[ovirt-users] high load on hosts

I'm wondering how I can best limit the ability of VMs to overrun the load on hosts. I have a fairly stock 4.2 HCI setup with three well spec'ed servers, 10Gbe/SSDs, plenty of ram and CPU with only a hand full of light use VMs. I notice when the occasional demanding job is run on a VM I'm seeing

It looks to me like a fairly obvious ssh problem. Are the ssh keys setup for root user and permitrootlogin yes in Asheville config? On Thu, Oct 25, 2018, 7:29 AM Jarosław Prokopowski, wrote: > Hi, > > Please help! :-) I couldn't find any solution via google. > > I followed this document to

You should also make sure the host can ssh to itself and accept keys On Thu, Oct 25, 2018, 8:42 AM Jayme, wrote: > Darn autocorrect, sshd config rather > > On Thu, Oct 25, 2018, 7:29 AM Jarosław Prokopowski, < > jprokopow...@gmail.com> wrote: > >> Hi, >> >&g

[ovirt-users] Re: Configuring Ovirt + ACPI

With dell servers for example it's as simple as editing the host and enabling power management then selecting the appropriate drac version and entering login details. I'm not familiar with what supermicro uses for remote management but there is likely an option there to support it On Mon, Nov 5,

Tony, is there a reason why you wouldn't just do a three more hyper converged setup with self hosted engine? This is the best option for a three server setup imo On Tue, Nov 6, 2018, 8:37 AM Tony Brian Albers Hi guys, > > I have 3 machines that I'd like to test oVirt/gluster on. > > The idea is

Is it possible to update oVirt HCI environment automatically with ansible? If so are there any specific instructions or details on the process? Thanks! ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org

[ovirt-users] troubleshooting node upgrade failures

I have a very standard three node HCI setup running the latest version of oVirt 4.2. I've been having some problems updating hosts, the last update that was released a few weeks ago would produce installfailed when updating hosts. I was able to resolve this by rebooting the host first then

[ovirt-users] Re: Ansible upgrade procedures?

leaving the others untouched. could it be because after the first host comes up from a reboot the gluster healing prevents the other host statuses from being "up" thus ansible skips over them? On Wed, Nov 14, 2018 at 11:49 AM Martin Perina wrote: > Hi Jayme, > > you can upgrad

You should be using shared external storage or glusterfs, if gluster you should have other drives in the server to porvision as gluster bricks during the hyoerconverged deployment On Mon, Oct 8, 2018, 8:07 AM Stefano Danzi, wrote: > Hi! It's the frist time thai I use node. > > I installed node

I've been seeing these warnings myself, on 1Gb ovirtmanagement (glusterFS is 10Gbe backend). I haven't correlated to network graphs yet but I don't know what would be happening on my management network that would be exhausting 1Gb network. On Fri, Aug 31, 2018 at 3:27 AM Florian Schmid wrote:

[ovirt-users] Re: Hosted Engine Upgrades

Upgrading the engine is fairly straight forward. What I do is place the cluster in global maintenance mode. Then on the engine vm yum update Ovirt packages then run engine-upgrade. After upgrade I do a general yum update on engine vm to update other non Ovirt packages On Thu, Sep 20, 2018,
