vGPU
by 董青龙
Hi all,
I am testing vGPU in ovirt4.2. I have a nvidia p100 GPU installed in the host and I have installed the correct dirver. I followed this page(https://www.ovirt.org/documentation/install-guide/appe-Preparing_a_H... but I failed. In the "Host Devices tab" I got an device called "GP100GL [Tesla P100 PCIe 16GB]". I could not find any device of "mdev type". Anyone can help me? Thanks a lot!

you can use the persisted libvirt definition on host where it was running last if the host just crashed (it’s removed on clean guest shutdown though). If you have it you can connect the appropriate storage domain using vdsm-client, and then start the VM using that libvirt definition.
again, it’s not very easy to do.
In all other cases it would have to be generated by the engine again as the OVF_STORE OVF backup is an OVF and you need libvirt’s XML so you would have to convert it first anyway, so again nothing simple to do.
In disaster recovery scenrio you can just take the whole storage domain and import it into the new clean engine installation and you’ll get all the VMs
it depends what you really want to do
Thanks,

Cloud-init reset network configuration to default dhcp after reboot and regular run
by Mike Lykov
Hi All!
I'm trying to configure network in VMs created from template, and see
strange behaviour from cloud-init.
cloud-init installed and enabled in template.
ver cloud-init-0.7.9-24.el7.centos.1.x86_64
guest Centos 7.5
ovirt 4.2.7 from ovirt-releases-42-pre repo
1. I use "run once" with initial run - use cloud-init - networks
in-guest net iface : eth0
add new - static
enter address, mask, gw
ipv6 none
Run (once) and cloud-init configure ifcfg-eth0 for that address
(successfully).
2. I shutdown that VM and use "Run" (regular) without "use cloud init"
in VM properties, awaiting that above configurations are saved (and
booted with it).
But because "use cloud init" not checked, and cloud-init service
enabled, it start, cannot find datasource and drop configuration to
default (dhcp).
In cloud-init.log
2018-11-20 13:53:24,153 - util.py[WARNING]: No instance datasource
found! Likely bad things to come!
2018-11-20 13:53:24,153 - util.py[DEBUG]: No instance datasource found!

It reverts config as in here

3. then I found bug

and when "run once" I disable network config as in that comment.
Shutdown, Run (not once) and voila! Ip address are static!

"cloud-init used to use a "marker" file that it created on initial

- are it not working in ovirt/this cloud-init version ?

Additional routes on Interface
by Sandro Emma
Hi,
we are running a RHV 4.1 installation which is working fine except one issue:
We have a Network which is only used for fencing(power Management via ilo), each host has an interface with this network and a custom ip, for this to work we need a few custom routes.
At the moment we add the new routes via a plain route file under /etc/sysconfig/network-scripts/, but the engine flags this interface then as out-of-sync.
How can we persist those changes across reboots and still be able to add new devices via the UI ?
This looked promising but isnt working: https://ovirt.org/develop/release-management/features/network/networkrelo...
Thanks for any Help :)

I deleted the 'pre' repos several times but apparently they are being recreated somehow.
Can anybody explain this behaviour please and eventually the meaning of these 'pre' repos in generell as well?
Thank you in advance.

The built in group Everyone is troublesome.
by Jacob Green
So all my VMs are inheriting system permissions from group
everyone and giving all my users access to all my VMs, in ovirt 4.2. Is
there a best practices guide or any recommendation on how to clear this
up? Clicking remove on everyone does not work because Ovirt won't allow
me to remove a built in account.
Thank you
