I want to deploy openstack with nested virtualization enabled. Here is the scenatio, on bare metal I have one VM running as the host of openstack 7 VMs (KVM), and with the KVM VM I have one compute VM running.



I have achieved the half of the goal, I mean I have deployed the openstack successfully on my environment, but it slows down after approx. 12 hours and I need to destroy all the vms and start them again, and then everything works fine again.



I am using Ubuntu 16.04 OS, have 128 GB of RAM and 48 physical cores, I have tried overcommitting the CPUs with CPU pinning but that simplly didn't work.



Note: Current CPU model is host-passthrough, I have tried host-model which didn't work for me.



Any help will be appreciated. Thanks in advance. And please let me know if any more information is needed.,

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
