by Florian Schmid 21 Mar '18

21 Mar '18

Hi, it looks like for this repo, the GPG key is expired. http://download.opensuse.org/repositories/home:/evilissimo:/ubuntu:/16.04/x… Does someone know, whom I should contact, that this key will be renewed? Or does someone know another repo, where I can download the latest ovirt-guest-agent for Ubuntu 16.04 BR Florian

--Apple-Mail=_2F3B6B23-5CA4-462A-87E0-5B084B91DCB9 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 Hi, I have 2-host oVirt setup with 2 Data Centers, one with local storage = domain (DC #1) for VMs + Export domain on NFS, another with all NFS = shared (DC #2). Trying to export VMs from DC #1 to DC #2. VMs are exported to DC #1 export domain (NFS), then domain put into = maintenance mode and detached from DC #1. Unfortunately, attaching it to DC #2 failed. Logs attached. Tried to run = this command twice. Workaround are possible in order to accomplish this task, yet it would = be better to do in a way as it was designed.

Fiber Channel Storage not coming up

Sizing hardware for hyperconverged with Gluster?
by Chris Adams 21 Mar '18

21 Mar '18

I have a reasonable feel for how to size hardware for an oVirt cluster with external storage (our current setups all use iSCSI to talk to a SAN). I'm looking at a hyperconverged oVirt+Gluster setup; are there guides for figuring out the additional Gluster resource requirements? I assume I need to allow for additional CPU and RAM, I just don't know how to size it (based on I/O I guess?). -- Chris Adams <cma(a)cmadams.net>

How to deal with "Used memory of host ... exceeded defined threshold [95%]" messages
by Klaas Demter 21 Mar '18

21 Mar '18

Hi, I'm trying to figure out how I could stop the manager with spamming used memory exceeded threshold messages. I have a hypervisor that has 1,5TB memory and it's using about 98% of that with hugepages for sap hana vms (configured like https://access.redhat.com/articles/3347431) It still has like 40-50GB memory left for the hypervisor which should be plenty. So the option I could figure out on my own: I can adjust the global limit of LogMaxPhysicalMemoryUsedThresholdInPercentage but I'm not sure if that is a good idea for my "normal" hypervisors that often have way less memory. My questions are: - can I adjust the limit on a per hypervisor basis? - can I skip the memory check for certain hypervisors or skip all checks for certain hypervisors? - would a check for free memory in gb make more sense than a percentage check? Setup is still on 4.1.9. Greetings Klaas

Re: [ovirt-users] Change ovirtmgmt ip from dhcp to static in a
by Michael Burman 21 Mar '18

21 Mar '18

Indeed very odd, this shouldn't behave this way, just tested it my self and it is working as expected. Unless i miss understood you here, do you use a different IP address when switching to static or the same IP that you got from dhcp? if yes, then this is another flow.. Can you please share the vdsm version and vdsm log with us? Edy, any idea what can cause this?
