[ovirt-users] Cumulus Switch

2016-12-15 Thread Matt Wells
I've seen some of the cool stuff coming with OVN and even a co-worker has
done some great things with it.  However I was wondering if anyone had
experience with Cumulus as the external provider for networks.
It's just a "weekend project" I'm picking up and thought to ask on the
list.  I've not found other posts on it yet but will continue to look.
I've just made a fresh lab with the latest and greatest oVirt on CentOS 7.

[ovirt-users] Gluster + ovirt + resize2fs

2016-06-01 Thread Matt Wells
Hi everyone, I had a quick question that I really needed to bounce off
someone; one of those measure twice cut once moments.

My primary datastore is on a gluster volume and the short story is I'm
going to grow it.  I've thought of two options

1 - add a brick with the new space
** Was wondering from the gluster point of view if anyone had a best
practice for this.  I've looked around and find many people explaining
their stories but not a definitive best practices.


2 - as I'm sitting atop LVMs grow the LVM.
** This is the one that makes me a little nervous.  I've done many
resize2fs and never had issues, but I've never had gluster running atop
that volume and my VM's atop that.  Has anyone had any experiences they
could share?

Thanks all -

[ovirt-users] Migration Return Errors

2015-12-10 Thread Matt Wells
We're running oVirt 3.5 in a two node setup.  We've had some storage issues
and getting it humming with Gluster but this seems to have all of that
squared away.  Our problem is peculiar and I wanted to ask the list to see
if anyone else has had this.  In short you can migrate a VM from one host
to the other  but once there it can not return to it's original host.
We attempted a few things yesterday and with testing today I'll attach logs
shortly.

** Environment
Hosts name -
Host1.example.com
Host2.example.com

VMs name -
Server1.example.com
Server2.example.com

This is a hosted-enginge configuration but all seems to be working well.
Even the hosted-engine shows this behavior but I'm focusing on Server 1 and
2; not the engine as I believe it complicates the tests.

* Both nodes are operational with no power management setup
* All VMs reside within the vm_storage mount point
* At this time there is only one Network; it has the VMs and hosts.  This
will be broken up after this is resolved.
* Server1 migrates (by hand ) from Host1 to Host2 with no issues
* Server2 is powered on atop Host1 with no issues; leaving one VM on both
hosts
* I attempt to migrate Server1 back to Host1 and he states there is no
available hypervisor
* I can reboot Server2 with no issues, create a new VM on Host1
* A VM can only migrate onces, never able to return from whence it came
The only way to force this is to place Host1 in maintenance mode and
activate again. After this Server2 can return to Host1 but then is unable
to go back to Server2; being in the same cycle

Re: [ovirt-users] Windows Networking Issues -

2015-12-01 Thread Matt Wells
I wanted to follow up on this after I found my resolution.

I started to see kernel errors when I migrated all but my windows host off
a hypervisor and generated traffic.  I then took those errors and started
looking back at all of the hypervisors only to find this error was on each
of them; also it actively reporting on systems with Windows VMs.  Tracing
back the logs lead me to the bug reports below where I learned that this
issue had been re-introduced to the 2.6.32-X kernel.

Re: [ovirt-users] Windows Networking Issues -

2015-11-25 Thread Matt Wells
All networking within oVirt seems fine.  I can ping devices on other
networks, I'm able to use a squid proxy on the same network with no
issues.  I'm able to use Terminal Services from another VM in oVirt.  One
oddity is when I first boot, I'm able to hit Google and search for a Dog.
On my 2nd search it starts to timeout.

All and all ip networking seems to be configured well.  The DG lives
outside of oVirt and I'm always able to ping it; even increasing the packet
size.

MTU size is 1500 and matches the VLAN MTU in oVirt; the bond0 is set to set
to an 9000 MTU.
EM1 and EM2 are in bond0 and show no framing errors.

[ovirt-users] Windows Networking Issues -

2015-11-24 Thread Matt Wells
Hi all, I have a question about Windows VMs and a networking issue I'm
having.

Here's the setup -
* oVirt - 3.5.1.1-1
* Hypervisors are CentOS 6.7 box with 2 NICs in bond0 'mode=4 miimon=100
lacp_rate=1'
* On bond0 I have a few networks using vlan tagging.
* Networks are 5,10,15,20 - All on an external switch

Network 15 has a Windows 2012 R2 server and a CentOS 6.7 server on it.
The rest of the networks have a few linux.

Every linux box on every network is happy.  However any and all Windows
boxes I bring online are incapable of patching or hitting the web.  I
pointed the Windows box to the linux box next to it as a proxy (after
installing squid on it)  When I do that the Windows box has no issues at
all; it's only when he's attempting to leave on his own.

On my firewall I put in a 'permit any any' on the M$ box IP however all I
see is tcp resets in PCAPs,

I've been playing with for some time but can't seem to find the issue.  It
would be one thing if everything on the 15 was bad but the linux box on the
network is fine. Here's the rub, I'm 99.999% sure this used to work.
 gggrrr...

Any assistance anyone can offer would be amazingly appreciated.

Thank you for taking the time to read this.

[ovirt-users] qlnic errors -

2015-04-08 Thread Matt Wells
I'm doing a product demo for one of our customers.

They've setup RHEV 3.5 on a Dell Blade center. We also used 3.4 to
start this demo. So far they've been less than impressed as we have 10
VM's that are just putting some traffic on the system. Under any load
the blades network card driver fails and the VMs are then paused.

Under ESX the same blades have no issues at all. We started with Dell
on this but were unable to find any issues with these systems related
to hardware.

Running on the 3.5 node (even setup one blade as a RHEL + VDSM) and we
continue to get the same errors.

They continue to get this on the 3.5 node image, 3.4 node image,
RHEL{6..7}+VDSM, CentOS{6..7}

[ovirt-users] HA of VMs

2015-02-24 Thread Matt Wells
I've been poking around for a better way to perform HA.  With VM's like IPA
or even HA web sites behind an HAProxy; how do I ensure that they are never
on the same host?

I've seen the options for watchdog and I can see where that may help a
little, but not without the initial outage to trigger the alert.  There are
many ways to do this however I see few that scale.
I'm sure I'm missing something and I really appreciate any guidance.
Thanks all
