shutting down a host witn running vms on it.
by Nathanaël Blanchet 14 Mar '16

14 Mar '16

Hi all, What is the behaviour of a host with running vms when a reboot is initiated, for instance by a powerchute shutdown event or an init event? In such a case, will vms will properly shutdown? Thank you for your help. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Impact of changing VLAN of ovirtmgmt in the Data Center?
by Garry Tiedemann 14 Mar '16

14 Mar '16

Hi everyone, In Data Centers > (Name) > Networks section of the Ovirt GUI, network definitions include the VLAN IDs. In my case, the VLAN ID of ovirtmgmt has been empty (meaning VLAN 1) since I built it; it's always been wrong. My hypervisor hosts' ovirtmgmt bridges are actually in VLAN 20. An error message alerted me to this mismatch a few days ago. None of my production VMs are on VLAN 1, or VLAN 20, but I'd like to confirm if it's safe to change this. Can changing the VLAN ID of ovirtmgmt within Data Center > Networks impact VMs from other VLANs? I see no reason why it should be a problem. We just need some certainty on that point. Thankyou in advance for answers. Regards, Garry PS This is a briefer and clearer re-statement of the question I asked a couple of days ago.

[hosted-engine] install additional nodes without knowing another HE host's root password?
by Wee Sritippho 14 Mar '16

14 Mar '16

Hi, I'm trying to deploy a 2nd host to my hosted-engine environment, but the 1st host doesn't have a root password - it only has a sudo account. I can temporarily set a password and enable ssh for the root account, but I'm curious whether there is proper way to do this without messing with the user accounts? for example: - Locating the answer file that was copied from the 1st host manually (I already tried 'hosted-engine --deploy --config-append=answers-XXXXXXXXXXXXXX.conf' but the setup thought that I'm going to deploy my 1st host) - scp from an account other than 'root' Regards, Wee --- ซอฟต์แวร์ Avast แอนตี้ไวรัสตรวจสอบหาไวรัสจากอีเมลนี้แล้ว https://www.avast.com/antivirus

New install of hosted-engine using FibreChannel storage presenting Errors
by Paxton, Darren 14 Mar '16

14 Mar '16

Hi all Set up a brand new cluster with hosted-engine. Chose Fibre-Channel as the storage mechanism however on completion, running hosted-engine -vm-status I get the following; # hosted-engine --vm-status Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 117, in <module> if not status_checker.print_status(): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 60, in print_status all_host_stats = ha_cli.get_all_host_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 160, in get_all_host_stats return self.get_all_stats(self.StatModes.HOST) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 107, in get_all_stats stats = self._parse_stats(stats, mode) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 146, in _parse_stats md = metadata.parse_metadata_to_dict(host_id, data) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/metadata.py", line 156, in parse_metadata_to_dict constants.METADATA_FEATURE_VERSION)) ovirt_hosted_engine_ha.lib.exceptions.FatalMetadataError: Metadata version 5 from host 20 too new for this agent (highest compatible version: 1) This also results in adding a 2nd host failing due to a similar problem. I saw a previous post regarding iscsi storage resulting in similar errors but not FibreChannel. I can provide engine logs and such like if someone can guide me to what exact files to provide. I had cleared down the fibre-chaannel storage but do I need to wipe the devices fully before trying again? Thanks Darren

"wildcard resolve to multiple address" during hosted-engine --deploy
by Zach 14 Mar '16

14 Mar '16

I keep running into the following error when going through the "hosted-engine --deploy" configuration. [ ERROR ] Failed to execute stage 'Setup validation': wildcard resolved to multiple address So far, I haven't been able to figure out what I'm doing wrong. My best guess is that there is some issue with the FQDN that I used, but I'm not sure what I've done wrong. I've included the following line in /etc/hosts for the FQDN. 192.168.0.50 ovirt.domain.local I've also attached the output log, as well as the full output of me answering all the prompts. Any help would be appreciated, let me know if I need to include more information.

Know the console client IP from guest
by Simon Lévesuqe 13 Mar '16

13 Mar '16

From a windows guest (can be useful for linux guest as well), is it possible to get the IP of the spice client connected to console? I setup oVirt for a VDI. The users use thin clients that PXE boot using LTSP. I need the client IP to offer remote support via VNC. Now, I use epoptes as remote support tool, its an excellent peace of software but I need technicians from other branch of the company to be able to offer remote support to my users and they are all Windows guy ans don't want to connect to the LTSP server to start epoptes... They already use VNC to support Wyse type clients so I installed x11vnc on my clients chroot and setup it to start at boot. I know this is a security issue but this is the boss decision. Some client log to terminal servers using xfreerdp (LTSP clients boot directly to xfreerdp). In that case, everything is ok, we setup bginfo to print the client name and ip as they are windows environment variables. The problem is that many other clients boot to the oVirt user portal and users log to Windows 7 vm using Virt-Viewer and Spice. In bginfo, the only thing i can get is the IP of the Windows guest. It's ok, for most cases we can take control of the guest ant it do the trick but sometimes it's useful to vnc the thin itself. Thanks! Simon L

spacewalk integration
by Charles Kozler 13 Mar '16

13 Mar '16

Hi Guys - Can you use spacewalk as an external provider in oVirt? I see it allows Satelilte/Foreman but I know the new Satellite product is much different than Spacewalk as I believe Spacewalk is still technically Satellite 5 whereas Satellite 6 is an entire rewrite If Spacewalk can be used, what are some pre-reqs needed to get it working? Also, what are the benefits of using this? I was looking at it for the eratta information Thanks! -- *Charles Kozler* *Vice President, IT Operations* FIX Flyer, LLC 225 Broadway | Suite 1600 | New York, NY 10007 1-888-349-3593 http://www.fixflyer.com <http://fixflyer.com> NOTICE TO RECIPIENT: THIS E-MAIL IS MEANT ONLY FOR THE INTENDED RECIPIENT(S) OF THE TRANSMISSION, AND CONTAINS CONFIDENTIAL INFORMATION WHICH IS PROPRIETARY TO FIX FLYER LLC.

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

QEMU GlusterFS support in oVirt
by Samuli Heinonen 13 Mar '16

13 Mar '16

Hello all, It seems that oVirt 3.6 is still using FUSE to access GlusterFS storage domains instead of using QEMU driver (libgfapi). As far as I know libgfapi support should be available in Libvirt and QEMU packages provided in CentOS 7. Is there any workarounds how to use libgfapi with oVirt before it’s officially available? Best regards, Samuli Heinonen

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

Installation of host hangs and will not finish installation of host
by Jonas Kirk Pedersen 10 Mar '16

10 Mar '16

Im and quite new at using mailing list, but here is my current challenge. I am adding a new host from a fresh install centos 7. Updated with yum -y update and yum install then repo from ovirt v.3.6. Now the installation of the host is stuck at validating for 2 hours. Have tried to restart vdsmd to see if I cant trigger a failure, but no. Did a reboot of the host and that did not help. Now it is powered off and the engine is has registered that there is no connection to the host with error: "VDSM KVM2 command failed: Connection issue null" Is there a way to cancel a running task? -- Jonas Kirk Pedersen ASOM-Net Systemadministrator

The bumpy road to Ceph
by Bond, Darryl 10 Mar '16

10 Mar '16

We intend to migrate off our small Openstack/Ceph cluster to oVirt as it is a better fit for our organisation. We wanted to run oVirt backed on to Ceph storage for quite some time. We waited for the 3.6 development to take it's course and started testing last year. The kolla cinder container implementation changed fundamentally in the middle of the oVirt release process which broke the oVirt 'official' cinder implementation. We had tested oVirt using our Openstack cinder so we knew it basically worked but we didn't want to mix the oVirt and Openstack volumes, ie put oVirt into it's own ceph pool. We waited and waited for the Kolla container ... There didn't seem to be any end in sight, so we chose the following configuration: - Hosted engine on Centos 7.2 with gluster storage - Cinder/Keystone VM on Centos 7.2 using RDO and cinder 'liberty' kept in the same gluster store as the engine and managed by the engine. - Used the oVirt engine Postgres database as the Cinder/Keystone store so we didn't introduce more dependencies with MySQL that Kolla required. (New user and database for the cinder store. Backups exported separate to the engine backups) It's early days yet but here are some observations: - It works very well integrated with oVirt from the point of view of building and managing new VM's - Snapshots and cloning use ceph's features - No simple means to move Vm disks to and from other storage domains. - Not impossible though, it means that you have to delete and import ceph RBD's behind both oVirt and Cinder. It is fairly dangerous as I haven't found a simple way to get the rbd volume name with vdsClient other than 'vdsClient list' running VM's. Openstack at least publishes the volume name (UUID) in the gui, oVirt does not. - Successfully imported VM images from both Openstack and VMWare. - There is a hard dependency between oVirt and Cinder when starting VM's but does not require Cinder to run VMs. Strange really, when the volume name could be stored in oVirt when the volume is created rather than query cinder for each start. Where to from here. Hosting Cinder/Keystone in containers on the engine VM makes sense. We are going to roll our own container(s), given the data will be in the engine Postgres database it should be possible to transition in a clean fassion.

Fwd: Re: Slow after add 2 Nic

Hello, any help for using 2 nics in 2 networks? thx -------- Originalnachricht -------- Betreff: Re: [ovirt-users] Slow after add 2 Nic Datum: 2016-03-08 11:33 Von: Taste-Of-IT <kontakt(a)taste-of-it.de> An: oVirt Userlist <Users(a)ovirt.org> Hello, i simply add the nic and i think CentOS configure these by itself. Ok, i can change that. Short to my intentions. I want to use nic1 for my lan and nic2 for the wan route into the internet. in ovirt i want to install a firewall and configure both nics, nic for lan and nic2 for wan. in the other vm's i want to install only nic1 as bridge and configure the firwall as gateway which also service the dhcp. at all it must be safe that the vms cant break out of this and go around the firewall. so as i understand i would do this: - set in centos nic1 as default gatway wich has 192.168.0.1 as gateway - set in centos nic2 without default route - add in ovirt a new network / nic - create the vm for the firwall and assign nic1 and nic2 - in the other vms i would only assign nic1 is that the way to do or what do you think? thx Taste Am 2016-03-08 09:45, schrieb Yaniv Kaul: > Most likely (we've had something like that in FOSDEM) issue with DNS > resolving. > Make sure all IP addresses are correctly resolved. > Y. > > On Tue, Mar 8, 2016 at 12:44 AM, Taste-Of-IT <kontakt(a)taste-of-it.de> > wrote: > >> Hello, >> i have a question about adding a second Nic.

User cannot add a disk to a VM - permission error
by Will Dennis 09 Mar '16

09 Mar '16

Trying to understand the oVirt user permissions system… I have a user who I have granted the “PowerUserRole” role to, with the role description being “User Role, allowed to create VMs, Templates and Disks.” When I log into the User Portal with this user, I try to create a VM with a disk, but when I click the OK button, I get the message, “Cannot add Virtual Machine Disk. The user doesn’t have permissions to attach Disk Profile to the Disk. What other permission(s) do I need to grant this user in order to have it be able to create VMs?

HI I have configured two storage Lun through NFS one is Master which is having capacity of 2TB and the other is having 1TB. Now the issue when ever user deploy a vm automatically vm is getting deployed in master lun which is running out of HDD space and the vm is not getting deployed in the other Lun ,is there any setting to do that vm should get deployed in other LUN ?
