No - you can change the cluster settings (virt service/gluster service) only if the application mode is both. In virt only mode, the cluster is virt only, and same with gluster-only. So if you want user to be able to change the mode *after* installation, this config (ApplicationMode) must be exposed in the engine-config tool.

Re: [Users] Starting VM gets paused
I got hit up with the same issue - I think it had something to do with latency or timeout to my NAS/SAN, despite an isolated prioritised storage network. I'm guessing the VDSM puts VM's in a paused state whenever it hits a slight panic or speed-wobble.

Re: [Users] Fast way to see all snapshots on my infra?
Hi Gianluca,
You can try something like this (dirty) command:

cp /dev/null /tmp/ovirt-snapshots; echo -e list vms\nexit
/tmp/ovirt-vms; for VM in `ovirt-shell -l ${URL} -u ${USER} -c -I
-f /tmp/ovirt-vms | grep name | tr -s ' ' ' ' | cut -d' ' -f3`; do echo
list snapshots --vm-identifier ${VM} --show-all
/tmp/ovirt-snapshots; done; echo exit /tmp/ovirt-snapshots;
ovirt-shell -l ${URL} -u ${USER} -c -I -f /tmp/ovirt-snapshots

[Users] Feature request: allow usbtablet and vram config via UI
Allow for a usbtablet input device to be enabled and used. Perhaps via the console configuration UI for a VM in the admin and user portals. -Highly useful in the event that a guest OS does not have the spice agent loaded nor is it available for said guest OS. -Also in the case of guest OS that simply does not want to work and play well with input type='mouse' bus='ps2' - All Operating systems since ~1998 understand input type='tablet' bus='usb'/ and will deal with mouse events in absolute mode. Allow for vram and vram_ size to be configurable for CIrrus(VNC) and QXL(Spice) console types. Again probably best suited to have this on console configuration UI for a VM in the admin and user portals. - Default VRAM sizes are not enough to allow for larger resolutions and pixel depths at times. - Especially the case in multiple monitor SPICE, fullscreen, or VNC consoles - More VRAM is useful in the case of attempting to run accelerated applications within a QXL configured guest. The above can be altered via VDSM hooks however this is rather painful. Additionally these options or similar are configurable in other competing solutions. - DHC ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] User Portal
Hi, If you login with PowerUser permission you have 2 tabs (Basic and Extended) where Basic is the UserPortal and Extended the PowerUserPortal. So you can switch between these 2 views. Btw, in RHEV (3.0 and 3.1) I see a (for me) strange behaviour and haven't tested if this is the same in oVirt. When installing RHEV a Default datacenter is created and everyone has permission on template blank. As long as I don't remove permissions on blank template user with role UserRole start in PowerUserPortal (Extended view) instead of UserPortal (Basic view) - without permission on template blank they can't switch between these 2 views/portals (which is the expected situation - users with UserPortal permission shouldn't be aware of the PowerUserPortal). Is this bug or intended?

First thing that is strange is that your engine is taking 7.7 GiB of RAM, which it should never take, as it is by default limited to 1 GiB. Did you assign more memory to the engine on purpose? How much? If you assign a lot of memory it can start to consume a lot of CPU just for garbage collection. You may want to enable verbose garbage collection adding this to /etc/sysconfig/ovirt-engine (or /etc/ovirt-engine/engine.conf if you are using the latest source code): ENGINE_VERBOSE_GC=true Then restart the engine and it will start to dump garbage collection statistics to /var/log/ovirt-engine/console.log. The garbage collection should be quite silent in an low activity system. We used to have a bug that caused the max amount of memory not be correctly limited, but it was fixed long ago: http://gerrit.ovirt.org/7952 The other thing that seems strange is the amount of CPU that it is consuming. Do you have many hosts managed by that engine? In an otherwise idle environment the CPU consumption is caused by the periodic polls of the hosts, one each two seconds by default. If you see continually the engine using a significant amount of CPU (you the output of top above it is 9%) it could be useful to get a snapshot of the stacks of threads, to see which threads in particular are consuming the CPU. Send the QUIT signal to the engine process and it will dump the stacks of the threads to /var/log/ovirt-engine/console.log: # kill -3 $(cat /var/run/ovirt-engine.pid) Once you have that dump you can check which thread is consuming the CPU as follows: 1. Get the PIDs of the threads of the engine together with their use of CPU: # ps -L -u ovirt -o tid,pcpu 2. If you see one of them consuming a high amount of CPU time then try to find it in the stack dump generated in /var/log/ovirt-engine/console.log. Lets assume that the PID is 13397, for example, translate it to hex: # printf %04x\n 13397 3455 3. Then look in /var/log/ovirt-engine/console.log for a line containing nid=0x3455. There you will find the stack trace of that thread, something like this: ajp-/127.0.0.1:8702-Acceptor-0 daemon prio=10 tid=0x7f41e0220800 nid=0x3493 runnable [0x7f41dbdf2000] java.lang.Thread.State: RUNNABLE ... Most threads will be waiting, but if you find one thread that is consistently RUNNABLE then there is probably an issue. The dump of the stack of that thread can help to find out what it is doing and why it is consuming the CPU. I don't have a lot of experience with jboss, so im not sure it thats good or bad. I did the jboss restart, and that helped a little, but its still a little sluggish again, now a few days later.

Currently the question asked at setup is this : The engine can be configured to present the UI in three different application modes. virt [Manage virtualization only], gluster [Manage gluster storage only], and both [Manage virtualization as well as gluster storage] where both is the default. If this is confusing to the user, we can change this message. Suggestions? I would either: (a) put Virt as the default, or I would go for this one, this keeps backwards compatibility. Is there an easy method to change this configuration later? Yes, changing the cluster settings. No - you can change the cluster settings (virt service/gluster service) only if the application mode is both. In virt only mode, the cluster is virt only, and same with gluster-only. So if you want user to be able to change the mode *after* installation, this config (ApplicationMode) must be exposed in the engine-config tool. So if I'll try to sum up (with reference to other emails on this thread). 1. Default should be virt only 2. Keep the question and better explain what is the Gluster option (preferable a link to the relevant page) 3. Add a config option to easily change the selection later Need to think about the implication of the third option in case the change conflicts with hosts/clusters that are already configured other wise. Example: Initial selection was Virt and now adding dual mode - always OK Example: Initial selection was Virt, no host in the setup, and now changing to Gluster mode - OK Example: Initial selection was Virt, Hosts already in the setup installed in virt mode, and now changing to Gluster mode - What will we do? My take, Config option can only set to dual mode, never the other way around. This will save the need to add sophisticated logic Sounds right? (b) remove this question entirely - if someone is installing oVirt, assume they want to manage virt. If someone is installing Gluster, have an option during the Gluster install to have the oVirt management console. We do want people to get exposed to the Gluster option. If someone wants to manage both their Gluster bricks and their virt with oVirt, I would make that a post-install option to oVirt - perhaps with an extra package to install (which would depend on the later version of Gluster).

(b) remove this question entirely - if someone is installing oVirt, assume they want to manage virt. If someone is installing Gluster, have an option during the Gluster install to have the oVirt management console. We do want people to get exposed to the Gluster option. If someone wants to manage both their Gluster bricks and their virt with oVirt, I would make that a post-install option to oVirt - perhaps with an extra package to install (which would depend on the later version of Gluster).

There have been several messages from users since the oVirt 3.2 release asking why they need Gluster 3.4 pre-releases to run oVirt. My understanding is that you don't need Gluster 3.4 unless you want to manage a Gluster cluster with oVirt.

And... if this option is in UI, then... why do we need anything at setup...? user can log into the system and configure the cluster in any way he likes. Well that was the initial idea behind the dual mode, everything exposed and the user selects in the GUI on the cluster level what to use. This confuses users as this thread apparently exposes. Users that do not care about Glusters would like not to bother to set this up on each cluster, and vice verse. I am thinking into the future that when first login into the admin console there should be some wizard, instead of performing this at setup time. If configuration options are allowed to be dynamically modified (and we are working to have it so) this does not contradict, the wizard is just a first login graphical setup.

First thing that is strange is that your engine is taking 7.7 GiB of RAM, which it should never take, as it is by default limited to 1 GiB. Did you assign more memory to the engine on purpose? How much? If you assign a lot of memory it can start to consume a lot of CPU just for garbage collection. You may want to enable verbose garbage collection adding this to /etc/sysconfig/ovirt-engine (or /etc/ovirt-engine/engine.conf if you are using the latest source code): ENGINE_VERBOSE_GC=true Then restart the engine and it will start to dump garbage collection statistics to /var/log/ovirt-engine/console.log. The garbage collection should be quite silent in an low activity system. We used to have a bug that caused the max amount of memory not be correctly limited, but it was fixed long ago: http://gerrit.ovirt.org/7952 The other thing that seems strange is the amount of CPU that it is consuming. Do you have many hosts managed by that engine? In an otherwise idle environment the CPU consumption is caused by the periodic polls of the hosts, one each two seconds by default. If you see continually the engine using a significant amount of CPU (you the output of top above it is 9%) it could be useful to get a snapshot of the stacks of threads, to see which threads in particular are consuming the CPU. Send the QUIT signal to the engine process and it will dump the stacks of the threads to /var/log/ovirt-engine/console.log: # kill -3 $(cat /var/run/ovirt-engine.pid) Once you have that dump you can check which thread is consuming the CPU as follows: 1. Get the PIDs of the threads of the engine together with their use of CPU: # ps -L -u ovirt -o tid,pcpu 2. If you see one of them consuming a high amount of CPU time then try to find it in the stack dump generated in /var/log/ovirt-engine/console.log. Lets assume that the PID is 13397, for example, translate it to hex: # printf %04x\n 13397 3455 3. Then look in /var/log/ovirt-engine/console.log for a line containing nid=0x3455. There you will find the stack trace of that thread, something like this: ajp-/127.0.0.1:8702-Acceptor-0 daemon prio=10 tid=0x7f41e0220800 nid=0x3493 runnable [0x7f41dbdf2000] java.lang.Thread.State: RUNNABLE ... Most threads will be waiting, but if you find one thread that is consistently RUNNABLE then there is probably an issue. The dump of the stack of that thread can help to find out what it is doing and why it is consuming the CPU. I don't have a lot of experience with jboss, so im not sure it thats good or bad. I did the jboss restart, and that helped a little, but its still a little sluggish again, now a few days later.
