kills vdsm.

Thanks,
V.

I’m a traitor of the Xen movement and was looking for some good alternatives 
for XenServer hypervisors. I was aware of KVM for a long time but I was missing 
a more professional and appliance feeling of the product, and oVirt appears to 
deliver exactly what I’m looking for.

Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal 
or better alternatives, but I’m starting to get frustrated with oVirt.

Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my 
notebook, it was a no go. For whatever reasons I don’t know vdsmd.service and 
libvirtd failed to start. I make sure that I was running with EPT support 
enabled to achieve nested virtualization, but as I said: it was a no go.

So I’ve decommissioned a XenServer machine that was in production just to try 
oVirt. The hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 
48GB of system RAM, but I can’t get the hosted engine to work, it always 
insults my hardware: --- Hosted Engine deployment failed: this system is not 
reliable, please check the issue,fix and redeploy.

It’s definitely a problem on the storage subsystem, the error is just random, 
at this moment I’ve got:

[ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response 
for JSON-RPC StorageDomain.detach request.

But on other tries it came up with something like this:

No response for JSON-RPC Volume.getSize request.

I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so 
I’ve changed to an iSCSI backend, but the problem continues.

Can't say anything about your issues without the logs but there's nothing wrong 
with FreeNAS (FreeBSD) NFS, I've been running oVirt with FreeBSD's NFS since 
oVirt 3.2 so...

Could you share your relevant exports configuration to make sure he's using 
something that you know works?


"You're holding it wrong":) Sorry, I know you're frustrated but that's what I 
can add to the conversation.

/K

This happens at the very end of the ovirt-hosted-engine-setup command, which 
leads me to believe that’s an oVirt issue. The OVA was already copied and 
deployed to the storage:

Re: [ovirt-users] Frustration defines the deployment of Hosted Engine

[Vinícius Ferrão]

Hello Adam,

Since the NFSv3 server is running on a FreeBSD based system I don’t want to 
mess with permissions (that installation was only a test). So I’ve mapped all 
users to root and all groups to wheel: everyone has permission to do anything 
on any file.

# cat /etc/exports
/mnt/pool/ovirt  -alldirs -mapall=root:wheel 146.164.36.137

The issue happens on the same point, either on NFS or on iSCSI.

And finally here are the files:
http://www.if.ufrj.br/~ferrao/ovirt/

V.

I think this might be part of your problem.  The host drops privileges to
vdsm:kvm and needs to work with files which may not be world writable.
Consider changing the above to:

/mnt/pool/ovirt  -alldirs -mapall=36:36 146.164.36.137

Since the vdsm user is always 36 and the kvm group is always 36.

Please provide links to the files /var/log/vdsm/vdsm.log
and /var/log/sanlock.log on the host you are attempting to use.  Does the
problem happen in the same step when using NFS vs. ISCSI?  How are you
configuring the NFS export that you give to hosted-engine to use?

[ovirt-users] Frustration defines the deployment of Hosted Engine

[Vinícius Ferrão]

Hello oVirt folks.

I’m a traitor of the Xen movement and was looking for some good alternatives 
for XenServer hypervisors. I was aware of KVM for a long time but I was missing 
a more professional and appliance feeling of the product, and oVirt appears to 
deliver exactly what I’m looking for.

Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal 
or better alternatives, but I’m starting to get frustrated with oVirt.

Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my 
notebook, it was a no go. For whatever reasons I don’t know vdsmd.service and 
libvirtd failed to start. I make sure that I was running with EPT support 
enabled to achieve nested virtualization, but as I said: it was a no go.

So I’ve decommissioned a XenServer machine that was in production just to try 
oVirt. The hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 
48GB of system RAM, but I can’t get the hosted engine to work, it always 
insults my hardware: --- Hosted Engine deployment failed: this system is not 
reliable, please check the issue,fix and redeploy.

It’s definitely a problem on the storage subsystem, the error is just random, 
at this moment I’ve got:

[ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response 
for JSON-RPC StorageDomain.detach request.

But on other tries it came up with something like this:

No response for JSON-RPC Volume.getSize request.

I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so 
I’ve changed to an iSCSI backend, but the problem continues. This happens at 
the very end of the ovirt-hosted-engine-setup command, which leads me to 
believe that’s an oVirt issue. The OVA was already copied and deployed to the 
storage:

At this point I really don’t know what I should try. And the log file is too 
verborragic (hoping this word exists) to look for errors.

Any guidance?

V.

Re: [ovirt-users] Dell firmware update problem

This is a multipath issue. I’d suggest to stop multipathd service before 
applying Dell updates. This will not affect currently running multipath devices.

hi,

i'm looking for a way to change the SPICE keymap for a VM. i couldn't

as i said, it was easy. it's obviously a matter of guest OS keymap

i found configuration stanzas for qemu like




via google. i don't know if this is obsolete, i was suspicious from the

Hi,

An arbiter volume is a special class of replica-3 volume. Arbiter is 
special because the third brick of replica set contains only directory 
hierarchy information and metadata. Therefore, arbiter provides 
split-brain protection with the equivalent consistency of a replica-3 
volume without incurring the additional storage space overhead.


If you already have a replica volume in your config with three 
bricks then that config should be good. You do not need to create a 
arbiter.


Hope this helps !!

Thanks

kasturi

[ovirt-users] Dell firmware update problem

[Davide Ferrari]

Hello


I'm trying to update the BIOS firmware on a Dell PowerEdge with CentOS 
(just upgraded to 7.3) running oVirt 4.0 and it fails with an error


mount: /dev/sdb is already mounted or /tmp/SECUPD busy

The problem is acknoleged by Red Hat and there is a solution for it

https://access.redhat.com/solutions/2671581

but well, I have no RH subscriptions :( Has anyone here encountered the 
same problem with CentOS and oVirt? Any hint?



Thanks!

Ok.

What's exactly the role of "guaranteed memory"? Is only about ensuring
on startup time that there is at least X free memory on hosts or
something more complex?

What's the best configuration? keeping baloon or not? setting memory
and guaranteed memory to the same value?
If i have 1TB of ram in all the cluster, does the "guaranteed memory"
doesn't allows to provision vms with cumulative guaranteed memory
usage greater than 1TB?
Can KSM help allow to overprovision in this situation?

Does memory baloon device has impacts on vm performance?

I need to understand better in order to plan correctly all the
required hardware resource i need for migrating to oVirt.

Re: [ovirt-users] Hot Memory add and Physical Memory guaranteed

[Martin Sivak]

And I believe the virt team is working on "hotplug" support for the
guaranteed memory so mom will start changing the balloon size
accordingly.

Michal: is there a bug tracking that?

This is normal with memory balloon enabled – memory balloon often
"consumes" the hot plugged memory, so you can't see it.
