Bongiorno Gianluca, I am entering the data in bugzilla right now... Logs: There is a problem, I have not found any log evidence of this export and import, I don't even know which component is actually doing this. For 'foreign' imports like VMware and other *.vmdk producing hypervisors, VDSM

[ovirt-users] OVA export creates empty and unusable images

2020-07-30 Thread thomas
I've tested this now in three distinct farms with CentOS7.8 and the latest oVirt 4.3 release: OVA export files only contain an XML header and then lots of zeros where the disk images should be. Where an 'ls -l .ova' shows a file about the size of the disk, 'du -h .ova' shows mere kilobytes,

Sorry Strahil, that I didn't get back to you on this... I dare not repeat the exercise, because I have no idea if I'll get out of such a complete break-down again cleanly. Since I don't have duplicate physical infrastructure to just test this behavior, I was going to use a big machine to run a

I might have run into similar issues at one point... And it might be where the network configuration on the installation host has already been partially changed to include the bridge that's used to communicate with HostedEngineLocal. The installation is not able to pick up cleanly from every

[ovirt-users] Re: OVA import does not upload disks

2020-07-29 Thread thomas
I have the same issue, it seems, but AFAIK the problem is on the export side: While the OVA logical file size matches the size of the VM's disk, the actual storage usage on the VDO compressed and deduplicated NFS I use as export target per 'du -h *.ova' is a mere 28KB, while 'strings .ova'

Hi Damien, I'm afraid nobody will be able to help you here. What made the CPU jump into a sea of "FF FF FF FF..." can't be diagnosed remotely, but it's KVM that stopped, because that's not legal x86-64 code, nothing oVirt can do about it. Salut Damien, j'ai bien peur que personne ne puisse

2020-07-29 Thread thomas
I honestly don't know, because I have not tried myself, so you might just want to stop reading right here. But from what I understand about the design philosophy of oVirt, it should be ok to change it, while nobody probably ever tested it and everybody would tell you it's a bad idea to do so,

[ovirt-users] Re: where is error log for OVA import

2020-07-29 Thread thomas
From what I have observed, OVA import seems to have two modes: If the OVA is a 'foreign' format, the ova file needs to be converted and that conversion effort is then logged into /var/log/vdsm/import on the oVirt node where in import runs. Import failures are then mostly an issue with the

I tried using nested virtualization, too, a couple of weeks ago. I was using a 3 node HCI CentOS 7.8 cluster and I got pretty far. Configuring KVM to work with nested page tables isn't all that well documented but I got there, I even installed some host extensions, that seem requried. Even the

[ovirt-users] OVA exported from oVirt cannot be imported in oVirt

2020-07-29 Thread thomas
I have successfully imported OVA files which came from VirtualBox before, something I'd consider the slightly greater hurdle. Exporting a VM to an OVA file and then importing it on another platform can obviously create compatibility issues, but oVirt <-> oVirt exports and imports with the same

Not sure I understand your interest for an older repo. I am still regularly doing ovirt 4.3 installs just by not chosing the 4.4 repo, which is exclusively CentOS 8 (while 4.3 is exclusively CentOS 7: You cannot mix). Here is my current ovirt-4.3.repo: [root@ yum.repos.d]# more ovirt-4.3.repo

I'd say you were close! I tried fiddling with the penalties, but that didn't do anything good. But once I found that hosted-engine --vm-status displayed the score across the hosts, I found them to be very low constantly, the 1600 gateway penalty seems a proper match. I then reinstalled the

Running a couple of oVirt clusters on left-over hardware in an R niche of the data center. Lots of switches/proxies still at 100Mbit and just checking for updates via 'yum update' can take awhile, even time out 2 times of out 3. The network between the nodes is 10Gbit though, faster than any

Ciao Sandro, just tried to re-install a Centos7 based HCI cluster because it had moved to another network. And from what I can tell it fails because Gobinda Das introduced a hot-fix into 'gluster-ansible-infra/roles/backend_setup/tasks/vdo_create.yml' that adds a '--maxDiscardSize 16M' option
