How to install QEMU

Quick Emulator (QEMU) is the main component of the QEMU/KVM virtualization technology suit. It provides hardware virtualization and processor emulation. QEMU runs in userspace and, without the need for kernel, drivers can still provide fast system emulation. The hardware acceleration support provided by the Kernel-based Virtual Machine (KVM) hypervisor.

Perform the following steps to install QEMU from packages on Ubuntu/Debian and RHEL/CentOS distributions:

On Ubuntu/Debian distributions, update your packages index:

root@kvm:~# apt-get update

Install the package:

root@kvm:~# apt-get install -y qemu-kvm

On CentOS/RHEL distributions execute:

root@kvm:~# yum install qemu-kvm

Installing QEMU is quite trivial, as we just saw. Let's have a look at what the QEMU metapackage installed on Ubuntu looks like:

root@kvm:~# dpkg --list | grep qemu

From the preceding output, we can see that there are few packages involved

How to replace Supermicro IPMI SSL and TLS Certificate

I decided to replace SSL and TLS Certificates at my Supermicro IPMI (Intelligent Provisioning Management Interface). Warning: Server will restart after cirtificate update ! There are many options how to create Certificates. Here is two options. One is for Linux and the second is for Windows. Let's start with Linux. To create certificate you need OpenSSL at your Linux installation. It's included in almost all distributives. To check version of OpenSSL use this command: #openssl version OpenSSL 1.0.2g 1 Mar 2016 I suggest to use at least 2048 bit certificate. First we create private 2048 bit RSA key. The filename can be any you wish, in this example I will store private RSA key in pvt.pem. #openssl genrsa -out pvt.pem 2048 or you can user genpkey option #openssl genpkey -algorithm RSA -out pvt.pem -pkeyopt rsa_keygen_bits:2048 Using this private RSA key I create Certificate Request #openssl req -new -key pvt.pem -out crt.pem Then I use my privat

How to configure IPMI from IPMICFG Utility

IPMICFG Overview IPMICFG is a utility for IPMI devices configuration. It is a command line tool providing IPMI commands and Supermicro proprietary OEM commands. It is designed for easy to use and no pre-installation required. Use it for basic IPMI configuration and BMC status reading and monitoring. Features: Set up IPMI IP Address Set up IPMI Configuration Configure IPMI User Management Configure IPMI FRU Manage System Event Log (SEL) Manage IPMI by node management (NM) protocol IPMICFG Linux version will automatically use linux built-in ipmi driver from ipmitool to access BMC. If there is no ipmi driver loaded, IPMICFG will use its internal API to access BMC. However, the performance will be slow. Note: You should use root permission to launch IPMICFG. Here is a step to load ipmi driver. You should be type these command to activate openIPMI driver: # modprobe ipmi_msghandler # modprobe ipmi_devintf # modprobe ipmi_si Installing IPMICFG # un

How to Enable Console at EVE-NG

By default EVE-NG disable console access. You can use VNC to get console access to VM. By editing GRUB_CMDLINE_LINUX in /etc/default/grub I've added console=tty0 console=ttyS0,115200 to enable console access using virsh console eve-ng command. GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200 net.ifnames=0 "
