Hello,
I would like to build a hyperconverged gluster with hosted engine in a virtual environment, on Fedora 33 with KVM.
The setup is for testing purposes, specially for test upgrades before running them on the real physical Servers. But I want to have the setup as close as possible to the real environment, so the only thing is missing is a fence agent.
Is there a way to simulate power management in a virtual environment?
I had successfully used the following approach not much time ago: # Setup power management for VMs: at hardware host install: ``` yum install python-pip -y yum install -y zeromq-devel yum install -y gcc python-devel libvirt-devel firewall-cmd --permanent --zone=public --add-port=623-624/udp firewall-cmd --reload vbmc add CentOS7-ovirt0 --username root --password yourpass --port 623 vbmc add CentOS7-ovirt1 --username root --password yourpass --port 624 [root@baremetal ~]# vbmc list +----------------+--------+---------+------+ | Domain name | Status | Address | Port | +----------------+--------+---------+------+ | CentOS7-ovirt0 | down | :: | 623 | | CentOS7-ovirt1 | down | :: | 624 | +----------------+--------+---------+------+ [root@v2 ~]# vbmc start CentOS7-ovirt0 2019-10-16 18:44:57,397.397 26596 INFO VirtualBMC [-] Started vBMC instance for domain CentOS7-ovirt0 [root@v2 ~]# vbmc start CentOS7-ovirt1 2019-10-16 18:45:38,056.056 26596 INFO VirtualBMC [-] Started vBMC instance for domain CentOS7-ovirt1 [root@v2 ~]# vbmc list +----------------+---------+---------+------+ | Domain name | Status | Address | Port | +----------------+---------+---------+------+ | CentOS7-ovirt0 | running | :: | 623 | | CentOS7-ovirt1 | running | :: | 624 | +----------------+---------+---------+------+ at node0 host (VM) check: ipmitool -I lanplus -U root -P yourpass -H <hardware host IP> power status (default port is 623) ipmitool -I lanplus -U root -P yourpass -H <hardware host IP> power status -p 624 at ovirt GUI you need lanplus=1,-p623 and lanplus=1,-p624 options for each host. ```
