rmk | There really isn't much information about running xenserver with openstack | 04:58 |
rmk | I've only found one document | 04:58 |
rmk | Is anyone using openstack with xenserver in a production environment? | 05:04 |
*** rms-ict has quit IRC | 05:07 | |
Alowishus | well aren't XCP and XenServer roughly interchangeable? most any doc which would refer to XCP and XAPI would apply identically to XenServer | 05:13 |
rmk | Yes they're effectively the same | 05:18 |
rmk | I'd gladly run XCP if it's more supported | 05:18 |
rmk | Are there more docs around XCP? | 05:18 |
rmk | http://wiki.openstack.org/XenServerDevelopment -- is the only one I see referencing Xenserver/XCP/XAPI at all | 05:19 |

rmk | Is there supposed to be one nova compute instance for each hypervisor? | 06:49 |
bnight | rmk: good morning I read the docs and somewere it was writen that you need to have one nova compute instance for each hypervisor | 06:52 |
rmk | So there's really no advantage to using xenserver in this case, since pooling really has no benefit | 06:53 |
bnight | so if you want to use for example xenserver and vmware esxi you need to nova compute instances one to manage xen server and one to manage vmware esxi | 06:53 |
rmk | bnight: Sure -- but if there are 10 servers in the xen pool, do you need a compute instance for each one? | 06:54 |
bnight | however because different hypervisors needs different image types my advice is to use only one hypervisor in your cloud infrastructure | 06:54 |
bnight | rmk: yes you need compute instance for each one | 06:55 |
rmk | hmm and with xenserver each of those needs to be a domu, so one vm per physical server .. am I understanding correctly? | 06:55 |
bnight | why only one vm per physical server ? | 06:56 |
rmk | no I mean one nova compute vm needs to exist on each xenserver instance | 06:57 |
bnight | yes | 06:58 |
rmk | Seems like kvm would be a better direction then | 06:58 |
bnight | why ? | 06:58 |
bnight | it depends on what you want to do with your infrastructure | 06:59 |
rmk | nova compute would just run on the kvm hypervisor itself, rather than a vm | 06:59 |
bnight | for example i want to be able to use vmware esxi for hypervisor | 06:59 |
rmk | have you managed to get that working with openstack? | 06:59 |
bnight | yes you are corect but if you have 10 servers you still need to install 10 nova computes | 07:00 |
bnight | no I am just in playing state right now so I have only a basic setup with qemu on a vmware player vm it`s great anyway | 07:01 |
rmk | nice | 07:01 |
rmk | thanks for clearing this up for me | 07:01 |
bnight | today my plan is to create some use cases I run a small hosting company and will be great to see how my customers will benefit if I deliver to them cloud infrastructure | 07:01 |
bnight | so if you have any ideas for what I can use the cloud please advice I am still new in this using I can configure and install everything but can`t find a use cases examples will be great | 07:05 |

deshantm | rmk: did you do a pip install off xenapi recently? | 18:06 |
deshantm | rmk: also, by the way we are also porting the XCP toolstack (xapi) to Debian/Ubuntu, so that might be a use case that you are looking for | 18:07 |
deshantm | rmk: it's called Project Kronos (http://blog.xen.org/index.php/2011/07/22/project-kronos/) | 18:08 |
rmk | deshantm: I did | 18:10 |
*** ldlework has quit IRC | 18:10 | |
rmk | deshantm: My concern is that I'll need to run a nova-compute instance on each hypervisor as a domu | 18:10 |
rmk | Sorry I just thought about it and yes you're right that would solve the problem as well | 18:12 |
*** stewart has joined #openstack | 18:12 | |
rmk | deshantm: What's the possibility of running nova-compute on dom0 of xcp? | 18:17 |
*** stewart has quit IRC | 18:17 | |
deshantm | rmk: that is the point of Project Kronos | 18:18 |
deshantm | rmk: as for documentation we are working as quick as we can to get more out there. Until then ask me anything. (todd.deshane@xen.org) | 18:21 |
rmk | Just want to clarify something | 18:22 |
rmk | If I have a pool of 10 xenservers, do I need a nova-compute domu on each one of the hypervisors, or is one enough for the entire pool? | 18:22 |
OutBackDingo | deshantm: and it actually works on debian :) | 18:25 |
comstud | rmk: need one compute node per xenserver node | 18:28 |
*** nerens has quit IRC | 18:28 | |
*** bengrue has joined #openstack | 18:28 | |
OutBackDingo | comstud: even if their all pooled? why ? | 18:28 |
comstud | OutBackDingo: Ah, pooled. Hm. | 18:30 |
OutBackDingo | i dont see any reason is all hosts re pooled and using shared storage why you would need more then 1 nova compute vm | 18:31 |
OutBackDingo | since it has access to the whole pool | 18:31 |
comstud | OutBackDingo: I don't think there's any explicit support for pools right now... so I'm not sure how things might work with it | 18:31 |
OutBackDingo | im failrly coviced nova compute is oblivious to pools and only cares about resources, which are provided by a pool | 18:32 |
OutBackDingo | to compute it looks like 1 big machine | 18:32 |
comstud | I'm not sure if there needs to be expicit support.. it's possible it may work with 1 compute node, then, pointing the compute node to a master. | 18:33 |
rmk | just not sure how that interaction works across the entire pool when /boot/guest comes into play | 18:33 |
comstud | right | 18:33 |
*** Capashen has joined #openstack | 18:33 | |
deshantm | for xenserver it is one compute node per hypervisor... I checked on this... I'll get the explanation | 18:33 |
comstud | yeah, though with pools, it's possible a pool looks like 1 big hypervisor | 18:34 |
comstud | to a compute node | 18:34 |
comstud | if you point the compute node to a pool master | 18:34 |
comstud | i haven't used nova with pools, so I dunno. | 18:34 |
rmk | deshantm: I'm definitely curious as to why as well | 18:35 |
OutBackDingo | i always just pointed nova at the pool master | 18:35 |
comstud | OutBackDingo: and it's worked? if so, cool. | 18:35 |
rmk | OutBackDingo: That's how I started but my nova compute node was not on the master and my vms were failing to start. | 18:35 |
rmk | When I moved the compute domu to the master, they started up, but only on the master. | 18:36 |
comstud | the compute node can run anywhere | 18:36 |
comstud | even on a physical box | 18:36 |
deshantm | "a) there is no concept of pools in OpenStack and XenServer; b) the XenAPI Plugins are required on each node making up your compute fabric." | 18:36 |
comstud | It just needs API access | 18:36 |
rmk | deshantm: Well for b), I'd assumed that and placed the plugins on each xenserver in the pool. | 18:37 |
OutBackDingo | right | 18:37 |
OutBackDingo | as did i | 18:37 |
*** nacx has quit IRC | 18:37 | |
OutBackDingo | i also created the /boot/guest on each host | 18:38 |
rmk | one piece missing in that xenserver document is that the hv needs to be installed using the thin provisioning option | 18:38 |
OutBackDingo | rmk: whys that? | 18:39 |
deshantm | rmk: can you elaborate as to why that is a requirement | 18:39 |
deshantm | rmk: back to your current problems though... If you are using trunk after September 8th, that is unstable/essex | 18:45 |
deshantm | there was a diablo branch created | 18:45 |
deshantm | which is just for stabilizing for the diablo release | 18:45 |
deshantm | http://wiki.openstack.org/DiabloReleaseSchedule | 18:45 |
rmk | I started using ppa:nova-core/milestone | 18:45 |
deshantm | http://osdir.com/ml/openstack-cloud-computing/2011-09/msg00158.html | 18:47 |
OutBackDingo | rmk: the only thing i can think of is when compute launches an instannces its passing the uuid of the host to launch on | 18:49 |
OutBackDingo | if not i see no reason why it would care about pooled or unpool as long as it could communicate to xapi | 18:49 |
*** ejat- has joined #openstack | 18:50 | |
OutBackDingo | consider also where is the vms virtual disk located, one shared storage, so once the vm is created it should in theory be able to be launched anywhere on the pool | 18:51 |
rmk | OutBackDingo: How do you even specify which SR gets used for VMs? | 18:55 |
rmk | Through openstack, that is | 18:55 |
rmk | All of mine have been getting created on local disk | 18:55 |
OutBackDingo | rmk: xapi deciphers the default primary shared sr | 18:55 |
*** ejat- is now known as ejat | 18:55 | |
*** ejat has joined #openstack | 18:55 | |
OutBackDingo | theres a tag on the sr that specifies it as default | 18:56 |
OutBackDingo | rmk: all of you what ? | 19:01 |
*** rsampaio has joined #openstack | 19:01 | |
rmk | all of my openstack-created vms | 19:01 |
rmk | they're being created on local storage, even though there's an nfs sr for the pool | 19:01 |
OutBackDingo | rmk: is the nfs sr set tp default ? | 19:03 |
*** threefish has joined #openstack | 19:03 | |
rmk | yes | 19:03 |
rmk | at least xencenter see's it as the default | 19:03 |
OutBackDingo | xe pool-param-get param-name=default-SR uuid= | 19:04 |
OutBackDingo | rmk: weird, cause whenever i create/import a vm its created on the default sr | 19:05 |
rmk | right whatever I create via xencenter is going to the nfs sr | 19:06 |
rmk | but openstack is using local disk | 19:06 |
OutBackDingo | the only think i see openstack nova create is a single bootfile | 19:06 |
OutBackDingo | rmk: can you check what vm images are on the default nfs pool | 19:07 |
rmk | yeah so xe pool-list shows the uuid of my nfs sr as the default | 19:11 |
rmk | btw that's a shortcut for what you were getting at (noticed it while looking for the uuid of the pool) | 19:12 |
