Yes, as you mentioned in your follow-up email, your virtual machine was trying to boot from the hard drive after it was partitioned but before it was formatted and SYS'ed. Your follow-up said you fixed this by using "-boot d" (disc) to force QEMU to boot from the CDROM. You could also have hit Esc during the BIOS menu to select the boot device. But I don't know if this "virt-manager" activates the BIOS menu. > > I had forcibly stopped the machine on Debian 11, and when rebooting Debian 11 > itself, it took 2 or 3 mins to try to let qemu process die. > Yes, I had a similar problem when I used GNOME Boxes (another front end to QEMU on GNOME) and tried to abort something. The QEMU process would hang around for a while, and I'd have to "kill -9" the process. That's one reason I stopped using GNOME Boxes and ran QEMU directly from the command line. If I have to abort QEMU, I know it's stopped. > > BTW: > 2021-06-13T01:27:09.703704Z qemu-system-x86_64: -usbdevice mouse: > '-usbdevice' is deprecated, please use '-device usb-...' instead > WARNING: Image format was not specified for > '/home/paul/lib/freedos/freedos.img' and probing guessed raw. > Automatically detecting the format is dangerous for raw images, > write operations on block 0 will be restricted. > Specify the 'raw' format explicitly to remove the restrictions. > 2021-06-13T01:27:09.723897Z qemu-system-x86_64: warning: '-soundhw pcspk' is > deprecated, please set a backend using '-machine pcspk-audiodev=<name>' > instead > These are safe warnings; I get these too. QEMU is always updating the command line, and they are changing how to specify a USB mouse. Same for how they are changing the PC speaker emulation. The image format being probed "raw" is another warning that's been there for a while. It's interesting because the QEMU documentation says you can use "-hda" to specify an image file, but then they give you this warning that you didn't specify the file is a raw image. But it correctly guessed it's a raw image, so you can ignore this warning safely.
