Re: [ovirt-users] Hosted Engine on oVirt Node Hypervisor
Hey Jason, - Original Message - I'm setting up some new oVirt infrastructure, and wanted to give hosted engine a try. I downloaded and installed the oVirt Node Hypervisor ISO (3.5-0.999.201502231653.el7.centos) on one of 3 nodes. One of the options in the hypervisor menu is Hosted Engine. This requires an Engine ISO/OVA URL for download. The thing is - as far as I can tell, there is no download link for this ISO/OVA on the ovirt release web site. I also can't find anything in the documentation that refers to it (or even this menu in the hypervisor). I did find this after some searching: Yes, you are right, the documentation of Hosted Engine is currently ... sparse. http://jenkins.ovirt.org/user/fabiand/my-views/view/Node/job/ovirt-appliance_engine-3.5_master_merged/oVirt-Engine-Appliance-CentOS-x86_64-7-20150319.424.ova (Now replaced with a build from 0322). I asked on the ovirt IRC channel and was told that this might work, but because of new functionality introduced recently that it also might not. If the feature is available in the node ISO, shouldn't there be an appropriate release of the hosted engine ISO/OVA that works hand in hand with the node that I've downloaded? If it's not there because it isn't ready, isn't this functionality something that should be added to maybe a beta node release and tested before being released into the stable node hypervisor release? Yes, the problem here is with the ovirt-appliance. We did not start building images based on the 3.5 status of the appliance. I'll see if we can get up a builder for the ovirt-3.5 branch up quickly. I asked on the IRC channel whether it might be possible for me to kickstart my own engine from the node. I ran into trouble with that as well. On the installed node, I can only configure one network interface. This is, of course, intended to enable ovirtmgmt for communication with engine which would take over and configure everything else for you. Of course, when you don't yet have engine installed and need to get it, this leads to a chicken and egg problem. To kickstart engine on node, I need an IP (from mgmt), an image (I guess it could come from the mgmt network), but then I also need access to the external network (on another NIC) to be able to install the appropriate ovirt yum repository, and download the engine! If I installed my own node manually instead if using ISO, I guess I could configure the network, and make it work, but I'm trying to take advantage of the work that has already been put into node to make this all possible. I believe I saw a corresponding bug for what you described above. Does it help if you temporarily add a route to your management network's router, which enables the hosted-engine host to access the relevant networks (external, storage, …)? Greetings fabian Anyway, I'm certainly interested in any feedback from users who have been able to make this work. I guess I could kickstart one node as an engine, create the virtual image there, suck the ova down to the mgmt server, install node, then use node to re-suck down the hosted engine image, but it just seems like a lot of extra work. Somehow I think it's intended to be a little more straightforward than that.

I receive an error stating that we cannot connect to the host (I assume that is the bare metal system hosting the engine guest in this context, would be nice if it could echo the command it's issuing but cannot see it in the logs). DNS and ssh are working fine, I can ssh between the host and guest without issue. SElinux is disabled, as is iptables. I can't figure out how to move forward. I'm running CentOS 7 and ovirt 3.5. Here is the last of the log file before I get booted out of the installer: http://pastebin.com/LDqFHSZw So my questions are: 1) What am I missing here? The engine VM will contact your host via SSH in order to deploy it within oVirt; it seams that is failing there. Cold you please try to connect from the engine VM to the host via SSH? Could you please attach your host-deploy logs from the engine VM (the should be under /var/log/ovirt-engine/host-deploy/) ? 2) how do I pick up from where I left off and use the engine I've successfully created? You can try to run hosted-engine --deploy --config-append=/etc/ovirt-hosted-engine/answer.conf but it success really depends from how and where it stopped on first attempt (a partial failed setup it's by definition a dirty environment) If you get any warning or errors it would be better to redeploy the engine VM cleaning the shared storage.

Re: [ovirt-users] [Gluster-users] VM failed to start | Bad volume specification
Hi All, With the help of gluster community and ovirt-china community...my issue got resolved... The main root cause was the following :- 1. the glob operation takes quite a long time, longer than the ioprocess default 60s.. 2. python-ioprocess updated which makes a single change of configuration file doesn't work properly, only because this we should hack the code manually... Solution (Need to do on all the hosts) :- 1. Add the the ioprocess timeout value in the /etc/vdsm/vdsm.conf file as :- [irs] process_pool_timeout = 180 - 2. Check /usr/share/vdsm/storage/outOfProcess.py, line 71 and see whether there is still IOProcess(DEFAULT_TIMEOUT) in it,if yes...then changing the configuration file takes no effect because now timeout is the third parameter not the second of IOProcess.__init__(). 3. Change IOProcess(DEFAULT_TIMEOUT) to IOProcess(timeout=DEFAULT_TIMEOUT) and remove the /usr/share/vdsm/storage/outOfProcess.pyc file and restart vdsm and supervdsm service on all hosts Thanks, Punit Dambiwal On Mon, Mar 23, 2015 at 9:18 AM, Punit Dambiwal hypu...@gmail.com wrote: Hi All, Still i am facing the same issue...please help me to overcome this issue...

Re: [ovirt-users] Hosted engine multipath iscsi
Hi, I am planning an ovirt hosted-engine installation with two nodes and an iSCSI SAN for the engine and VMs and NFS for ISO and Export domains, on another NAS. The iSCSI SAN have two controllers, each one have two NICs at 1Gb/s, and I was planning to use a bond manually configured (two NICs) on hypervisors/nodes, so I'll end up with 4 paths. - Creating a bond is it a good idea? or do I have to use the node NICs separately as in the link mentioned earlier? - If I'll use a bond, will it survive the engine's installation? - After the engine's installation, the link(s)/path(s) used to connect to the SAN storage will also be used to connect to the NAS, this will constitute a storage network, this network will be mandatory so I can't create an iSCSI bond on top of it. Will the multipath be configured automatically by the engine's installation on all hypervisors/nodes? thanks in advance. 2015-03-24 10:30 GMT+01:00 Simone Tiraboschi stira...@redhat.com: - Original Message - From: Baptiste Agasse baptiste.aga...@lyra-network.com To: users users@ovirt.org Sent: Tuesday, March 24, 2015 10:12:36 AM Subject: [ovirt-users] Hosted engine multipath iscsi Hi all, I'm currently testing ovirt 3.5 on centos 7, with hosted engine on iscsi equallogic SAN..

The iSCSI SAN have two controllers, each one have two NICs at 1Gb/s, and I was planning to use a bond manually configured (two NICs) on hypervisors/nodes, so I'll end up with 4 paths. - Creating a bond is it a good idea? or do I have to use the node NICs separately as in the link mentioned earlier? Creating a iSCSI bond is indeed the recommended way to use iSCSI multipathing with oVirt http://www.ovirt.org/Feature/iSCSI-Multipath#iSCSI_Bond_behaviour But it relies on oVirt logical network that are still not available when you are deploying hosted-engine and with oVirt 3.5 you cannot than edit the hosted-engine storage domain. A manually configured bond should work but than is not directly managed by the engine for additional hosts. - If I'll use a bond, will it survive the engine's installation? hosted-engine is generally working with bonded interface and they generally survive but honestly I never directly tried deploying hosted-engine on iSCSI over bonded interface. Please report us if you find any issue with that. - After the engine's installation, the link(s)/path(s) used to connect to the SAN storage will also be used to connect to the NAS, this will constitute a storage network, this network will be mandatory so I can't create an iSCSI bond on top of it. Will the multipath be configured automatically by the engine's installation on all hypervisors/nodes? I think no, currently you cannot edit the hosted engine storage domain from the engine to configure the iSCSI bond involving another logical network. We are working on that for 3.6 thanks in advance. 2015-03-24 10:30 GMT+01:00 Simone Tiraboschi stira...@redhat.com: - Original Message - From: Baptiste Agasse baptiste.aga...@lyra-network.com To: users users@ovirt.org Sent: Tuesday, March 24, 2015 10:12:36 AM Subject: [ovirt-users] Hosted engine multipath iscsi Hi all, I'm currently testing ovirt 3.5 on centos 7, with hosted engine on iscsi equallogic SAN..

Nothing will get fixed if no one bothers to

There's already an open BZ:
https://bugzilla.redhat.com/show_bug.cgi?id=1158108
I'm not sure if that is exactly the same problem I'm seeing or not; my
vdsm process seems to be growing faster (RSS grew 952K in a 5 minute
period just now; VSZ didn't change).
For those following this I've added a comment on the bz [1], although in
my case the memory leak is, like Chris Adams, a lot more than the 300KiB/h
in the original bug report by Daniel Helgenberger .
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1158108
That's interesting (and worrying).
Could you check your suggestion by editing sampling.py so that
_get_interfaces_and_samples() returns the empty dict immediately?
Would this make the leak disappear?
Looks like you’ve got something there. Just a quick test for now, watching
RSS in top. I’ll let it go this way for a while and see what it looks in a
few hours.
System 1: 13 VMs w/ 24 interfaces between them

12:00 136400
restarted with sampling.py modified to just return empty set:
def _get_interfaces_and_samples():
links_and_samples = {}
return links_and_samples
Thanks for the input. Just to be a little more certain that the culprit
is _get_interfaces_and_samples() per se, would you please decorate it
with memoized, and add a log line in the end
@utils.memoized # add this line
def _get_interfaces_and_samples():

logging.debug('LINKS %s', links_and_samples) ## and this line
return links_and_samples
I'd like to see what happens when the function is run only once, and
returns a non-empty reasonable dictionary of links and samples.
Looks similar, I modified my second server for this test:

We currently is not able to configure the SAN in D1 X1 to be seen by blades in both sides. So we are pretty much stuck with our current ovirt mgmt. vms configuration. That is not an hosted engine issue, it's a design issue. If you want to provide HA or disaster recovery capabilities between your two racks both of them should be able to access your shared storage otherwise you simply cannot directly migrate a VM from D1 to X1 or viceversa. If you have two racks with two different and insulated SAN and they cannot access each other you have two distinct insulated systems and you could only manage them as that; you could use a single oVirt engine for that but the engine VM itself could not migrate to the other system by design. I guess the main concern is how to control all the virtual machines with oVirt infrastructure if both our ovirt-mgmt vms went down, how can we start them up again. That also applies to any virtual machines. If the oVirt mgmt infrastructure is not able, I think there is no way to start a VM, correct? At low level you could directly use virsh directly on the host to start a VM directly over libvirtd but it's really a extreme solution.

It clarified some of the confusion I have with the hosted-engine. However, I still have one question. Sorry. It is my bad that I did not explain clearer on our hardware configuration, mainly on the SAN. We also have 2 SAN, one on D1 another one on X1. The blades on D1 can only see the storage in SAN D1. X1 blades can only see SAN X1. Does it mean that we will need to manage our oVirt environment separately when we switch to use hosted-engine? Because from your explanation, the hosted-engine in selected nodes will use separate iSCSI hosted-engine storage to store the DB. With hosted engine not only the DB but all the engine VM is going to be stored on a dedicated iSCSI LUN so each host involved (not managed by) in hosted-engine should be able to access that device in order to be able to start the engine VM after other host failures. So, if you want to have it restarting the engine VM on a X1 host after a complete failure of D1 rack, you need to store the engine VM on a location that is accessible both by D1 and X1. NFS could be an option too. Otherwise you should check your storage path design in order to have a cross rack path; you could also evaluate iSCSI multipathing. Since there is no cross D1 X1 storage in our current config, that means we need separate hosted-engine setup on each side.

As I know he needs to run virtual machine with huge amount of over allocated memory (more than one host has) and when it is really needed then migrate it to host where is much more memory. It looks to me like nice use case for oVirt. But here is his own question. Currently, the virtual machine of given memory size S cannot be run on the host with less than S physical memory. We need to run several virtual machines (with unpredictable memory requirements) on the cluster consisting of several different hosts (with different amount of physical memory) in such the way that any virtual machine can be run on any host. Due to Ovirt limitation, virtual machines memory sizes has to be set to the MINIMUM of host physical memory sizes (in order to be able to run any virtual machine on any host). As far as I know, this rule has no connection to cluster's Memory optimization 'Max Memory Over Commitment' parameter. But we cannot predict memory needs of our virtual machines so we need to set the memory size of all of them to the MAXIMUM of host's physical memory sizes. Explanation: We are running several computational tasks (every one on single independent virtual machine). We have several (and different) host machines (see Figure 1). 1. At the beginning, every task consumes a decent amount of memory. 2. After a while, some task(s) allocate a huge amount of memory (Figure 2). At this moment, some of them cannot continue (due to unavailable memory on its current host) without migration to the host with higher memory available. 3. After migration (Figure 3), all tasks may continue. 4. Some tasks finally consumes a LOT of memory (Figure 4). The algorithm above cannot be realized, since every virtual machine (i.e. task) has predefined (and fixed when running) its memory size set to the MINIMUM of hosts physical memory sizes.

Re: [ovirt-users] Hosted Engine config in our hardware environment
Simone: I discussed with our SAN guy. We currently is not able to configure the SAN in D1 X1 to be seen by blades in both sides. So we are pretty much stuck with our current ovirt mgmt. vms configuration. I guess the main concern is how to control all the virtual machines with oVirt infrastructure if both our ovirt-mgmt vms went down, how can we start them up again. That also applies to any virtual machines. If the oVirt mgmt infrastructure is not able, I think there is no way to start a VM, correct?

It clarified some of the confusion I have with the hosted-engine. However, I still have one question. Sorry. It is my bad that I did not explain clearer on our hardware configuration, mainly on the SAN. We also have 2 SAN, one on D1 another one on X1. The blades on D1 can only see the storage in SAN D1. X1 blades can only see SAN X1. Does it mean that we will need to manage our oVirt environment separately when we switch to use hosted-engine? Because from your explanation, the hosted-engine in selected nodes will use separate iSCSI hosted-engine storage to store the DB. With hosted engine not only the DB but all the engine VM is going to be stored on a dedicated iSCSI LUN so each host involved (not managed by) in hosted-engine should be able to access that device in order to be able to start the engine VM after other host failures. So, if you want to have it restarting the engine VM on a X1 host after a complete failure of D1 rack, you need to store the engine VM on a location that is accessible both by D1 and X1. NFS could be an option too. Otherwise you should check your storage path design in order to have a cross rack path; you could also evaluate iSCSI multipathing. Since there is no cross D1 X1 storage in our current config, that means we need separate hosted-engine setup on each side.

We have been using oVirt for over 3 years. When we first setup oVirt environment, Hosted Engine componment did not exist. Our question is should we migrate our current configuration to use Hosted Engine? First let me give an overview of our configuration. We have blade servers in 2 separate racks. D1 X1. Each side has 10 blades. Storage is iSCSI SAN. Inside our oVirt 3.5.0.1-1.el6 installation, it is configured with 2 data centers. D1 X1. Each datacenter has the 10 blades for that side. The management function of oVirt (oVirt web console) is running off 2 VMs, ovirt-mgmt-1 on D1, and ovirt-mgmt-2 on X1. We have keepalived to maintain a flowing IP for the oVirt management console. The keepalived script makes sure only one copy of ovirt-engine is running at any time. It can be on D1 or X1. The mgmt VMs have Postgresql setup in replication mode. In case one of the mgmt vm failed, the other mgmt vm on the other rack can pick up the mgmt role. Both mgmt VMs can see all blades and SAN resources on D1 X1. This configuration has been working well for us. The drawback is if both ovirt mgmt vm crashed, we will not be able to start them or make any change to the ovirt environment. It is because the mgmt VMs are running within the oVirt domain. We tried to upgrade our configuration to Hosted Engine configuration. From what I understand, the Hosted Engine will run in a separate storage domain. In both times we tried to upgrade to Hosted Engine, they both failed during export and import of current configuration. Here you can find some hint about how to migrate to hosted-engine: http://www.ovirt.org/Migrate_to_Hosted_Engine I think my questions are: - will the Hosted Engine model works in our hardware configuration. With hardware in 2 racks, D1 X1. Can a single Hosted Engine manage hardware on both sides? - How can we achieve redundancy when running Hosted Engine? We need to have

Not really - ovirt-hosted-engine-ha does that :-) In principle you can check how it does that and do so too. IIRC we have an RFE to make it support more VMs (in addition to the engine's one). IIUC this will not help you directly, because HA still relies on shared storage. Best, -- Didi ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
