Installing over Cockpit Gluster deployment HC:
"FQDN is not reachable"
And of course it is! All interfaces are pingable and accessible over SSH without problems.
I am accessing Cockpit from a 4rth, public IP, from a remote computer. So the client browser is remote, and the Cockpit is accessed from a public IP address. Is that the problem?
Is there a way to do the 3 node HC from the command line? I see no other error than that, where are the actual logs?
I've got a single physical host and it's isolated and I don't have access to other hosts or share storage.
Is it possible to use my host local storage as shared storage for my hosted-engine setup?
Sharing a directory like /var/ovirt-storage with NFS. What about iSCSI?
Thank you in advance
I only have one physical server and it's isolated and doesn't have access to other hosts ( I can't get any shared storage from other systems or storage)
Is it possible to use NFS to share my physical host storage (ex. /var/ovirt-storage) to the self-hosted engine during set up?
I have a VM with 2003 server x64, and I upload the vm image to oVirt.
The VM boot on the oVirt, but, the blue screen appear with a error message:
Anybody has some information about this?
I try to convert de img file from raw to qcow2, but the error persists.
if I create a VM and select Q35 machine type, still the General --> create
image option in edit phase doesn't show sata as an option.
Even if I create the VM without disks and then go to edit General -->
create, I only see IDE, VirtIO-SCSI and VirtIO.
Instead if I click VM name, DIsks --> New, I can select VirtIO-SCSI, VirtIO
After the first disk (SATA in my case) has been created, now if I go and
edit VM --> General --> Instance Images + --> Create, I see consistent
I think GUI experience could be improved.
Also because I can reproduce this workflow converging to an error (even if
IDE disks are not so common nowadays...):
In general I create an IDE disk
In System I select in Advanced parameters, Custom Chipset/Firmware Type Q35
(EFI or BIOS based)
At the final OK I get the error:
Cannot add Virtual Disk: The disk interface is not supported by the VM OS:
The result is VM created but without the IDE disk as not supported in Q35
Tested in 4.4.4
We have a strange thing, which not clear to us.
When provisioning a new VM via REST API, if the number of vCPU for that VM is more than 16, I'm getting this error:
Fault reason is "Operation Failed". Fault detail is "[Cannot add VM. Maximum number of threads per cpu exceeded]". HTTP response code is 409.
Our version is: Version 18.104.22.168-1.0.9.el7
Note that manual provisioning from the UI do not produce any error when using vCPU > 16.
It seems like the issue is related to this setting (from the engine):
[root@olvmengine01 ~]# engine-config -g MaxNumOfThreadsPerCpu
MaxNumOfThreadsPerCpu: 8 version: 4.1
MaxNumOfThreadsPerCpu: 8 version: 4.2
MaxNumOfThreadsPerCpu: 8 version: 4.3
But when trying to set it to another number, I'm always get this error, for example:
[root@olvmengine01 ~]# engine-config -s MaxNumOfThreadsPerCpu=10
Please select a version:
Cannot set value 10 to key MaxNumOfThreadsPerCpu.
1. Can you please explain why we getting this error: "Cannot add VM. Maximum number of threads per cpu exceeded"?
2. Is it related to engine-config -g MaxNumOfThreadsPerCpu?
3. Why it is working manually via the UI?
4. if its related to engine-config, why we can't set it to another number?
Thanks in advance,
We're running oVirt 4.1.8. We make an intense use of the VM Portal, as
our students use it to access and handle their machines. We're currently
having an issue with just one of our users. He claims that he created a
VM, and when tried to edit its details (clicking on the pencil), a
screen stating that the "VM Portal is experiencing some issues" is shown
I granted a UserRole permission on a user I handle, and I don't
experience that problem, I can edit the VM with no issues. The user also
states that this happens on any VM he creates.
I see nothing relevant in the log regarding this issue.
Please, any hint how to debug this?
I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right?
Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)!
Also I know with doing that I'm totally on my own etcetera
I've one server ovirt-engine. I've trois nodes glusterfs on this ovirt-engine. Ex: ovirt-engine : ovirt-node1, ovirt-node2 and ovirt-node3.
Now, I want add ovirt-node4. I tried with "Deploying oVirt and Gluster Hyperconverged". But it propose only trois nodes.
Could you help me, please ?
