Re: [Openstack-operators] Nova

Mike that's just as I suspected. To be super clear, does KVM in particular know how to distinguish between Ubuntu v12 versus v16? In other words, do I need to be running a specific version of KVM hypervisor so it can host guests running the latest version of Ubuntu? Again, this was brought up as b

Re: [Openstack-operators] Nova

Hi Adam - The OS of the guest is independent of the Openstack version. Your choice of hypervisor (KVM, VMWare, HyperV, etc) would just need to support the OS version that you want to run on your guests. Mike Smith Lead Cloud Systems Architect Overstock.com On Sep 2, 20

Hey everyone, do specific versions of OpenStack necessitate specific versions of guest os's? I.e. if I'm running a mitaka cloud platform, do the guest vm operating systems need to be a specific version of Linux? My understanding is the two are totally unrelated when the VM's are running Linux but I

Does anyone have any database cleanup scripts (especially for Nova/Cinder) that they are proud of and are willing to share? Googling around didn't turn up anything I felt was trustworthy; I found one in a GitHub Gist and stopped reading as soon as it disabled foreign key constraints.

Re: [Openstack-operators] Delete cinder service

There is ‘cinder-manage db purge’ to delete entries which are marked as deleted. I never tried it (and suggest to start with a copy of the db before touching the prod ones). We usually do not purge databases unless we hit an issue. Cheers, Arne > On 02 Sep 2016, at 10:28, William Josefsson
