Title:
Minimal Ubuntu vs. Debian differences
Status in QEMU:
Expired
Bug description:
I'm using Qemu on Ubuntu (minimal) and Debian (minimal) on Android
(Arch64) via Linux Deploy to run Windows guests. Here's a few issues I
encountered:
1) Qemu on (minimal) Debian 9 and Ubuntu cannot run Windows 7-10
guests (only Windows XP and below) because there's a black screen
after the boot menu. Qemu on Debian 10, however, can run Windows 7.
Incidentally, these distros run on the host in bios compatibility mode
instead of UEFI. Ubuntu Desktop (full distro) on other hosts does not
display the black screen when running Qemu.
2) Qemu on Debian 9-10 (minimal) does not display fullscreen - but
Ubuntu minimal does display full-screen.
3) Qemu on Limbo PC Emulator and on Debian 9-10 only run windows
guests at 1 GHz using the default Qemu CPU, but Ubuntu runs windows
guests at 2 GHz using the default Qemu CPU.
4) Enable KVM doesn't work, and virtualization isn't detected through
Limbo PC Emulator and minimal Linux distros running on Android -
perhaps is a problem with running Linux distros via Linux Deploy using
Chroot on Android (not so much a Qemu-KVM issue) and failing to detect
ARMv8-A CPUs that are indeed capable of virtualization.
Can anyone explain these differences? I believe they are all using the
latest versions of Qemu.
