by kevin.doyle＠manchester.ac.uk 02 Aug '19

HI I think it is a bug with qemu, and isci disks. Has anyone else seen this issue VM crashes and lost communication with qemu Can I update qemu ? if so what is the latest support version to use on Ovirt 4.3.2.1-1.el7 Current versions of qemu installed Installed Packages qemu-img-ev.x86_64 10:2.12.0-18.el7_6.3.1 qemu-kvm-common-ev.x86_64 10:2.12.0-18.el7_6.3.1 qemu-kvm-ev.x86_64 10:2.12.0-18.el7_6.3.1 Many thanks Kevin

Use public-signed SSL certs?
by Chris Adams 02 Aug '19

02 Aug '19

I installed an SSL cert from a public CA (Let's Encrypt) on my engine, following this: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/ht… That gets the regular web UI working, but I can't upload an ISO. I assume that I need to do something with the imageio-proxy service on the engine, but not sure what... I tried replacing imageio-proxy.cer and imageio-proxy.key.nopass, but that didn't work. I'm trying to avoid ever needing to install a special CA cert in browsers. -- Chris Adams <cma(a)cmadams.net>

Re: Manual Migration not working and Dashboard broken after 4.3.4 update
by Strahil 02 Aug '19

I'm not sure, but I always thought that you need an agent for live migrations. You can always try installing either qemu-guest-agent or ovirt-guest-agent and check if live migration between hosts is possible. Have you set the new cluster/dc version ?

no network interface
by A S 01 Aug '19

01 Aug '19

Hi. I had ovirt running with a VM but it suddenly broke. I wiped it all and did a reinstall but now I am not able to connect my host to the network. the host is always saying status='unassigned'. in the network page where I would drag and drop a connection, there is no interface to connect to. its this page https://ovirt.org/images/wiki/SetupNetworksNew.png?1478101462 but there is nothing in the interfaces column on the left Can anyone point me in the right direction to fix this? Thanks I have only one machine with the engine and host on it.

Trouble initializing new VM in 4.2.8.2-1.el7
by David Johnson 30 Jul '19

30 Jul '19

Good evening, Thanks in advance, I'm trying to set up a new VM in my cluster, and things appear to have hung up initializing the 80GB boot partition for a new Windows VM. The system has been sitting like this for 6 hours. What am I looking for to resolve this issue? Can I kill this process safely and start over?

Moving data to new storage appliance
by David Johnson 30 Jul '19

30 Jul '19

Hi everyone, I'm sorry to bother y'all with another noob question. We are in the process of retiring the old storage appliance that backed our oVirt cluster in favor of a new appliance. I have migrated all of the active VM storage to the new appliance, but can't see how to migrate the "base versions". My understanding is that if I just drop the storage with the base versions then the derived VM's will cease to be functional. Please advise.
