oVirt Live USB3 question

Sorry in advance if so. I have always bu= ilt out full blown multi rack instances of oVirt, and RHEV for clients, but= the following question has me wondering before I go digging and trying it = out... I realize that the oVirtLive ISO is for demo purposes, sandboxing, and not = production: I have a client, who is in need of a bootable AIO-based USB ins= tall with the caveat of being able to connect to the computer's HD and othe= r external storage at that point (for the Storage and ISO domains that I'll= create afterwards). This is because they have one BM to work with and the= y don't want the extra overhead using an SSD HD slot. They don't want to us= e a Sata DOM either if possible. In saying that, and concerning the oVirt LiveISO capabilities - I have two = questions. - Does the AIO USB install load necessary runtimes into memory, similar to = esxi bootable USBs and utilize the base hardware afterwards so that the res= t of the operations are ran in memory, hitting the disk (USB in this case) = like a normal OS load when needed for kernel calls, etc..?? - Are there a terrible performance costs if we stay with USB3 (which has a = ridiculous theoretical speed in certain hardware matching situations)?

Hot Memory add and Physical Memory guaranteed
by Luca 'remix_tj' Lorenzetto 26 Jun '17

26 Jun '17

Hello, i just tested the memory hot add to a vm. This vm had 2048 MB. I set the new memory to 2662 MB. I logged into the vm and i've seen that hasn't been any memory change, even if i said to the manager to apply memory expansion immediately. Memory shown by free -m is 1772 MB. Looking around i've found that that value was set in the option called "Physical Memory guaranteed". I tried setting this parameter to an higher value, but is still showing 1772, even if it says that "Memory" parameter will be changed immediately and minAllocatedMemory is changed at next boot. What is the right workflow to hot increase the ram of a vm?

Ovirt adding routes
by Alan Griffiths 26 Jun '17

26 Jun '17

Hi, When installing an ovirt host I got these routes automatically added default dev ovirtmgmt table 2886865805 scope link 172.18.19.128/26 via 172.18.19.141 dev ovirtmgmt table 2886865805 What is their intended purpose? It seems to be stopping packets from being correctly routed to the local gateway. Thanks, Alan

migrating VMS from old hosted engine to new hosted engine
by Paul Groeneweg | Pazion 26 Jun '17

26 Jun '17

We are moving our VMs from an old 3.6 oVirt platform to a new oVirt 4.1 platform. I am looking for an easy way to migrate the VMs. ( I know about export domain, but this takes 2 times a copy action ) I tested and just detaching the Data domain and attaching it, didn't work. Then I found the VM import option: - Adding a ssh key gen and setting password on virsh - load a list of machines in the webinterface from VM import - when I start an import the system complains: The following VMs retrieved from external server qemu+ssh://root@xxx.xxx.xxx.xxx/system are not in down status: VM [VM-NAME]. - I tried to suspend the VM, but this didn;t work either ( same error ) - Problem is ,when VM is shutdown, it disappears from this system list. Is there a way to directly import a VM from old oVirt platform to the new platform Looking forward to find a solution to quickly migrate our VMs. Best Regards, Paul Groeneweg

hi. i'm using ovirt version 4.0 . I've created two LUNs. firs lun is 2047GB and working properly as data domain. but when i try to add second lun as second data domain, i get this error on server: Jun 21 13:22:41 compute52 kernel: sd 12:0:0:16384: [sdf] Very big device.

hosted engine local disk estimate for OVA file
by Ben De Luca 25 Jun '17

25 Jun '17

Hi, I am in the middle of a disaster recovery situation trying to install ovirt 4.1 after a failure of some of our NFS systems. So I was redeploying 4.0 but there is a bug with the image uploader, that means I cant upload images. Our actually virtual machine hosts have very small HD's and the current 4.1 release installer thinks that the OVA extracted is 50GiB, I have exactly 50GB free! yay. So I did manage to hack the installer, to ignore my local disk space as the OVA is really only a few gigs in side. But its been pretty painful. Any chance of some one fixing the estimate there, I have read through the code, there was an attempt to find out the real size but they gave up and just guessed. -bd *tired sysadmin*

Info on live snapshot and agent interaction
by Gianluca Cecchi 23 Jun '17

23 Jun '17

Hello, supposing to have a Linux VM with ovirt-guest-agent installed, during a live snapshot operation it should be freeze of filesystems. Where to find confirmation of correct/successful interaction? /var/log/messages or agent log or other kind of files? Are there any limitations on filesystems that support freeze? Is it fsfreeze the command executed at VM OS level or any other low level command? Thanks, Gianluca

Frustration defines the deployment of Hosted Engine
by Vinícius Ferrão 23 Jun '17

23 Jun '17

Hello oVirt folks. I’m a traitor of the Xen movement and was looking for some good alternatives for XenServer hypervisors. I was aware of KVM for a long time but I was missing a more professional and appliance feeling of the product, and oVirt appears to deliver exactly what I’m looking for. Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal or better alternatives, but I’m starting to get frustrated with oVirt. Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my notebook, it was a no go. For whatever reasons I don’t know vdsmd.service and libvirtd failed to start. I make sure that I was running with EPT support enabled to achieve nested virtualization, but as I said: it was a no go. So I’ve decommissioned a XenServer machine that was in production just to try oVirt. The hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 48GB of system RAM, but I can’t get the hosted engine to work, it always insults my hardware: --- Hosted Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy. It’s definitely a problem on the storage subsystem, the error is just random, at this moment I’ve got: [ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response for JSON-RPC StorageDomain.detach request. But on other tries it came up with something like this: No response for JSON-RPC Volume.getSize request. I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so I’ve changed to an iSCSI backend, but the problem continues. This happens at the very end of the ovirt-hosted-engine-setup command, which leads me to believe that’s an oVirt issue. The OVA was already copied and deployed to the storage: [ INFO ] Starting vdsmd [ INFO ] Creating Volume Group [ INFO ] Creating Storage Domain [ INFO ] Creating Storage Pool [ INFO ] Connecting Storage Pool [ INFO ] Verifying sanlock lockspace initialization [ INFO ] Creating Image for 'hosted-engine.lockspace' ...

And the log file is too verborragic (hoping this word exists) to look for errors. Any guidance? Thanks, V.

Hello, I am using glusterfs as the storage backend for the VM images, volumes for oVirt consist of three bricks, is it still necessary to configure the arbiter to be on the safe side? or since the number of bricks is odd it will be done out of the box? Thanks in advance Cheers Erekle

problems migrating to hosted engine from bare metal
by cmc 22 Jun '17

22 Jun '17

Hi, I created a new host to deploy a hosted engine, and then used a backup from the bare metal engine and restored this, as per the procedure in: http://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Met… Everything worked fine up until step 15 ('Continue setup') as the script said the engine was not responding. I tried the reboot option (option 3), but still it would not connect. So I could not do the final step involving the internal CA, adding the host to an existing cluster (of which there were two other hosts). I was able to connect via vnc and ssh fine to the engine, and from here I could see that the ovirt-engine service was up. I had to install the aaa-ldap extension package to enable ldap auth separately however, but once done I was able to log in, and it showed the old cluster as it was on the bare metal engine. I added the host that I created the hosted engine on, and it installed various packages and then I configured the network and it looked fine, apart from the fact that I could not see a VM named 'HostedEngine' in the list of VMs. I think however that this was not a properly working setup, as the NFS storage I used to setup the hosted engine became unavailable and I think this killed the hosted engine, which caused it to reboot the host it was on. The hosted engine has not come back since then, so I'm guessing it either isn't properly set up for HA or it needs the NFS storage or something else was not properly done by me in the setup. I've restarted the bare metal engine for now as I needed it running for now. My questions are: 1. My understanding is that the NFS storage is initially used to create the hosted engine disk image, and is temporary, and that the hosted engine later gets migrated to the storage used by the rest of the cluster (which in my case is directly attached to the hosts via fibre channel). I suspect that this did not happen. The bare metal engine had some local ISO storage (on a hard disk local to it), which will not be replicated to the hosted engine VM - will this cause a problem for the deployment? I can create some new ISO storage later if not. 2. What is the recommended way to recover from this situation? Should I just run 'hosted-engine --deploy' again and try and find out what is going wrong at step 15? I can probably get the disk image that was on NFS and mount it to find out what went wrong on the initial deployment, or I can run the deployment again and then get the log when it fails at step 15. Ovirt version was 4.1.2.2 Thanks for any help, Cam
