yum mirrors 403 forbidden

I seem to be taking 2 steps back and 1 forward at the moment. What could I have done on a node to start getting 403 forbidden errors when using yum?

Can't migrate over migration network
by briandumont＠gmail.com 15 Apr '20

15 Apr '20

Hello, I am trying to configure a dedicated migration network and am unable to get it to work. It is failing with a no route to host error in the cockpit logs, specifically a libvirtd error virNetSocketNewConnectTCP:591 : unable to connect to server at '192.168.1.50:49152': No route to host. Trying to migrate from Host 1 to Host 2. 192.168.1.50 is the ip address on the source host for the migration. If I try to migrate in the other direction I get the same error with tthat hosts migration network ip. My migration network is setup on a different VLAN than my ovirtmgmt network. Here is my configuration: - 2 Hosts - Host 1 - nic 1 - ovirtmgmt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.50/24 VLAN 25 - Host 2 - nic 1 - ovirtmgmnt - 192.168.1.24/24 - VLAN 1 - nic 2 - migration network - 192.168.1.51/24 - VLAN 25 Migration network is setup as follows: - Assign - Yes - Required - Yes - VM Network - No (tried it with VM Nework = Yes with same results) - Migration Network - Yes I think I've got something fundamentally wrong with my host networking but I can't figure it out. Appreciate the help.

NUMA Pinning bug with Hugepages?
by Alan G 15 Apr '20

15 Apr '20

Hi, I seem to have found an issue when trying to setup a high performance VM utilising hugepages and NUMA pinning. The VM is configured for 32GB RAM and uses hugepages of size 1G. The host has two NUMA nodes each having 64GB RAM (for 128GB total system RAM). No other VMs are running or otherwise pinned to the host. The VM is pinned to node 0. And the required hugepages are allocated with echo 32 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages I then attempt to start the VM and get a pop-up error saying "cannot accommodate memory of VM's pinned virtual NUMA nodes within host's physical NUMA nodes". However, if I remove the hugepages from node 0 echo 0 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages Start the VM and then immediately re-create the hugepqages then everything works as expected. It seems to me that oVirt is considering the hugepages as allocated memory even if they are not in use. Is this correct? Thanks, Alan

upgrade VM cluster compatibility version
by Bill James 15 Apr '20

15 Apr '20

I'm trying to upgrade my cluster to 4.3. Currently its running 4.2.8.2-1.el7. But the cluster compatibility version is 3.6. I try to change that and it says I need to edit the VM. https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks.h… says: *Important:* An error message may warn that some virtual machines and templates are incorrectly configured. To fix this error, edit each virtual machine manually. The *Edit Virtual Machine* window provides additional validations and warnings that show what to correct. Sometimes the issue is automatically corrected and the virtual machine’s configuration just needs to be saved again. After editing each virtual machine, you will be able to change the cluster compatibility version. I edit the VM and there are no errors or warnings. I see no way to change the cluster compatibility level on a VM. How do I change the Custom Compatibility Version?? -- This email, its contents and attachments contain information from J2 Global, Inc. and/or its affiliates which may be privileged, confidential or otherwise protected from disclosure.

Get OAuth token locally without password?
by Chris Adams 14 Apr '20

14 Apr '20

I'm working on a cron job to run on the engine to do some tasks via the API. Is there a way I can get an API OAuth token created without actually storing a password? For example, some script that can be run to directly create a session in the database and return the token. Obviously this _can_ be done, it's a matter of knowing the right bits to do (so basically wondering if that has already been written). I only have internal users, so no external authentication store available. -- Chris Adams <cma(a)cmadams.net>

Migrate engine to another storage domain?
by Simon Nylund 14 Apr '20

14 Apr '20

Is there a successful way of migrating an up and running engine to another storage domain? I've been reading through the archive and tested a few various ways without any success. The only way i found working without errors was deploying a new engine attached to the new storage domain, and import the old data domain for the vms, but then you lose all the settings for the previous engine (ofc). And have to redo all of that.

Total LUN Limitations
by Ryan Chewning 13 Apr '20

13 Apr '20

I'm hoping that someone might be able to clarify a limitation found in the RedHat documentation. The documentation indicates that there is a limitation of 300 LUNS per block based storage device. Does this include LUNs which are directly mapped to a VM? Or does this referrer to LUNs which serve as a storage repository for ISOs / VM disks?

Host fails to enter in maintenance due to migration failure
by Vinícius Ferrão 13 Apr '20

13 Apr '20

Hello, I’ve a host that’s preparing to maintenance for almost 20 hours now. There’s a huge VM on it, with 32 gigs of RAM and this VM is failing migration. So, there’s a way to cancel prepare for maintenance, so the host can stop trying this migration that’s end up failing? I can just shutdown the VM to do the maintenance on the host... Thanks,
