Changing ticket duration for VMs
by Alexis HAUSER
Hi,
I'm looking for a way to change the duration of all tickets from all VMs. How can I do this ? I'd like to change it to 5 min instead of 2 min.
It seems it is possible to change these parameters using the RestAPI, with "action.grace_period.expiry" or "action.ticket.value"...
Anyway, these parameters seems to be accessible only using POST but not GET. How can you retrieve their value then, using POST ?
These parameters seem to be available for each VM, is there a way to set it for all VMs in general, even next VM created ? Do they work for all tickets created, or only one single generated ticket where you define its value ?

strange API parameters default in python SDK
by Fabrice Bacchella
When I'm looking the RHEV's documentation about the API class in the python SDK, I see :
persistent_auth
Specifies whether persistent authentication is enabled for this connection. Valid values are True and False. This parameter is optional and defaults to False.
filter
Specifies whether or not user permission based filter is on or off. Valid values are True and False. If the filter parameter is set to False - which is the default - then the authentication credentials provided must be those of an administrative user. If the filter parameter is set to True then any user can be used and the Manager will filter the actions available to the user based on their permissions.
I'm surprised, because in my mind, the default value are the least usefull version of each options. Why don't set them to good, useful values and let the user changed them to the opposite if there is some problems ?

qemu cgroup_controllers
by Дмитрий Глушенок
Hello!
Is it possible to tell libvirt to add specific devices to qemu cgroup? By somehow enumerating the devices in XML using a hook for example.
I'm passing scsi-generic disks (/dev/sgX) to VM using qemucmdline hook and it doesn't work until I remove "devices" from cgroup_controllers in qemu.conf.

Getting SPICE connection parameters with Python-SDK
by nicolas＠devels.es
Hi,
On user portal, when users click on the "Connect" link of a VM that is
configured to be run with "Native client" and SPICE protocol, a .vv file
is generated with the connection parameters so the SPICE client knows
where to connect: host, port, password, ...
Currently, is there a way to generate those parameters with the Python
SDK? Especially the session password so it's possible to connect to the
VM directly with a SPICE client.
Thanks.

Ovirt system reboot no symlink to storage
by David Gossage
This morning I updated my gluster version to 3.7.11 and during this I
shutdown ovirt completely and all VM's. On bringing them back up ovirt
seems to have not recreated symlinks to gluster storage
Before VM's were created and the path they expected to find the storage at
as it was created by oVirt was
/rhev/data-center/00000001-0001-0001-0001-0000000000b8/7c73a8dd-a72e-4556-ac88-7f6813131e64
which was a symlink to what was mounted
at /rhev/data-center/mnt/glusterSD/ccgl1.gl.local:GLUSTER1 once engine
activated hosts
It never seemed to recreate that symlink though and I ended up just doing
so manually and after that I could bring up my VM's.
If this was caused by some error would I likely find that in the engine
log's on the engine vm or on one of the vdsm logs of a host?
I'm running oVirt Engine Version: 3.6.1.3-1.el7.centos

Questions on oVirt
by Brett I. Holcomb
After using oVirt for about three months I have some questions that
really haven't been answered in any of the documentation, posts, or
found in searching. Or maybe more correctly I've found some answers
but am trying to put the pieces I've found together.
My setup is one physical host that used to run VMware ESXi6 and it
handled running the VMs on an iSCSI LUN on a Synology 3615xs unit. I
have one physical Windows workstation and all the servers, DNS, DHCP,
file, etc. are VMs. The VMs are on an iSCSI LUN on the Synology.
* Hosted-engine deployment - Run Engine as a VM. This has the
advantage of using one machine for host and running the Engine as a VM
but what are the cons of it?
* Can I run the Engine on the host that will run the VMs without
running it on a VM? That is I install the OS on my physical box,
install Engine, then setup datastores (iSCSI LUN), networking etc.
* How do I run more than one Engine. With just one there is no
redundancy so can I run another Engine that access the same Datacenter,
etc. as the first? Or does each Engine have to have it's own
Datacenter and the backup is achieved by migrating between the Engine's
Datacenters as needed.
* Given I have a hosted Engine setup how can I "undo" it and get to
running just the Engine on the host. Do I have to undo everything or
can I just install another instance of the Engine on the host but not
in a VM, move the VMs to it and then remove the Engine VM.
* System shutdown - If I shutdown the host what is the proper
procedure? Go to global maintenance mode and then shutdown the host or
do I have to do some other steps to make sure VMs don't get corrupted.
On ESXi we'd put a host into maintenance mode after shutting down or
moving the VMs so I assume it's the same here. Shutdown VMS since there
is nowhere to move the VMS, go into global maintenance mode. Shutdown.
On startup the Engine will come up, then I start my V
Ms.##SELECTION_END##
* Upgrading engine and host - Do I have to go to maintenance mode then
run yum to install the new versions on the host and engine and then run
engine-setup or do I need to go into maintenance mode? I assume the
4.0 production install will be much more involved but hopefully keeping
updated will make it a little less painful.
Thanks.

Re: [ovirt-users] Questions on oVirt
by Charles Tassell
Hi Brett,
I'm not an expert on oVirt, but from my experience I would say you
probably want to run the engine as a VM rather than on the bare metal.
It has a lot of moving parts (PostgresSQL, jBoss, etc...) and they all
fit well inside the VM. You can run it right on the bare-metal if you
want though, as that was the preferred means for versions prior to 3.6
Also, you don't need to allocate the recommended 16GB of RAM to it if
you are only running 5-10 VMs. You can probably get by with a 2-4GB VM
which makes it more palatable.
The thing to realize with oVirt is that the Engine is not the
Hypervisor. The engine is just a management tool. If it crashes, all
the VMs continue to run fine without it, so you can just start it back
up and it will just resume managing everything fine. If you only have
one physical host you don't need to really worry too much about
redundancy. I don't think you can assign a host to two engines at the
same time, but I might be wrong about that.
If you want to migrate between a hosted engine and bare metal (or
vice versa) you can use the engine-backup command to backup and then
restore (same command, different arguments) the configuration. I've
never done it, but it should work fine.
For a system shutdown, I would shutdown all of the VMs (do the hosted
engine last) and then just shutdown the box. I'm not sure if
maintenance mode is actually required or not, so I'd defer to someone
with more experience. I know I have done it this way and it doesn't
seem to have caused any problems.
For upgrades, I'd say shutdown all of the VMs (including the hosted
engine) then apply your updates, reboot as necessary, and then start the
VMs back up. Once everything is up ssh into the hosted engine, update
it (yum update), reboot as necessary, and you are good to go. If you
have a multi-host system that's a bit different. In that case put a
host into maintenance mode; migrate all the VMs to other hosts; update
it and reboot it; set it as active; migrate the VMs back and move on to
the next host doing the same thing. the reason you want to shutdown all
the VMs is that upgrades to the KVM/qemu packages may crash running VMs.
I've seen this happen on Ubuntu, so I assume it's the same on RedHat/CentOS.
As for the 4.0 branch, I'd give it a month or two of being out before
you use it for a production system. I started with oVirt just as 3.6
came out and ran into some bugs that made it quite complicated. On the
positive side, I learned a lot about how it works from getting advice on
how to deal with those issues. :)
