Kernel-based Virtual Machine (KVM) has become the defacto hypervisor on GNU/Linux systems it works with great performance as it utilizes the CPU virtualization extensions Inetl VT-x or AMD-V). KVM doesn’t emulate hardware but uses QEMU for this.
Nested Virtual guest
It’s possible to use nested virtualization this make it possible to run a hypervisor inside a KVM virtual machine.
It was running pfsense and was quite happy about it. Pfsense dropped support for 32 bits in their pfsense 2.4 release.
This would left me with a unsupported firewall which was one of the reasons to use pfsense instead of a closed source commercial router.
I could have moved to a new firewall like the pcengines apu but there is no reason to replace hardware that works fine.
The nice thing about opensource software is that we’ve options to choose from if software doesn’t match your usecase we’ve other options to choose from.
On telephone network there are alternative internet providers but they use the network
of proximus.
I switched my internet connection from ADSL to VDSL and switched to a new provider ( edpnet).
The internet speed was below the expectations and my modem reported errors on the line. After fixing the internal phone cabbeling in my appartment I wanted the retrigger the DLM monitoring.
To start the DLM monitoring in Belgium you need to call 0800 22 424 and type in your line number. If you don’t have a proximus phone number the line number is not the same as your phone number. To get your line number you need to connect an analog phone to our line and call 1924 this will read aloud your line number.
When you create an new virtual KVM virtual system the video ram is limited to 16MB by default to use a higer screen resolution you need
to increase the video ram. The available resolution reported by the virtual screen may also not include the resolution that you want to
utilize.
You’ll find my journey to enable higher screen resolutions in my KVM (qemu) virtual systems below.
I used the relay host of my internet provider but this was causing issues since my email was getting mark as SPAM in gmail.
It was already on my to-do list to move my outgoing mail to my mail provider also to make it easier to move to another ISP or to implement SPF but was not on the top of my to-do list.
My email provider requires authentication, so I needed to reconfigure postfix in my FreeBSD mail jail to use a relay host with authentication.
