[Users] Templates and originating VM relationship
by Gianluca Cecchi
Hello,
oVirt 3.2.1 on Fedora 18.
I customize a CentOS 6.4 VM and when I comfortable I select "make template".
I don't take any snapshot for the VM before this.
I thought that VM would have been disappeared, transforming itself
into a template, instead at the end I have both the template and the
originating VM.
Apparently with the same name for the disk and the same storage domain....
What is exactly the relationship between them?
Can I safely remove the originating VM?
I already tested making template and then deleting it and then being
able to power on again VM and make a new template from the originating
VM.
The rhevm 3.1 admin manual is not so clear about this: it contains a
note regarding
"
Take a snapshot of the virtual machine at this stage if you wish to
use the virtual machine
(as a virtual machine) after using it to create a template.
"
But if behavior of oVirt 3.2.1 has to be the same with it, this
doesn't explain itself based on my experience....
Thanks in advance for any information

[Users] Power state of vm not in sync with real state
by Gianluca Cecchi
Hello,
oVirt 3.2.1
Installed rhev-agent-2.3.16-6.el6.x86_64 on CentOS 6.4 VM.
I click shutdown button (red square icon that implies 1 minutes
timeout before actual shutdown).
After a few seconds the icon at left of the VM becomes "stopped" (red
square), but actually shutdown has not benn taking palce yet at
all.....
Could it be possible to have the icon in sync with real stae?
See this image where I have a spice console opened at VM. shutdown not
yet beagun and icon in web admin gui that shows the VM as powered
off.....

from your question I understand that you are currently using ovirt 3.2.1 rather
than master [to answer Itamar's question from the previous e-mail], and that explains
the slowness of the portals on IE8 that you are experiencing.
Please note that on oVirt master, the performance improvement patches for IE8 affect
only the user portal; unfortunately, the admin portal still suffers from performance
problems on IE8.
with regards to the master release accessibility: I am not sure if we have a master
release; you can build oVirt-engine directly from the code-repo by following the
instructions in the following wiki-page: http://www.ovirt.org/Build_and_Install_Engine_RPM
@Itamar/others: do we have some kind of a nightly/weekly/occasionally repository of
ovirt builds/rpms? the IE8 performance patches were introduced to oVirt master on March 1
(almost 2 months ago), so anything rebased from ovirt master at that point in time or
afterwards would be helpful.

as Itamar mentioned below, spice-devel mailing-list members (CC'd) should be able to answer
this question.

[Users] AllInOne installation issue

When running the AllInOne installation =A8engine-setup --config-allinone=3Dyes=A8
the last step of my installation always fails. I freshly setup a fedora 18
box (minimal) and directly installed ovirt:
sudo yum localinstall
http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm
sudo yum install ovirt-engine-setup-plugin-allinone
engine-setup --config-allinone=3Dyes
I also tried with the nightly build which did not solve the issue for me.
Any idea how to fix this?
This is the end of my install log:

[Users] snapshots, checkpoints etc...
by Jiri Belka
Probably not the best list for this question but anyway...
* "snapshot" as it is done with 'savevm' from qemu monitor saves disk,
cpu, memory state of running VM... but
1. it must be qcow2 image
2. it pauses the VM for couple of seconds
is this right?
* snapshots is only for block devices, are done offline
* live snapshot is only for block devices, can be done online
* snapshot tree with branches is not supported now
am I right?
So my understanding there is no way to have a "photo", in qemu language
_checkpoint_, in VMWare language _snapshot_ without interupting the VM.
Am I right? Any comments?
This topic is quite confusing while searching Internet.
