Re: qemu and raspberrypi
Hi Marco, I haven't tried it myself but the Raspberry Pi 2 is a supported machine: https://wiki.qemu.org/Documentation/Platforms/ARM and $ qemu-system-aarch64 -machine help | grep raspi raspi2 Raspberry Pi 2 Generally you can follow any tutorial on creating a Raspbian VM using qemu. It doesn't matter whether the host is an ARM or x86. Also Raspbian is basically Debian, so most info you find for Debian is likely also valid for Raspbian.

Do you live on the US East Coast? ;-P Try telling Windows that its BIOS is using UTC: https://superuser.com/questions/975717/does-windows-10-support-utc-as-bios-time Alternatively you can tell qemu to use local time as the RTC base: https://qemu-project.gitlab.io/qemu/system/invocation.html (grep for -rtc) -- Philipp

Cirrus should work fine with the stock drivers included in Windows. Personally I'm using vmware with the official VMware driver. You can extract the driver for Win9x from preWin2k.iso shipped with VMware. Bonus: set vmport=on (may be default) an install the vmmouse driver from said ISO, and try vmxnet3 if you need networking.
ATAPI Passthrough or how to expose a CD drive to a VM
Dear List! I'm looking for a way to plug a CD drive's SATA cable into the virtual SATA controller in the guest, i.e. pass through a single SATA port. Unfortunately that doesn't seem to be possible. The next best thing is to pass through ATAPI commands from the guest to the physical CD drive. The reason is that I want to run Exact Audio Copy (EAC) in the guest to create bit-perfect copies of my audio CDs (which is a surprisingly hard thing to do!). EAC (and IIRC CDDA reading in general) sends low-level ATAPI commands to the CD drive, which is why I want to pass them through. When searching for this I found this thread from 2009~10: https://qemu-devel.nongnu.narkive.com/HNXMnx1m/patch-0-7-atapi-cdrom-passthrough-v5 There is also this patch from 2015: https://github.com/brendank310/meta-qemu-1.4-oxt/blob/master/recipes-openxt/qemu-dm/files/atapi-pass-through.patch I was wondering if this has ever made it into qemu and if so how to enable it. The only remaining option I see is buying a PCIe-SATA controller and passing the entire controller to the VM. Do you folks have any ideas here? Thanks! Philipp
Re: Strange behavior by qemu and the VM console.
Hi George, did you recently upgrade your DE or mess with your DPI settings? In the GTK window, there's an option "zoom to fit" (or similar, I don't have it in front of me ATM). Make sure that is disabled.

I suspect the headache will be bigger than the benefit ;-) I'd use vmmouse. You need to set vmport=on and install the drivers. This is also mentioned here: https://www.linux-kvm.org/page/Guest_Support_Status You can find the drivers on winPre2k.iso. That ISO is included with VMware Player. If you choose that route can also use VMware SVGA (-vga vmware) and possibly VMXNET3 (-net nic,model=vmxnet3; I haven't tried). BUT: The EULA might forbid you to use those drivers on anything other than VMware. However, I'm not sure this applies in the EU because of interoperability laws. I'm not a lawyer, you have to decide for yourself.
USB support in microvm
Hi, I'm trying to add an USB controller to a microvm. Background: I need to pass a USB network controller to the guest. The trouble is that all USB controllers use the PCI(e) bus, which isn't supported by microvm. It should be possible though: the Raspberry Pi < 4 has USB support without PCI. (How) is it possible to use USB in microvm? Thanks! Philipp
