Hi Jaime,
The setup is quite simple, Tools needed are ucarp, rsync, Mysql
master-master replication.
We need to use a virtual IP which is configured using ucarp and that
virtual IP can be used to access Sunstone. I have setup this with 2 servers
but can configure ucarp with 3 or 4 servers. We nee

Sorry, my fault, attention is elsewhere ..
I actually use "writethrough" rather than "writeback" .. so with the exception
of the quote from the

Reading that piece of code it seems I was totally wrong with that:
--8<--
if (disk->cachemode) {
// bunch of code
} else if (disk->shared && !disk->readonly) {
virBufferAddLit(&opt, ",cache=off");
}

It should make some difference. We will take a look on
Mmm, I can't disagree if that's what the code says .. however turning
off the cache completely in the GUI does "seem" to make quite a *dramatic*
difference to the VM performance, whereas setting the sharable flag seems
to have no performance impact at all .. (when using writethrough ...) ???

I'll investigate a bit more on this issue but from the qemu driver
code it seems that cache is disabled with shareable flag.

Mmm, there has been some discussion around this ..
Technically using cache=writeback "should" be safe for migration.
(which is the method I use)
So .. I need "cache=writeback" and "sharable" for migration to happen.

Hi Bill,
That is an interesting feature, could you please open a ticket request
in dev.opennebula.org? This way we will be able to schedule it within
our roadmap.
Ideally, this would be configurable, there are scenarios where admins
would want users *not* to change the network of the VM template.
Hi,
OpenNebula does not manage kvm external snapshots. You could modify the
snapshot scripts [1] and then schedule onevm snapshot-create actions. But
this may have side effects, since OpenNebula won't be aware of any other
new VM files.
If you modify the drivers in the front-end's /var/lib/one/re
Hi Igor,
Just to let you know, this has been fixed in the main repo, and will
be available for upcoming releases (4.4.1 and 4.6).

Unfortunately the current version of cloud-init does not load new
network parameters after they are configured in some distributions.
There is a ticket to track that problem [1]

I agree - I'm actually writing this email from Arch Linux, actually :-).
I don't have much systemd expertise, but from looking at some examples it
looks something that we could easily do. Let's see how systemd's
