noob question about Templates

HI Sorry for the newbie question but . When creating a template - does enabling the HVM option allow the virtual machine to also be a hypervisor so that nested virtualization can be achieved? Gary Dixon Senior Technical Consultant T: +44 161 537 4990 E: [email protected] W: www.qua

System monitoring

Obviously a bit of a broad topic, but I'm curious what metrics people are using to monitor the health and performance of their Cloudstack installations? Disk space / total CPU load / load per core are the obvious ones. What are any of you doing from a network standpoint? Do you dig into traffic on

Re: noob question about Templates

Hey Gary, Welcome to the list. Firstly, which hypervisor are you using? HVM used to mean use hardware accelerated virtualization back in the day when it was still fairly new. It was required for some hypervisors, but not all. These days everything is hardware accelerated. If you are running KVM

RE: noob question about Templates

Hi Simon Thanks for the info - its quite interesting !! We are running KVM hypervisor on Ubuntu 20.04 on AMD EPYC cpu's We haven't been enabling HVM on templates as we don't want users to be able to nest hypervisors within their VM's Gary Dixon Senior Technical Consultant T: +44 161 537 49

Re: noob question about Templates

Yeah, I don't think you need to worry about it. Without the modprobe flag configured on the KVM host, it won't allow a nested VM to be deployed. -Si On Fri, Feb 10, 2023 at 10:51 AM Gary Dixon wrote: > > Hi Simon > > Thanks for the info - its quite interesting !! > > > We are running KVM hyperv

Cluster HA - KVM Hosts

Re: Cluster HA - KVM Hosts

Hey Jafar, For HA to work on KVM, you need to configure each host with out-of-band management using ipmitool or Redfish. This is so Cloudstack can fence your nodes. This covers the concept - https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html?highlight=fencing#ha-enabled-host
