Migration from Xenserver 6.2 to KVM.
by Kalil de A. Carvalho
Hello all.
I work in a company that want test KVM/oVirt.
The problem is the current environment running Xenserver 6.2 and is
mandatory that we can migrate from the Xenserver to KVM.
Research about it I saw that is not supported.
I this true?
Best regards.

ovirt 3.5 and power outages
by Kostyrev Aleksandr
good day, everybody!
I've got three node cluster with power management enabled.
As far as I understood to restart vms on the other host in the cluster
in case when host suffered from power outage
the engine has to be able to connect to host (specifically to vdsm) to
be sure that host has been rebooted and it's not running any vms.
But what if I'm running a lot of vms on the host and it's 3 o'clock in
the morning and
1) engine has rebooted the host but the host cannot boot because of some
hardware problem or new kernel gives a kernel panic?
2) the host's motherboard burned out and it cannot get booted
so the engine will never connect to host and therefore all the vms that
were running on that host won't migrate to other node in the cluster.
So my cluster in that case is useless 'cause I'm not there to press
"confirm host has been rebooted'.

you don't need to know python.
did you run the engine side commands (engine-config -s
UserDefinedVMProperties... and restarted the engine)?

Ovirt and power saving
by Mario Giammarco
Hello,
I would like to ask if it is possible to do this use case with ovirt:
1) two servers powered on
2) operator suspend some virtual machines
3) load falls down
4) ovirt shutdown one server
Then operator unpauses virtual machines and ovirt starts again the 2nd
server.
Thanks,
Mario

Put the engine inside hosts after installation
by Mario Giammarco
Hello,
I would like to try ovirt with hosted engine installation.
I had so many problems (I have written them in another thread) so I will
not try anymore hosted installation (up and running with ovirt 3.5 tutorial)
But now I would try this approach: I install the engine on a dedicated
server or as a virtual machine in another kvm based virtualizator.
Now I create an ovirt cluster and use it.
Can I after that install change my mind and so move the engine as a vm in
the cluster?
Or can I install a new engine in the cluster and powerdown the first engine?
Thanks in advance for help,
Mario

Low cost fencing/stonith devices
by Mario Giammarco
Hello,
I ask this question again to see if there are some improvements.
I am searching for a low cost stonith/fencing device for servers or
hardware that has no ipmi/ilo on board.
I see that there are some interesting products on the market like ubnt/mfi
mpower that are controllable power outlets but there is no driver for them.
In my use case WOL support will be enough (using it with ssh or shared
storage fencing) but as far as I know WOL is not yet supported in ovirt.
So is there some fencing device supported in 100/200$ price range?
Thanks,
Mario
