| 09:41:02 | Uggla_ | bauzas, ^ should fix what we discussed, I have added what I have done for scaphandre as well on top of the serie. | |
| 09:47:42 | Uggla_ | bauzas, I need to test a couple of things with devstack, then I will try to reorganize the serie to have the API related stuff on the top. | |
| 10:09:09 | opendevreview | Michel Nederlof proposed openstack/nova master: Add ability to flatten RBD disks upon clone https://review.opendev.org/c/openstack/nova/+/884595 | |
| 10:15:53 | bauzas | Uggla_: ack, cooking now | |
| 12:54:08 | Uggla_ | sean-k-mooney[m], can you please remember me the issue with numa and memfd. So far I understand that tweaking numa is not required anymore with As of QEMU 5.0.0 and libvirt 6.9.0. Do I miss something ? | |
| 12:56:07 | sean-k-mooney | i discovered that recently too | |
| 12:56:27 | sean-k-mooney | so your rigt with a new enough qemu memfd does not require numa to be configured | |
| 12:56:42 | sean-k-mooney | so we could start makeing that our default memory backend in nova/libvirt | |
| 12:57:17 | sean-k-mooney | specificaly our default coudl evolve to | |
| 12:57:20 | sean-k-mooney | <memoryBacking> | |
| 12:57:22 | sean-k-mooney | <source type="memfd"/> | |
| 12:57:24 | sean-k-mooney | <access mode="shared"/> | |
| 12:57:26 | sean-k-mooney | </memoryBacking> | |
| 12:57:52 | sean-k-mooney | that will enable virtio fs and vhost-user to start workign automaticlaly without any special addtional configuration | |
| 12:58:38 | sean-k-mooney | Uggla_: however our current min qemu is 4.2.0 or declared next min is 5.2.0 | |
| 12:58:52 | sean-k-mooney | so we need to actuly raise the min version befoer we do that | |
| 12:59:21 | sean-k-mooney | kashyap was ment to be workign on that but i have not seen any patches yet | |
| 13:02:08 | Uggla_ | sean-k-mooney, as a reminder for virtiofs I require a qemu > 5.0.0 and libvirt > 6.2.0. | |
| 13:03:22 | Uggla_ | sean-k-mooney, anyway assuming I find the time to do it, any objection to write a spec for memfd ? (so we could review it at PTG ?) | |
| 13:04:06 | sean-k-mooney | go for it | |
| 13:04:27 | Uggla_ | sean-k-mooney, thx | |
| 13:04:48 | sean-k-mooney | what i have proposed in the past is adding hw:memory_backend=file|anonumous|memfd|hugepage | |
| 13:04:59 | sean-k-mooney | and if we raise the min then memfd can be the default | |
| 13:05:04 | sean-k-mooney | when its not set | |
| 13:05:43 | Uggla_ | what is anonymous ? | |
| 13:05:56 | sean-k-mooney | what we use today just speeled incorrectly | |
| 13:06:01 | sean-k-mooney | non shared 4k pages | |
| 13:07:46 | Uggla_ | ok you think there will be no "side effect" to switch to memfs as default ? | |
| 13:08:13 | sean-k-mooney | there are sideeffect but i think its a better default. provided we have a new enoguh qemu | |
| 13:08:24 | sean-k-mooney | specificly im suggeting changin two defaults | |
| 13:08:42 | Uggla_ | ok | |
| 13:09:03 | sean-k-mooney | hw:memory_backing=memfd which im suggeting should be the new default woudl set <source type="memfd"/> and <access mode="shared"/> | |
| 13:09:12 | sean-k-mooney | the <access mode="shared"/> is the main delta | |
| 13:09:34 | sean-k-mooney | memfd ensure there is a file decriptor allcoated to the memory segment | |
| 13:10:33 | sean-k-mooney | combinded with <access mode="shared"/> that means dpdk or or other tools that do security scaning tools can map the guest memory an acess it form the host | |
| 13:11:06 | sean-k-mooney | so that will enabel ovs-dpdk to work out of the box without requiring the vm to use hugepages or file backed memory | |
| 13:11:21 | Uggla_ | cool ! | |
| 13:11:41 | sean-k-mooney | and it will make virtio-fs work which is your main usecase enable but the maniall share work you are doing and the scaphanda work | |
| 13:12:19 | sean-k-mooney | the reason for keeping anonymous is for those that dotn what <access mode="shared"/> | |
| 13:12:29 | Uggla_ | yep, it might simplify the host config too. | |
| 13:13:13 | Uggla_ | sure, it good to keep anonymous for people who does not want to use shared mem, for any reason. | |
| 13:13:18 | sean-k-mooney | yes so put to gether a spec and we can debate the default in it but i would be infavor of using memfd as it has may advantages | |
| 13:14:26 | Uggla_ | I agree, will do that. | |
| 13:15:09 | Uggla_ | Another thing, I'm not sure you have seen my note yesterday about virtofs not supporting readonly. Do you thing proposing virtio9p as an alternative to virtiofs could be useful ? | |
| 13:15:41 | Uggla_ | or we should just wait virtiofs to support it ? | |
| 13:17:29 | sean-k-mooney | virtio9p does not apprer to be supported by libvirt | |
| 13:18:31 | sean-k-mooney | oh | |
| 13:18:36 | sean-k-mooney | its an atribute you can set 9pfs | |
| 13:18:42 | Uggla_ | hum are you sure, I can configure it using virtual machine manager, and I think it uses libvirt. | |
| 13:21:19 | sean-k-mooney | it might be setting things qit qemu args | |
| 13:23:40 | Uggla_ | it looks like the conf is: https://paste.opendev.org/show/bC6FS8a7RP2J0tT9G2Jn/ | |
| 13:24:42 | sean-k-mooney | ya so it looks like its the defautl driver if you dont use virtio-fs | |
| 13:26:22 | Uggla_ | I have not dig into it, this is just the conf porposed by virtual machine manager. I'm a bit afraid about the <address type="pci"... as I don't really know the purpose so far. | |
| 13:26:29 | sean-k-mooney | im not sure that readonly is really required but perhaps we should consider it | |
| 13:26:58 | Uggla_ | sean-k-mooney, I have discussed and open a ticket to the virt team to have it supported. | |
| 13:27:03 | sean-k-mooney | Uggla_: thats just the adress in the vm where its mounted | |
| 13:27:18 | sean-k-mooney | Uggla_: we can rely on it however fo the intial enablement | |
| 13:27:39 | sean-k-mooney | we have a policy of rquiring features to be in a released version of libvirt/qemu before we can use it in nova | |
| 13:28:10 | sean-k-mooney | i woudl perhaps isnteead consier addign ahard limit on the virtiofs size and allwo it to be read write | |
| 13:28:18 | sean-k-mooney | but lets see what others think | |
| 13:33:58 | Uggla_ | one of the benefits is that virtio9p seems to not have issue with snapshot etc... but probably less performant than virtiofs. | |
| 13:35:00 | Uggla_ | I think virtio9p does not require shared memory that's the reason why. | |
| 13:38:17 | Uggla_ | sean-k-mooney, regarding virtiofs if we really want ro we can work around it using a bind mount and explain it it the doc. | |
| 13:39:33 | Uggla_ | sean-k-mooney, do you thing it worth to also write a spec for virtio9p ? | |
| 14:13:19 | sean-k-mooney | no | |
| 14:13:28 | sean-k-mooney | i dont think we shoudl add supprot for virtio9p | |
| 14:13:49 | sean-k-mooney | it has much lower performacne and it will likely get remvoed eventully once virtiofs has reach feature partiy | |
