install fedora-38 loongarch64 on x86_64 HOST with qemu-system-loongarch64

24 Aug 2023

qemu-system-loongarch64 is available on Fedora-38

Found that qemu-system-loongarch64 has been added in default Fedora-38 repo, so we can try to start the loongarch64 distribution on our x86_64 HOST with qemu-system-loongarch64.

tips

  • option ‘-vga std’ is necessary for higher screen resolution

note: libvirt: Request for supporting loongarch architecture

We can’t use virt-install/kiss-vm yet to install loongarch64 virtual machines, because libvirt loongarch64 support has not pushed to upstream.
