Did you read a bit about oVirt and understand its architecture? What hosted-engine is? You probably need to disable MAC filtering on your host. No idea how to do that in "Virtual Machine Manager". You have: 1. Your physical machine/host 2. A VM inside it acting as an oVirt host, with its MAC address (assigned by the virt software on the host) 3. A vm inside that one, so-called the hosted-engine VM, with its own MAC address (assigned by the hosted-engine deployment process). When (3.) tries to access (1.) (either directly, or the outside world through it), (1.) sees the traffic on the vnic of (2.), but with a MAC address different from (2.)'s. So it might block it. That's just a guess - I don't know archlinux's "Virtual Machine Manager". If you are doing this for studying, and do not have a spare physical machine for doing the hosted-engine install on, it might be better to first try standalone (non-hosted-engine) setup. It will be more work, and require you to learn more, but will hopefully be easier to understand and debug if something goes wrong.

[ovirt-users] Re: new hyperconverged setup
You are using NVMEs, so you can safely use JBOD mode. I think that the size should be for a single disk, but you can experiment on that. If the LVs are too small, you can just extend them or even recreate them. What is you network speed ? If your network bandwidth matches your NVMEs' combined Read speed - then avoid dedup and compression unless you really need them. Most probably your NVMEs have a 4096 sector size . If yes, you will need vdo with '--emulate512'. Yet, tuning VDO for such fast devices is not a trivial task. Most probably you can configure a VDO per each NVME (or even per pertition/lv) , and configure it with compression and dedup disabled (emulate512 only if needed). Also check the UDS index topic, as it is quite important: https://access.redhat.com/documentation/en_us/red_hat_enterprise_linux/7/html/storage_administration_guide/vdo-ig-administering-vdo#vdo-ig-config-uds-index If your network is slower than your disks, you can enable dedup and compression. Also gluster has a setting called 'cluster.choose-local' . You can enable it in order to tell the FUSE driver to prefer local brick instead those over the network.

Actually I have to dig the mailing list, cause I can't remmember the exact steps and if you miss something - everything can go wild. I have the vague feeling that I just copied the data inside the volume and then I just renamed the master directories . There is a catch - oVirt is not very smart and it doesn't expect any foreign data to reside there. Of course, I could survive the downtime.

[ovirt-users] Re: new hyperconverged setup
Ok yeah that is fairly similar to my setup, except I only have two drives in each host. In my case I created completely separate data volume, one per drive. You could do the same, three data volumes for storage @ 7TB each for example. On one of the volumes you'll need to split off 100Gb volume for engine, So you'd end up with something like 2 x 7Tb data volumes, 100Gb engine and 6.9TB data volume or something along those lines. With multiple non-raided drives I'm not sure if this is the best approach or if it makes more sense to software raid the drives first. Personally I like the fact that my volumes are separated.

I have two ssds in each host for storage. I ended up using the wizard but in the wizard I simply added two data volumes Ex: storage1 = /dev/sda storage2 = /dev/sdb You can create as many storage volumes as you want. You don’t need to have just one single large volume. You could have just one big volume but I believe you’d need either hardware or software raid to accomplish that.

Hi, if I can ask some other info, probably I find a "ghost disk" related to previous problem. Infact, I still cannot remove the broken template, because its disk is still registered somewhere; can You please suggest me where to search for it?

[ovirt-users] new hyperconverged setup
I am about to setup a new hyperconverged setup with the following 3 host setup 2 x nvme 240gb hd for OS on each host (raid) 3 x nvme 7 tb hd for vm storage on each host (no raid card) 500gb RAM per each host I am confused during the gluster setup portion using the web ui setup wizard. When asked for the LV size do I input the maximum size of the hard drive on a single host or do I combine the total capacity of the matching hard drives on all 3 host? Example that I would be putting in is hard drive: /dev/nvme1p1 capacity 7tb or should it be 21tb (combined capacity of the matching single HD on the other host). Or is there a better method you recommend? And since I am using nvme hard drive would you recommend using dedup and compression or no?

These are the available statuses[1], you can change it to 0, assuming the VM is down [1] https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/common/src/main/java/org/ovirt/engine/core/common/businessentities/VMStatus.java#L10 On Wed, Dec 2, 2020 at 12:57 PM <3c.moni...@gruppofilippetti.it> wrote: > Hi. > It's correct. > But how unlock / change / remove it? > In the same table, a lot of fields are empty, "0" or NULL. > Only vm_guid and status have a value. > Thanks, > M. > ___ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/PIZ7TQV46L3FBOV6PTNMTWQ2O7CF5EGX/ > ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/AD3SUCPR2TR73VXTINI522M5BDTJ56FU/

I am not sure what is locked? If everything in the images table is 1, then the disks are not locked.

Hi Patrick, I checked the cockpit-ovirt code, and it seems you are right. Ansible changed the module's behavior in the 2.9.14 version and the module no longer returns 'ansible_facts'. I believe [1] should fix that, but I didn't check it yet. Can you please provide the ovirt-hosted-engine-setup log files and ansible version?
