[Users] Templates and originating VM relationship
by Gianluca Cecchi 22 Apr '13

22 Apr '13

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 Gianluca

[Users] Power state of vm not in sync with real state
by Gianluca Cecchi 21 Apr '13

21 Apr '13

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..... https://docs.google.com/file/d/0BwoPbcrMv8mvUmdTM3lnZGVOYk0/edit?usp=sharing Thanks, Gianluca

Is the master release accessible via a repo.? 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. > I've been using Fedora 18.

[Users] snapshots, checkpoints etc...
by Jiri Belka 20 Apr '13

20 Apr '13

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. jbelka
