    Since I have here two NIC’s – one for administration (1GBit), second one for VM machines (10GBit) – I choosed the vmbr1 interface bridge to get 10GBit on that. To achieve this I had to choose VirtIO (paravirtualized) which offers 10GBit Lan.

How-to convert Windows Server 2019 Evaluation to Windows Server 2019 Standard

Hi,

Recently we have bough a new Dell PowerEdge R640 server for my current company, where we have got Windows 2019 Server ROK key.

Since I wanted to use as primary OS Proxmox VE and then virtualize everything I just installed on VM Windows Server 2019 Evaluation Standard on it.

After some test with our company software, I was ready to activate the Windows Licence Key on that machine. The Windows activation procedure via GUI cannot use that key, so from the terminal I have done this:

(of course in /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX you have to enter your ProductKey)

After hiting Y the VM machine with Windows Server 2019 Evaluation restarted and stared to clean up some settings:

Windows Server 2019 Evaluation Activation

And after the reboot and login into the Windows Server 2019 I’ve got this:

Windows Server 2019 Standard Edition

And the system has been activated also

Problem connecting to KVM with Virt-Manager

Recently I have had some issues with connecting from my laptop running Linux OS (Fedora 30, Xubuntu 19.04) from virt-manager to server running KVM. Virt-Manager keeps asking me for root password, which was very annoying.

The solution was simple – first I had to create ssh keys which then I needed to send to my CentOS(7) server running KVM

After that I was able to use Virt-Manager without any asking for password.

How to install MS SQL Server 2017 on CentOS 7

There are many instructions and how-to’s regarding installing MS SQL Server 2017 on CentOS 7 but here are my notes about it:

  1. You should plan how to setup your CentOS 7 system because by default MS SQL Server hold his files in those directories:
    1. SQL Server 2017 file location after install
    2. database and others
    3. Of course this directories can be changed after install, but does anyone change directories for MySQL/PostgreSQL ?
  2. Read carefully documentation provided by Microsoft ®, especially this:
    https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-red-hat?view=sql-server-2017
    https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-performance-best-practices?view=sql-server-2017
    https://docs.microsoft.com/en-us/sql/linux/sql-server-linux-configure-mssql-conf?view=sql-server-2017
  3. Check if your software will work with MS SQL Server running on Linux. Some software will work but you will probably have no support if you run it that way.

Here is how I have setup my CentOS 7 to work with MS SQL Server only

  1. I have created Virtual Machine which has:
    2 x CPU’s
    8 GB of RAM
    100 GB of space
    1 x NIC
  2. Disk partitioning:
    /boot – 1024 MB
    / – 30 GB
    /var – 60 GB
    /tmp – 5 GB
    /var/log – 5 GB
    /swap – 8192 MB
  3. CentOS 7 setup
    1. Update system
    2. Enable EPEL repo (not necessery, but I like to have it)
    3. Download MS SQL Server 2017 repo
    4. Install
    5. Setup
  4. Enabling TCP port on firewall
  5. Connecting from SQL Management Studio
    1. Logon screen
    2. After logon screen

I think this is all … for now 😉 I will try to write something more after I will test it in production.
