how to enable KVM on Armbian ?

I think most important is that people make sure they can fix their own issues if a HW/computer fails. I found high-availability interesting, but for just my house (or even 2 places/countries at the same time) I found it too much to make it all work. The thing I could maybe use is DRDB, however I see v9 is under development since 2011 and it still is not in mainline kernel. Compared to that I have some script to transfer latest differential Btrfs snapshot from 1 computer to the other on-the-fly, I doubt I can really benefit from DRDB, but maybe I set up a test and see what it does. I use only ARM64 for 24/7 servers, so no x86_64 <=> ARM64 incompatibility. So same as for ZFS for example, it is external to Linux distro and my experience is that complicated issues/failures always happen at the wrong moment, e.g. also no internet and/or mains power failure etc. So I try to minimize the amount of 'external' HW/SW modules, certainly if the backing company is commercial and in whatever country far away from where I am. Proxmox is nice, but also 'external'. Same for even Docker, so I have actually no such containers. But it all depends on how much you are involved in various HW and SW. As you can see in my earlier message, I already forgot HA was available as generic aarch64 image, so that says enough. I use several custom (own) HW (like 'changed' solar inverter) and HomeAssistent does not support it, so I actually do not really use it. It is mostly C-code and Node-RED in conjunction with various micro-controllers. A good test is to disconnect internet (power-off fiber-RJ45 box in my case) and/or also do an ad-hoc power cut (no cheating with UPS). And then see if you can get it all running again within a certain time frame (what you think is acceptable, like before temperature in freezer gets > -10 or so).

@humanus You are a very nice guy!

Hi team, I am on the latest vendor release of gnome installed via armbian installer. Kernel is linux-image-6.1.115-*-rk2410. When I look for audio drivers I do not see card 3: rockchiphdmiin [rockchip,hdmiin], device 0: fddf8000.i2s-dummy_codec hdmiin-dc-0 [fddf8000.i2s-dummy_codec hdmiin-dc-0] Subdevices: 1/1 Subdevice #0: subdevice #0 I got the board very recently and the forum is a little mesay about the hdmi rx functionality. It would be a great help if anyone can help me out on this, let me know if i am missing anything.

The eMMC is still not detected. Kernel log: [ 4.621568] mmc2: error -110 whilst initialising MMC card [ 4.627066] mmc2: Failed to initialize a non-removable card Working devices: [ 4.502846] mmc0: new high speed SDXC card at address aaaa [ 4.508907] mmcblk0: mmc0:aaaa SC64G 59.5 GiB [ 4.551951] mmc1: new high speed SDIO card at address 0001 The system boots correctly from the SD card, but the onboard eMMC (mmc2) is not initialized. There are also still Ethernet issues. After connecting through PuTTY, the system sometimes hangs when running dmesg, and the network connection becomes unstable or unresponsive. System information: Thanks
