#openstack-nova - 2020-10-09
16:04:14 sean-k-mooney its set by https://docs.openstack.org/nova/latest/configuration/config.html#api.dhcp_domain
16:04:51 admin0 it does not say if it can be left null
16:05:00 sean-k-mooney i dont think it can be
16:05:48 sean-k-mooney although we have exampel of it being empty
16:06:27 sean-k-mooney we use it like this
16:06:28 sean-k-mooney https://github.com/openstack/nova/blob/58636d34ec68d44952b22947bac01d4b88ae103a/nova/api/metadata/base.py#L533-L536
16:06:56 sean-k-mooney you would have to set it to ""
16:06:58 sean-k-mooney https://github.com/openstack/nova/blob/85c35b4d9d6386866ddf197e4a751f729b726188/nova/conf/api.py#L218-L222
16:07:04 sean-k-mooney but i dont know if that wil work or not
16:07:14 sean-k-mooney default might still replace ""
16:07:18 sean-k-mooney but it would be easy to test
16:07:34 sean-k-mooney just set [api]/dhcp_domain=""
16:12:42 melwitt it can be blank. we had it set that way at yahoo
16:35:07 stephenfin sean-k-mooney: No, it wasn't helpful. You can't disable the built-in PS2 devices
16:35:23 stephenfin However
16:35:38 sean-k-mooney you cant by generating model=none in the xml
16:36:00 stephenfin I don't think that's supported. The only RFE I found for it was DEFERRED
16:36:40 sean-k-mooney well the perfromacne team teh filed teh orignal downstream issue had said they disabeld it manually by editing the xml
16:37:02 stephenfin they were talking about USB devices
16:37:15 sean-k-mooney yes
16:37:32 stephenfin you won't get a USB keyboard or pointer device on x86 unless you request them via image metadata properties or nova.conf
16:37:52 stephenfin so all that's necessary is to remove the superfluous USB bus
16:37:52 sean-k-mooney no libvirt will add it
16:37:59 stephenfin not a USB one, it won't
16:38:08 stephenfin it'll add a PS2 mouse and keyboard
16:38:11 stephenfin not USB
16:38:22 sean-k-mooney ok but i think they wanted to remvoe that too
16:38:41 stephenfin See above. I don't think that's supported
16:39:01 sean-k-mooney ya so your proposing what use virtio?
16:39:04 sean-k-mooney or ps2
16:39:05 stephenfin nope
16:39:22 stephenfin I've four patches
16:39:23 sean-k-mooney they are hoping to remove all interupts related to the input device
16:39:40 stephenfin first one is to remove the unnecessary USB bus
16:40:54 stephenfin With that, you can set '[compute] pointer_model' to 'none' or 'ps2mouse' and, unset the 'hw_pointer_model' image metadata property prop, and ensure you haven't set 'hw_*_bus' to 'usb'
16:41:05 stephenfin and you won't have any USB devices or a USB bus
16:41:18 stephenfin the second is a cleanup patch
16:41:31 sean-k-mooney well we dont want this to be in the nova.conf really
16:41:38 sean-k-mooney that will cause issue for live migation
16:41:51 stephenfin the third makes it so that we only attach a USB tablet if graphics (SPICE or VNC) are enabled
16:41:58 stephenfin because it's useless otherwise
16:42:20 stephenfin and the fourth adds support for virtio devices because they're supposed to be far more performant and it was an easy win
16:43:00 stephenfin Agreed. However, I can't remove it until you add that system metadata thing for Q35
16:43:37 sean-k-mooney :( ya
16:44:18 sean-k-mooney ok we might want to update the downstream bz to say the input device cant be removed but we are goign to do this instead
16:44:53 stephenfin I don't think the PS2 device is a massive issue. It's the USB bus that was doing most of the damage
16:45:01 stephenfin But I should check again to be sure
16:45:10 stephenfin Monday! For now, it's sunny outside so o/ :)
16:45:51 sean-k-mooney i guess thre expect result was actully "no USB and no graphics"
16:46:09 sean-k-mooney so ps2 device or virtio might be fine actully
16:46:18 openstack bugzilla.redhat.com bug 1787442 in documentation ""Configuring Real-Time Compute" lacks guest device configuration tuning" [Unspecified,Closed: wontfix] - Assigned to stephenfin
16:46:18 sean-k-mooney based on https://bugzilla.redhat.com/show_bug.cgi?id=1787442
16:50:53 admin0 sean-k-mooney, i made it blank and it still gives me a .novalocal
16:51:00 admin0 is that something from neutron in dhcp ?
16:51:47 sean-k-mooney no i think since novalocal is the default of that coning option you have to do =""
16:51:55 sean-k-mooney i dont think blank will actully work
16:52:40 sean-k-mooney melwitt: do you recal if ye set dhcp_domain= or dhcp_domain=""
16:52:56 melwitt dhcp_domain=""
16:53:07 melwitt set to empty string
16:53:30 melwitt sorry, that's what I meant when I said "blank" earlier
16:55:21 sean-k-mooney ya ok that makes sense
16:55:39 sean-k-mooney dhcp_domain= i think will be treated like its unset and the default will be used
16:56:06 sean-k-mooney admin0: this might only take effect for new vms too
16:56:35 admin0 unless i can modify the dhcp config manually
16:56:38 sean-k-mooney for existing vm i think we store there hostname in the db
16:57:18 sean-k-mooney you would need to update the instnace.hostname filed in the db
