[ovirt-users] Cumulus Switch
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.

[ovirt-users] Gluster + ovirt + resize2fs
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?

[ovirt-users] Migration Return Errors
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 ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Windows Networking Issues -
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 -
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 -
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. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] qlnic errors -
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
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 ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
