3.6 upgrade issue
by Jon Archer 01 May '16

01 May '16

Hi all, Wonder if anyone can shed any light on an error i'm seeing while running engine-setup. If just upgraded the packages to the latest 3.6 ones today (from 3.5), run engine-setup, answered the questions, confirming install then get presented with: [ INFO ] Cleaning async tasks and compensations [ INFO ] Unlocking existing entities [ INFO ] Checking the Engine database consistency [ INFO ] Stage: Transaction setup [ INFO ] Stopping engine service [ INFO ] Stopping ovirt-fence-kdump-listener service [ INFO ] Stopping websocket-proxy service [ INFO ] Stage: Misc configuration [ INFO ] Stage: Package installation [ INFO ] Stage: Misc configuration [ ERROR ] Failed to execute stage 'Misc configuration': function getdwhhistorytimekeepingbyvarname(unknown) does not exist LINE 2: select * from GetDwhHistoryTimekeepingByVarName( ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts.

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

python floppy in RunOnce mode
by Giulio Casella 07 Jan '16

07 Jan '16

Hi, I'm trying to boot a vm with non persistent floppy using python ovirt sdk (the "RunOnce" way in administrator portal), but guest OS can't see floppy drive. The ultimate goal is to deploy floppy with sysprep unattend.xml file for windows 7 pools of vm. Here is a snippet of code I use: ------------------------------------------------- myvm = api.vms.get(name="vmname") content="This is file content!" f=params.File(name="foobar.txt",content=content) fs=params.Files() fs.add_file(f) payload=params.Payload() payload.set_type("floppy") payload.set_files(fs) payloads=params.Payloads() payloads.add_payload(payload) thevm=params.VM() thevm.set_payloads(payloads) action=params.Action(vm=thevm) myvm.start(action=action) xml = ParseHelper.toXml(action) print xml ------------------------------------------------- As you can see, for debugging purpose, I print my xml action, and I get: ------------------------------------------------- <action> <vm> <payloads> <payload type="floppy"> <files> <file> <name>foobar.txt</name> <content>This is file content</content> </file> </files> </payload> </payloads> </vm> </action> ------------------------------------------------- in the admin portal I can see my vm in "RunOnce" state, but no floppy is present... In fact in the vm process command line (ps -ef | grep qemu-kvm | grep vmname) I can't see -drive option referring to floppy (I only see 2 "-drive" options, referring to vm system disk and to a correctly mounted cdrom ISO) What I'm doing wrong? (The engine is RHEV-M version 3.4.1-0.31.el6ev) Thanks in advance, Giulio

First off, I didn't have my deploying-host hostname in the hosts map for my engine. After adding it to /etc/hosts (both hostname and FQDN), when I try to ssh from root@engine to root@host it is prompting me for a password. On my engine, ~root/.ssh does not contain any keys. On my host, ~root/.ssh has authorized_keys, and in it there is a key with the comment "ovirt-engine". It's possible that I inadvertently removed ~root/.ssh on engine while I was preparing the engine (I started to set up my own no-password logins and then thought better and cleaned up, not realizing that some prior setup affecting that directory had occurred). That would explain the second issue. How/when does the key for root@engine get populated to the host's ~root/.ssh/authenticated_keys during setup? -Bob > >> -Bob >> >>> Till hosted-engine hosts were simply identified by their IP address but >> than we had some bug report on side effects of that. >>> So now we generate and sign certs using host hostnames and so the engine >> should be able to correctly resolve them. >>>> When I log into the Administration portal, the engine VM does not appear >>>> under the Virtual machine view (it's empty). >>> It's cause the setup didn't complete. >>> >>>> I've attached what I think are the relevant logs. >>>> >>>> Also, when my host reboots, the ovirt-ha-broker and ovirt-ha-agent >> services >>>> do not come up automatically.

Issue with kernel 2.6.32-573.3.1.el6.x86_64?
by Michael Kleinpaste 30 Nov '15

30 Nov '15

So I patched my vhosts and updated the kernel to 2.6.32-573.3.1.el6.x86_64. Afterwards the networking became unstable for my vyatta firewall vm. Lots of packet loss and out of order packets (based on my tshark at the time).

+1 to iso upload from gui +1 to ceph support (if the way is via Cynder, then integrate Cynder in Ovirt as you did with neutron to get arround the lack of features in networking) I've been asking for several things (with their respective RFEs) and as versions go by without success, I'm asking again: - 1049994 [RFE] Allow choosing network interface for gluster domain traffic - 1049476 [RFE] Mix untagged and tagged Logical Networks on the same NIC - 1029489 [RFE] Export not exporting direct lun disk - 1051002 [RFE] ISO domain should be a simple NFS share containing ISOs

Can´t use a VM Network VLAN, because the Virtual Machines inside can't reach the Gateway
by Julián Tete 23 Oct '15

23 Oct '15

Hi Friends of oVirt I'm trying to migrate my company from VMware to oVirt. In my final tests, I set up 2 more VLANs in oVirt, (VM VLANs) The Virtual Machines in these VLANs, can be reached from the external IPs from the net range, but from the Virtual machines only can ping the Host with the Bridge and itself, can't reach the gateway. ¿? I configured a IP Forwarding in the Host with the virtual machine, and nothing changes... Any idea ? This is the last duty before embrace oVirt in the company. Look to the VLAN 100 configuration (My desired VM Network): http://postimg.org/image/7hrog0a2n/ http://postimg.org/image/68b40i1vr/ http://postimg.org/image/lu6mlshgp/ http://postimg.org/image/540o1qc0t/ http://postimg.org/image/4kyg787bt/ http://postimg.org/image/v7ralh7zb/ http://postimg.org/image/kn903cl03/ For any idea, thanks in advance

Backup storage domain for the meta data ONLY?
by Nicolas Ecarnot 21 Oct '15

21 Oct '15

Hi, In a lab, I have an oVirt test datacenter using a very old SAN (iSCSI setup). There are very few VM on it, and none of them are in critical. Some risky maintenance is to be planned on the SAN, and the risk is to lose it all. To be honnest, to lose these VMs is bearable, but to lose the setup would be painful (quite long to set everything back up). This is not an hosted setup, so I guess most of the config lies in the manager, and this part will stay untouched. My question : Is there any benefit to add an small additionnal temporary storage domain where (some unknown by me) meta datas could be duplicated (knowing that I have not enough room to export the VM)? What additionnal setup would be saved this way? -- Nicolas ECARNOT
