From 600f9b20311b7bf15a9956de8009d53af60e97e5 Mon Sep 17 00:00:00 2001 From: Giulio Fidente Date: Fri, 16 Dec 2016 21:52:13 +0100 Subject: Increase libvirt/qemu.conf max_files and max_processes When Nova and/or Cinder are using Ceph as backend, qemu will need to open a connection and two threads for each and every Ceph OSD. This change raises the max_files (set to 1024 by default) to 32768 and the max_processes (set to 4096 by default) to 131072. The max number of FDs is per-process, while the max number of processes is per-user. The values can be overridden via ExtraConfig, no params are added to the templates. A more detailed description of the values were chosen can be found at: https://access.redhat.com/solutions/1602683 Change-Id: I1e79675f6aac1b0fe6cc7269550fa6bc8586e1fb Depends-On: I258afd3ee6633e4b2ebc45aa8611be652476be0c --- puppet/services/nova-libvirt.yaml | 3 +++ 1 file changed, 3 insertions(+) diff --git a/puppet/services/nova-libvirt.yaml b/puppet/services/nova-libvirt.yaml index 70774bac..6cf348bb 100644 --- a/puppet/services/nova-libvirt.yaml +++ b/puppet/services/nova-libvirt.yaml @@ -50,6 +50,9 @@ outputs: tripleo::profile::base::nova::libvirt_enabled: true nova::compute::libvirt::services::libvirt_virt_type: {get_param: NovaComputeLibvirtType} nova::compute::libvirt::libvirt_virt_type: {get_param: NovaComputeLibvirtType} + nova::compute::libvirt::qemu::configure_qemu: true + nova::compute::libvirt::qemu::max_files: 32768 + nova::compute::libvirt::qemu::max_processes: 131072 tripleo.nova_libvirt.firewall_rules: '200 nova_libvirt': dport: -- cgit 1.2.3-korg
