el6 and el7 clusters and SPM
by Sigbjorn Lie 13 Mar '16

13 Mar '16

Hi I am looking to migrate several el6 rhev-h nodes to el7 rhev-h nodes. There are multiple clusters in the datacenter and it will take a while (several months) to have all the clusters in the data center migrated to el7. Is there be any potential issues to look out for with regards to having the SPM for this datacenter running on a el6 or a el7 node in this datacenter? Any cross compatability issues to look out for? RHEV-M is currently at version 3.5.6. We are using FC storage. Regards, Siggi

MAC spoofing for specific VMs
by Christopher Young 13 Mar '16

13 Mar '16

I'm working on some load-balancing solutions and they appear to require MAC spoofing. I did some searching and reading and as I understand it, you can disable the MAC spoofing protection through a few methods. I was wondering about the best manner to enable this for the VMs that require it and not across the board (if that is even possible). I'd like to just allow my load-balancer VMs to do what they need to, but keep the others untouched as a security mechanism. If anyone has any advice on the best method to handle this scenario, I would greatly appreciate it. It seems that this might turn into some type of feature request, though I'm not sure if this is something that has to be done at the Linux bridge level, the port level, or the VM level. Any explanations into that would also help in my education. Thanks, Chris

Understand CPU Socket Cores and VCPU
by Taste-Of-IT 10 Mar '16

10 Mar '16

Hello, i have a general Question about Hardware CPU, Socket, Cores and the VCPU, Cores per VSocket and VScoket for virtual Machines. Example i have a single CPU with 4 Cores and 8 Threads. As far as i understand i should configure the virtual machines with that number of socket as the host has. So in this example with max 1 Socket. How is the possibility in VCPUs and VCores? What is the limit in this example? Can i only run max 4 VMs? Thanks for clarifying Taste

I'm very new = to ovirt, so some of the basics are still new to me. I currently have a 3 node setup which are all configured without vmfex, wha= t I'd like to do is convert the hosts one by one to use vmfex. >From the UCS side of things it works and I'm presented with the SRIOV devic= es in the host.. but I can't get the network config in the ovirt admin setu= p.. I'm following this guide, but not getting very far... http://www.ovirt.org= /Features/UCS_Integration This step says to do this, which is fine.. but when I do this I overwrite t= he current attribute in there. engine-config -s CustomDeviceProperties=3D'{type=3Dinterface;prop=3D{vmfex= =3D^[a-zA-Z0-9_.-]{2,32}$}}' which is... # engine-config -g CustomDeviceProperties CustomDeviceProperties: version: 3.0 CustomDeviceProperties: version: 3.1 CustomDeviceProperties: version: 3.2 CustomDeviceProperties: version: 3.3 CustomDeviceProperties: {type=3Dinterface;prop=3D{SecurityGroups=3D^(?:(?:[= 0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}, *)*[0-9a-fA-F]{8}-(?:[= 0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.4 CustomDeviceProperties: {type=3Dinterface;prop=3D{SecurityGroups=3D^(?:(?:[= 0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}, *)*[0-9a-fA-F]{8}-(?:[= 0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.5 CustomDeviceProperties: {type=3Dinterface;prop=3D{SecurityGroups=3D^(?:(?:[= 0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}, *)*[0-9a-fA-F]{8}-(?:[= 0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.6 When I update it using the command above, it replaces it...

Not seeing Gluster options on Cluster properties
by Will Dennis 01 Mar '16

01 Mar '16

Hi all, I am running a hyperconverged setup of oVirt 3.6, where I pre-made the Gluster volumes that are used for the hosted engine and the VM storage domains. I have seen in screenshots of 3.6 HC setups that there should be options to enable Gluster integration in oVirt by checking a box in Cluster properties > General tab (“Enable Gluster Service”) but I do not see that checkbox in my Cluster properties > General tab. What must I do to enable this integration? BTW, I see that there is a package "vdsm-gluster-4.17.18-0.el7.centos.noarch” installed on all of my oVirt nodes… Is there another package that I am missing? Thanks, Will

virt-v2v converting multi-disk
by Clint Boggio 01 Mar '16

01 Mar '16

I'm in the process of migrating a series of VM's from KVM environment, to an OVirt environment. I've used virt-v2v to convert quite a few M$ and Linux machines with great success. Coming up I've got to convert a Linux VM that has 3 virtual disks. Inside that VM, the three disks are part of an LVM volume. 1. How will virt-v2v handle these three virtual disks ? 2. On which disk image will I run virt-v2v ? 3. Will virt-v2v "follow" the three images and convert the machine or will I have to somehow tell it to include all three disks ? 4. Shall I have all three images together in the same directory when I run the tool ? 5. Is this the appropriate forum for this question ? As of the writing of this question I'll be using OVirt 3.6 updated on a 4 node cluster running CentOS 7 , and the most recent version of virt-v2v as is available on Fedora 23.

oVirt New Install
by Brett I. Holcomb 01 Mar '16

01 Mar '16

I am in the process of testing oVirt to replace ESXi 6 and have run into some issues that I haven't found answers to. I've used ESXi for quite a while and done some work with Microsoft's Hypervisor but am new to oVirt. It looks like it has potential to replace the others but there are some major issues I'm trying to work through. I'm using a hosted-engine deployment. The host is a guest on VMware Workstation 11 on Windows. Not the best but it lets me test oVirt. I've created the VM, the engine is installed, the webadmin works, and I can SSH to it but I'm seeing some things that I haven't been able to find answers to so any help is appreciated. I'm using DNS to resolve and both the engine and host can ping each other, reverse lookup on their names works. 1. I used an iSCSI LUN on a NAS for storage during the deploy install but this storage does not show up in the admin portal list of storages. Is it supposed to? It's being used as it now has 3+ our of 50 gig used. 2. I used a local directory on the VM for an initial ISO domain but it does not show up in the admin portal. I have more than 15 Gig of space available. Shouldn't it be showing up in the list of storages? I tested using this (http://www.ovirt.org/documentation/how-to/troublesho oting/troubleshooting-nfs-storage-issues/) and from the host I can mount the engine's exported directory and create a file in it as the vdsm user. 3. My host wants confirmation it's rebooted which it has been both with hosted-engine vm-shutdown/vm-start, and rebooting from within the engine. If I tell it to confirm I get the message below. Well, it's status is running. i can't connect when it's connecting or non- operational!! I've put the system into maintenance mode with hosted- engine commands, I used the context menu on the hosted-engine vm in the portal to put it into maintenance but it still refuses to confirm it's rebooted. Any ideas on how to get it confirmed. I've also rebooted the hosted-engine host with no change. "Error while executing action: Cannot confirm 'Host has been rebooted' Host. Valid Host statuses are "Non operational", "Maintenance" or "Connecting"." 4. My Default Data Center is uninitialized which is probably why nothing works. If I use guide me and attach the hosted_engine choice it tells me it cannot acquire a host id. I restarted the sanlock service and then when I attached the storage the dialog hung up spinning it's wheel and never returned. I restarted the VM from hosted-engine and still get the AcquireHostId failure. The iSCSI lun is being used and accessed by the engine as there is 3+ gig of space used. If I try and attach the hosted_engine storage the icon changes to a wrench, then back to the red down arrow and I get the error about not acquiring a host id. What host id? I only have one host! I've reinitialized the lockspace all with no effect. The /var/log/ovirt- engine/engine.log has this error. What invalid argument? I've seen some bug reports on this but they are back in version 3.3 or so and are supposed to be fixed. Command 'org.ovirt.engine.core.bll.storage.AddStoragePoolWithStoragesCommand' f ailed: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericExcep tion: VDSErrorException: Failed to CreateStoragePoolVDS, error = Cannot acquire host id: ('1d26d977- 0a67-43ab-bfb8-462cea95029a', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argumen t')), code = 661 (Failed with error AcquireHostIdFailure and code 661) Any help is appreciated. Thanks.

macvlan + IPv6
by Jay Turner 29 Feb '16

29 Feb '16

Hoping someone can help with a problem my team is seeing under oVirt. We are making heavy use of macvlan interfaces (in VEPA mode) on-top of virtual functions, under VMs being managed by oVirt. In this scenario IPv6 is not playing nicely, with no traffic going through, and messages about neighbor solicitation. There are some pointers out there indicating the issue stems from the fact IPv6 utilizing multicast for neighbor solicitation, but nothing we have tried seems to work around this issue. The problem is made all the most bizarre by the fact that on the same hardware libvirt + virt-manager works perfectly fine. I have looked at the corresponding xml for the guests, and nothing seems to point to the underlying cause for oVirt to fail, but libvirt to succeed. * Intel XL710 40G NICs (i40e/i40evf drivers) * CentOS 7.1 (fully up-to-date) * oVirt 3.6 * libvirt-1.2.17 * virt-manager-1.2.1-8 Thanks for any pointers folks can provide. - jkt
